We look forward to welcoming you to stand E4.02 at Warsaw HVAC EXPO.

Come and see how akYtec’s smart automation and IIoT solutions can make your system more connected, efficient, and secure.

The chiller control system based on the PR205 provides coordinated, efficient, and protected operation of cooling equipment with up to four compressors, electronically controlled expansion valves, and a condenser fan. Designed for reliability and operational clarity, the system manages all essential refrigeration processes, monitors critical pressures and temperatures, and ensures safe and optimized performance in all operating conditions.

At startup, the system remains in standby until a remote start command is received. It then automatically performs a safety check of all monitored conditions. Operation begins only if no alarm is active; otherwise, the system alerts the operator to the fault and remains locked until manually reset. This ensures that the chiller never begins operation under unsafe or unknown conditions.

During normal operation, the controller continuously evaluates cooling demand and activates compressors in stages. Each compressor is started only after a defined delay, and the controller always selects the unit with the lowest accumulated running hours to promote balanced wear. As demand increases, additional compressors are engaged sequentially; as demand decreases, the system identifies and shuts down the compressor with the highest operating hours, but only when the load has fallen sufficiently below its stage threshold. This approach minimizes cycling, extends service life, and adapts output to real-time load conditions.

The electronic expansion valve is regulated through a dedicated control algorithm that maintains stable superheat and protects the compressor. Valve opening is adjusted dynamically based on cooling conditions and the number of active compressors. The controller automatically selects optimal control parameters depending on whether the system’s superheat is within its normal range, above it, or below it. In cases where suction pressure rises excessively, the system switches to a protective control mode to stabilize operation and prevent potential compressor damage.

Condenser fan operation is likewise optimized. The fan engages only when discharge pressure exceeds a defined threshold and then modulates its speed proportionally to maintain safe and efficient condenser conditions. This reduces unnecessary energy consumption and maintains consistent operational stability.

To further protect the system, a high-pressure warning stage is implemented. When discharge pressure approaches a critical limit, the controller issues a visual warning and temporarily reduces the cooling output request, lowering compressor load enough to bring pressures back into safe range. This preventive action avoids unnecessary system shutdowns and reduces thermal stress on the refrigeration circuit.

If any monitored parameter — such as suction pressure, discharge pressure, or compressor superheat — exceeds its allowable range for longer than the permitted delay, the system enters a locked-out state. In this condition all operation stops, an alarm is raised, and manual acknowledgment is required before the chiller can be restarted. Special handling is included for superheat monitoring during compressor startup to avoid nuisance alarms.

Together, these functions form a robust and intelligent control platform that ensures reliable cooling performance, balanced utilization of mechanical components, and comprehensive protection of the refrigeration system. The PR205-based architecture delivers operational transparency, predictable behavior, and long-term system stability — making it a strong foundation for modern chiller applications in commercial and industrial environments.

Programmable relays

AkYtec's ITP15-M and ITP17 indicators provide intuitive, accurate, and instantly readable data displays — whether you need quick visual assessment via a backlit scale or detailed numeric values with color-coded alerts. Designed for harsh maritime conditions, these devices support faster decision-making, reduce human error, and help keep vital ship systems running safely and efficiently.

AkYtec solutions for shipboard control: accuracy, speed, safety

In environments with limited space, noise, vibrations, and a high level of responsibility for the safety of the vessel and crew, it is crucial that the parameters of controlled systems are immediately understandable — without decoding or delays.

AkYtec designs and manufactures digital indicators tailored to the demanding conditions of shipboard and industrial environments, ensuring clear, stable, and accurate visualization of technological parameters.

Why is visualization critical on ships?

On board a ship, operators must instantly understand the current status of systems without wasting time deciphering signals or navigating complex interfaces. Errors in interpreting information can lead to accidents, equipment overheating, flooding, or even loss of control of the vessel.

Therefore, devices must:

• Display accurate values (temperature, pressure, level, etc.)
• Highlight deviations from the norm
• Be visible in all conditions (day/night, vibrations, humidity)

AkYtec solutions: ITP15-M and ITP17

ITP15-M — digital indicator with an analog scale

• Linear scale with backlighting (segments)
• Quick assessment: normal or deviation?
• Compact design
• Connects to level, pressure, and temperature sensors
• Ideal for pump stations, holds, and boiler rooms

Perfect for locations where visual assessment is key — without needing to read numbers.

ITP17 — indicator with a digital display and color-coding

• Displays parameters in digits and units of measurement
• Three display colors: green (normal), yellow (warning), red (alarm)
• User-configurable thresholds and color zones
• Compatible with a wide range of sensors: current, voltage, thermocouples, RTD, pyrometers
• Includes a transistor output for control (pumps, signals, etc.)

Convenient for centralized control rooms, engine rooms, and control cabinets.

Where akYtec indicators are used on ships

• Ballast water control — liquid level, pump activation
• Ballast and fuel tanks — level, temperature, pressure
• Cooling and ventilation systems — environmental temperature, fan speed
• Power and engines — current, voltage, overload
• Ship’s boilers and steam systems — steam temperature, water pressure

AkYtec solution advantages

The ITP11 is one of the most reliable and efficient loop-powered indicators in akYtec’s product range. But what makes it so successful over the years? Let’s explore its working principle and applications in more detail.

Principle of Operation

A loop-powered indicator is a measuring device that operates using the current signal in the range of 4…20 mA. It displays real-time data received from sensors measuring pressure, temperature, regulators, switches, actuators, and valves.

The ITP11 indicators come in two design formats:

1. ITP11 – Mounted directly into a 22mm button hole on the control panel.
2. ITP11-W – Can be mounted either on a control panel or on a pipe.

Users can configure various signal processing and display parameters, including minimum/maximum values, scaling, time delays, and signal damping.

Purpose of Loop-Powered Indicators

Loop-powered indicators serve as measurement devices that process analog signals from sensors or other equipment with a 4…20 mA output. Their primary function is to display measured physical parameters on a digital screen or integrate them into a data communication system. In some cases, they can also generate control signals for external devices.

Industrial Applications

These indicators are widely used in industrial automation and process control systems as local measurement units for primary sensors with a 4…20 mA output. They are commonly applied in:

• Temperature and humidity control systems in industrial facilities.
• Automation in oil refining and distribution plants.
• Production lines for construction materials.
• Pumping stations for various purposes.
• Water treatment, purification, and wastewater management in municipal and industrial sectors.
• Boiler automation systems.
• Industrial complexes for building material production.

Working Principle

A loop-powered indicator connects in series with the 4…20 mA signal circuit between a sensor and an analog input device (e.g., ITP11). It converts the current signal into a digital display output based on user-defined settings. Programming is done via buttons on the side of the indicator (for ITP11) or on the front panel (for ITP11-C). Users can set measurement range limits, scaling, units of measurement, damping, and alarm thresholds. The built-in diagnostic system monitors the indicator’s performance.

Advantages of Loop-Powered Indicators

• Easy installation – Compact and can be mounted close to sensors.
• Simple configuration – Parameters are set using an intuitive menu.
• Direct process monitoring – Provides real-time data access.
• Microprocessor-based control – Ensures high accuracy.
• Visualization capability – Suitable for process monitoring applications.

Limitations

• No communication interface – Cannot transmit data to external devices.
• Limited measurement type – Only measures current values.

Despite these limitations, loop-powered indicators like the ITP11 remain an essential tool for industries requiring accurate and reliable local measurement solutions.

How to Increase the Fault Tolerance of Utility Systems Without a Full Replacement of the Control System

During the winter season of 2024/2025, the issue of safe operation of heating and hot water systems became especially relevant. Ideally, safety requirements should be addressed at the design stage. However, there are often situations where a complete overhaul of the control system is not feasible, but improvements are still necessary. What can be done in such cases?

Modernizing Control Systems with Measuring Controllers

A partial upgrade can be implemented using industrial temperature controllers. These devices enhance the functionality of existing control systems by adding monitoring for pressure, temperature, and coolant flow in boiler rooms, heat distribution stations, and pump stations. This reduces the risk of ruptures, leaks, icing, and circulation stoppage.

This cost-effective solution can be easily integrated into an existing automation system:

• The price of an automation kit (including a sensor such as standard resistance thermometers from the DTS series or pressure sensors PD100 and a controller such as 2TCR1 does not exceed 200 EUR (including VAT).
• TCR controllers feature built-in logic for alarms, emergency shutdowns, sensor and actuator monitoring.
• Quick commissioning — only up to 10 parameters need to be configured.
• Universal input allows for pressure, temperature, or level control.

Example: TCP Controller Implementation

A heating circuit requires monitoring of critically low pressure with alerting and pump shutdown to avoid dry run damage.

By installing a 2TCR1 controller and a PD100 pressure sensor, the pump is automatically stopped when pressure drops below a safe level. Additional steps include installing the sensor using a medium separator, mounting the TCR unit, wiring the connection, and configuring the controller. If necessary, TCR can transmit the readings via a digital interface for dispatching.

Enhancing Control Systems with Remote Monitoring

Adding a dispatching system speeds up the response to abnormal events and improves situational awareness. To enable this, controllers must support digital communication interfaces.

In cases where the existing automation cannot transmit data digitally, consider upgrading key nodes as described earlier.

Modern trends show that classic SCADA-based dispatching is overly complex and redundant. For basic automation tasks, cloud monitoring services like acYtecCloud are sufficient.

Why this is convenient:

• No server required — data is accessible from any internet-connected device (with proper access rights).
• Data is securely stored in reliable data centers
• Free basic functionality is sufficient for monitoring systems like IHUs, CHPs, boiler rooms etc
• The cost of dispatching is within 100 EUR including the price of the Network Gateways and installation materials).

Example: Remote Alert Implementation

The objective is to notify the chief engineer via mobile phone in case of a critical pressure drop in the heating system. This enables prompt diagnosis and mitigation, preserving heat supply to residents.

Verify that the device monitoring the event can communicate digitally. Then, connect the GG-24-Cloud device (GSM, Wi-Fi, Ethernet), perform initial configuration via the cloud dashboard, and set up the alert (via Email or Telegram).

Use All the Functions of Industrial Controllers

Review the documentation for your installed automation equipment (including TCP controllers). You may find additional features that improve safety and reduce failure rates.

For example, alarm logic can be set on auxiliary outputs, or control circuits can be monitored to detect actuator issues early — valve faults, contactor failures, or stuck starters. Even basic TCR models support such features.

Unfortunately, these capabilities are often ignored during commissioning, as basic modes are considered sufficient.

Example: Zero-Cost Modernization

It is necessary to detect when a regulating valve fails to respond to control signals (LBA feature). This may indicate a broken communication line, faulty signal source, actuator issues, or mechanical jamming.

The controller can automatically detect this and raise an alert.

To enable this, turn on the LBA function and configure two parameters tailored to your application.

These are simple yet highly effective improvements from a cost-benefit perspective. By combining these approaches, utility companies can improve system reliability, prevent breakdowns, and minimize response time in emergencies.

2TCR1

PD100

In many industrial applications, thermocouples are used to measure temperatures in furnaces, pipelines, tanks, and other remote areas.

Traditionally, thermocouples are connected directly to controllers via expensive compensation cables. These are special alloy cables that are matched to the material of the thermocouple (e.g. NiCr/Ni for type K).

The longer the cable run, the higher the cost. For distances over 50–100 metres, cable costs can account for a significant proportion of the project budget.

What is NPT3?

The NPT3 is a signal conditioning transmitter that is built directly into the head of a DIN-standard thermocouple sensor. It:

• Receives the millivolt signal from the thermocouple
• Converts it into a standardized 4–20 mA current signal
• Transmits the signal to the controller using a regular shielded cable

What are the benefits?

1. No need for compensation cables (types K, J, S, etc.), which typically cost €3–€6 per meter.
2. Standard shielded copper signal cables (e.g., LiYCY 2×0.5 mm²) starting at €0.8 per meter can be used instead.
3. NPT3 eliminates the negative effects of cable length and ambient temperature on measurement accuracy.
4. Signal cable lengths of up to 500 meters or more can be used—without any loss of signal quality.

Example: Cost Comparison

Scenario 1

Scenario 2

Let us imagine that we need to connect a thermocouple at a distance of 100 meters to the controller:

Savings: €350. The farther the thermocouple is from the controller, the greater the savings.

Additional Savings: On Controllers Too

Using the NPT3 not only reduces cable costs, but also controller expenses.

Controllers that connect directly to thermistors (e.g., Pt100) are typically more expensive due to specialized input circuitry and wire resistance compensation.

By contrast, controllers that accept 4–20 mA signals are widely available, standardized, and generally much more affordable.

With NPT3, you can opt for a simpler, cheaper controller without compromising performance.

Note: akYtec controllers are universal and support thermocouples, RTDs, voltage (0–10 V), and current (4–20 mA) signals.

NPT3: Not Just About Cost

You also get:

• Strong resistance to electrical interference (via 4–20 mA signal)
• Improved measurement accuracy
• Simplified wiring and maintenance
• Compatibility with any controller

Unmanaged network switch

In today's world, where there are many factors beyond our control, such as weather and climate changes, human error, technical failures such as power outages, ventilation failure, faulty safety sensors. There is a need for clarity and certainty in most areas of personal and professional activities. Building Management Systems (BMS - Building Management System) come to your aid in the field of building management, which allow you to centrally monitor, control and optimize the operation of engineering systems.

So what is a BMS?

BMS (Building Management System) is an intelligent, automated building management system that integrates and controls all of a facility's utility systems. It includes control of heating, ventilation, air conditioning (HVAC), lighting, energy consumption, security and other critical functions.

The primary objective of a BMS is to optimize building performance by reducing operating costs, increasing energy efficiency, and providing a comfortable environment for users. Without an intelligent control system, a building is forced to “exist blind”, wasting energy, resources and ultimately profit. But with a BMS, it becomes efficient, reliable and resilient, like a healthy and well-functioning organism.

Did you know that over the 40-year lifecycle of a building, about 50% of all costs are attributed to building maintenance? Research by Building Management System Market by Software from Markets and Markets shows that facilities that have implemented a BMS system and use utility dispatch (shopping centers, office buildings and other large complexes) reduce maintenance costs by an average of 5-30% per year. And for some industrial buildings, where proper energy distribution is the most important condition for operation, the savings can be up to 50%! These include data centers, airports and hospitals.

According to the Building Automation Systems Market Size & Share Analysis - Growth Trends & Forecasts (2025 - 2030) report by Mordor Intelligence, the global building automation systems market size was valued at USD 201.08 billion in 2024 and is projected to reach USD 332.01 billion by 2029, exhibiting a compound annual growth rate (CAGR) of 10.55% from 2024 to 2029. And it's not hard to calculate how much companies are potentially losing due to inefficient building management! These amounts could be as much as 100 billion US dollars. It becomes clear that BMS is only gaining momentum and now is the time to start working in this advanced field or implement BMS systems in your company. According to the same report, the average return on investment (ROI) from implementing integrated BMS systems in a building is 3-8 years, which is a very good indicator in our industry. BMS covers a wide range of building processes, Here are some examples of what the BMS controls:

• Energy Management
• Heating, Ventilation and Air Conditioning
• Lighting Control
• Security & Access Control
• Water Management
• Occupant Comfort
• Smoke Control and Fire Safety System

BMS makes a building smart and energy efficient, ensuring safety, comfort and reduced operating costs. The integration of all these systems into a single platform allows you to manage the facility in real time and prevent critical failures.

Building Management System (BMS) is a multi-level structure that combines various devices and software solutions for centralized control of engineering systems. In general, its structure is similar to the classic enterprise automation system you are all familiar with, and it is. It also consists of three levels and uses the same devices as other systems. But in its essence BMS considers all these three levels as one system and there is no strict division between the levels, it focuses strictly on complex building management, not focusing on any one process or parameter. And also BMS systems include design and consulting services.

Our company specializes in the Automation level of BMS, ensuring reliable communication between sensors, actuators and the central control system. And here we recommend using PR103 - controller with Ethernet, which is suitable for work with BMS. And also try our new service for remote monitoring and control of industrial devices - akYtec Cloud!

Why is PR103 our recommendation for BMS operation?

• Availability of RS-485 for field level operation - easily integrates with various sensors and actuators via Modbus RTU protocol.
• Ethernet for transmitting processed signals to a central controller - provides reliable communication to a controller further down in the system.
• Support for all types of inputs and outputs (DI, FDI, DO, AI, AO) - the versatility of the PR103 allows a wide range of sensors and actuators to be connected without additional transducers.

General advantages of a BMS system using PR103 and akYtec Cloud

By utilizing local controllers at each BMS node, our system offers a number of key benefits:

• Resilience at every level - even in the event of a communication failure or main controller failure, the nodes continue to operate autonomously.
• Reduced load on the central server - if the BMS system serves a large facility, the distributed structure reduces the computational load on the main controller, improving speed and stability.
• Cloud integration - With akYtec Cloud, building management becomes even more convenient. This feature is especially useful for service companies that maintain buildings and manage multiple facilities. Now you can control all facilities remotely, respond quickly to problems and optimize maintenance costs.
• System Expandability - If you need to expand your system, the PR103 can be easily connected to 2 PRM modules via the internal bus without any loss of performance. And the availability of 2xRS485 makes it possible to connect additional external modules.

Using PR103 and akYtec Cloud as part of a BMS allows you to increase the reliability and efficiency of building management, reduce operating costs and create a flexible, scalable system ready for any task.

Implementing a BMS can significantly improve the efficiency of building management, reducing operating costs and providing a comfortable environment for users. The use of local controllers, such as PR103, contributes to the flexibility and autonomy of the system, minimizing the risk of failures and reducing the load on the central controller. Additionally, integration with akYtec Cloud simplifies data monitoring and analysis. Thus, a complete BMS solution using PR103 and akYtec Cloud ensures reliability, energy efficiency and sustainability in building management.

akYtec developed a control system for a client's site, which manages water levels in tanks and includes remote control of a deep well valves with online water meter readings. The main control offers manual and automatic modes based on water levels. This system improved efficiency, reduced labor costs, and provided real-time monitoring with SCADA system and control capabilities.

From akYtec's range, we utilized the following components:

• PR103
• SMI200
• PD100 (pressure)
• PASF-60.24

Additional elements included:

• Button
• Level sensor
• Alarm siren
• Light
• Valves
• SCADA system

Controller I/O Terminal Assignments:

• I1: Connection for the external button to start manual mode.
• AI1: Level sensor.
• AI2: Pressure sensor on input.
• AI3: Pressure sensor on output.

• Q1: Manual mode selected, LED.
• Q2: Automatic mode selected, LED.
• Q5: Input pressure out of range.
• Q6: Alarm.
• Q7: Output pressure too high.

• AO1: Input valve.
• AO2: Output valve.

This PLC program manages a water system by switching between manual and automatic modes (Q1) to control water levels and pressures. It uses sensors to monitor these parameters (AI 1…3) and adjusts valves accordingly (AO 1 and 2) to maintain optimal conditions.

Alarms are set to alert (Q 5…7) if pressures exceed safe ranges, ensuring efficient and safe operation of the water system. The program is designed for real-time monitoring and control, enhancing system reliability and responsiveness.

Yellow section : Is meant for mode selection indication. When user activates manual mode (Variable “Mode switch” =1), “Automatic mode active” LED turns OFF (Variable “Automatic mode active”=0) and “Manual mode active” LED starts blinking ( Variable “Manual mode active”) indicating that system is manually controlled.

Orange section: Is for setpoint selection. If system is in automatic mode, then water level setpoint is predefined, but if user activates manual mode system will target “Manual setpoint” value, which is set over SMI200.

Red section: Is for indicating (over signal lamps) and alarming (over siren) if any pressure of input/output valves is out of range. Tripping setpoints are defined inside ALP and can not be modified by user for safety purpose.

In addition, ALARM signals are collected and sent to the SCADA system through Ethernet which was the key request from the user.

Green and Blue sections: Here PID blocks can be found, which are responsible for stable control of input/output valves for water filling. PID inside green block is controlling input valve (trying to reach water level setpoint), while the PID inside blue section is controlling output valve (trying to reach lower setpoint). This way, system always has water deposit in the tank, while ensuring constant water flow through output pipe.

This project involves the development of a control system designed to manage water levels in tanks using mini PLC technology. The control system includes remote control of deep well valves and provides real-time water meter readings. The system operates in both manual and automatic modes, enhancing efficiency, reducing labor costs, and providing real-time monitoring and control capabilities through a SCADA system. The control system features a water tank, pressure sensors, pipes, valves, a control block with PR103 as the main part, and a water level sensor.

The PR103 controls the overall operation, supported by the SMI200 for manual setpoint adjustments and PD100 pressure sensors for monitoring input and output pressures. The PASF-60.24 provides necessary power supply.

The system diagram illustrates various sections. The Mode Selection section includes a manual mode activated LED and an automatic mode active LED. The mode switch toggles between manual and automatic modes, with the manual mode LED blinking when active and the automatic mode LED turning on during automatic operation.

In the Setpoint section, water level setpoints can be defined. In automatic mode, the setpoint is predefined, whereas in manual mode, it targets a user-defined manual setpoint adjustable via the SMI200. The Alarm section is designed to indicate and trigger alarms if input or output pressures exceed safe ranges. It includes indicators for when the pressure is too high or when the input pressure is out of range. These alarms are also sent to the SCADA system via Ethernet for real-time monitoring and alerts, which was the key request from the client, thus PR103 was the only logical choice.

Input and Output Control sections use PID controllers to manage the input and output valves. The input control PID maintains the water level at the setpoint, while the output control PID ensures a constant water flow through the output pipe, maintaining a lower setpoint. This setup ensures a stable water deposit in the tank while providing consistent water flow.

The control system's software manages the water system by switching between manual and automatic modes, using sensors to monitor water levels and pressures. The sensors connected to the system include a level sensor for water level detection, a pressure sensor on the input pipe, and a pressure sensor on the output pipe. These sensors provide real-time data to the PLC, which adjusts the valves to maintain optimal conditions and sets alarms if pressures exceed safe limits.

Manual mode can be activated via an external button, and the system will display the current mode using LEDs. The manual mode LED blinks when manual mode is active, and the automatic mode LED illuminates when the system is in automatic mode. Alarms are crucial for safe operation, and the system includes several alarms for various conditions. If the input pressure is out of range or if the output pressure is too high, the system triggers alarms and activates the corresponding LEDs. The system also sends these alarm signals to the SCADA system for immediate action and monitoring.

The inclusion of analog outputs, with their programmability as their key property, in this device enables the control of various components such as valves, enhancing the system's versatility and functionality. Additionally, the use of universal analog inputs in the PR103 allows for the connection of a wide range of sensors, making the circuit adaptable to various sensing requirements.

Overall, this real-time monitoring and control system enhances reliability and responsiveness, ensuring efficient and safe operation. By providing a comprehensive solution for water level management, this PLC-based control system significantly improves operational efficiency and safety.

Hello! This is the second article in the "What to Choose?" series. Today, we will discuss what a temperature transmitter is, why it is needed, and when it is more convenient to use modules with universal analog inputs instead of a temperature transmitter. We will explore the advantages and disadvantages of each option, as well as their applications in centralized and decentralized systems.

What is a temperature transmitter and why is it needed?

Temperature transmitters are designed to convert resistance temperature detector (RTD) and thermocouple (TC) signals into unified current (4-20 mA) or voltage (0(1)-10 VDC) signals. Signal unification allows to reduce the cost of special cables for thermocouples, eliminate the influence of electromagnetic interference, simplify the connection of sensors to PLC, increase the length of communication between the sensor and the measuring device.

1. To connect thermocouples to measuring devices and ensure measurement accuracy, special cables are used, which are made of the same alloys as the thermocouples themselves, e.g. types K, J, T and etc.. They are considerably more expensive than ordinary copper cables used for 4-20 mA or 0-10 V communication lines.
2. The non-normalized signal at the RTD or TC output is subject to various interferences that introduce errors into the process. Temperature transmitter filters out the interference. Standard filtered signals provide more accurate and stable data, which is critical for important process applications.

DEVICE	TYPE OF OUTPUT SIGNAL	SIGNAL APPEARANCE
Temperature transmitter	4-20 mA or 0-10 VDC
TC or RTD	Ω, mV

3. Not all PLCs and I/O modules support direct TC or RTD connection, but almost all devices support standard 4-20 mA or 0-10 V signals.
4. Thermocouples and RTDs have limitations on the length of the communication line (TC up to 20 meters, RTD up to 100 meters). The use of temperature transmitter allows to increase the communication length up to 800 meters.

There are two modifications of temperature transmitters in akYtec catalogue: NPT3 and NPT4. The main difference between these devices is the mounting option: NPT3 is mounted inside the sensor with special enclosure, while NPT4 is mounted on a DIN rail in the cabinet. In situations where the sensor is exposed to extreme temperatures, it is better to use the remote NPT4, as the NPT3 has a limited operating temperature range (-40...+85 °C).

DEVICE	ELECTRICAL CONNECTIONS

NPT4

Having learnt the peculiarities of the temperature transmitter, let's move on to the second part of our article.

I/O MODULES vs TEMPERATURE TRANSMITTER

Consider a situation where there are a large number of sensors (50-100 or more) spread over different locations in a production facility. Installing a PLC at each location is too costly and inefficient, and running communication lines a long distance from each sensor to a central PLC increases data errors due to interference.

Is it convenient to use temperature transmitters in this situation? Is there a way to avoid running a cable to the PLC from each sensor?

This problem can be solved by using remote input modules with universal analogue inputs, placed near the sensor group.

Using akYtec modules with universal analogue inputs will simplify the automation system, make it more flexible and scalable, reduce cabling costs and eliminate the need for temperature transmitters.

The akYtec I/O modules are categorized into two series Mx110 with RS485 and Mx210 with Ethernet. In each series there are modules with universal analogue inputs: MV110-24.8A and MV210-101, to which up to eight TCs or RTDs can be connected directly.

DEVICE	INTERFACE & PROTOCOLS	SPEED	DISTANCE	SIGNAL TYPE
MV110-24.8A	RS485 Modbus RTU, ASCII	Up to 115200 bit/s	Up to 1200 m	RTD, TC, 0-5 mA, 0(4)-20 mA, 0-1 V, 0…(2)5 kOhm, switch contacts
MV210-101	Ethernet Modbus TCP, MQTT, SNMP	Up to 100 Mbit/s	Up to 100 m per segment	RTD, TC, 0-5 mA, 0(4)-20 mA, 0-1 V, 25…900(2000) Ohm, switch contacts

Comparison of main parameters of modules and temperature transmitter

Conclusion

The choice between the devices in this article will depend on the requirements and scale of your automation system.

The Mx110 and Mx210 modules are ideal for complex, multi-sensor environments requiring advanced communication and data logging. They offer versatility, scalability and high accuracy, although they can be more complex to set up.

Temperature Transmitters are better suited for simple applications with a small number of sensors where ease of use, low cost and compact size are important. Transmitters provide reliable and simple conversion of sensor signals to standard analogue signals.

We’re glad to see you again in our account! We prepared a new video about programming PR as slave and connecting the SMI200 operator panel as master and it’s already on our channel. The video includes PR100, PR102, and the upcoming PR103. For our example, we’ll use PR102, as it is the most popular model.

Let's define our task for this video: Suppose we have an actuator connected to the discrete output of the PR, and I want to turn it on and off using two buttons connected to the inputs of the same PR, as well as using elements on the operator panel screen.

We will create two projects: one for the PR, another for the SMI200, and connect them via the RS-485 interface. Get started with us!

When selecting discrete output modules, it's important to consider their type, characteristics, and applications. akYtec offers modules with various types of discrete outputs: electromagnetic relays, PNP, and Push-Pull. Each type has its advantages, disadvantages, and specific applications. Let's take a closer look at each of them.

Differences between PNP, Push-Pull and Relay Outputs

PNP Outputs PNP outputs, also known as "high-side" outputs, work as follows: when a low logical signal (logical 0) is applied to the base of a PNP transistor, the transistor switches on and supplies power to the load connected to the collector. This means PNP outputs "push" current to the load. In these circuits, the load is connected between the output and ground.

PNP outputs are common in industrial automation and are often used in systems where devices are powered from a single DC source.

Fig. 1 Wiring of a high-side output

Push-Pull Outputs Push-Pull outputs use both PNP and NPN transistors. In this configuration, one transistor "pushes" current to the load, while the other "pulls" current from the load to ground. As a result, Push-Pull outputs can both supply power to and draw power from the load, making them more versatile.

In Push-Pull configurations, the load is connected between the outputs of two transistors, allowing these circuits to provide bidirectional current control. This is especially useful in applications where rapid changes in current direction are required.

Fig. 2 Wiring of a push-pull output

Relay Outputs Relay outputs use electromechanical relays to control loads. Relays are devices that can open or close contacts under the influence of a control signal, allowing relay outputs to control both small and large loads.

Fig. 3 Wiring of relayl output

Advantages and Disadvantages

Advantages of PNP Outputs

1. PNP outputs are easy to integrate into systems requiring simple load control.
2. Widely used in the industry and compatible with many types of loads.
3. Simple circuits reduce the likelihood of failures and simplify diagnostics.

Disadvantages of PNP Outputs

1. PNP outputs can only supply current to the load, limiting their application.
2. In industrial environments, PNP outputs may be sensitive to electromagnetic interference.
3. Like Push-Pull transistors, PNP outputs have limitations in current and voltage.

Advantages of Push-Pull Outputs

1. Can both supply and draw current, allowing for more complex tasks.
2. Push-Pull outputs provide quick response times, crucial for high-frequency switching applications.
3. The differential nature of the signals helps reduce the impact of electromagnetic interference.
4. Have a wide range of applications, from motor control to precise actuator control.

Disadvantages of Push-Pull Outputs

1. Like PNP transistors, Push-Pull outputs have limitations in current and voltage.

Advantages of Relay Outputs

1. Relay outputs can control high-voltage and high-current loads, making them versatile.
2. Relays provide electrical isolation between control and controlled circuits, protecting electronics from high voltages and interference.
3. Relay outputs are often used in high-temperature or vibration-prone environments, where semiconductor devices may be less reliable.

Disadvantages of Relay Outputs

1. Relay outputs have significant inertia and can be slow compared to semiconductor devices.
2. Relays require more space and can be heavy, especially for high-power applications.
3. Limited number of switching operations

akYtec Discrete Output Modules

In the akYtec catalog, you can find several types of discrete output modules, each with unique characteristics and designed to solve specific tasks:

• MU210-401, MU210-402, MU210-403: Modules with relay outputs.
• MU210-412: Module with Push-Pull (DO1…8) and PNP (DO9…DO24) outputs.

Conclusion

When choosing a discrete output module from akYtec, it's essential to consider the type of outputs, their number, the presence of galvanic isolation, and operating modes. Depending on your requirements for switching speed, switching capability, and specific application conditions, you can select the most suitable module from the company's range.

Welcome back to our channel! Watch a video about the Modbus master on our YouTube. We will talk about querying other devices, making it a network master.

In this video we will connect a temperature sensor PT1000 to its first input, and we’ll display its readings on the PR screen. The interface we will use to connect the PR and the input module is called RS-485. This is a serial interface, which means that the devices you connect with it should be connected to each other in sequence, one after the other.

1. Pre-requirements

For physical connection, you will need a micro USB.

Tool PRO can be found on our website.

2. Connecting Mx210 with Tool PRO over micro USB

Open Tool PRO on your PC.

Connect the micro USB to Mx210 and the other side of the cable to your PC. Then, click in Tool PRO’s window on "Add device," as shown in Picture 2.1.

Picture 2.1

Now, in the new window, configure Network parameters as shown in Picture 2.2.

Picture 2.2

As you can see, the first parameter is Interface. Since we are using micro USB, select COM (in our situation it is numbered as 6, but it can be any number). Other parameters are for the automation of device detection, so set them as shown in Picture 2.2. However, the last one "Find device-Address" is a bit different. First, insert number 1 into "Address" (it is factory default and cannot be changed) and then click on "Find". If the device couldn’t be found, then select "Find all devices" and fill in the next two cells as shown in Picture 2.2.

If the device was successfully detected, it will appear on the list as shown in Picture 2.3. Then, check the box and click "Add devices."

Picture 2.3

If there is no table with cells after you have clicked on "Add devices," try and click on "Read parameters," as shown in Picture 2.4.

Picture 2.4

3. Connecting Mx210 with Tool PRO over Ethernet

For this, along with what is mentioned in the pre-requirements section, you need the IP address and Subnet mask of your Mx210. The factory-set IP address is written on the side of the device (in our case it is 192.168.1.99 and the mask is 255.255.0.0. The mask is not written on the device but the mentioned one is the default). However, if you don’t manage to connect to the device with the factory-set IP address in the following steps, that means that the IP address has been changed in the past (as it is in our case; notice that the last digit of the IP is 15)./p>

Now, follow all steps from section 2 of this document (at the end you will have the IP address of the device) and read the network parameters.

Go to the network settings of your PC, double-click on the Ethernet port, select IPv4, and click on properties; it will look like Picture 3.1.

Picture 3.1

In the last window, select “Use the following IP address” and then insert the IP address and Subnet mask of your Mx210. The last number of the IP address has to be changed because now we are configuring our PC to communicate with the Mx210. You can put any number from 1 to 255.

Picture 3.2

Now click OK on this window and on the “Ethernet properties” window.

Connect the Ethernet cable to Mx210 and the other side of the cable to your PC. Then click in Tool PRO’s window on "Add device," as shown in Picture 2.1.

Picture 3.3

Now, in the new window, configure Network parameters as shown in Picture 3.4.

Picture 3.4

4. Configuring Mx210

For setting up communication between Mx210 and, for example, our PR103, it is important to configure parts of Network-Ethernet as shown in Picture 4.1.

Picture 4.1

Now you need to change all of these parameters according to the ones on PR103 (or another device you are going to connect Mx210 to), or type these existing parameters into PR103. If you don’t know the addresses of registers that you will use to transfer data from Mx210, click on "Parameter list", as shown in Picture 4.2.

Picture 4.2

5. What to do if IP address or Password is forgotten

In case of a forgotten IP address, use a micro USB cable and follow sections 2 and 4 of this document to retrieve the IP address. If the password has been forgotten, power ON the device, open the front cover, and then press and hold the Service button for at least 12 seconds. The location of the Service button is shown and marked with number 7 in Picture 5.1.

Picture 5.1

6. Factory settings

If you desire to bring Mx210 to factory settings, go to Tool PRO (follow section 2 of this document) and when you successfully read the parameters of the device, click "Factory settings" and then click on "Write parameters" as shown in Picture 6.1.

Picture 6.1

7. Configuring network settings of multiple Mx210 modules at same time

Note :

The following steps will be taken in such a way that this explanation and configuration ends up as simple as possible, so experienced users can take different steps.

The pre-requirement is an Ethernet cable for each Mx210.

If you want to configure network settings of multiple Mx210 modules, first configure your PC’s network settings as shown in section 3. Because the default IP address of devices is 192.168.1.99 (even if it was changed in the past, it probably starts with 192.168.X.X), set your PC’s address as you will (here we will set it as 192.168.1.10, as shown in Picture 3.2).

Connect Ethernet to the first Mx210 (Ethernet 1 port) and to the PC, then connect all other devices with an Ethernet cable (example: First Mx210’s Ethernet 2 port connects to Second Mx210’s Ethernet 1 port, and so on). Open Tool PRO, and click on "IP addresses", as shown in Picture 7.1.

Picture 7.1

On the left side of the newly opened window, you can see the section New IP address. Modify the last two numbers at your will of the IP address that is already inserted (in our case it is 192.168.1.11, because it will increase your PC’s IP address by 1). Our recommendation is to change only the last number (in the range 1-255, but choose a number that is bigger than the PC’s number).

Now, the Service button (shown in Picture 5.1) should be clicked on each device, in the order in which you want to spread IP addresses. After each successfully set IP address, the next one will be automatically increased by 1. At the end, it should look like Picture 7.2.

Picture 7.2

Now click on "Add devices" and that would be it.

Project Overview:

akYtec's engineering team has successfully completed a project for a client managing a dairy farm. The client sought to collect data from standalone structures, specifically cow shelters, to ensure optimal living conditions for the livestock. The main problems faced by engineers were limited budgets and the inability to lay cables between buildings. To achieve this, we utilized a beta version of akYtec Cloud, in conjunction with our sensors and I/O modules.

System Description:

Each standalone building is equipped with a dispatching panel that houses Mx210 modules and a network gateway. The building's engineering system parameters are monitored by input/output modules featuring Ethernet Bypass technology. This technology ensures continuous data transmission between modules in the event of a module failure. The parameters monitored include:

• Water temperature and pressure in the supply system.
• Air temperature and humidity within the shelter.
• Status of engineering systems, including signals from gas analyzers.
• Position of automatic circuit breakers and backup supply parameters.

Data collected by the input/output modules is transmitted to akYtec Cloud via gateways.

The system is engineered to automatically maintain the desired temperature in the pool. Each night, leveraging periods of lower electricity costs, it initiates water filtration and heats the pool water.

From akYtec's range, we utilized the following components:

• PR100 MINI PLC
• DTS125L PT100 / PT1000
• SMI2-M
• PASF-60.24

Additional elements included:

• Water pumps
• Heat pump
• Water filters
• Reset button
• Signal lamp

Controller I/O Terminal Assignments:

• I1: Connection for the external button to reset the heat pump logic.
• AI1: Input for Temperature Sensor 1 (at the heat pump's intake).
• AI2: Input for Temperature Sensor 2 (at the heat pump's output).

• Q1: Output controlling Water Pump 1.
• Q2: Output controlling Water Pump 2.
• Q3: Output controlling the Heat Pump.
• Q4: Output for the External LED Indicator.

Input Variables:

• Temperature Sensor 1: Holds the water temperature value at the heat pump's input side.
• Temperature Sensor 2: Holds the water temperature value at the heat pump's output side.
• Temperature - External display: Holds the water temperature value at the heat pump's output side.
• Reset the Heat Pump: Stores a value of 1 or 0, depending on whether the reset button is pressed.

Changeable Parameters:

• Schedule: The CLOCK1 block holds the schedule, which is adjustable.
• Warmup Time: The TON1 block (inside the yellow area) specifies the duration allotted to the heat pump before the safety-check "protocol" activates.
• Warmup Time: Positioned in the top-left section of the diagram.

Full technical description of the project

The CLOCK1 block (represented in green) triggers Pump 1 and Pump 2 to operate according to the predetermined schedule. Subsequently, the program (indicated by an orange) evaluates if the "Temperature Sensor 1" variable is below 29 degrees (the desired water temperature, set within a red). If so, the heat pump is engaged.

Concurrently, as soon as the "Heat Pump" variable attains a value of 1, the safety-check "protocol" initiates (highlighted in yellow).

The safety-check "protocol" initially grants the heat pump a 10-minute period to reach its "working condition." Following this interval, the protocol compares the difference between the "Temperature Sensor 2" and "Temperature Sensor 1" variables. If the difference exceeds 2 degrees, the system is deemed operational. Conversely, if the difference is less or equal to 2, the heat pump is "blocked," and the external LED indicator begins to blink (depicted in purple).

To reset the PLC logic and render the system operational after addressing any issues with the heat pump, it's necessary to press the "Reset Heat Pump Button".

With our PLC-based control system, you can effortlessly enjoy the optimal pool environment. The akYtec PR100 MINI PLC, paired with the Akytec DTS125L PT100 / PT1000 temperature sensor, guarantees precise temperature measurements, ensuring your pool is consistently maintained at your preferred comfort level.

Our system's automated features offer:

Seamless Temperature Control: The akYtec PR100 and DTS125L PT100 tirelessly work 24/7 to maintain your water at the ideal temperature. Whether you're looking to cool off on a scorching day or enjoy a warm swim on a chilly evening, your pool will always be ready to welcome you.

Energy Savings: Benefit from our intelligent system that smartly adjusts heating and filtration times, significantly cutting down on energy consumption without compromising the pool's quality.

Prolonged Equipment Life: Our system's accurate and consistent control minimizes stress on your pool's equipment, prolonging the lifespan of your investment and ensuring lasting enjoyment of your pool.

We prepared a new video about the triggers for you and it’s already on our channel. It’s a bit complicated, but with our explanation you will understand everything for sure.

Triggers or Bistable blocks are RS and SR elements. They are used to separate the logic of turning a device ON from the logic of turning it OFF. These blocks have two inputs: 'Set' - "S'' and 'Reset' - 'R'. The first one generates a command to turn on the output, and the second one turns it off. And the output operates according to the last command given. There are also a couple other elements from the library: D-trigger, RTRIG and FTRIG.

The automation system is decentralized and built according to the modular principle. Each unit of process equipment has its own independent automation cabinet based on programmable relay akYtec PR100. More than 40 cabinets are distributed on the territory of the object and are located in close proximity to the controlled equipment. At such construction of system, due to reduction of quantity of cable and wiring products, the budget of project realization is reduced by more than 30%. In addition, the reliability and maintainability of the automation system increases.

Maintenance personnel, even in the absence of experience in the operation of this object, easily finds faults, because it is necessary to deal not with a large cabinet of the centralized system with a huge number of inputs / outputs, and with a fairly primitive panel of local automation. In case of failure of akYtec PR100 (which did not happen for 2 years of operation) flashing of the backup (and installing it in the cabinet) takes no more than 15-20 minutes.

For centralization of the complex control, construction of grain transshipment routes and ensuring mutual interlocking of technological equipment technological equipment, all cabinets are interconnected via RS485 interface, and in the control room there is a touch screen operator panel. operator's touch panel.

Initially, the project envisioned the use of a conventional PLC to control a network of cabinets with akYtec PR100, but writing macros for the operator panel allowed to overlap the functionality assigned to the PLC and abandon its use.

The system is designed to control parking entry/exit, while monitoring the amount of left parking spots.

We used from the akYtec's offer :

• PR100 MINI-PLC
• PASF-60.24

Other elements:

• Ramps
• Ticket printer
• Infrared sensor
• Display for number of empty parking
• Green button
• Ticket scanner

Body of the program in the akYtec ALP

Designation of the Controller I/O Terminals:

• I1: Enter button
• I2: IR-sensor 1
• I3: Ticket scanner
• I4: IR-sensor 2

• Q1: Ramp 1 (entry ramp)
• Q2: Ramp 2 (exit ramp)
• Q3: Ticket printer

Input variables:

• Enter button (gets value 1 when someone press button)
• IR-sensor 1 ( gets value 1 when triggered ( entry sensor))
• IR-sensor 2 ( gets value 1 when triggered ( exit sensor))
• Ticket scanner ( gets value 1 when you scan paid ticket , otherwise 0 )

Output variables:

• Ramp 1 ( gets value 1 when you want to open ramp)
• Ramp 2 ( gets value 1 when you want to open ramp)
• Ticket printer ( gets value 1 when someone press button and there is empty parking spots)
• Empty slots ( network variable for external display)

Full technical description of the project

Note: Ticket scanner, ticket printer and external display are not our products, so this is a theoretical solution. Real solutions will vary depending on actual devices used in the project.

In the yellow box you should set number of spots your parking has.

In the blue box is a counter (CTN1) which monitors the number of cars in parking. Total parking slots will be compared with the number of cars in parking and if there are empty slots, the value of variable “you can park” will be set to 1.

In the green box is logic for entering parking. Firstly system waits for “enter button” to be pressed and if that happens ( and if there is empty parking spots) system is triggered, meaning :

• your parking ticket will be printed
• Ramp 1 is opened
• And you have 15 second to go through the ramp

If you don't go through the ramp in 15 seconds, the ramp will start to close (this process will take 5 seconds to complete). If you, in those 5 seconds, cross over IR-sensor the ramp will open and allow only 1 (your car) to go into parking, meaning any other car behind you will not make the ramp open again.

In the pink box is logic for exiting parking. Firstly the system waits for a paid ticket to be scanned and if that happens the system is triggered (procedure is identical to enter logic).

In the light red box is network variable “empty slots” which is used to talk to the external display.

Hello friends! The video about “the Selector” is finally out, we’ve been carefully preparing it for you so that such an important video would be as interesting and educational for our viewers as possible.

The selector is, in essence, like an “if-else” conditional construction, but only for the functional block language. In the latest version of the ALP component library, you'll find two such elements - one for working with integer data, and the other for real numbers. From the video you will learn everything about the selector and its applications.

The best part about these features is that you can use them for different interesting things such as smoothly increasing the value of the setpoint when holding the down button Or recalculating the value of the setpoint by some formula by command when it is not necessary for it to be constantly updated.

Alright, enough words, hurry up and watch the new video and expand your knowledge about the ALP component library!

In their work, specialists of the I&C department often perform various tasks on maintenance of process equipment, various preventive maintenance and, of course, modernization of control systems.

A pumping equipment control system was created to provide water supply to production shops and office premises. Water from an artesian well is supplied to two storage and communicating tanks, and is pumped through a pipeline into the internal network by means of a water supply pump.

The supply pump is equipped with an automatic system that monitors the pressure in the system and shuts it off if the pressure (6 bar) is exceeded. The pump, pumping water, with a capacity of 180 l/min fills a storage tank of 5,000 liters, this water goes to the production of vinegar and bottling of water. Backup pump provides independent operation of the water supply system. If the working pump fails, it is disconnected from the system and the standby pump is activated.

The akYtec PD100 pressure transmitter is designed to monitor system pressure effectively. It is a specialized pressure transmitter ideal for HVAC systems, pumps, compressors, boilers, and water supply systems. Utilizing diffused silicon sensors, the PD100 offers superior sensitivity and accuracy compared to other sensor technologies, ensuring precise pressure measurement for various applications.

The akYtec 2TRM1 single-channel controller regulates and displays the current pressure. A low level sensor acts as dry run protection.

The system utilizes three non-contact capacitive sensors that are mounted on the tanks. When the water level drops below the set level, the pump automatically switches on and runs until the water level reaches the upper level. When the emergency level sensor is activated, the pump is switched off and the alarm is indicated.

Selection of programmable relay mini-PLC akYtecPR100 can easily handle the tasks of supplying, pumping and monitoring of pumping equipment. The AkYtec ALP 2.2 environment was used to program the PR100.

Pump control algorithms are presented in the form of corresponding macros, which are created in the main window. In this project the following signals are controlled:

• I1: lower level of water intake (dry run protection of the pump);
• I2: pressure level reached signal (2TRM1);
• I3: water supply switch;
• I4: pump thermal protection (pump fault signal);

• Q1: pump start outputs
• Q2: EMERGENCY indicator

Accordingly, a macro with three inputs and two outputs is created. The correctness of the program operation can be checked with the help of the built-in simulator at the development stage and to identify any errors.

Programmable relay replaces bulky relay circuits, significantly reducing maintenance costs, as it allows you to change the algorithm of operation, if necessary, to adapt local control systems.

PR100 is one of the most budget-friendly devices on the market, which distinguishes it from its analogs.

And one more important factor for PR100 programming is that it is not necessary to have special skills of programmer and circuit designer.

If you're in the market for input/output modules for your distributed automation systems, akYtec's MX110 series offers a reliable and cost-effective solution. These modules are suitable for decentralized data acquisition and process control, providing a practical supplement to existing systems or the foundation for new setups.

Here's how to pick the right one.

Analyze System Needs:

Evaluate the number and type of input and output points your system requires. MX110 modules come in digital and analog variants to accommodate various signal types.

Digital vs. Analog:

Choose digital modules for simple on/off signals and analog modules for variable signal sensors. Fast analog inputs are available for applications needing rapid processing.

System Compatibility:

Ensure that the MX110 modules are compatible with your existing SCADA system, HMI, or PLC, specifically supporting the RS485 interface and Modbus RTU/ASCII communication protocols.

Advanced Features:

For more than basic data acquisition, opt for modules with pulse counters, sensor state diagnosis, PWM on digital outputs, additional logic functions, transmission protocol auto-detection, and fail-safe features to enhance system resilience.

By following these guidelines, you can ensure you select the MX110 module that best fits your automation requirements, delivering reliability and flexibility to your system.

For example, if you are in the fish industry, working at a fish processing factory, you probably have a large fridge hall where you need to control several parameters in a decentralized system:

• The condition of the tile freezers (freezing, defrosting, or stopping);
• The condition of the refrigerant circulation pumps (operation, accident, or shutdown);
• The current level value in the circulation receiver;
• The upper emergency level in the circulation receiver;
• Status of the refrigerant level sensor in the circulation receiver;
• The current value of the suction and discharge pressure of the units;
• Compressor status (operation, compressor blocking stopped);
• Compressor performance (50, 75, 100%);
• The status of the condenser fan groups (operation or shutdown).

In general, you’ll have around 45-48 digital signals you need to acquire and send to your PLC. To cover this case, you’ll need to organize 3 control cabinets: the first one will manage the control of the freezers' solenoids, the second will be responsible for condensate management, and the third will control the circulation receiver. To manage it, you can just place our digital input module MV110-24.16DN in every control cabinet, ensuring all signals are acquired and successfully transferred to the PLC.

For any of your applications, you can select modules according to these tables:

MV110 DIGITAL INPUT MODULES (DI, MODBUS RTU/ASCII, RS485)

MV110 ANALOG INPUT MODULES (AI, MODBUS RTU/ASCII, RS485)

MU110 DIGITAL OUTPUT MODULES (DO, MODBUS RTU/ASCII, RS485)

MU110 ANALOG OUTPUT MODULES (AO, MODBUS RTU/ASCII, RS485)

MK110 INPUT AND OUTPUT MODULES (DI/O, MODBUS RTU/ASCII, RS485)

Body of the program in the akYtec ALP

Designation of the Controller I/O Terminals:

• I1: Dry running sensor ( outputs 1 when there is no water in pipes)
• I2: Sand separator is working ( outputs 1 when Sand separator is working)
• I3: Reset sand separator (when user presses a button, system resets its state)
• AI1: Humidity sensor 1 ( gives value of humidity of soil )
• AI2: Humidity sensor 2 ( gives value of humidity of soil )
• AI3: Pressure in sand filter (gives value of pressure in sand filter)

• Q1: Water pump
• Q2: Sand separator
• Q3: “Non return” valve
• Q4: “Bypass” valve

Functionality:

System is designed to automatically start watering plants when low soil-humidity is detected. Before the water pump is activated, the system checks if any safety sensors are triggered, if so pump activation is aborted.

Safety sensors are:

• Dry running sensor, which is triggered if there is no water in pipes
• Pressure sensor, which is triggered if pressure in sand filter is above limits
• Sand separator is malfunctioned, which is triggered if sand separator is not working

Systems self protection

After the water pump is activated, the system starts monitoring if the sand separator is functional. If in some moment the sand separator stops, after 30 seconds self protection is activated.

Self protection procedure is consisted of:

• Turning OFF water pump
• Closing "Non return" valve
• Opening "Bypass" valve

This way the system will be self-preserved in case that some of its parts are no longer functional.

After self protection is activated, the user is intended to replace/fix the malfunctioning part and press reset button. This way system sensors will be reseted and the system will try to run once more.

Description of the scheme of work with the software

Customizable Control:

The controller program, developed by akYtec specialists using the akYtec ALP software in FBD language, is adaptable to suit specific site requirements.

You can easily customize the time blocks in the program for your applications:

TON1 & TON2 - Delay in opening and closing the gate after a command is given.

TON3 - Gate opening delay if an object gets stuck on the position of the IR sensor.

BLINK1 - Timings for signal lamp blink.

TOF1 &TON6 & TON4 - delay and time for the closing signal if the gates are open for a long time.

TON5 - delay time for the closing signal if the IR sensor did not work (no one passed through).

Full technical description of the project

Functionality:

When a signal is received by the radio relay to open from the remote control, the controller promptly initiates the gate-opening sequence. The gate drive ceases operation upon activation of the first limit switch. Subsequently, the system enters a wait state, allowing sufficient time for a vehicle to pass through. The passage is duly marked once it crosses the path of the infrared sensor. Notably, the gate will remain open if an obstruction is detected by the infrared sensor.

Following this, the system is poised to respond to one of two conditions: either it awaits a signal to close the gate, or it waits for the predetermined duration specified in the program, at which point it automatically triggers gate closure. The drive halts operation upon the activation of the second limit switch.

Additionally, the system offers a feature enabling automatic gate closure in the event that no object passes through the infrared sensor beam after a specified duration.

This automated gate control system guarantees efficient and reliable operation, enhancing security and convenience for residential and garage gate applications.

Our Mini-PLC controllers in an educational process at the Technical University in Košice, Slovakia

Thanks to the exclusive distributor of akYtec GmbH products in the Slovak Republic, VENIO, it is possible to implement educational projects with an emphasis on control and automation using the FBD programming language. Processes are simulated using experimental training boards with various Mini-PLCs that are customized for the students to gain new experiences, skills and develop attributes needed for future automation engineering jobs.

To support the training of professionals, high school and college students, and to familiarize them with programming Mini-PLCs used in automation practice, special programmable relays PR200, PR100 together with analog and digital extension modules PRM 24.1, PRM 24.3 were donated to the Department of Industrial Automation and Mechatronics, Faculty of Mechanical Engineering, Technical University in Košice.

Hands-on training

The aim of the Faculty of Mechanical Engineering is to prepare final year students for professional practice as well as possible. This is done mainly within the technical subjects of the "Industrial Mechatronics" degree program, as well as within related disciplines. At the same time, the program focuses on practical aspects so that students can meet the requirements of automation and control in basic and moderately complex automation tasks from the first day of work. Programmable relays from akYtec GmbH are perfectly suited for a variety of complex industrial applications, process, machine control, and their applications, as well as for simpler home systems. The free development environment akYtec ALP is operated in the form of an intuitive interface supporting the FBD language, in which the user can quickly and easily program and simulate a solution according to the project requirements.

Starting immediately, you can purchase the BPS210-60.S power supply units, which are suitable for supplying mini-PLCs, I/O modules and other devices with a stabilized 24V voltage. The compact design and the wide range of functions allow the effective use of the power supply in advanced automation systems.

In summer, at high temperatures, automatic irrigation systems are a convenient and efficient way to care for plants without human intervention.

The main features of an automatic lawn irrigation system:

1. Watering time. It is best to water in the evening or early morning because the water soaks into the soil instead of evaporating.
2. It is better to water the plants with water at ambient temperature. Since the temperature of well water is usually lower, storage tanks are installed on the surface (or near it) to heat it naturally.
3. Water consumption for lawn watering depends on several factors. There are soil type, grass type, weather conditions. As a rule of thumb, it is better to water rarely but abundantly.
4. It is inadvisable to install strong dynamic sprinklers in and near flower beds. The water jet may break the flowers. Static sprinklers with a head that extends to a great height are the best option. That emulates rain and does not damage the plants.

Concept of an automatic lawn irrigation system with logic control

To create the right conditions for lawn care, an automatic irrigation system based on the Mini-PLC PR200 controller is suggested. The air temperature is measured by a DTS125L PT100 / PT1000 temperature sensor. The water pressure is fed to the sprinklers through the control valve is measured by a PD111 pressure transmitter. The system can also be equipped with a sensor that measures soil moisture. Water from the wells is collected in a storage tank. Irrigating is done by opening and closing valves according to the system settings. The water level in the tank is controlled by a two-level float sensor. A pump station, solenoid valves with sprinklers are needed to control the equipment. The irrigation pump is selected based on the water consumption of the system. The size of the area and irrigation requirements are significant in the selection of the pump station. The PR200 irrigation control algorithm considers air temperature and soil moisture. If the humidity is above the acceptable range, irrigation is stopped. Irrigation is not performed when the temperature is too low or high. The PR200 screen can display measured values (temperature, humidity).

It is also possible to display the most important parameters on the screen, control them manually, as well as the failure mode displaying.

Parameters in failure mode have the following values:

• P - pump state;
• H - moisture sensor state;
• T - temperature sensor state;
• L - water level sensor state;
• V1/2/3 - valve states;
• ± - equipment is working/not working.

Modernization opportunities

The system can be additionally equipped with a weather station. The weather changes and the need for irrigation will be monitored. These systems allow you to monitor air temperature and humidity, wind direction and speed, as well as the amount of precipitation. A cloud service can be used to monitor and control the system remotely via PC or phone. A network gateway is connected to the PR200. The system can work both in automatic as well as in manual mode.

An automatic irrigation system can bring significant benefits to the operation process:

• Landscape maintenance costs are reduced;
• The amount of water needed to water plants is reduced;
• The cost of purchasing plant material is lower because the rate of plant roots is increased. That is due to increased watering efficiency.

The introduction of automation in the park or square landscape maintenance will increase irrigation efficiency and benefit from the first days of operation.

Dear customers, we are pleased to inform you that our partner Prowell Technology Inc. will present akYtec GmbH in the large exhibition TAIROS 2021 (Taiwan Automation Intelligence and Robot show).

The exhibition takes place in Taipei Nangang Exhibition Center, Hall 1&2 (Taiwan) from the 15th to the 18th of December. We gladly invite everyone to visit our partner's booth Q720 in hall 2 and explore our new products.

Warm and low-snow winters have become a serious problem for most ski resorts. To extend the operation of a ski resort, it is necessary to create a snowmaking system. Such a system consists of pumping stations and snowmaking installations. During downtime, in the summer, the hydraulic part of the pumping equipment may jam. To prevent this, an automatic pumping station control system can be introduced into the system.

Control system concept using akYtec products:

• Programmable relay PR200 оf akYtec;
• Analog input module MV110 оf akYtec;
• Digital output module MU110 оf akYtec;
• Pressure transmitter PD100 оf akYtec;
• Submersible level sensor;
• Float sensor;
• Frequency converter;
• Human Machine Interface (HMI);
• Network gateway to access RS485 <=> GPRS cloud service;
• Cloud services such as Microsoft Azure / Amazon Web Services (AWS).

A submersible level sensor and a float sensor monitor the upper and lower water levels in the tank. The Mini-PLC PR200 controller controls the operation of the pump units and gate valve. The pumps are to alternately start every 24 hours for 5 minutes to circulate the liquid and prevent jamming. A simultaneous start is not intended. The pump capacity is regulated by the signal from the pressure sensor PD100. The operating pressure must not be less than 2.5 kgf/cm2. A PT1000 temperature sensor measures the water temperature. In this video, we will show you how you can use the PT1000 macro for direct temperature measurements with the programmable relays PR200. At the same time, the water level in the technical pond is monitored so that in case the pond overflows, the gate valve is opened and the water is drained. If the water level in the pond falls below the limit level, the operation of the pumps is stopped. The opening level of the overflow gate in the technical pond is controlled by a signal from the water level sensor.

Frequency converters are used to drive the pump equipment. The motor is stopped when the lower limit of the pond water level is reached when the water pressure in the general manifold is low and in case of a short circuit.

An RS485-HMI panel can be installed on the front of the cabinet to monitor the status of the unit.

Parameters such as:

• pressure in the general manifold after the pumps;
• the water level in the technical pond;
• current frequency setpoint of the pump frequency converter;
• the on and off time of the pumps can be displayed.

The panel can also be used for system configuration.

Dispatch system and visualization concept

A cloud-based service can be used for remote monitoring, setpoint changes, and data storage. The PR200 is connected to the service via an RS485 interface using a network gateway.

Available functions using the cloud-based service:

• data collection from the PR200;
• displaying data in the form of graphs and tables;
• displaying devices on a map;
• remote management of devices.

Artificial snowmaking can extend the ski season. It ensures good condition in all weather, including light frost and even in temperatures above zero degrees. It is possible to introduce an automatic control system, using akYtec equipment, that will produce a sufficient amount of snow on the ski slopes.

Greenhouse systems are becoming more and more popular these days. The crop yield depends on many factors, including environmental conditions. An automated greenhouse control system may increase crop yields and reduce the workforce.

The main task of the control system is to monitor the vital parameters inside the greenhouse: light level, temperature, and humidity. That allows choosing the optimal control variant to create favorable growing conditions. These parameters can be adjusted to obtain the highest yield of agricultural products.

The systems provide remote monitoring and control of various actuators of water supply or lighting. Operating parameters are updated and stored in the archive. Information is used for analysis, decision-making, and avoidance of abnormal situations. SCADA system and controller record all parameter changes and faults simultaneously.

Concept

Systems can control the maintenance of process parameters within preset ranges. In emergencies, the system signals the need for operator intervention. The automation system performs the same tasks as normal personnel, with greater accuracy and speed. The system consists of a set of sensors, a hardware and software complex for collecting and processing incoming information and forming control signals. The system can be controlled on-site, or remotely via a web-based interface. That allows data collection, analysis, and forecasting.

Water supply control system concept based on akYtec products

The most common source of water supply is wells with deep water pumps located near the complex. Water is used for technological needs, watering greenhouses, washing filters. The water supply system should be equipped with a buffer tank and water tanks with an intermediate pumping station. Water from wells is filtered from mechanical and chemical impurities. Communication between wells, pumping station, filter, reservoirs, and control panel shall be by radio. A repeater should be installed at each point for uninterrupted radio signal reception. It will be more convenient to divide the waterworks control system into several control cabinets according to the following technological tasks: main cabinet, control cabinets of a tank, well, pumps. The operator can monitor the state of sensors and actuators, set operating modes in the SCADA system, receive reports in tabular and graphic form. Operator panels show the status of actuators, sensors, alarms, fill level of the buffer tank and water tank. The on/off time of the pumps is fixed. It is possible to report the water consumption and operating time of each pump. It is also possible to change parameters and monitor operation on the controller.

The greenhouse water supply system can provide:

• simultaneous or sequential operation of pumps;
• maintenance of water reserves in reservoirs;
• recording the amount of consumed water in each well with automatic reporting;
• control of actuator status and water level in tanks in real-time mode;
• local and remote control of pumps;
• protection of pumps against overload and bad quality of power supply;
• protection of pumps against dry running;
• retrieving information from the water flow meter;
• control of the operation of well and overflow pumps;
• logging of operating time of each pump;
• сreation of the event log.

Concept of automatic greenhouse lighting control system

Most vegetable crops grow well under 15-20 thousand lux illumination. The lux is the unit of illuminance, measuring luminous flux per unit area. Such lighting is observed in sunny weather from March to August. Lack of natural light during autumn and winter makes it difficult to grow vegetables. Artificial lighting solves this problem and allows you to maintain optimal light levels regardless of the season and length of the day.

An automatic lighting control cabinet controls the lamp groups in each greenhouse. Information about the current lighting status is displayed on the HMI panel installed in it. From this panel, you can control the lighting in manual mode - turning on/off any row of lights. The advantage of an automated control system is to increase the efficiency of lighting systems and reduce peak currents when turning on the lamps.

Modernization perspectives

The control system, like any design, can be modified and expanded. For example, to monitor the condition of process equipment: inspecting the status of equipment units and eliminating damage in advance. Repair costs will decrease, and productivity will increase with improved control.

The choice of monitoring and control system depends on the business needs of the agricultural producer. Some farmers prefer to have a minimal set of features for their automated control systems. Others are interested in developing and expanding their functionality.

One of the most world popular foods, which is important in our daily lives goes is bread. Hardly anything smells as delicious as freshly baked bread. Bread has been baked all over the world for thousands of years, and its popularity remains intact. We are celebrating "World Bread Day" on October 16. Every year there are more and more new types of bread and pastries. For ancient recipes, which will never lose their value and popularity, we use modern baking equipment.

The rotary oven is an essential element in the bread-making process. It ensures perfect uniform baking, even of the most delicate products. A system based on akYtec products is cost-effective and can be used in rotary ovens from many manufacturers.

Process cycle

The dough is cut and placed on a tray. The trays are placed in a wheeled trolley and inserted onto a rotating platform in the oven. There are three groups of heating elements in the oven. The temperature in the heating element zone and the baking chamber is controlled by PT100 temperature sensors. The fan creates airflow in the baking chamber to evenly distribute the hot air. The frequency converter controls the speed of the fan. The steam generator humidifies the air to achieve high-quality baking in the area of the heating element. A flap controlled by an electric motor is used to recirculate the air inside the oven and discharge it into the ventilation system when the baking process is finished.

Concept of using akYtec products

akYtec's Mini-PLC PR200 programmable relay and a human-machine interface can form the basis of an oven control system. This combination can provide:

• display of operating mode information, faults, and emergency conditions;
• entry and modification of parameters;
• archive for storing recipes, operating times;
• indication of time.

Two akYtec SMI2-M indicators are installed for easy informing. The first SMI2-M displays temperature. The second one displays the baking time. These values can be seen from a distance.

The analog input module MV110 from akYtec with an RS-485 interface ensures the collection of data from temperature sensors installed in the baking chamber and the heating zone. The system makes it possible to bake various types of bread using up to 100 recipes. If necessary, it is possible to switch to manual control mode.

The system continuously monitors the status of the device. In emergencies, it can automatically switch the oven into a safe state. Security functions allow passwords to be set to control the furnace. These prevent unauthorized personnel from interfering with the operation of the furnace.

The control system algorithm

Select the cooking program. The control system starts the fan. The cooking chamber is heated by switching on groups of heating elements according to the selected program. The cooking process begins when the pre-set temperature is reached, which is indicated by a sound signal. The heating process can start automatically at the pre-set time. After placing the products in the chamber, the operator, using the touch panel, start the countdown process. The operator can choose to set:

• fan speed,
• temperature,
• humidity inside the cooking cabinet,
• baking time,
• flap position (%).

At the end of the process, the system offers either to complete the baking process or to set a time for prolonging the process. This function is available in case the person in charge of the cooking process thinks that the products are not ready yet. If no action is taken, the oven goes into a safe state. The furnace signals the end of the process with a beeping sound.

The chicken house has become increasingly popular in recent years. It should be warm, bright, and dry. The conditions should be maintained throughout the year, but it is especially important to ensure that the chickens have the right conditions during the winter period. The main parameters that need to be controlled are temperature, lighting, and humidity. An infrared heater is usually used to maintain an optimum temperature of around +15°C. That is one of the most cost-effective and efficient ways of heating and poses no risk to chickens or humans. There should be about 12 hours of light per day in the poultry house, regardless of the season. Different types of bulbs can be used, including traditional incandescent bulbs. Humidity in the chicken coop is also important, as excessive moisture causes the growth of various pathogenic flora. A natural or supply/exhaust system should ensure an optimum humidity of 60-70%. In winter, it is also important to be able to regulate the degree to which the chicken house door can be opened. They should open and serve as natural ventilation, but the door must not remain open too long not to lose heat.

For optimal housing conditions, health maintenance, and high egg-laying performance, automation systems can be developed using equipment from akYtec GmbH. We offer two system variants to suit different needs.

1. Standard version

In this version, the Mini-PLC PR100 is the base unit. Up to 12 different input signals can be connected to its inputs, of which 4 can be analog (0...10 V, 4...20 mA) or discrete and the remaining 8 only discrete. It is possible, for example, for a heater to be switched on once an hour for about 5 minutes or when the temperature falls below a certain value. In addition to temperature, PR100 allows discrete control of lighting (e.g. 8:00 a.m. - on, 10:00 p.m. - off), fan, poultry coop door opening. For the simplest visualization, a SMI200 panel can be connected to the PR100.

The standard concept using equipment from akYtec GmbH

2. Advanced version

The Mini-PLC PR200 allows you to create a more complex system. The PR200 allows you to smoothly control the lighting, compared to PR100, depending on the photodiode readings so that the transition from darkness to light will not happen abruptly, but more naturally. You can control the operation of the heater more precisely. The analog outputs of the PR200 allow the creation of various climate control algorithms. In addition, the PR200 allows a wide range of visualization options. A human-machine interface can be installed to display the most relevant information such as:

• the temperature inside and outside the chicken house;
• switched on devices (light, heater, fan);
• warning about low temperature, high humidity, etc.

Using various network gateways, the PR200 (or other devices with RS485 interface) can be connected to the Cloud service via a GPRS / Wi-Fi channel.

The advanced concept using equipment from akytec GmbH

A poultry house will provide tasty, nutritious, and environmentally friendly products, as well as fertilizer in the form of poultry manure. The use of automation can significantly improve productivity, ensure consistent product quality and reduce chicken house maintenance time. AkYtec GmbH is a reliable and competent partner for any questions regarding your new project.

Our new Modbus TCP I/O modules of the MX210 series offer a great selection of useful functions, making them the perfect choice for complex and large-scale, as well as minor projects. In this blog post we will show you how you can use the Raspberry Pi 4 Model B as a Modbus Master with our MX210 modules to display measured temperature values on the ITP11-W. Also, we have created a video covering the same topic which you can see below.

The example setup comprises (1) the analog Modbus TCP input module MV210-101, (2) the analog Modbus TCP output module MU210-501, (3) the Raspberry Pi 4 Model B and (4) the digital process display ITP11-W.

The Modbus TCP I/O modules connect to the Raspberry Pi via a bypass-enabled daisy-chain topology. A Pt100 temperature sensor is attached to the input module MV210-101 to achieve a 3-wire measurement. The digital process display ITP11-W is loop powered via the output signal, 4 - 20 mA, of the analog MU210-501.

With our free software tool akYtec Tool Pro, all MX210 modules can be configured easily.

The CODESYS Development System V3 and the runtime system CODESYS Control for Raspberry Pi are used to program the Raspberry Pi. The runtime system must be integrated as a package in CODESYS and additionally installed on the Raspberry Pi.

The next step is to create a new CODESYS project and to name it. We select the runtime featuring multi-core capabilities, making possible industrial use, and structured text (ST) as the programming language. In the device tree, we click Device to open the communication settings. (1) First, we input the correct IP address of our PC. Please make sure that your PC is in the same ethernet network as the Raspberry Pi and the Modbus TCP I/O modules. (2) The second gateway is the Raspberry Pi. Please provide the correct IP address in the respective text field. Afterwards, the username and password for the Raspberry Pi have to be entered.

After establishing a reliable connection to the Raspberry Pi, we add a new ethernet interface to the device tree. Here, the IP address of the PC, as well as the default gateway, have to be provided. Then we add a Modbus TCP Master, the Raspberry Pi, and two Modbus Slaves, the MX210 modules, to the Modbus network. Be sure to always insert the correct IP address of the respective device.

The next step is to write a small program for assigning the measured temperature value to the analog output. We add a Modbus channel to the MU210-501 to write the output variable to the Modbus register of the first analog output. The parameter list in akYtec Tool Pro includes all register addresses with additional information of the respective device in a table. We attach the output variable from our program to the newly created Modbus channel. Now we are going to create a second Modbus channel to read the value from the first analog input of the module MV210-101. The correct register address can also be taken from the parameter list in akYtec Tool Pro. Finally, we connect the Modbus read channel with the variable that holds the measured temperature.

Now let us start the CODESYS runtime for the Raspberry Pi. For that, we click Tools > Update Raspberry Pi. A window will open for the configuration of the Raspberry Pi.

Here you can see the currently installed version of the runtime package on the Raspberry Pi is 4.1. We enter the username and password and start the runtime afterward. The program is now ready to be uploaded. Please click Online > Login and confirm overwriting the existing program. The perspective in the Development System will change to the online debugging mode that allows for a clear overview of all relevant program variables including the measured temperature.

After a successful configuration, the measured temperature value from the MV210-101 is passed to the analog output module MU210-501 so that the sensor signal can be displayed on the ITP11 correctly.

Wind turbines are installations, that harvest wind energy, which is a renewable energy source. Turbines do not generate waste and do not need fuel, which distinguishes them from traditional energy generators. Wind generators can operate in a wide range of environmental conditions: up to 100% humidity and temperatures from -40 °C to +85 °C. The only requirement is wind. Wind turbines generate high voltages and currents. The electrical components must be able to withstand power surges and filter out electromagnetic interference from generators and mains switches. For wind generators to be operational and safe, the electrical parameters (current, voltage) must be continuously monitored, e.g. via a cloud service.

A wind generator is a device that converts the wind's kinetic energy into electrical energy using wind turbines. A typical wind turbine consists of a three-bladed rotor. The wind rotates the blades and, with the help of the rotor, drives a low-speed shaft which, through a stepped gearbox, transmits the rotation to a high-speed shaft that turns the generator. The amount of energy produced by a wind turbine depends directly on the wind speed.

The task and the solution concept

The task is to control the mechanical movements of the wind turbine, the hydraulic brake system, monitoring the meteorological parameters, and the machine working conditions. The control unit at the same time synchronizes the output frequency and connects the generator smoothly through power thyristor assemblies to the power grid. This process is carried out by a controller built into the control unit. Its program is stored in an inaccessible firmware in a permanent memory device (ROM).

Device selection for a control system using akYtec device

• Programmable relay PR200.24.4.2 - 2 pcs. from akYtec
• Analog input module MV110-8A from akYtec
• Digital input module MV110-16DN from akYtec
• 3-Phase Power Measurement Module ME110-230.3M from akYtec
• Power Control Unit
• Network Gateway for accessing to the Cloud Service RS485 <=> GPRS
• Cloud service e.g: Microsoft Azure / Amazon Web Services (AWS)

The first programmable relay PR200 (master) controls the start-up of the generators, ensures the data exchange between digital and analog sensors with the Cloud Service and the MV110 modules. The second programmable relay PR200 (slave, connected via RS485 interface) controls power electric automation and the generator access to the power grid. ME110-230.3M 3-Phase Power Measurement Module monitors the mains and the generator parameters (current, frequency, and power factor).

Mini-PLC PR200 controls the switching of the power thyristor assemblies and ensures that the generator is connected smoothly at synchronous frequency. Provided cellular coverage of the installation site, it is possible to remotely control start-up and monitor the operating parameters of the wind turbine in a Cloud-based Service using a PC, or via an app. This allows the data parameters to be monitored processed and visualized. It is also possible to assign access rights for the turbine management, according to the management company's internal security system.

The system can monitor the following wind generator parameters and display them on the PR200 screen:

• Voltage, currents, power factors, and frequency on generator output
• Rotation speed of the turbine propeller and generator shaft
• Nacelle downwind orientation and wind speed
• Temperature of the units, turbine bearing, and oil in the gearbox
• Electrical energy production, instantaneous power
• Status of discrete sensors in the wind turbine control system
• Status of electrical automation control signals

Due to its highly developed technology and economic and environmental advantages, wind energy is one of the fastest-growing and most promising renewable energy sources. The Global Wind Energy Council (GWEC) estimates that wind power will meet 34% of global electricity demand by 2050. Offshore and onshore wind farms will become increasingly important in global efforts to reduce the effects of climate change.

What is the MX210?

That is not just another series of expansion modules with the Modbus TCP protocol. It is a universal self-sufficient device that can be used with or without a controller. Due to a wide range of supported protocols, the module can simultaneously interact with 4 TCP clients (masters) over different communication channels, making it an excellent choice for industrial automation systems, IT systems for network management and monitoring, as well as in IIoT. A vast selection of different modifications for IOs makes this module very flexible and allows you to easily and quickly integrate it into any system.

Supported Protocols (Modbus TCP, MQTT, SNMP, and SNTP)

Modbus TCP is an open communication protocol based on client/server (formerly master-slave) architecture. The network master monitors the operation of the module. Upon request, the module sends the status of the network input and receives commands for controlling the outputs from the master device of the network. The MX210 collects data about automation objects and transfers this data to PLCs, Cloud, SCADA, PC, or other control devices. Each module facilitates cabling and system management. It allows simultaneous communication with 4 TCP clients (masters). The MX210 series modules can work with the Сloud. Sending messages comes from the device to the broker and vice versa. Moreover, additional network gateways aren't required to connect.

The MQTT protocol (Message Queuing Telemetry Transport) is an event-driven protocol based on the TCP/IP stack that uses the Publisher/Subscriber network model. MQTT has many advantages, such as low network traffic, compactness of the message, the ability to work in an unstable data transmission channel.

SNMP (Simple Network Management Protocol) is an Internet standard protocol for collecting, organizing information about managed devices in IP networks and modifying this information to change device behavior. That means MX210 can connect to IP networks via SNMP. The modules with SNMP are convenient for IT engineers. They can be easily integrated into existing network management systems to ensure security and monitor conditions that require the administrator’s attention. The modules with SNMP can be used for monitoring environmental conditions including temperature, humidity, airflow, power, as well as for smoke control, unauthorized intrusion control, UPS control, and more.

SNTP (Simple Network Time Protocol) is a time synchronization protocol over the Internet. Each MX210 expansion module has a built-in real-time clock (RTC). Its source of power is a battery, and the time is counted in seconds. RTC readings are used to write to the log file.

Features and capabilities

The MX210 modules have built-in encrypted flash memory and built-in alarms. The configuration software (akYtec Tool Pro) is available at no additional cost. The modules are configured via Ethernet or Micro-USB cable. No external power supply to the module is required when connected via USB. Ethernet connectivity allows working with a group of modules at once.

The automatic distribution of IP addresses is carried out using the service button, which is on the device. It allocates to the modules the addresses previously prepared in the akYtec Tool Pro configurator. That allows connecting all modules with no need to pre-configure them. Time spent configuring the devices can be saved, and the same type of installation can be performed multiple times, reducing costs.

An analog input module, MV210-101, is used in various fields of industry and agriculture. It has 8 separately configured analog inputs to which various RTDs types (Pt100, Pt1000, Ni100, Ni1000, etc.), thermocouples (J, K, etc.), position encoders and standard signals (-1 to 1 V, 0 (4)-20 mA, etc.) can be connected. The signal from the sensor measuring the parameter of a physical object is received by the device as a result of successful polling of the device inputs. Through signal processing, noise can be filtered out and input values can be corrected according to specified parameters.

You can find more about all MX210 modifications here.

The MX210 goes with the time, so it has a built-in dual port Ethernet switch. It allows modules to be connected using Daisy Chain topology, which reduces the cost of cable and additional communication equipment. Support for Ethernet Bypass technology enables you to transfer data from one port to another without losing communication with other modules in the case of a device failure.

Last but not least, MX210 can solve many problems such as a lack of I/O points, device compatibility with other devices in the network (interface, protocol, etc.), long distances between the PLC and field devices. Due to the vertical orientation of the removable screw terminals, the modules have become more compact. That increases the concentration of IOs points and reduces the size of the control cabinet. After the cables are connected to the module terminals, they are closed with a cover, which ensures safety and a neat appearance. A cable channel is provided under the front cover. MX210 can be easily mounted on the DIN rail or the wall. The modules are equipped with diagnostic LEDs that are bright and visible in the dark.

The above-described MX210 extension module can be selected and ordered here.

To save you some time, we have created a video showing each step of the article. You can watch the video below.

• This is a sample project on how to use the MX110 modules the corresponding Configurator Mx110 and ALP software. The goal of the project is to use the PR102 to acquire and transmit measured values and control digital inputs and outputs via the modules.
• For this we need a PR102, the I/O modules MU110-24.8I, MV110-24.8A, MK110-24.8D.4R and a Pt1000 temperature sensor.

Step 1: Configuration of MX100 modules

Note: Please note that the module is connected to a PC via a RS485 interface. You can use the akYtec converter or any USB-RS485 converter for this purpose.

When the module is connected to the configurator for the first time, it is connected according to the factory settings. Then the network parameters are read out. These are set and saved as shown in the picture. If the connection does not take place, set the corresponding COM port and click on "Use factory settings" as shown in the figures below.

If the device was previously connected, enter the previously used settings and click "Connect".

Note: To restore the factory settings, please refer to the device's instruction manual.

Set the network parameters that you want to use later in the akYtec ALP for PR102, such as baud rate, device address and protocol.

The procedure for the MV-110-24.8A and MK110-24.8D4R modules is the same. Set the network parameters that you want to use later in the akYtec ALP for PR102, such as baud rate, device address and protocol.

MV110-24.8A settings.

In case of the MV110-24.8A the input signal has to be set additionally. It is sufficient to set the type of the connected sensor for the first steps.

MK110-24.8D4R Settings

Step 2: Connecting the devices

As shown in the picture, the modules are connected to the PR102 via the RS485 interface and the DTS125L-PT1000 is connected to the analog input 1 of the MV110-24.8A.

Connection diagrams can be found in the devices' instruction manuals. The instructions can be found at the links below:

• PR102
• MV110-8A
• MK110-8D4R
• MU110-8I

Step 3: Programming in akYtec ALP

Create a new project after starting the akYtec ALP and select the PR102. Then the serial COM port is set over which the PR102 is connected.

The RS485 interfaces are set up via the device configuration and network variables are created. The settings must be the same as for the MX110 modules! (see pictures below).

The respective Modbus registers were taken from the instruction manuals of the individual modules.

Step 3.1 MU110-8I

In case of the MU110-8I module, this is table 6.2, section 6.3. As of here, you need information about the register and the data type in which you want to use the data.

Note: The device address is the same as in the module settings

Step 3.2 MV110-8A

In case of the MV110-8A module, this is the Table 6.1, section 6.3.

Note: The device address is the same as in the module settings.

Step 3.3 MK110-8D4R

In case of the MK110-8D4R module, this is the Table 6.1, section 6.3.

Note: The device address is the same as in the module settings.

The circuit is constructed as follows:

The network variables are connected to the corresponding variables.

It should be noted that the input AI1 is also set to the input signal 4-20mA.

You can test the functionality of the circuit by enabling online debugging mode.

Description
We offer you the opportunity to familiarise yourselves with our programming environment akYtec ALP as well as to acquire practical programming skills with it.

Content:

• General
• User Interface
• Usage Basics
• Device Configuration
• Variables
• Library: Functions, Function blocks, Project Macros, Display Elements
• Circuit Program Development
• Display Programming

In the previous episode: Having done the unboxing and a quick overview of PR200, we connect this Mini-PLC to the PC, configure it, and create a user program. The program is very simple and easy to follow since it deals with push-buttons and a few LED pilot lamps (i.e., only digital I/Os involved).

In our second video of this series, we enrich the project with more devices, including those with analog inputs and outputs, and make some of them communicate via Modbus. Additionally, you will learn how to configure the PR200’s LCD, i.e. make good use of it.

For starters, we look over the contents of the delivery package, analyze PR200's functionality based on all the elements available on the device front.

Then we show the real-time operation of the PR200 wired to several pushbuttons and pilot lights. Having connected the Mini-PLC to a PC using the USB cable supplied, we make the PC detect the device.

Once the device has been successfully detected, we create a simple project and have some insight into the device programming with the akYtec ALP software.

Our customer support team has been receiving questions on Modbus communication between SMI200 and PR200, so we decided to prepare a sample project which thoroughly covers this topic.

Not only provides this sample project step-by-step instructions but also a clear explanation of each significant step, which unobtrusively makes you a more proficient user of the akYtec ALP software tool.

Having gone through all the pages, you will answer the following questions by yourself:

• - How to establish a successful communication between SMI200/PR200 and PC?
• - How to make PR200 operate as Master, read some values (INT and REAL) from a Slave device (SMI200), and display them on its LCD?
• - How to make SMI200 operate in the Master mode, read some values from a Slave device (PR200) in two ways – using network variables and directly from Modbus registers – and display them on its LCD?

The in-depth description of the project and the project files you can download here.

With each of these extension modules, you can add 4 analog inputs and 2 analog outputs to your PR200’s built-in I/Os. Under ‘built-in’ is meant that the PR200 recognizes these inputs and outputs as its own. Thus, the I/O extension over an internal bus is not only easier to implement but also beneficial in terms of performance – no restrictions of the communication protocol as if adding I/Os via Modbus, etc.

The 4 analog inputs are individually configurable for a wide variety of RTDs, TCs, as well as standard linear current (4-20mA, 0-20mA, 0-5mA) or voltage (0-1V, -50...50mV) signals, and even resistive signals in the range of 0...3950Ω. Now you can smoothly connect Pt100 to the PR200, not to mention many other temperature sensors such as Pt1000, Pt50, Pt500, as well as thermocouples of type J, N, K, S, and more. On the output side, you can select from 0-10V, 0-5V, 4-20mA, 0-20mA, or 0-24mA when configuring either of outputs.

Depending on the device variant, PRM-24.3 or PRM-230.3, you can order the module either for 24V DC or 230 V AC supply voltage to meet your project requirements better.

The input configuration options include 9 types of the most commonly-used RTDs and 9 types of most common thermocouples. The universal analog output can be configured for a linear current or voltage signal, thereby choosing from a wide variety of the signal ranges, e.g., 4-20 mA, 0-20 mA, 0-5 mA, 0-10V, 2-10V, or 0-5 V. The input can connect to an RTD in a 2-, 3-, or 4-wire depending on the sensor available.

The NPT4 compact temperature transmitter is powered by 24 V DC and is reverse-polarity protected. Galvanic isolation of 1.5 kV is provided for three groups – the power supply, input, and output.

A USB port provides a convenient connection to a PC for simple and precise configuration with Windows software available on the akYtec webpage at no charge. The NPT4 can operate across an extended ambient temperature range between -40 and 70 °C.

Each segment can light green or red depending on the setpoint limits so that the operator could instantly evaluate if the process is safe or unsafe. If the unit is flashing with three red segments on both sides, a short circuit or sensor break has occurred. The corresponding alarm alert can be transmitted to a supervisory device via the NPN transistor output. With this output, the ITP15 is also able to handle a local on/off control of a load of up to 200 mA, 42 V DC.

On the input side, this bargraph display unit can be used for connecting to any linear voltage or current signal of 0(2)-10 V or 0(4)-20 mA respectively. The input signal can be scaled to the display range within 0...100%.

Either horizontally or vertically, the ITP15 bar graph display can be effortlessly installed in a standard 22.5mm mounting cutout without any tools, e.g., screwdrivers, hex wrenches, drill bits, etc.

Dear custumers, we are pleased to inform you that akYtec GmbH will participate in the largest international exhibition for electrical automation technology SPS IPC Drives. The exhibition takes place in Nuremberg from the 26th to the 28th of November. We gladly invite everyone to visit our stand 8-410 in hall 8, talk with us, and explore our new products.

Among many improvements and new functions, the online I/O status monitoring is worth mentioning the most. Now you can observe the user program being executed in the device in real time. This function saves a considerable amount of time when troubleshooting during commissioning. Online I/O monitoring should be the first step towards full online debugging. Therefore, the program run-stop feature, the possibility of editing a required value, step-by-step program execution, and other features will be added shortly.

Another big step towards simplifying programming with akYtec ALP is the templates of network variables. You can save a whole set of adjusted network variables as a file. This file can be later used for another slave device, even in another project. For example, there is an MX110 expansion module (or any other RS485 I/O module) connected to a PR200 programmable relay. The PR200 is the Master device, and the MX110 is a Slave device. You have defined and configured a variable for each input of the module. Now this set of variables can be saved as a file. Whenever you need to add another I/O module of this type to the current configuration or to another project, you can use this file. As a result, the module will be configured instantly, saving a lot of time and effort. It is planned to add a similar function for network variables of the master device as well.

Despite many similarities, the MV110-24.8A and MV110-24.8AS extension modules have some differences. The most important are:

• - Support for temperature sensors. The 8A supports a variety of RTDs and TCs. The 8AS does not support any temperature.
• - Different sampling times of the inputs. When comparing the standard current and voltage inputs of the MV110-24.8A and MV110-24.8AS extension modules, the difference in sampling time per input is significant. It takes 5 ms for the input of the 8AS to sample a value of the signal. The 8A needs 0.6 s (600 ms) to do the same.
• - Support for digital signals. The 8A can be configured for digital signals, the 8AS however, does not support digital signals. For this reason, the MV110-24.8A input module is particularly useful when the system contains several digital signals in addition to analog signals, and the purchase of an additional digital module seems economically unreasonable.
• - Support for resistive position sensors. The 8A can operate with 900 ohm or 2 kohm position sensors, in contrast, the 8AS can not work with resistive sensors.
• - Support for different types of voltage signals. The 8A can process signals from 0-1 V or -50 ... +50 mV, and the 8AS only 0-10 V.

Making the choice

If you only need to process standard current signals of 4-20 mA, 0-20 mA, 0-5 mA, or voltage signal of 0-10 V, it is better to take advantage of the shorter sampling time of the MV110-24.8AS' inputs.

In other cases, for example, if you need to process 0-1 V or -50...+50 mV signals, or if you require a combination of digital and analog inputs, or signals are processed by RTDs or TCs temperature sensors, then the input module MV110-24.8A is the way to go.

Digital panel meters from akYtec stand out with their compact and exclusive design. The unique combination of the rectangular front and cylindrical back provides advantages in the mounting process as well as in reading the screen. Furthermore, these panel meters are configured simply with three function buttons without the need for any programming software.

The cylindrical mounting part allows akYtec's digital panel meters to be fitted into standard Ø22.5mm mounting cutouts, which significantly simplifies the installation process compared to traditional panel meters of a rectangular form. Electrical enclosures or control panels use holes of this diameter for the installation of standard signal lights or buttons. Thanks to their shallow depth (65 mm), not only can these panel meters be installed in control cabinets or control panels but also in push-button housings.

effortless installation into push-button housings owing to shallow depth (65 mm)

Panel meters from akYtec fit into the standard mounting cutout of Ø22.5mm, which is usually used to install standard signal lamps or push buttons

The rectangular front (48 x 26 mm) provides much more area to display information than the front of complete cylindrical Ø22.5 mm cases.

The PR200 mini PLC from akYtec can display the values of BOOL, INT or REAL variables, as well as constant text on its LCD screen, which is not the case for the STRING variables. The STRING data type is not supported by akYtec ALP programming environment. But what can be done if you want to display a variable text?

Suppose a PR200 mini PLC and a TRM202 process controller are connected via the RS485 interface and via the Modbus protocol. The goal is to display the firmware version of the TRM202 process controller on the display of the PR200 mini PLC.

According to the TRM202’s user guide, the ASCII code of the firmware version of the process controller is stored in binary format in 4 consecutive registers beginning with the address 0x1004 (hex).

Therefore, three steps are required:

• - read data from the corresponding registers
• - decode the data
• - display the data as ASCII symbols on the PR200’s display.

The 4 registers can be read into 2 INT variables, for example.

These network variables can now be processed by the display manager of akYtec ALP. However, that would not make sense, since they are only 32-bit integers that have nothing to do with ASCII symbols. Therefore these two variables should be divided into single bytes. For this purpose, the ASCII_CHAR macro should be used. This macro and its description are available in the Component Manager (akYtec ALP: Main menu > Device > Component Manager).

The ASCII_CHAR has two INT inputs and one INT output. If an INT variable is applied to the first input and the sequence number of the required byte of this variable to the second input, the macro will output an INT value generated from the 8 bits of the corresponding byte.

Since each network variable, Version_TRM202_r1 and Version_TRM202_r2, contains 4 bytes, the ASCII_CHAR macro must be applied to each byte to get 8 INT values.

Each of these INT values is a code that corresponds to a symbol from the ASCII character set. It still remains to decode these ASCII codes and display the correct characters on the PR200’s LCD screen. This is where the Dynamic Box display element comes into play:

Dynamic box is used to display one of the text lines from a list, depending on the value of the referenced Integer program variable. The display element Dynamic box has three parameters: variable, row list and length.

The Variable parameter can be used to reference a program variable. The Row list is a table with lines of text. In this case, the row list is the ASCII character table. Length defines the number of characters that can be displayed.

To display the entire line of the firmware version of the TRM202, 8 Dynamic Box display elements must be used:

‘The firmware version of the TRM202 on the LCD of the PR200’ ‘The firmware version of the TRM202 on the LCD of the PR200’.

Modern PLCs are powerful, high-performance devices that are protected against high levels of electrostatic discharge (ESD), large transient voltage fluctuations, electromagnetic interference (EMI), and are specially designed to operate in harsh industrial conditions. In most cases, these devices support many interfaces (RS485, Ethernet, CAN, LVDC. etc.) and communication protocols (Modbus, Profibus, CANopen, EtherCAT, DeviceNet, EtherNet I/P, etc.). PLCs are no longer limited to one programming language. They can be programmed in one of five languages - Function Block Diagram (FBD), Instruction List (IL), Ladder Diagram (LD), Sequential Flow Chart (SFC) and Structured Text (ST) - which correspond to the worldwide valid standards for programming languages of programmable logic controllers IEC 61131. Some PLC programming environments allow developers to flexibly combine different programming languages in a single CPU, e.g. using CODESYS V3.5. In addition to the support of many data types, extensive libraries, visualization elements, CODESYS can also implement its own protocols and create object-oriented control programs. Thanks to an extensive development environment and large memory capacity, complex and large process control projects for almost all industrial purposes can be implemented with one PLC.

Such high performance is not necessary if efficiency has a higher priority. Because of this, many manufacturers produce different simplified devices dubbing them "Programmable Logic Relay" (PLR), "Compact PLC", "Mini PLC", "Smart Relay", Small Controller", etc. These devices are typically non-modular and have less storage capacity, fewer interfaces/protocols and fewer I/O points, making them more compact. These simplifications lead to a reduction in device costs. They are at least two times cheaper compared to PLCs. Another advantage of the PLRs is that they are easier to program because they are usually delivered with an intuitive and user-friendly programming environment, saving time and money.

The akYtec GmbH does not remain on the sidelines of this trend and offers PLR-like devices as well – Programmable Relays of the PR1XX series, and a more sophisticated device of this kind – PR200. They are all equipped with a real-time-clock and can be expanded with I/O-modules. The easy-to-use and free "akYtec ALP" software tool can be used to create simple and effective solutions for industrial needs such as pump control, lighting, HVAC, home automation, and other simple automation tasks without complicated and expensive PLCs.

Besides the innovative research and development activities, the company’s new products will be presented there.

There is also integrated a department for technical support in the center. Our team provides you with qualified and comprehensive assistance including selection, installation, configuration and use of our products.

The technology center is located on Leipziger Platz 15, 10117 Berlin, which is in the immediate vicinity of Potsdamer Platz.

PRM Extension Modules from akYtec

Modularity

Prior to the appearance of the PRM Extension Module, our Programmable Relay PR200 was a compact small controller with a total of 22 inputs and outputs. In most cases it is good to have a compact device, but performance and flexibility often play an important role as well. Modularity is the key to meeting the growing demands of your control system. With the PRM Extension Modules, the PR200 mini controller is no longer a compact PLC. Now it's a modular expandable device with up to 54 I/O points.

Inputs & Outputs

The PRM module is equipped with 8 digital inputs and 8 digital outputs.

The inputs process signals from sensors with switch contact output or PNP open-collector transistor outputs.

The outputs serve as normally open relays and can be connected in series with a control or indicator device. They are rated for up to 5 A, 250 V AC and up to 3 A, 30 V DC, regardless of the input voltage.

If communication with the PR200 has been interrupted, the outputs of the PRM module take values previously defined by the user. This function is called output safe state.

Internal bus and easy configuration

The modules are connected to the compact mini PLC PR200 (hereinafter ‘base device’) via an internal bus. This bus is implemented as an SPI interface and a short flexible flat cable consisting of 10 wires.

The internal bus provides a fast and easy-to-configure connection of the PRM modules to the base device. It only takes a few clicks to add a PRM module to your project in akYtec ALP, the software for programming the base device. Unlike any Modbus-based extension module, a PRM module eliminates the need to deal with Modbus registers and functions. Once a PRM module has been added to the project, its inputs and outputs are available for direct linking to the variables and function blocks in your project.

Power supply and galvanic isolation

The requirements of the supply voltage of a PRM Extension Module differ depending on the device variant. It can be either 24 V DC or 230 V AC. With the 24 V device, a debounce filter can be set in the range of 0 ... 255 ms at its inputs.

Thanks to its own voltage terminals, each PRM unit can be powered by a separate power supply. As a result, the base unit and the PRM Extension Module can cooperate with different supply voltages.

The power supply, input and output terminals are galvanically isolated from the internal circuits with isolation voltage up to 2830 V, ensuring additional device reliability and user safety.

Enclosure

The device has a compact enclosure that can be easily snapped onto a 35 mm standard DIN-rail without the need for any tools. Due to its design and depth, each PRM module can be mounted not only in a control cabinet but also in a distribution board.

Each input and output of the device has an LED to indicate its status. The power and error indicator is also available on the front panel of the device.

The PRM expansion modules feature removable I/O terminal blocks for quick and easy device replacement.

We continue providing you with more sample projects on our devices. This time the spotlight is on the MSD200 Data Logger.

In order to save you a lot of time and help you with the operation and configuration of the MSD200, our team has developed a comprehensive sample project. This sample project ‘Data logging and data evaluation’ is divided into two parts.

The first part contains information about the data logging itself. To show you how the MSD200 can be used for this task, additional devices need to be connected to it. In this project, they are:

• - NPT1 Temperature Transmitter
• - PVT100 Humidity and Temperature Transmitter
• - MV110-24.8A Analog Input Module
• - DTS125L PT100 / PT1000 Temperature Sensor

There are implemented 3 log-channels with these devices, using analog inputs/outputs and the RS485 interface. This means that you can find here configuration examples for log-channels, Modbus settings, monitoring of real-time values. At the end of this section, we will show you how to export an Excel CSV file with the built-in File Manager.

In the second part of this sample project, we suggest a method for the evaluation of all logged data with the help of Microsoft Excel. Of course, you can do this with another spreadsheet program in a similar way.

The detailed project description can be found on our product page of the MSD200 Data Logger > Product description > Sample project.

Starting with the exterior design, going through the electrical installation until the configuration of:

• Password function [2:25]
• Decimal point position [2:33]
• 4 mA – lower limit (-999…9999) [2:42]
• 20 mA – upper limit (-999…9999) [3:02]
• Damping time [3:25]
• Square root function [3:33]
• Alarm function [4:09]
• Lower setpoint limit [4:21]
• Upper setpoint limit [4:39]

The ITP14 is a universal process display with a voltage/current input that can be set to either 0-10 V or 4-20 mA.

The ITP16 is a temperature display that can read many RTDs, such as Pt100, and different types of thermocouples.

In addition to the ergonomic design, compact enclosure and all features of our ITP11, the ITP14 and ITP16 process displays also feature an NPN transistor output. This output can control a load up to 200 mA / 42 V DC. This makes it possible to implement an ON/OFF control or just to use it as an alarm output.

PLCs and mini-PLCs are very similar in terms of function, hardware, operation, design, etc., which makes them quite replaceable and universal devices. The main distinguishing feature of these devices is the programming software. For this reason, the user has to be thoroughly familiar with the programming environment in order to be able to program the device. Sometimes it is a time-consuming activity. To save your time, we have decided to provide you with various sample projects on programming our programmable relay PR200. Our main goal is to build as many projects as necessary to encompass all the functionality of the akYtec ALP programming environment.

According to our technical support team, the processing of analog inputs and using of the RS485 interface are the most frequently asked questions about the PR200 and akYtec ALP. On this basis, we have decided to dedicate or first sample project to exactly this topic.

There are many ways to use analog inputs of a PLC in industrial automation, HVAC, or agriculture. One of the most common is the monitoring of temperature and humidity. For this purpose, akYtec GmbH offers the following devices:

• - Temperature sensor DTS125L
• - Temperature transmitters NPT1 and NPT3
• - Humidity and temperature transmitters PVT10 and PVT100

For this sample project, we use two temperature sensors – DTS125L-PT100 and DTS125L-PT1000 – to monitor the temperature and display the settings of the configurable analog inputs (4-20 mA, 0-10 V or 0-4000 ohm). The PT1000 is connected directly. We simply use an analog input of the PR200 for 0…4000 ohm and utilize a ready-to-use macro 'Pt1000' from the Online Macro Database. One could do the same with the PT100 if no negative effect on the signal accuracy would occur. To solve the problem, we connect our PT100 sensor via the temperature transmitter NPT1. The NPT1 converts the signal of the sensor into the signal of 4-20 mA so that our programmable relay PR200 can evaluate it.

The Programmable Relay PR200 from akYtec is available in many variants, depending on the supply voltage, the number of the RS485 interfaces and I/O points. Since this project requires two RS485 interfaces and a 4-20 mA output, the PR200-24.2.2 fits best here. This programmable relay is powered by 24 V DC and features four analog inputs, two 4-20 mA analog outputs, and two RS485 interfaces.

The humidity and temperature transmitter PVT100 was selected for the humidity measurement. This device can be connected to an analog input or to an RS485 interface. We prefer the second option to guide you through the Modbus settings in the akYtec ALP. The second RS485 interface is used to output data from the PT100 temperature sensor and display them on the SMI2 RS485 Display. The humidity value is displayed on the ITP11 process display, which is connected to one of the analog outputs of our compact PLC.

The intelligent relay PR200 has a 2-line 32-character LCD display. In order to familiarize you with the programming of this display, we have brought the data of all connected sensors on the display.

The project file and its detailed description can be found on the product page of the PR200 programmable relay > Product description > Sample project.

Interface RS485

The RS485 interface is quite common in fieldbus networks. This high-speed and interference-resistant serial interface makes it possible to network many devices via a common bus line.

The data are transferred via two wires (D+ and D-) in form of a "symmetrical" (differential). The maximal distance between the extreme devices may reach 1200 m. With an RS485 amplifier the maximum distance can be even greater. If the communication line is 100 m or longer, it is strongly recommended to use termination resistors (from 100 to 250 ohm) at both ends of the line to eliminate reflections. The number of devices in any RS485 network may not exceed 32 nodes (without repeaters).

Typical fieldbus network based on the RS485 interface

A usual office PC is not equipped with the RS485 interface compared to an industrial PC. For this reason, an interface adapter is required to connect a PC to a fieldbus network. For this purpose, akYtec offers USB-RS485 interface converter IC4 and RS232-RS485 interface converter IC3

Interface RS232

This interface is based on EIA RS232C and is intended for a serial connection between two devices. It is often used to connect external equipment to a PC. The RS232 interface implements an asynchronous serial communication form of signal transmission over two lines, TxD (transmit data) and RxD (receive data), while the signal amplitude is measured relative to the grounding line (GND).

Since data transmission over the RS232 interface is normally asynchronous, there is a low interference immunity and thus the route length is limited to a few meters. Two separate communication lines allow full-duplex data transmission, meaning reception and transmission of data happen simultaneously.

The RS232C specification does not contain a description of the connector to be used. However, the most commonly used type is the 9-pin and 25-pin connectors (DB9 and DB25).

Ethernet

Ethernet is a data transfer technology for connecting devices to computer networks, usually to local area networks (LAN). Data access in these networks is controlled by the CSMA/CD algorithm. This acronym stands for Carrier-Sense Multiple Access with Collision Detection. In this method, devices only exchange signals when they have detected an idle state on a wire in order to avoid collisions. All forms of Ethernet support up to 1024 nodes in a network. This interface is widely used due to its high data bandwidth and immunity to interference.

Interface USB

Standard USB was developed as an alternative to the previous network standards RS232 and IEEE 1284 to connect peripheral devices to PCs. Currently, many devices are equipped with the interface USB 2.0, so that data can be transmitted at the ate up to 480 Mbps. The USB interface as well as the RS485 interface can transfer the data over two wires (D+ and D-) and the logical levels are identical to those of the RS485 standard. This interface has two additional wires (Vcc and GND) for supplying power to the connected device (provided that its current consumption is 500 mA max.).

Once the appropriate driver is installed, the OS automatically recognizes the device connected to the USB port as a COM port and operates in the standard asynchronous transfer mode, which is used to operate with a hardware COM port.

Asynchronous data transmission

The RS232 and RS485 interfaces support asynchronous data transmission. The data are transmitted byte to byte. To signify the beginning and end of each byte (character) to be transmitted, each byte is framed on both sides by a start and a stop bit. The bits between the start and the stop bits are called data bits. They can be 5, 6, 7, or 8 bits. The number of standard data transfer rates have been established for asynchronous transmission: 50, 75, 110, 150, 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200 bit/s.

Concerning the protocols, most of akYtec devices communicate via Modbus ASCII/RTU. Further details will be published in one of our next articles.

Interface a shared transition point between two or more functional units (device, PC, etc.) defined by common characteristics of physical interconnections, signal characteristics, and functional characteristics of interconnection circuits.

Protocol is a standardized set of rules for data transmission over a communication interface.

The communication interfaces used in the industry can be of two types:

Point-to-Point. There is only one transmitter and one receiver in the network; the data is transferred only in one direction per signal line.

Point-to-Multipoint. There is one transmitter and several receivers in the network; the data is transferred only in one direction per signal line.

The main characteristic of any communication interface is its baud rate. This rate determines the number of bits transmitted via a line per second (bit/s, Mbit/s, etc.). Usually, the baud rate consists of "payload" and "overhead". The overhead typically includes the packet format or protocol frame: source/destination bits, error checking bits, control bits, etc. The payload is the net data rate or the effective data rate. The payload varies depending on the particular interface and protocol and can be from 30% to 90% of the baud rate. This must be taken into account.

Interfaces and protocols used in akYtec devices:

Device compatibility

Device compatibility is the capability of devices to exchange data with each other. Each device participating in the data exchange must be equipped with a specific interface and support a specific protocol. Nevertheless, even in this case, the ability of exchange data is not always possible because one device may not be able to send the information that the other is supposed to receive. The question, therefore, lies in what to do if the devices support the same data type but have different interfaces and/or support different protocols. It is necessary to use interface adapters or protocol translation gateways.

Interface adaptera device with two or more interfaces that transfers the data from one interface to another. However, information transmission is carried out without its conversion. This means that the devices connected via an interface adapter should support the same protocols.

Protocol transmission gateway (or protocol converter) is a device that converts the data from one protocol to the other. In addition, a protocol converter can also serve as an interface adapter. In contrast to an interface adapter, however, the protocol converter must be configured for which data via which protocols is to be transmitted in the communication network.

Read more information in our post 'Interfaces and protocols used in akYtec products – Part 2'.

• - Insufficient PLC resources, e.g. a low number of inputs and/or outputs
• - Issues with compatibility with other devices in the network (interface, protocol, etc.)
• - Large distances from the PLC to field devices.

To solve this and similar problems, remote I/O-Modules have been developed. These modules are used to set up decentralized systems, to control industrial objects and processes. The expansion modules can complement such systems, with multiple inputs or outputs, thus ensuring more functionality and flexibility of the systems. Among many decentralized systems, the single-master systems based on the RS485 serial interface and Modbus protocol have become the most established in industrial automation. That is why akYtec I/O modules have the appropriate interfaces and protocols.

In addition to the inputs and outputs, most modern I/O modules offer many different functions, such as cold junction compensation, linear signal scaling, wire break detection, safe mode, restoring factory settings. etc. The integration of more and more PLC functions in the I/O modules is one of the prevailing trends. This makes modules more independent and efficiently expands the control systems without significantly increasing the CPU utilization of the PLC. The akYtec Mx110 series extension modules are based on the same principle and offer a cost-effective and flexible solution for distributed automation systems.

The akYtec modules are delivered in a compact IP20 enclosure and can be operated in a temperature range of 20...50 °C. Thanks to the universal design, the enclosure can be mounted either on the DIN rail or on the wall. The plug-in terminal blocks make it possible to remove the device from the DIN rail or the wall without disconnecting the cables individually. The power supply circuits are protected against overvoltage due to galvanic isolation. Reverse polarity protection is also available.

The modules are configured using the special PC software (Mx110 configurator), which is available for free download from www.akytec.de. This configurator is universal and therefore suitable for every module of the Mx110 series. Each of these modules can be connected to the PC via a USB-RS485 converter from akytec or any other similar converters. If the module is successfully connected to the PC, the configurator automatically detects the device version and offer the appropriate parameter set.

All akYtec I/O modules have been tested for electromagnetic compatibility (EMC) and meet the high requirements of IEC 61326-1. This means that these modules can be operated under long-lasting electromagnetic interference.

The product portfolio of the I/O modules from akYtec is diversified and divided into several groups:

• Analog input modules (8A, 8AS) These modules feature universal and configurable analog inputs for a wide range of TCs and RTDs. Various standard signals, e.g. 4-20 mA and 0-10 V are also supported.
• Digital input modules (16D, 16DN)The inputs of these modules can receive various DC signals from switch contacts (relays, pushbuttons, etc.) and from 3-wire transmitters with PNP or NPN output.
• Digital input and output modules (8D.4R)These modules can process up to 8 input signals from switch contacts and operate up to 4 relay outputs.
• Analog output modules (8I, 6U)These devices feature 8 outputs 4-20 mA and 6 outputs 0-10 V.
• Digital output modules (8R, 8K, 16R, 16K)These modules allow you to extend your PLC with up to 8 or up to 16 relay or transistor outputs.
• 3-phase input modules (3M)In addition to measuring network current and voltage, the modules of this type can measure active, reactive and apparent power, fundamental frequency and phase angle.
• Special input modules (1TD)These modules are designed for signal processing from strain gauges.

When developing an automation system using CODESYS, one often faces the task of implementing a fieldbus system. For example, there is a need to carry out climate control in a vegetable storage facility based on the akYtec SPK207 control panel. Since the SPK207 does not have its own inputs and outputs, expansion modules must be used. There is the possibility to connect the akYtec Mx100 I/O modules via the RS485 interface as well as any other modules via the ethernet interface to this control panel. This article details the steps required to properly configure the SPK207 for data exchange via Modbus protocol in CODESYS v3.5 SP3 Patch 5.

General technique for configuring interfaces in CODESYS 3.5

Interfaces

When the SPK207 is successfully connected to the PC (see Appendix C in the User guide or watch the video tutorial), you can open any previous project in CODESYS or create a new one. The Alt+0 keyboard shortcut opens the Device tree, so that you could right-click on the target device (akYtec SPK2xx) and select the Add device option in the context menu.

Among the appearing interfaces you have to left-click Modbus to select item Modbus COM of the same target device version or an older one.

Confirm your selection by clicking the Add device button in the dialogue window. Now a serial port is available in the Device tree. You have to double-click port Modbus COM to open tab Modbus Serial Port Configuration and set the required parameters.

In a similar way you can add the Ethernet port. Just select Ethernet in the Add Device dialogue instead of Modbus.

SPK207 as Modbus Master

If the desired interface of the SPK207 is to be used as Master, a Master device should be added in the Device tree to this interface. First, add a master device to the "Modbus COM" port by using the option Add Device again. In the opened window select Modbus Serial Master for the COM port or Modbus TCP Master for the ethernet port.

Now the Master devices are available in the Device tree. To configure these devices, correspondent editor can be opened by double clicking on the entry of the master in the device tree.

The Modbus TCP Master has two configuration parameters: Response Timeout and Socket Timeout.

The Response Timeout parameter defines the time interval in which the master awaits the response from the slave. If there is no response during this interval, the master then polls the next slave device. This timeout is taken over for each slave device.

The Socket Timeout parameter defines the maximum period of time in which the master waits for the coming TCP/IP packages.

The COM interface has a similar configuration procedure, but you have to set the Time between frames parameter sinstead of the Socket interface parameter. This parameter defines the length of time that the master waits between the last response (or timeout) and the next query.

When the Master devices are configured, it is time to add Slaves through the already well-known Add device dialogue window. Just select Modbus Slave or Modbus TCP Slave, depending on the port type (COM or Ethernet).

Now the Slaves are available in the Device tree, and you can double click to open the configuration dialog.

The Modbus TCP Slave entry has the following parameters:

• Slave IP Address – the IP-address of the Slave
• Unit-ID – the network address of the Slave device in the range between 1 and 247
• Response Timeout – the time interval in which the master waits for the response from the slave device. The timeout specified here overwrites the general setting Response Timeout of the associated master.
• Port – the port number of the Slave.

The Slave device connected to the COM port has similar parameters:

The further settings are about specifying the communication channels. A channel is a group of register addresses which are arranged one after the other and are only queried for a certain function. To add a channel, click on the Add Channel button in the Modbus Slave Channel tab and then set the necessary parameters in the opened window. All parameter descriptions can be found in the Codesys Online Help (Ctrl + Shift + F1).

When all desired channels are added, activate the ModbusGenericSerialSlave I/O Mapping tab to assign the variables already present in the project to the input and output channels. Simply double-click the field of the required channel in column Variable and click on the button now available to access to access Input Assistant. Here you can select any project variable and assign it to any channel after pressing OK.

There is also a Modbus Slave Initin the configuration dialog of the slave device. This tab is for previously data initialization. For example, when it is necessary to set a sensor type before starting the data exchange. The procedure is similar to that for channel addition.

SPK207 as Modbus Slave

Whether the Ethernet port or the COM port of the SPK207 is to be used in slave mode, a slave device should be added to the Device tree. Simply select Modbus Serial Device for the COM port or Modbus TCP Slave Device for the Ethernet port in the dialogue window Add Device.

Now the slave devices are available in the Device tree. To configure them, a corresponding editor can be opened by double-clicking on the entry of the slave device in the device tree. The following parameters are available:

• TimeOut – the waiting time with possible step size for entries of 500 ms.
• Unit ID – the device network address
• Slave Port – the port number of the Slave unit
• Holding Register – the number of holding registers
• Input Register – the number of input registers

The project variables can be assigned to the holding and input registers in the … I/O Mapping tab. This procedure is exactly like in Master mode.

After performing all settings, simply connect the secondary devices to the SPK207 (master mode) or the SPK207 to the master device (slave mode), and check that the data exchange is correct.

The Modbus settings for the SPK207 are complete.

The MSD200 receives a temperature signal from an RTD through the MV110-8A Input Module connected to the logger over the RS485 interface. Another signal comes directly from a transmitter to one of the four 4-20 mA inputs of the data logger.

To implement this, the data logger must be configured accordingly. This video will help you with the configuration.

Different storage phases assume maintenance of special microclimate parameters that is temperature and relative humidity. There are the following storage phases of seed and table potatoes: drying, healing, cooling, holding and warming before unloading out of the storage.

When all potatoes have been completely loaded to the storehouse, the healing period comes, beginning with ventilation of tubers and their drying. Duration and intensity of this process depend on the crop quality, tuber surface moisture, and temperature during harvesting. Here it is substantial to constantly check the tubers condition because they can lose weight and get dry rot if over ventilated. On the other hand, high humidity of tubers requires intensive ventilation.

After healing phase it is necessary to cool the potato to provide long-term storage. This is a very important period when it is required to avoid significant product temperature variations. In this case, refrigeration equipment is very often the only way to perform cooling in time.

During the holding phase, optimal temperature and humidity must be maintained as optimal conditions for preventing natural tubers-germination.

In any particular case it is needed an individual temperature and humidity mode, subject to the potato variety and further utilization of the potatoes. The germination rate of most potato varieties is noticeably decreased when the storage temperature is lower than 5 °C. Periodic ventilation would maintain the set temperature value and provide enough O₂ ingress.

Sometimes, it is not easy to foresee weather conditions, potato tuber condition (and quality), store particularities and other factors which have an influence on the product safekeeping. Automatic systems can easily meet such challenge, maintaining any preset parameters of temperature, humidity, duration of ventilation, heating or cooling and any other.

A typical vegetable store for 100 – 2000 t is shown in Fig. 1 and the suggested functional scheme in Fig. 2.
