4.10.4. 13-2* Timers

Use the timer results to define an event (par. 13-51) or as boolean input in a logic rule (par. 13-40,
13-42 or 13-44).
When timer value has elapsed timer changes state from

4.10.5. 13-4* Logic Rules

Combine up to three boolean inputs (TRUE / FALSE inputs) from timers, comparators, digital in-
puts, status bits and events using the logical operators AND, OR, and NOT. Select boolean inputs
for the calculation in par. 13-40, 13-42, and 13-44. Define the operators used to logically combine
the selected inputs in par. 13-41 and 13-43.
Priority of calculation
The results of par. 13-40, 13-41, and 13-42 are calculated first. The outcome (TRUE / FALSE) of
this calculation is combined with the settings of par. 13-43 and 13-44, yielding the final result
(TRUE / FALSE) of the logic rule.
