13-11 Comparator Operator
Default value: [1] Approx.Equal (~)
Conversion index: -
Table 223: Option:
[0]
Less Than (<)
Select [0]< for the result of the evaluation to be True, when the variable selected in parameter 13-10 Com-
parator Operand is smaller than the fixed value in parameter 13-12 Comparator Value. The result is False, if
the variable selected in parameter 13-10 Comparator Operand is greater than the fixed value in parameter
13-12 Comparator Value.
[1]
Approx.Equal
Select [1]≈ for the result of the evaluation to be True, when the variable selected in parameter 13-10 Com-
(~)
parator Operand is approximately equal to the fixed value in parameter 13-12 Comparator Value.
[2]
Greater Than (>)
Select [2]> for the inverse logic of option [0]<.
13-12 Comparator Value
Default value: 0
Conversion index: -3
Enter the trigger level for the variable that is monitored by this comparator. This parameter is an array parameter containing compa-
rator values 0–9.
Table 224: Range:
Min: -9999
4.10.3 13-2* Timers
Use the result (True or False) from timers directly to define an event (see parameter 13-51 SL Controller Event), or as boolean input in
a logic rule (see parameter 13-40 Logic Rule Boolean 1, parameter 13-42 Logic Rule Boolean 2, or parameter 13-44 Logic Rule Boolean 3).
A timer is only False when started by an action (for example [29] Start timer 1) until the timer value entered in this parameter has
elapsed. Then it becomes True again.
All parameters in this parameter group are array parameters with index 0–2. Select index 0 to program timer 0, select index 1 to
program timer 1, and so on.
13-20 SL Controller Timer
Default value: 0 s
Conversion index: -2
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 parameter 13-52 SL Controller Action [29–31] and parameter 13-52 SL Controller Action [70–74] Start timer X) and until the
timer value has elapsed. Array parameters contain timers 0–7.
Table 225: Range:
Min: 0 s
4.10.4 13-4* Logic Rules
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 parameter 13-40 Logic Rule Boolean 1, parameter 13-42 Logic
Rule Boolean 2, and parameter 13-44 Logic Rule Boolean 3. Define the operators used to combine the selected inputs logically in
parameter 13-41 Logic Rule Operator 1 and parameter 13-43 Logic Rule Operator 2.
