13-11 Comparator Operator
Array [4]
Select operator to be used in comparison.
[0] Less Than < Result of evaluation is
True if variable selected in par. 13-10 is
smaller than fixed value in par. 13-12. Result is
False if variable
selected in par. 13-10 is greater than fixed value in par. 13-12.
[1]
*
Approximately equals
≈
Result of evaluation is True if variable selected in par. 13-10 is
approximately equal to fixed value in par. 13-12.
[2] Greater Than > Inverse logic of option [0].
13-12 Comparator Value
Array [4]
0.0
*
[-9999 - 9999] Enter “trigger level” for variable monitored by this comparator.
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
False to True .
13-20 SL Controller Timer
Array [3]
0.0 s
*
[0.0 - 3600 s] Enter value to define duration of the False output from pro-
grammed timer. A timer is only
False if it is started by an action
and until the given timer value has elapsed.
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.
13-40 Logic Rule Boolean 1
Array [4]
Select first boolean input for selected logic rule.
[0]
*
False Enters False in logic rule.
[1] True Enters
True in logic rule.
