CPU317-2PN / DP constant BF1 is lit.

Semast Posts: 6 Rating: (0)	Hello. CPU317-2PN / DP on it is constantly lit BF1, when you insert the PROFIBUS CONNECTOR with the switch in the ON state of the MPI / DP interface socket, only then the BF1 LED goes out. There is nothing loaded in the CPU (neither the configuration nor the logic), it is empty. Peripheral equipment is not used. Why is BF1 lit, please tell me?
