Comparator running time
Comparator running times are time counters that
add up continuously for a set comparator output.
This means that if the condition of the compara-
tor is fulfilled and the lead time has expired, the
counter increases by the corresponding amount
of time - the minimum initialization time is not
considered here!
Comparator with limit violation set
·The set limit value is compared with the mea-
sured value.
·If there is a limit violation for at least the dura-
tion of the lead time, the comparator result is
changed.
·The result is retained at least for the duration of
the minimum initialization time and at most for
the duration of the limit violation. If there is no
longer a limit violation and the minimum initializa-
tion time has expired, the result is reset.
