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 program 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
events/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.
