I have a SLC 5/03 with an MCM-1350. Both ports are Modbus Masters. Port 1 is communicating fine with a Modbus device. Port 2 is connected rs-485 to a Kohler Decision Maker 550. We can not establish communication with this device. I have tried different baud rates, parity and stop bit settings. Kohler is basically giving me the run around - no one there has experience connecting Modbus. Any ideas?
