Measured value (Addr. 015)
The measured value indicates the address of
the supervised measured value. The following
values can be assigned:
000 = Comparator inactive.
001 = the comparator result can be written
externally (Modbus RTU).
200 ..
400 = Measured values of measured
value list.
Limit (Addr. 018)
The limit serves a constant of the type LONG.
The limit is compared to the corresponding
measured value.
Minimum time (Addr. 016)
For the duration of the minimum time, the com-
parator result remains active (Addr.389). The
minimum time can be programmed in the range
of 1...900 seconds.
Run up time (Addr. 064)
At least for the duration of the run up time, a
violation of the limit must be active to change
the comparator result.
The run up time can be programmed in the
range of 1...900 seconds.

Operator (Addr. 017)
There are two operators available for the
comparsion of measured value and limit.
Operator =
0
means
higher than (>=)
Operator =
1
means
smaller than (<)
Comparator result (Addr.386)
The result of the comparison of measured value
and limit is the comparator result.
The correspondence is:
0 = No limit violation.
1 = Limit violation.
Data memory (Addr. 500)
Changes of the comparator results can be
stored in the memory (option), as long as profile
4 for the memory (addr. 056) was activated.
Total running time (Addr. 396)
This is the sum of all times, for which the limit
was violated.
Combination (Addr. 044)
Combines the results of the comparators A, B
and C
AND
or
OR
.
Invert result (Addr. 046)
The result of the combination (Addr. 046) can be
inverted or not.
Total combination result (Addr. 389)
The combined comparator results of the com-
parators A, B and C are in the total combination
result.
