13-11 Comparator Operator
Array [6]
Option: Function:
mately equal to the xed value in
parameter 13-12 Comparator Value.

13-12 Comparator Value
Array [6]
Range: Function:
Size
related*
[-100000 -
100000 ]
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
dene 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 programme
timer 0, select index 1 to programme timer 1, and so on.
13-20 SL Controller Timer
Array [3]
Range: Function:
Size
related*
[ 0 -
0 ]
Enter the value to dene the duration of
the FALSE output from the programmed
timer. A timer is only FALSE if it is started
by an action (for example [29] Start timer
1) and until the given timer value has
elapsed.
3.13.5 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.
Dene 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
rst.
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
nal
result (TRUE/FALSE) of the logic rule.
13-40 Logic Rule Boolean 1
Array [6]
Option: Function:
[0] False Enters the xed value of FALSE in the
logic rule.
[1] True Enters the xed value TRUE in the logic
rule.
