Safety FB Common Input Variables
S_OutControl
SAFEBOOL TRUE or FALSE
FALSE
A variable.
The control signal from the previous safety FB. The sig-
nal from a typical FB from the library (SF_OutControl,
SF_TwoHandControlTypeII, etc.) is used.
FALSE: Disables the safety output (S_EDM_Out).
TRUE: Enables the safety output (S_EDM_Out).
S_EDM1
SAFEBOOL TRUE or FALSE
FALSE
A variable.
The feedback signal from the first connected actuator.
FALSE: The first connected actuator is in switched status.
TRUE: The first connected actuator is in its default status.
S_EDM2
SAFEBOOL TRUE or FALSE
FALSE
A variable.
The feedback signal from the second connected actuator.
If there is only one feedback signal used in the applica-
tion, connect it to both
S_EDM1
and
S_EDM2
.
FALSE: The second connected actuator is in switched
status.
TRUE: The second connected actuator is in its default
status.

T#0ms
A constant.
It gives the maximum response time for the connected,
monitored actuator.
