Function of the F-DO

Description
The failsafe digital output (F-DO) comprises 2 digital outputs plus one digital input that
checks the switching state for forced checking procedure (test stop). The 1st digital output
switches 24 V DC, and the 2nd switches M of the X130 (CU310-2) voltage supply.
The status of each F-DO can be read at parameter r10052. The status of the associated
DI22 can be read using parameter r0722.22.
The actuator connected to the F-DO can also be tested under specific conditions as part of
forced checking procedure (test stop). See Section "Forced checking procedure (test stop) of
the CU310-2 (Page 306)".
