3.14.3 13-1* Comparators
Comparators are used for comparing continuous variables
(i.e. output frequency, output current, analog input etc.) to
fixed preset values.
Par. 13-10
Comparator Operand
Par. 13-12
Comparator Value
In addition, there are digital values that will be compared to
fixed time values. See explanation in 13-10 Comparator
Operand. Comparators are evaluated once in each scan
interval. Use the result (TRUE or FALSE) directly. All
parameters in this parameter group are array parameters
with index 0 to 5. Select index 0 to programme Comparator
0, select index 1 to programme Comparator 1, and so on.

TRUE longer than.
. . .
. . .
Function:
Choice [1] to [31] are variables which will
be compared based on their values.
Choice [50] to [186] are digital values
(TRUE/FALSE) where the comparison is
based on the amount of time during
which they are set to TRUE or FALSE,
respectively. See 13-11 Comparator
Operator.
Select the variable to be monitored by
the comparator.
DISABLED [0] The comparator is disabled.
Reference [1] The resulting remote
reference (not local) as a percentage.
