24 MouldProcessValueType

24.1 MouldProcessValueType definition

The MouldProcessValueType is the ObjectType used for the process values of the mould in the MouldProcessValuesType. It is formally defined in Table 35. It is a Subtype of the ProcessValueType, which is defined in OPC 40001-2 and adds information about the position of the measurement point.

The MouldProcessValueType represents a process-related value in the context of a mould. The value may originate directly from a sensor measurement or may be derived, aggregated, filtered, averaged, or otherwise calculated from one or more measurements.

For further information regarding the name and description of the measuring point, the Node Attributes DisplayName and Description and the mandatory Property SignalTag in the ProcessValueType shall be used.

24.2 Position

The optional Variable Position provides the position of the measured value in cartesian coordinates.

The coordinate system shall be right-handed.

The origin of the coordinate system should be centered in the first parting plane of the mould. The Z-axis should point in the direction of the injection of the first component, while the X-axis shall point towards the control panel of the machine. Figure 6 shows an example of the orientation of the coordinate system.

The 3DCartesianCoordinatesType is defined in OPC 10000-5. For the InstanceDeclaration the ModelingRules of the Property LengthUnit are overridden to mandatory.

24.3 IsContinuousValue

Indicates whether the Process Value is continuously updated.

If TRUE, the value represents a continuously updated process value.

FALSE indicates a value that is updated only at discrete intervals or in response to specific events, typically once per production cycle.
