Hi, I have a problem regarding on how to configure modbus tcp in Ecostruxure Automation Expert. In my project, I poll data from relay. At relay, the data communication used is RS485, and i convert it to modbus tcp via converter and connect it to Modicon M251. I do not know how to configure the modbus tcp in Ecostruxure Automation Expert. Here attached the relay data for your reference.

Hi Alif,
Please refer to the video link below for configuring the Modbus Master TCP. For the Slave configuration, you will need to select the Slave library; all other steps remain the same.

Hi Aliffdani, I though that M251d had a serial port and so why using a converter and not use directly Modbus RTU ?
As your M251d is a client and your relay is a server you need the library Standard.IOModbus, on HW Configuration Editor add your Bus Master Standard.IO.Modbus.MODBUSSERIAL. On property, you can configure communication speed, parity etc and add a modbus coupler and HW CAT to read coil register etc ...
Please refer to mentioned documentation.
