13-11 Comparator Operator
Array [6]
For par. 13-10 containing values from [0] to [31] the following is valid:
Select the operator to be used in the comparison.
[0] < Select < [0] for the result of the evaluation to be TRUE, when the variable selected in par. 13-10 is smaller than
the fixed value in par. 13-12. The result will be FALSE, if the variable selected in par. 13-10 is greater than the
fixed value in par. 13-12.
[1]
*
≈ Select ≈ [1] for the result of the evaluation to be TRUE, when the variable selected in par. 13-10 is approximately
equal to the fixed value in par. 13-12.
[2] > Select > [2] for the inverse logic of option < [0].
13-12 Comparator Value
Array [6]
0.000
*
[-100000.000 -
100000.000]
Enter the ‘trigger level’ for the variable that is monitored by this comparator. This is an array parameter containing
comparator values 0 to 5.
3.13.4. 13-2* Timers
This parameter group consists of timer parameters.
Use the result (TRUE or FALSE) from
timers
directly to define an
event
(see par. 13-51), or as boolean input in a
logic rule
(see par. 13-40, 13-42 or
13-44). A timer is only FALSE when started by an action (i.e. Start timer 1 [29]) 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 to 2. Select index 0 to program Timer 0, select index 1 to program Timer 1,
and so on.
13-20 SL Controller Timer
Array [3]
0.00 s
*
[0.00 - 360000.00 s]
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 (i.e.
Start timer 1
[29]) and until the given timer value has elapsed.
3.13.5. 13-4* Logic Rules
Combine up to three 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 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.
