Hello, Do you have Modbus TCP on your PLC? If so you can connect to the RIO and send Modbus commands to read the analog inputs. The RIO will also accept ASCII based commands over a TCP or UDP connection. You could send the command "MG @AN[1]" and the controller would respond with a ":" and the analog voltage at input 1.
