3.10.1 13-** Prog. Features
Smart Logic Control (SLC) is essentially a sequence of user
defined actions (see 13-52 SL Controller Action [x]) executed
3 3
by the SLC when the associated user defined event (see
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 fulfilled
(attains the value TRUE), [0] action is executed. After this,
the conditions of [1] event will be evaluated and if
evaluated TRUE, [1] action will be executed and so on. Only
one event will be 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 will be
evaluated. This means that when the SLC starts, it
evaluates [0] event (and only [0] event) each scan interval.
Only when [0] event is evaluated TRUE, will the SLC
execute [0] action and start evaluating [1] 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 [0] event/[0] action. The
illustration shows an example with three event/actions

Starting and stopping the SLC:
Starting and stopping the SLC can be done by selecting [1]
On or [0] Off in 13-00 SL Controller Mode. The SLC always
starts in state 0 (where it evaluates [0] event). The SLC
starts when the Start Event (defined in 13-01 Start Event) is
evaluated as TRUE (provided that [1] On is selected in
13-00 SL Controller Mode). The SLC stops when the Stop
Event (13-02 Stop Event) is TRUE. 13-03 Reset SLC resets all
SLC parameters and starts programming from scratch.
3.10.2 13-0* SLC Settings
Use the SLC settings to activate, deactivate and reset the
Smart Logic Control sequence. The logic functions and
comtors are always running in the background, which
opens for sete control of digital inputs and outputs.
