Parameter Description

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.

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

the start event (defined in parameter LC-01 Start Event) is

evaluated as TRUE (provided that [1] On is selected in

parameter LC-00 Logic Controller Mode). The LC stops when

the stop event (parameter LC-02 Stop Event) is TRUE.

Parameter LC-03 Reset Logic Controller resets all LC

parameters and starts programming from scratch.
