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.
[2] Greater Than Inverse logic of [0] Less Than (<).
(>)
13-12 Comparator Value
Range: Function:
0 [-9999 - Enter the trigger level for the variable that is
*
9999 ] 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

Programming Guide
when started by an action (for example [29] Start timer 1)
until the timer value entered in this parameter has elapsed.
Function:
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.

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:
[0] False

Function:
[0 - 3600 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.

Logic Rule Boolean 3
Function:
Select the first boolean (TRUE or
FALSE) input for the selected logic
rule. See parameter 13-01 Start Event
([0]-[61]) and parameter 13-02 Stop
Event ([70]-[74]) for further
description.
