11.1 IsPresent

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.

11.2 ActivateAdditive

Set value to activate the additive.

11.3 AdditiveActivated

Is true if the additive is activated.

11.4 Status

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

Detailed information may be published via AdditiveAlarmType.

Table 24 – AdditiveStatusEnumeration
Name Value Description
GOOD0Additive has no error or warning
WARNING1The additive has an undefined warning, but no need to stop the production. Detailed information may be published via an alarm (HelpOffNormalAlarmType).
ADVANCE_WARNING_ADDITIVE_CHANGE2Warning, additive change is imminent. No need to stop the process.
ERROR_EMPTY3Error, the additive is empty. Production needs to be stopped.
ERROR4The additive has an error and process needs to be stopped. Detailed information may be published via an alarm (HelpOffNormalAlarmType).

11.5 AdditiveFraction

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

11.6 AdditiveStrokeVolume

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

11.7 ActivateClosedLoopControl

Activate the closed loop control of the additive.

11.8 ClosedLoopControlActivated

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.
