Select operator to be used in comparison.
[0]
Less Than <
Result of evaluation is
True
if variable
selected in
13-10 Comparator Operand
is
smaller than fixed value in
13-12
Comparator Value
. Result is
False
if variable
selected in
13-10 Comparator Operand
is
greater than fixed value in
13-12
Comparator Value
.
[1]

Approxi-
mately equals
≈
Result of evaluation is
True
if variable
selected in
13-10 Comparator Operand
is
approximately equal to fixed value in
13-12
Comparator Value
.
[2]

13-12 Comparator Value
Array [4]
Range:
Function:
0.0
*
[-9999-9999] Enter “trigger level” for variable monitored
by this comparator.
4.10.4 13-2* Timers
Use the timer results to define an event (
13-51 SL Controller
Action
) or as boolean input in a logic rule (
13-40 Logic Rule
Boolean 1
,
13-42 Logic Rule Boolean 2
or
13-44 Logic Rule
Boolean 3
).
When timer value has elapsed timer changes state from
False
to
True
.
13-20 SLC Controller Timer
Array [3]
Range:
Function:
0.0 s
*
[0.0-3600 s] Enter value to define duration of the
False
output from programmed timer. A timer is
only
False
if it is started by an action and
until the given timer value has elapsed.
4.10.5 13-4* Logic Rules
Combine up to three boolean inputs (TRUE/FALSE inputs)
from timers, comtors, 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 [4]
Option:
Function:
Select first boolean input for selected
logic rule.
[0]
*
False
Enters
False
in logic rule.
[1]
True
Enters
True
in logic rule.
