TIME TO TIME PLC TURN TO STOP MODE & IT WONT GO TO RUN MODE AFTER POWER RECYCLE. IF WE CONNECT PG & CHANGE PLC MODE FROM PG THEN ONLY IT TURNS TO RUN MODE. WHAT WOULD BE THE PROBABLE CAUSE SINCE OUR PROFIBUS NETWORK IS ALSO HEALTHY. IS THERE ANY POSSIBILITY TO CHANGE OPERATING MODE OF PLC FROM HMI, SO THAT THERE IS NO NEED TO CONNECT PG TO PLC. PLEASE GUIDE US AT EARLIEST. PLEASE FIND ATTACHED PLC PROGRAM FOR YOUR REFERENCE. REGARDS, RAHUL

PLEASE GUIDE US AT EARLIEST. PLEASE FIND ATTACHED PLC PROGRAM FOR YOUR REFERENCE REGARDS, RAHUL 1. The PLC program was not attached. 2. Does the plc have diagnostic error routine to capture errors that might allow you to discover what is causing it to stop? 3. The HMI cannot cause the plc to start running. 4. There is a plc configuration option to restart on power up. If that option is used and there is a fuse protecting the plc, you can instruct technicians to pull that fuse, wait a few seconds, then reinsert the fuse. We use fuse holders that rotate the fuse out of the circuit to make that easier. 5. Perhaps details of the plc firmware, portal version, service pack, update # would also help. 6. I have seen several instances of a short term profibus error would cause the plc to go into stop mode. Once the plc went into stop, the profibus error would go away. That makes it difficult to troubleshoot without that diagnostic error routine.
