The Smart Logic Control (SLC) is essentially a
sequence of user defined actions (see par. 13-52
[x]) executed by the SLC when the associated
user defined event (see par. 13-51 [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 event / actions :
Starting and stopping the
Starting and stopping the SLC can be done by
selecting "On [1]" or "Off [0]" in par. 13-00. 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). The SLC stops when the Stop Event
