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].
[5] TRUE longer
than..
[6] FALSE
longer
than..
[7] TRUE
shorter
than..
[8] FALSE

13-12 Comparator Value
Array [6]
Range: Function:
Size related
*
[-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.
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.
13-20 SL Controller Timer
Range: Function:
Application
dependent
*
[Application
dependant] 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.
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: Function:
[0]
*
False Select the first boolean (TRUE or
FALSE) input for the selected logic
rule.
