Safety Functions.
The initial release of the new ET 200pro FC-2 includes only basic safety functions.
Safe Torque Off (STO)
This differs from the old ET 200PRO 6SL3235-0TE21-1SB0 (With safety functions)
which had the following safety functions:
"Safe Torque Off" (STO)
"Safe Stop 1" (SS1)

Controlling the safety functions
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-
related input.

Additional information on the ET 200pro system and the F-Switch module is
available in the "SIMATIC distributed ET 200pro I/O system - Fail-Safe Modules"
