6.8.1 AASSubmodelElementType common attributes

Figure 15 shows an overview about the AASSubmodelElement ObjectType.

Figure 15 – AASSubmodelElementType graphical overview

A data element is a submodel element that is not further composed of other submodel elements (Table 27). A data element is a submodel element that has a value. The type of value may differ for different data elements.

The default value of the variable “ModelingKind” is “Instance”.

For each AASSubmodelElementType instance the semanticId is mapped to the OPC UA HasDictionaryEntry. This is at instance level because the DictionaryEntry refers to the concept dictionary element, which describes the individual instance and not the submodel element type.

The components of the AASSubmodelElementType have additional references which are defined in Table 28.
