PROGRAMMABLE RELAYS

PR200, ALP, SMI200, PR102, PR103, PR100, PRM

or search frequently asked questions:

What software do I need to program the PR200? How much does it cost? Do I need a specialized cable?

Is it possible to connect Pt100 to PR200?

What tasks does the PR103 programmable relay solve?

How can I change the parameters ‘Start date/time’ and ‘Stop date/time’ of the functional block ‘CLOCK WEEK’ from the front panel of the PR200 or through a variable in akYtec ALP?

I have 2 self-written macros "Average" and "8 INT_M". If the macro "Average" is already used in a project, I cannot import the macro "8 INT_M" anymore. The message appears: The macro "8 INT_M" already exists... replace? Yes/No Why is it happening, and how can I import this macro?

Time Delay of RS485 datastream and analog output?

Difference between PNP and Relais Output?

How can I change the parameters of a functional block (i.e. BLINK, TON, TOFF, TP) from the front panel of the PR200 or through a variable in akYtec ALP?

What is the maximum load capacity of the inputs and outputs?

How to change analog input between Resistance, Voltage (R, U, I)?

Can I expand the number of inputs/outputs of the PR200?

Can the PR200 be used in a Modbus network as a slave?

How can I connect an expansion module of the Mx110 series to the PR200?

Can I use the PR devices to control and monitor the current of my PV system?

What is the maximum permissible frequency that a digital input of the PR200 can handle in case of using this input to read an impulse signal?

Loss of data. Do you lose the ALP program when you change the battery?

Are the relay outputs of the PR200 suitable to control a power contactor?

Compatibility with HMI? What does a HMI need to be working with the PR-devices?

Can the integrated voltage source of a PR200-230.X.X be used for feeding an input module Mx110-24.X? What about feeding an ITP16 or ITP14?

What happens to my variables when we have a power failure? Is the program persistent?

What is the minimum voltage and current needed for proper operation of an input of the PR200?

Can the PR-Devices be used as a PID-Controller?

How many variables can the PR200 handle as Modbus Slave?

Can I control a pumping System with the PR-devices?

How many Modbus Slaves can the PR200 control as Master Device?

What steps do I have to take to calibrate the PR-devices when i have uncertanties in the measurement?

I have a PR200 with 2 RS485 interfaces. Is it possible to read some data from a Modbus Slave Sensor over one RS485 and make them available on the other?

How to display negative values on the display?

I have set Slot 1 to Master on the Device Configuration dialog box in akYtec ALP but it doesn’t work properly. What should I check?

How does the Modbus register work and why is it in hexadecimal? (3x0000 to 3xFFFF)

In what numeral system should be written the register address, decimal or hexadecimal?

I have connected a slave device to the PR200. I can read INT variables but I am having problems with REAL variables. I want to show a value on the display but it shows a different value that doesn’t make sense. What should I check?

How should I configure an analog input of the PR200?

The button 'Transfer application to device' is not available. What should I do?

How many PRM modules does the PR supports?
