4.10.3. 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. 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 pro-
gramme Comparator 1, and so on.
