● Processing safety-relevant internal and external signals in the safety-relevant
user program (safety program).
See: Safety program of the F-PLC (Page 53)
● Processing status and control signals (SIC/SCC) via the corresponding axis
DB (LBP_Axis1 [DB31] ... LBP_Axis8 [DB38]).
See: PLC user interface (DB3x) (Page 213), SIC/SCC (Page 212)
NC
● Transfers status and control information (SIC/SCC, axis DB) between the F-
PLC and SINAMICS S drive.
● Reads-in safety-relevant messages/signals from the message buffers of the
SINAMICS drive into the NC alarm buffer.
