4.10.4 13-2* Timers
Use the timer results to define an event (13-51 SL Controller
Action) or as boolean input in a logic rule (13-40 Logic Rule
Boolean 1, 13-42 Logic Rule Boolean 2 or 13-44 Logic Rule
Boolean 3).
When timer value has elapsed timer changes state from
False to True.

Function:
Select operator to be used in comparison.
Result of evaluation is True if variable
selected in 13-10 Comparator Operand is
smaller than fixed value in 13-12
Comparator Value. Result is False if variable
selected in 13-10 Comparator Operand is
greater than fixed value in 13-12
Comparator Value.
Result of evaluation is True if variable
selected in 13-10 Comparator Operand is
approximately equal to fixed value in 13-12
Comparator Value.

4.10.5 13-4* Logic Rules
Combine up to three boolean inputs (TRUE/FALSE inputs)
from timers, comtors, digital inputs, status bits and events
using the logical operators AND, OR, and NOT. Select
boolean inputs for the calculation in 13-40 Logic Rule
Boolean 1, 13-42 Logic Rule Boolean 2 and 13-44 Logic Rule
Boolean 3. Define the operators used to logically combine
the selected inputs in 13-41 Logic Rule Operator 1 and
13-43 Logic Rule Operator 2.

Priority of calculation
The results of 13-40 Logic Rule Boolean 1, 13-41 Logic Rule
Operator 1 and 13-42 Logic Rule Boolean 2 are calculated
first. The outcome (TRUE/FALSE) of this calculation is
combined with the settings of 13-43 Logic Rule Operator 2
and 13-44 Logic Rule Boolean 3, yielding the final result
(TRUE/FALSE) of the logic rule.
