This is the second video of our video tutorial set.

This video shows you how it is easy to organize communication between the digital display SMI2 and our programmable relay PR200 using Modbus RTU communication protocol.

At first, we configure the display with the help of SMI2 configurator and then connect it to the relay over RS485 interface. In a simple project in akYtec ALP we create a value and download the little application to the PR200. Finally, the value can be transferred to the SMI2.
