Siemens SINAMICS G120 Function Manual page 43

The SIMATIC ET 200pro FC-2 converter does not have its own PROFIsafe interface. The
central F-CPU controls the safety functions of the ET 200pro FC-2 via a "High Feature"
interface module and the PROFIsafe "F-Switch" module.
The F-Switch module switches the "F0" and "F1 rails" in the backplane bus of the ET-200pro
system. The inverter evaluates the F0 rail using an internal, safety input.

Additional information on the ET 200pro system and the F-Switch module is available in the
"SIMATIC distributed ET 200pro I/O system" Operating instructions. See also Section:
Manuals for your inverter (Page 334).
Additional possibilities of installing the F-Switch module are listed in the Internet: FAQ
