13-11 Comparator Operator
Array [6]
Option:
Function:
[0]
*
<
Select < [0] for the result of the evaluation to
be TRUE, when the variable selected in
is smaller than the
fixed value in
. The
result will be FALSE, if the variable selected in
is greater than the
fixed value in
.
[1]
≈ (equal)
Select ≈ [1] for the result of the evaluation to
be TRUE, when the variable selected in
is approximately
equal to the fixed value in
.
[2]
>
Select > [2] for the inverse logic of option <
[0].

[-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.
3.13.4 13-2* Timers
Use the result (TRUE or FALSE) from
timers
directly to define
an
event
(see
), or as boolean input in
a
logic rule
(see
or
). 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

and
.
Define the operators used to logically combine the selected
inputs in

Priority of calculation
The results of
and
are calculated first.
The outcome (TRUE / FALSE) of this calculation is combined
with the settings of
and
, yielding the final result (TRUE /
FALSE) of the logic rule.
13-40 Logic Rule Boolean 1
Array [6]
Option:
Function:
[0]
*
False
Enters the fixed value of FALSE in the
logic rule.
[1]
True
Enters the fixed value TRUE in the logic
rule.
