Smart Logic Control (SLC) is essentially a sequence of user
defined actions (see par. 13-52 SL Controller Action [x])
executed by the SLC when the associated user defined event
(see par. 13-51 SL Controller Event [x]) is evaluated as TRUE by
the SLC. Events and actions are each numbered and linked
together in pairs. This means that when event [0] is fulfilled
(attains the value TRUE), action [0] is executed. After this, the
conditions of event [1] will be evaluated and if evaluated TRUE,
action [1] will be executed and so on. Only one event will be
evaluated at any time. If an event is evaluated as FALSE,
nothing happens (in the SLC) during the current scan interval
and no other events will be evaluated. This means that when
the SLC starts, it evaluates event [0] (and only event [0]) each
scan interval. Only when event [0] is evaluated TRUE, will the
SLC execute action [0] and start evaluating event [1]. It is
possible to programme from 1 to 20 events and actions.
When the last event / action has been executed, the sequence
starts over again from event [0] / action [0]. The illustration
shows an example with three event / actions:
Starting and stopping the SLC:
Starting and stopping the SLC can be done by selecting On [1]
or Off [0] in par. 13-00 SL Controller Mode. The SLC always starts
in state 0 (where it evaluates event [0]). The SLC starts when
the Start Event (defined in par. 13-01 Start Event) is evaluated
as TRUE (provided that On [1] is selected in par. 13-00 SL
Controller Mode). The SLC stops when the Stop Event
(par. 13-02 Stop Event) is TRUE. Par. 13-03 Reset SLC resets all
SLC parameters and starts programming from scratch.
3.13.2 13-0* SLC Settings
Use the SLC settings to activate, deactivate and reset the
Smart Logic Control sequence. The logic functions and
comparators are always running in the background, which
opens for separate control of digital inputs and outputs. .
13-00 SL Controller Mode
Option: Function:
[0] Off Disables the Smart Logic Controller.
[1] On Enables the Smart Logic Controller.
13-01 Start Event
Option: Function:
Select the boolean (TRUE or FALSE)
input to activate Smart Logic Control.
[0]
* False Enters the fixed value of FALSE in the
logic rule.
[1] True Enters the fixed value TRUE in the logic
rule.
