3.9.4 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 is 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:
0 s [0 -

3600 s]
3.9.5 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 combine the selected inputs logically in
parameter 13-41 Logic Rule Operator 1 and
parameter 13-43 Logic Rule Operator 2.

TR150 and TR170
Function:
Select [2] > for the inverse logic of option
[0] <.
Function:
Enter the trigger level for the variable that is
monitored by this comparator. This
parameter is an array parameter containing
comparator values 0–5.
Function:
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 (see
parameter 13-52 SL Controller Action [29–31] and
parameter 13-52 SL Controller Action [70–74] Start
timer X) and until the timer value has elapsed.
Array parameters contain timers 0–7.

Illustration 3.15 Logic Rules
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
Array [6]
Option: Function:
[0] False Enters the fixed value of false in the logic
*
rule.
[1] True Enters the fixed value true in the logic
rule.
