This Property informs the client if the additive is physically present. May be FALSE e.g. if the server does not create dynamically instances and has a fixed number of instances for the additives out of which some are currently not used.

Set value to activate the additive.

Is true if the additive is activated.

Actual status of the additive provides a minimal error handling for devices without event support.

Detailed information may be published via AdditiveAlarmType.

Description

GOOD

0

Additive has no error or warning

WARNING

1

The additive has an undefined warning, but no need to stop the production. Detailed information may be published via an alarm (HelpOffNormalAlarmType).

ADVANCE_WARNING_ADDITIVE_CHANGE

2

Warning, additive change is imminent. No need to stop the process.

ERROR_EMPTY

3

Error, the additive is empty. Production need to be stopped.

ERROR

4

The additive has an error and process needs to be stopped. Detailed information may be published via an alarm (HelpOffNormalAlarmType).

Contains the SetValue, ActualValue, LowerTolerance and UpperTolerance of the additive fraction in percent.

Defines the value of additive per shot/stroke. Total amount stays the same (defined by AdditiveFraction). Used to distribute the total amount to several strokes.

Unit: mm³ or in³

Activate the closed loop control of the additive.

Is false if the closed loop control of the additive is not activated. In this case the ActualValues of AdditiveFraction and AdditiveVolume are equal to the SetValues.

Is true if the closed loop control of the additive is activated. In this case, the ActualValues of AdditiveFraction and AdditiveVolume are the measured values.
