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.
MonitoringTime TIME Depends on data
type.
T#0ms A constant.
It gives the maximum response time for the connected,
