Parameter Description

3.12 Parameters 13-** Smart Logic Control

3.12.1 13-** Prog. Features
Smart Logic Control (SLC) is essentially a sequence of user
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. Events and actions are each numbered and linked
together 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 will
be evaluated and if evaluated TRUE, the second 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 the first event (and only the first
event) each scan interval. Only when the first event is
evaluated TRUE, will the SLC execute 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 3.34 shows an example with three event/
actions.

Starting and stopping the SLC
Starting and stopping the SLC can be done by selecting
On [1] or Off [0] in 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 13-01 Start
Event) is evaluated as TRUE (provided that On [1] 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.

3.12.2 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.
13-00 SL Controller Mode
Option: Function:
[0] Off 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 fixed value of FALSE in the
*
logic rule.
[1] True Enters the fixed value TRUE in the logic
rule.
