3.13.3 13-1* Comparators
Comparators are used for comparing continuous variables (i.e. output frequency, output current, analog input etc.) to fixed preset values. In addition,
there are digital values that will be compared to fixed time values. See explanation in par. 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.
