3.13.1 13-** Prog. Features
Smart logic control (SLC) is a sequence of user-dened
actions (see parameter 13-52 SL Controller Action [x])
executed by the SLC when the associated user-dened
event (see parameter 13-51 SL Controller Event [x]) is
evaluated as true by the SLC. Events and actions are each
numbered and linked together in pairs. This means that
when [0] event is fullled (attains the value true), [0] action
is executed. After this, the conditions of [1] event are
evaluated and if evaluated true, [1] 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 [0] event
(and only [0] event) at each scan interval. Only when [0]
event is evaluated true, the SLC executes [0] action and
starts evaluating [1] 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 [0] event/[0] action.
Illustration 3.35 shows an example with 3 events/actions.

Illustration 3.35 Example with 3 Events/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 [0] event). 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.
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] O Disables the smart logic controller.
[1] On Enables the smart logic controller.
13-01 Start Event
Option: Function:
Select the boolean (true or false)
input to activate smart logic
control.
[0] False Enters the xed value of false in the
logic rule.
[1] True Enters the xed value of true in the
logic rule.
