Function of the F-DO

Fail-safe digital outputs (F-DO) consist of 2 digital outputs and 1 digital input that checks the
switching state for the forced checking procedure (test stop). The 1st digital output switches
the 24 V DC, and the 2nd digital output switches the X514 power supply (TM54F).
The status of each F-DO can be read at parameter r10052. The status of the associated DI
can be read at parameter r10053 (only available for TM54F_SL (TM54F Slave Module)).
The actuator connected to the F-DO can also be tested under specific conditions as part of
the forced checking procedure (test stop). See Section "Forced checking procedure (test
stop) (Page 677)".
