I have a transport wr21 and a device that communicates using a serial port Modbus RTU Binary protocol (Allen Bradley Prosoft). Can I and how do I configure the serial port to talk with it? The only think I have found to point me in this direction is the Legacy Protocols > Modbus Gateway > Modbus 0.
This will not enable me to set Async Port: 502 (defaults to 246)
There is no specification of RTU Binary for the port
