3.25 LC-## Logic Controller
3.25.1 LC-## Logic Controller
Logic Controller (LC) is a sequence of user-defined actions
(see
parameter LC-52 Logic Controller Action
[x]) executed by
the LC when the associated user-defined event (see
parameter LC-51 Logic Controller Event
[x]) is evaluated as
TRUE by the LC. 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 are
evaluated and if evaluated TRUE, [1] 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 LC) during the
current scan interval and no other events are evaluated.
This means that when the LC starts, it evaluates [0] event
(and only [0] event) at each scan interval. Only when [0]
event is evaluated TRUE, the LC executes [0] action and
starts evaluating [1] event. It is possible to program 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.
shows an example with 3 events/actions

Starting and stopping the LC
Start and stop the LC by selecting
[1] On
or
[0] Off
in
parameter LC-00 Logic Controller Mode
. The LC always starts
in state 0 (where it evaluates
[0] event
). The LC starts when
) is
evaluated as TRUE (provided that
[1] On
is selected in
parameter LC-00 Logic Controller Mode
). The LC stops when
the stop event (
) is TRUE.
Parameter LC-03 Reset Logic Controller
resets all LC
parameters and starts programming from scratch.
