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 (de-
fined 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.
