Timers (Menu Index 8.4.4)
7.8.2.5
Use the timer results to define an event (P 8.4.6.1 Event) or as boolean input in a logic rule (P 8.4.5.1 Logic Rule Boolean 1, P 8.4.5.3 Logic
Rule Boolean 2, or P 8.4.5.5 Logic Rule Boolean 3).
When timer value has elapsed timer changes state from False to True.
P 8.4.4.1 Timer
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 P 8.4.6.2 Action [29–31] and P 8.4.6.2 Action [70–74] Start timer X) and until the timer value has elapsed. This is an array parameter
containing timers 0–7.

0

Logic Rules (Menu Index 8.4.5)
7.8.2.6
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 P 8.4.5.1 Logic Rule Boolean 1, P 8.4.5.3 Logic Rule Boolean 2,
and P 8.4.5.5 Logic Rule Boolean 3. Define the operators used to logically combine the selected inputs in P 8.4.5.2 Logic Rule Operator 1
and P 8.4.5.4 Logic Rule Operator 2.

Priority of calculation
The results of P 8.4.5.1 Logic Rule Boolean 1, P 8.4.5.2 Logic Rule Operator 1, and P 8.4.5.3 Logic Rule Boolean 2 are calculated first.
The outcome (TRUE/FALSE) of this calculation is combined with the settings of P 8.4.5.4 Logic Rule Operator 2 and P 8.4.5.5 Logic Rule
Boolean 3, yielding the final result (TRUE/FALSE) of the logic rule.
P 8.4.5.1 Logic Rule Boolean 1
Select the 1st boolean (TRUE or FALSE) input for the selected logic rule. This is an array parameter containing logical rules 0–5.
Default value:
0
Parameter
1340
number:
Data type:
enum
The following are the selections for the parameter.
