I have a problem right now. Before i was able to connect to the plc (s7-312c cpu) using PC Adapter USB-MPI/DP connector. But all of a sudden there was a power interruption while im in monitor mode. Then i tried to connect again the pc to plc, this time online connection is not possible anymore. What could be cause of this. please help..
