viralpatel Posts: 523 Rating: (32)	i think you s7 program does't include OB for communication. so, without cold restart it will not re establish communication with profibus slave node. so check s7 logic viral patel

king_1985 Posts: 109 Rating: (11)	My OEM vendor said the same that OB is already there thats why CPU was not in STOP mode but I thought there is another OB required so that I dont need Cold Restart in future in such case.. Thanks for help..
