Description/parameter value
You can enter a name for the element here.
Consecutive number which is automatically assigned. You can
change the number.
When this parameter is active, the function is processed in the
safety logic.
When this parameter is deactivated, the set substitute value is

"0" or "1" can be assigned to the substitute value when the
element is deactivated.
Substitute value "0" means output Q = 0
substitute value "1" means output Q = 1
Only available with output type "Redundant F output":
"0" or "1" can be assigned to the substitute value when the
