3.14 Parameters: 13-** Smart Logic Control
3.14.1 Prog. Features
Smart Logic Control (SLC) is essentially a sequence of user-
defined actions (see
13-52 SL Controller Action
[x]) executed
by the SLC when the associated user-defined
event
(see
13-51 SL Controller Event
[x]) is evaluated as TRUE by the
SLC .
The condition for an event can be a particular status or
that the output from a logic rule or a comparator operand
becomes TRUE. That will lead to an associated action as
illustrated:

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 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
figure 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
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
13-01 Start Event
) is evaluated as TRUE (provided that
On
[1] is selected in
13-00 SL Controller Mode
). The SLC stops
when the
Stop Event
(
13-02 Stop Event
) is TRUE.
13-03 Reset
SLC
resets all SLC parameters and start programming from
scratch.
3.14.2 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:
