Dear Everyone I have one S7-300 CPU314C. It was frequently trip SF. I would say trip every 10 mins. So, I use my laptop to remote diagnosis into the PLC. I got messages from diagnosis buffer "STOP caused by rack failure (OB not loaded or not possible, or no FRB)". I read the event description but quite not understand. Please guide me to solve this problem. Thanks +++ ------------------------------------------------------------------------------------------ |
