Hi all, got a nice problem here. Got a fanuc 90-30 in a plastic molding machine that got wrecked by a 600V surge though a faulty SSR. We replaced a temperature control module, a motion control and and input card that were damaged, and now, after restoring the cpu program from a backup, and clearing the fault table, I was able to get it in run mode, no fault. My problem is, I can communicate using the CPU serial port, but i'm unable to do so using the Power supply serial port. It's a major problem, because the HMI use both port to communicate with the PLC. I tried switching for a spare power supply, without any result. Might the CPU be faulty even if it seem to run ? Or maybe the backplate ?
Thanks.
Thanks.
