13-11 Comparator Operator
Option:
Function:
Select the operator to be used in the
comparison. This is an array parameter
containing comparator operators 0 to 5.
[0] Less Than (<)
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
.
[1]
*
Approx.Equal
(~)
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
.

13-12 Comparator Value
Range:
Function:
0
*
[-9999 -
9999 ]
Enter the trigger level for the variable that is
monitored by this comparator. This is an
array parameter containing comparator
values 0 to 5.
4.12.3 13-2* Timers
Use the result (true or false) from timers directly to define
an event (see
parameter 13-51 SL Controller Event
), or as
boolean input in a logic rule (see
parameter 13-40 Logic
Rule Boolean 1
,
parameter 13-42 Logic Rule Boolean 2
, or
parameter 13-44 Logic Rule Boolean 3
). A timer is only false
when started by an action (for example
[29] Start timer 1
)
until the timer value entered in this parameter has 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
s]
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.
[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
parameter 13-40 Logic
Rule Boolean 1
,
parameter 13-42 Logic Rule Boolean 2
, and
parameter 13-44 Logic Rule Boolean 3
. Define the operators
used to logically combine the selected inputs in
parameter 13-41 Logic Rule Operator 1
and
parameter 13-43 Logic Rule Operator 2
.

Priority of calculation
The results of
parameter 13-40 Logic Rule Boolean 1
,
parameter 13-41 Logic Rule Operator 1
, and
parameter 13-42 Logic Rule Boolean 2
are calculated first.
The outcome (true/false) of this calculation is combined
with the settings of
parameter 13-43 Logic Rule Operator 2
and
parameter 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
(
[0]-[61]
) and
(
[70]-[74]
) for further
description.
