Parameter Descriptions
13-11 Comparator Operator
Array [6]
Option: Function:
Select the operator to be used in the
comparison. This is an array parameter
containing comparator operators 0 to 5.
[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.
[2] > Select > [2] for the inverse logic of option <
[0].

3.14.4 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. 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.

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.

3.14.5 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.
13-40 Logic Rule Boolean 1
Array [6]
Option:
[0] False Select the first boolean (TRUE or
*
FALSE) input for the selected logic
rule.

Function:
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.
