10.14 Comparator
Two comparator groups (comparator 1 and 2)
each with 3 comparators (A - C) are available for
monitoring limit values.
The results of comparators A to C can be linked
with “
AND ” or “ OR ”.
The comparators can be configured exclusively
via the GridVis
®
software in the “ Comparator ”
configuration area.

Comparator with limit violation set
·The set limit value is compared with the measured
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 initialization time
has expired, the result is reset.
You can read the result of the comparators via
the GridVis software. The corresponding Modbus
addresses can be found in the Modbus address list
at www.janitza.de
