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.

Function:
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.
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.
Select [2] > for the inverse logic of option [0]
<.
Function:
[-100000 - Enter the 'trigger level' for the
variable that is monitored by this
comparator. This is an array
parameter containing comparator
values 0 to 5.

3.12.5 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.

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.
