4.12.3 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]

Function:
Function:
Select the operator to be used in the
comparison. This is an array parameter
containing comparator operators 0 to 5.
The result of the evaluation is TRUE, when
the variable selected in
parameter 13-10 Comparator Operand is
smaller than the fixed value in
parameter 13-12 Comparator Value. The
result is FALSE, if the variable selected in
parameter 13-10 Comparator Operand is
greater than the fixed value in
parameter 13-12 Comparator Value.
The result of the evaluation is TRUE, when
the variable speed selected in
parameter 13-10 Comparator Operand is
approximately equal to the fixed value in
parameter 13-12 Comparator Value.
Inverse logic of [0] Less Than (<).
Function:
Enter the "trigger level" for the variable that
is monitored by this comparator. This is an
array parameter containing comparator
values 0 to 5.

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.
13-20 SL Controller Timer
Range: Function:
0 s [0 - 3600 Enter the value to define the duration of the
*
s] FALSE output from the programmed timer. A
timer is only FALSE if it is started by an action
(i.e. [29] Start timer 1 and until the given timer
value has elapsed.

4.12.4 13-4* Logic Rules

Combine up to 3 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.
13-40 Logic Rule Boolean 1
Option: Function:
Select the first boolean (TRUE or
FALSE) input for the selected logic
rule. See parameter 13-01 Start Event
([0]-[61]) and parameter 13-02 Stop
Event ([70]-[74]) for further
description.
