4.12 Parameters: 13-** Smart Logic Control
Smart logic control (SLC) is a sequence of user-defined
actions (see
parameter 13-52 SL Controller Action
) executed
by the SLC when the associated user-defined event (see
parameter 13-51 SL Controller Event
) 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 leads to an associated action as

Illustration 4.22 Smart Logic Control (SLC)
Events and actions are each numbered and linked in pairs
(states). This means that when the first event is fulfilled
(becomes true), the first action is executed. After this, the
conditions of the second event are evaluated and if
evaluated true, the second action is executed and so on.
Only 1 event is 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 are evaluated.
This means that when the SLC starts, it evaluates the first
event (and only the first event) in each scan interval. Only
when the first event is evaluated true, the SLC executes the
first action and starts evaluating the second event. 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 the first event/action.

Illustration 4.23 Events and Actions
Starting and stopping the SLC
Start and stop the SLC by selecting
[1] On
or
[0] Off
in
parameter 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
parameter 13-01 Start
Event
) is evaluated as true (provided that
[1] On
is selected
in
parameter 13-00 SL Controller Mode
). The SLC stops when
the
stop event
(
parameter 13-02 Stop Event
) is true.
resets all SLC parameters and
starts programming from scratch.
NOTICE
SLC is only active in auto on mode, not hand on mode.
4.12.1 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.
