6.10 Parameters: 13-** Smart Logic Control
6.10.1 Prog. Features
Smart Logic Control (SLC) is essentially a sequence of user
defined actions (see
[x]) executed
by the SLC when the associated user defined
event
(see
[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 will lead to an associated
Action as illustrated:

Illustration 6.12
Events and
actions
are each numbered and linked together
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] will be evaluated and if
evaluated TRUE,
action
[1] 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
event
[0] (and only
event
[0]) each scan interval.
Only when
event
[0] is evaluated TRUE, will the SLC
execute
action
[0] and start 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]. The
illustration 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
event
[0]). The SLC starts when the Start Event (defined in
) is evaluated as TRUE (provided that
On
[1] is selected in
13-00 SL Controller Mode
). The SLC stops
when the
Stop Event
) is TRUE.
resets all SLC parameters and start programming from
scratch.
NOTE
SLC is only active in AUTO mode, not Hand On mode
6.10.2 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.
13-00 SLC Controller Mode
Option:
Function:
[ 0]
*
Off Disables the Smart Logic Control.
[1]
On Enables the Smart Logic Control to start when a start
command is present, e.g. via a digital input.
13-01 Start Event
Option:
Function:
[0]
*
