Parameter Descriptions

3.14 Parameters: 13-** Smart Logic Control

3.14.1 Prog. Features
Smart Logic Control (SLC) is essentially a sequence of user-
3 3
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 leads to an associated action
as illustrated:

Illustration 3.47 Smart Logic Control (SLC)
Events and actions are each numbered and linked 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] are evaluated and if evaluated
TRUE, action [1] 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 are 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, the SLC executes action [0] and starts evaluating
event [1]. 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 event [0]/action [0].

Event (13-02 Stop Event) is TRUE. 13-03 Reset SLC resets all
SLC parameters and start programming from scratch.
NOTICE
SLC is only active in AUTO mode, not Hand On mode
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.
