1)
DCP is used by PROFINET to determine PROFINET devices and allow basic settings. Therefore this function is only
available on the CU320-2 DP if the CBE20 Option Board is inserted.
Further information can be found in the SINAMICS S120 Function Manual "Communication".
Any individual behaviors of the LED OPT are described for the respective Option Board.
