3.13.1 13-** Prog. Features Prog. Features
Smart Logic Control (SLC) is essentially a sequence of user
defined actions (see
[x]) executed
by the SLC when the associated user defined
event
(see
[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 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
. The SLC always starts
in state 0 (where it evaluates
event
[0]). The SLC starts when
the Start Event (defined in
) is evaluated as
TRUE (provided that
On
[1] is selected in
). The SLC stops when the
Stop Event
is TRUE.
resets all SLC parameters and starts
programming from scratch.
3.13.2 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. .
13-00 SL Controller Mode
Option:
Function:
[0]
Off

On
Enables the Smart Logic Controller.
13-01 Start Event
Option:
Function:
Select the boolean (TRUE or FALSE)
input to activate Smart Logic Control.
