3.12 Parameters 13-** Smart Logic
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
1
st
event is fulfilled (attains the value TRUE), the 1
st
action
is executed. After this, the 2
nd
event is evaluated and if
evaluated true, the 2
nd
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 the 1
st
event (and
only the 1
st
event) in each scan interval. Only when the 1
st
event is evaluated true, the SLC executes the 1
st
action and
starts evaluating the 2 nd event. It is possible to program
from 1–20 events and actions.
When the last event/action has been executed, the
sequence starts over again from the 1
st
event/the 1
st
action. Illustration 3.40 shows an example with 3 events/
actions.

Illustration 3.40 Smart Logic 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 (if [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.
3.12.1 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.
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 of true in the
logic rule.
