How to Program
Select *Do not reset SLC [0] to retain
the programmed settings in all group 13
parameters (13-*).
" 13-1* Comparators
Used for comparing continuous variables (i.e. output
frequency, output current, analog input etc.) with
a fixed preset value. Com parators are evaluated
once in each scan interval. You can use the result
(TRUE or FALSE) directly to define an event (see
par. 13-51), or as Boolean input in a logic rule ( see
par. 13-40, 13-42, or 13-44). All parameters in
this p arameter group are array parameters with
index 0-3. Select index 0 to program Comparator
0, index 1 to program Com parator 1, and so on.

True [1]. enters the fixed value TRUE
in the logic rule.
