13-12 Comparator Value
Array [6]
Range: Function:
0 N/A* [-100000.000 - 100000.000 N/A] Enter the ‘trigger level’ for the variable that is monitored by this comparator. This is an array pa-
rameter 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
SL Controller Event
), or as Boolean input in a
logic rule
(see par.
13-40
Logic Rule Boolean 1
, par.13-42
Logic Rule Boolean 2
or par.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 an index of 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]
Range: Function:
0 N/A* [0.000 - 360000.000 N/A] 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
Logic Rule Boolean 1 , par.13-42 Logic Rule Boolean 2 and par.13-44 Logic Rule
Boolean 3 . Define the operators used to logically combine the selected inputs in par.13-41 Logic Rule Operator 1 and par.13-43 Logic Rule Operator 2 .
Priority of calculation
The results of par.13-40
Logic Rule Boolean 1
, par.13-41
Logic Rule Operator 1
and par.13-42
Logic Rule Boolean 2
are calculated first. The outcome
(TRUE / FALSE) of this calculation is combined with the settings of par.13-43
Logic Rule Operator 2
and par.13-44
Logic Rule Boolean 3
, yielding the final
result (TRUE / FALSE) of the logic rule.
13-40 Logic Rule Boolean 1
Array [6]
Option: Function:
[0] * FALSE Enters the fixed value of FALSE in the logic rule.
[1] TRUE Enters the fixed value TRUE in the logic rule.
