I have a PLC stopping and generating this major fault once a week, or so. Does the "A" represent slot 10 according to the I/O configuration? If that is the case, it is the RIO scanner. If it is the 10th slot (9 in the config) then it is a 1746sc-OAP8I. In either case...what should I be looking for? This is shutting down a small 24 hour/day plant at random intervals. Thanks!!
