2.14. Parameters: Smart Logic Control
2.14.1. 13-** Prog. Features
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 (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. 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 (par. 13-02) is TRUE. Par. 13-03 resets all SLC pa-
rameters and start programming from scratch.
