This CPU also communicates via 512-5BC12 to a 928B (call this PLCB). There is a 3rd CPU 928B (PLC C) on the process, which is under-utilised. I would like to move the program from the CPU921 (PLC A) to the under-utilised 928B (PLC C). This would allow us to update the old digital IO to S7 and connect it via IM 308C in the 928B (PLC C). I realise there would be some work in rewriting the serial interface currently between 921 (PLC A)& 928B (PLC B) to the under-utilised 928B (PLC C) - 928B (PLC B) My question - is it possible for the 928B to connect to the original digital IO using the existing interface modules as an intermediate step? thanks, Fiona
