[1] for the result of the evaluation to be TRUE, when
the variable selected in par. 13-10 is approximately equal to the
fixed value in par. 13-12.

13-12 Comparator Value
Array [6]
0.000
*
[-100000.000 -
100000.000]
Enter the ‘trigger level’ for the variable that is monitored by this
comparator. This is an array parameter containing comparator
values 0 to 5.
2.14.4. 13-2* Timers
This parameter group consists of timer parameters.
Use the result (TRUE or FALSE) from
timers
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). A timer is only FALSE when started
by an action (i.e. Start timer 1 [29]) 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.
13-20 SL Controller Timer
Array [8]
0.00s
*
[00:00:00.000 -
99:59:59.999]
Enter the value to define the duration of the FALSE output from
the programmed timer. A timer is only FALSE if it is started by
an action (i.e.
Start timer 1
[29]) and until the given timer value
has elapsed.
2.14.5. 13-4* Logic Rules
Combine up to three boolean inputs (TRUE / FALSE inputs) from timers, comparators, digital in-
puts, status bits and events using the logical operators AND, OR, and NOT. Select boolean inputs
for the calculation in par. 13-40, 13-42, and 13-44. Define the operators used to logically combine
the selected inputs in par. 13-41 and 13-43.
Priority of calculation
The results of par. 13-40, 13-41, and 13-42 are calculated first. The outcome (TRUE / FALSE) of
this calculation is combined with the settings of par. 13-43 and 13-44, yielding the final result
(TRUE / FALSE) of the logic rule.
