Parameter Description

3.12 Parameters 13-** Smart Logic Control

Smart Logic Control (SLC) is essentially a sequence of user
defined actions (see parameter 13-52 SL Controller Action
[x]) executed by the SLC when the associated user defined
event (see parameter 13-51 SL Controller Event [x]) is
evaluated as TRUE by the SLC. Events and actions are each
numbered and linked in pairs. This means that when the
first event is fulfilled (attains the value TRUE), the first
action is executed. After this, the conditions of the second
event is evaluated and if evaluated TRUE, the second action
is executed and so on. Only one 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 is evaluated. This means that when the SLC starts, it
evaluates the first event (and only the first event) each scan
interval. Only when the first event is evaluated TRUE, the
SLC executes the first action and start evaluating the
second event. 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 the first event/the first
action. Illustration 3.36 shows an example with 3 event/
actions.

Starting and stopping the SLC
Starting and stopping the SLC can be done by selecting [1]
On or [0] Off in parameter 13-00 SL Controller Mode. The
SLC always starts in state 0 (where it evaluates the first
event). 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. 13-03 Reset SLC resets
all SLC parameters and starts programming from scratch.
3.12.1 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.
