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 (states). 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 start programming from scratch.

3.14.2 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. .
