Parameter Description
Discrepancy time (pair 1) The discrepancy time defines how long the two inputs can con‐
t
inue to have discrepant values after a change in either of the
input signals without this being regarded as an error.
0 … 30 s
If set to 0, discrepancy monitoring is deactivated.
The effective value is the input value rounded up to the next
multiple of the logic execution time. The effective discrepancy time
must be = 0 or ≥ the logic execution time.
Discrepancy time (pair 1)
Synchronization time
T
he synchronization time is the amount of time for which the input pairs 1 and 2 are
allowed to have different values.
Fixed value: 500 ms in accordance with EN 574
The synchronization time evaluates the relationship between the two dual-channel
evaluation functions. By contrast, the discrepancy time relates to one pair of inputs for
one dual-channel evaluation function.
Sequence monitoring
T
he Enable output is set to 1 if both input pairs were inactive at the same time for at
least the logic execution time before being activated.
If the Enable output = 1 and then at least one input of an input pair becomes inactive,
then the Enable output = 0.
