CompactLogix or PV+ Interface to Panasonic FP-Sigma PLC

[pcmccartney1 141]

Does anyone have experience or pointers to interface an L45 or PV+1000 (via kepwareserver) to a Panasonic FP-Sigma Series PLC with a Web Server Module? Talking to Panasonic, they state that the Web Server Module does not support Ethernet IP, but rather Modbus TCP (RTU, ASCII) or TCP/IP. I'm hesitant to try the kepwareserver via PV+, since I'll already have a driver running to interface a 2D barcode scanner attached via USB. Need to send a few digital signals to start cycle, run mode, reset alarms, change or select recipe. Also need to take back digital signals for alarm or fault condition, cycle in progress. Hardwired I/O is possible (therefore no comms needed) but out of spares with no room to add any modules. Any ideas would be appreciated!
