I have a system which consist of five S7 PLC talking to each other via MPI ports. I use function X-PUT and X-GET to do the job. The problem is that after a power failure, there was two PLC which has communication failure between them. Others was okay. Then I reset (off/on) the
PLC which has the X-PUT & X-GET function. After that the Comms was back to normal.
Any one out there that can help to explain why and any solution to prevent future such occurances.
Thanks
