3.12.3 13-04 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 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.

[0]
<
Select [0] < for the result of the evaluation to be
*
TRUE, when the variable selected in
13-10 Comparator Operand is smaller than the
fixed value in 13-12 Comparator Value. The result
will be FALSE, if the variable selected in
13-10 Comparator Operand is greater than the
fixed value in 13-12 Comparator Value.
[1]
≈ (equal) Select [1] ≈ for the result of the evaluation to be
TRUE, when the variable selected in
13-10 Comparator Operand is approximately equal
to the fixed value in 13-12 Comparator Value.

3.12.4 13-2* Timers
Use the result (TRUE or FALSE) from timers directly to
define an event (see 13-51 SL Controller Event), or as
boolean input in a logic rule (see 13-40 Logic Rule Boolean
1, 13-42 Logic Rule Boolean 2 or 13-44 Logic Rule Boolean 3).
A timer is only FALSE when started by an action (i.e. [29]
Start timer 1) until the timer value entered in this
parameter is elapsed. Then it becomes TRUE again.
All parameters in this parameter group are array
parameters with index 0 to 2. Select index 0 to program
Timer 0, select index 1 to program Timer 1, and so on.
