4.12 Parameters: 13-** Smart Logic Control
Smart logic control (SLC) is a sequence of user-dened
actions (see parameter 13-52 SL Controller Action) executed
by the SLC when the associated user-dened 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
illustrated:

Illustration 4.36 Smart Logic Control (SLC)
Events and actions are each numbered and linked in pairs
(states). This means that when the 1
st
event is fullled
(becomes true), the 1
st
action is executed. After this, the
conditions of the 2
nd
event are evaluated and if evaluated
true, the 2
nd
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 1
st
event (and
only the 1
st
event) in each scan interval. Only when the 1
st
event is evaluated true, the SLC executes the 1
st
action and
starts evaluating the 2
nd
event. It is possible to program 1–
20 events and actions.
When the last event/action has been executed, the
sequence starts over again from the 1
st
event/action.
Illustration 4.37 shows an example with 3 events/actions:

Illustration 4.37 Events and Actions
Starting and stopping the SLC
Start and stop the SLC by selecting [1] On or [0]
O 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 (dened 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.
Parameter 13-03 Reset SLC resets all SLC parameters and
starts programming from scratch.
NOTICE
SLC is only active in auto-on mode, not hand-on mode.
