There are a number of approaches available, but it would help to know a little about your I/A Series system, e.g., Version (see /usr/fox/sp/lastinst/SYSLVL first line) and control types (any CP60s or xCP270s?). The options are: * V6/7 style solutions: o DI30s - Serial interface to DH or DH+ o Modbus FBM (FBM 224) - Serial modbus interface used with CP60 at V6.5.1 or later (requires a Modbus card in the PLC) o AW-Integrator for A-B o AW-Integrator with OPC DA Client I/O Gate * V8 style solutions o Modbus Serial RTU Master FBM 230/231 - Serial Modbus I/F for use with CP270s o Modbus TCP/IP FBM 232/233 - Ethernet Modbus TCP/IP I/F for use with CP270s o OPC DA Client FBM 232/233 - OPC to the AB PLC Hope this helps.

I have to integrate the two for combustion control & burner management = on a steam turbine generator unit. The combustion controls would be replaced with the I/A system but the = budget does not permit the replacement of the PLC based BMS. Hence I'm seeking the best way to interface the two systems.
