Hi
I want to read and write some values between PFC200 and a slave device Modbus RTU (RS485).
I've added all Modbus Libraries and PFC200 Libraries to my project.
I've inserted Modbus_com, Modbus_Master_COM_Port and Modbus_Slave_COM_Port into Devices tree.
but now.. how can I change serial port using WAGO PFC200 on MODBUS RTU from RS232 TO RS485?

Thanks in advance
