Hi, I need my 2040 to communicate with a PLC using Modbus over RS485 .I have used the Modbus contrib node and configured it to be serial .Defined port as /dev/ttyS2. I have connected to the X30 com.How do i check wheather the port is working .I checked using an oscilloscope but could not get any signal.
