Have trouble getting modbus comms from a Omni Flow Computer 6000 through a Modicon multiplexer BM85 to a Modicon Quantum PLC with Modbus Plus on the PLC. Already have modbus data coming from a Allen Bradley PLC and HMI to the Modicon with no troubles. These are slave devices though and i need to be a master. I can talk to the Modicon PLC through the Multiplexer to do any programming to the PLC. Any ideas?
