In this training, you will learn more about how to use the new communication module for easyE4. In the first tutorial, you will see how Modbus RTU devices (using the DG1 variable frequency drive as an example) are processed on the easyE4 control relay via the EASY-COM-RTU-M1 communication module. The second tutorial illustrates how the easyE4 communication module for SmartWire-DT allows you to combine the advantages of this powerful control relay with those of our intelligent wiring system.
