When this parameter is active, the function is processed in the
safety logic.
When the parameter is deactivated, the set substitute value is
made available at the output Q.
"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
Use these parameters to determine the input type of the function:
Single-channel (NO)
•
IN1 is monitored for "1", i.e. the function output Q is
deactivated when there is a "0" signal.
Two-channel (NONO)
•
IN1 and IN2 are monitored for "1", i.e. the function output Q is
deactivated when there is at least one "0" signal.
Select the input to be processed by the function.
