I'm having trouble getting a Prosoft card M169-MCM to talk to I/A via a Modbus gateway. The Prosoft card is an upgrade of an existing control panel that was talking modbus to IA via the same Modbus gateway. The new controller is an A-B Compactlogix with the Prosoft card M169-MCM. I have the new Prosoft card set up the same as the old controller: RS-485, 4800 baud, 8 bits, even parity, 1 stop bit & both ports configures as slaves. The old controller was set up as RTU7 on a network of eight different devices and this new controller takes its place. When I connect the Prosoft card to the network it seems to drag down the entire system, and I start getting what appear to be random A & B errors. Any clues as to what is going on? Has anybody had experience with connecting the Prosoft card? Thanks for your inputs. _______________________________________________________________________ This mailing list is neither sponsored nor endorsed by Invensys Process Systems (formerly The Foxboro Company).
