Parameter Description
3.13.4 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
3
3
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. 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.

3.13.5 13-4* Logic Rules
Combine up to three boolean inputs (TRUE / FALSE inputs)
from timers, comparators, digital inputs, status bits and
events using the logical operators AND, OR, and NOT.
Select boolean inputs for the calculation in 13-40 Logic Rule
Boolean 1, 13-42 Logic Rule Boolean 2 and 13-44 Logic Rule
Boolean 3. Define the operators used to logically combine
the selected inputs in 13-41 Logic Rule Operator 1 and
13-43 Logic Rule Operator 2.

Logic Rule Boolean 2
Priority of calculation
The results of 13-40 Logic Rule Boolean 1, 13-41 Logic Rule
Operator 1 and 13-42 Logic Rule Boolean 2 are calculated
first. The outcome (TRUE / FALSE) of this calculation is
combined with the settings of 13-43 Logic Rule Operator 2
and 13-44 Logic Rule Boolean 3, yielding the final result
(TRUE / FALSE) of the logic rule.

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.
