I fought the Prosoft battle with both FBM224s and FBM230s. I found that I needed to add an RTS On and/or RTS Off delay (usually around 15-20mS) to the port configuration in the Prosoft configuration file. The various delay and configuration options in the FBM never seemed to help, the change had to be made in the Prosoft card. Good Luck! -Dan -----Original Message----- From: foxboro-bounce@xxxxxxxxxxxxx [mailto:foxboro-bounce@xxxxxxxxxxxxx] On Behalf Of c.a.wolfschlag@xxxxxxxxxxxxxx Sent: Friday, January 20, 2012 7:55 AM To: foxboro@xxxxxxxxxxxxx Subject: [foxboro] Prosoft Card 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?
