Parameter Description
13-12 Comparator Value
Array [6]
Range: Function:
Size related [-100000 - Enter the trigger level for the
*
100000] variable that is monitored by this
comparator. This is an array
parameter containing comparator
values 0–5.
3.11.4 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 0–2. Select index 0 to program
timer 0, select index 1 to program timer 1, and so on.
13-20 SL Controller Timer
Array [8]
Range: Function:
Size related [ 0 - 0] Enter the value to define the duration of
*
the false output from the programmed
timer.
3.11.5 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. 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.
