13-11 Comparator Operator
Array [6]
Option: Function:
Select the operator to be used in the
comparison. This is an array parameter
containing comparator operators 0 to 5.
[0] < Select < [0] for the result of the evaluation to
be TRUE, when the variable selected in
13-10 Comparator Operand is smaller than the
fixed value in 13-12 Comparator Value . The
result will be FALSE, if the variable selected in
13-10 Comparator Operand is greater than the
fixed value in 13-12 Comparator Value .
[1]
*
= (equal) Select ≈ [1] for the result of the evaluation to
be TRUE, when the variable selected in
13-10 Comparator Operand is approximately
equal to the fixed value in 13-12 Comparator
Value .
[2] > Select > [2] for the inverse logic of option <
[0].
[5] TRUE longer
than...
[6] FALSE
longer
than...
[7] TRUE
shorter
than...
[8] FALSE
shorter
than...
13-12 Comparator Value
Array [6]
Range: Function:
Application
dependent
*
[-100000.000 -
100000.000 N/A]
Enter the ‘trigger level’ for
the variable that is
monitored by this
comparator. This is an array
parameter containing
comparator values 0 to 5.
3.14.4 13-2* Timers
Use the result (TRUE or FALSE) from timers directly to define
an event (see 13-51 SL Controller Event ), or as Boolean input in
a logic rule (see 13-40 Logic Rule Boolean 1 , 13-42 Logic Rule
Boolean 2 or 13-44 Logic Rule Boolean 3 ). 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
Range: Function:
Application
dependent
*
[Application
dependant]
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.
