To meet the range of aspects of the assets which have to be described in the AAS a set of submodel element types are defined. Each submodel element type represents one of these aspects. Figure 14 provides a general overview.
Figure 14 – SubmodelElement Subtypes
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.

Figure 20 shows an overview about the AASOperation ObjectType.
Figure 20 – AASOperationType graphical overview
AASOperationType is defined in Table 38. It encapsulates the standard OPC UA Method “Operation”. All rules for the OPC UA Method NodeClass declaration apply. “Operation” is defined without Arguments but with the OptionalPlaceholder ModellingRule. As defined in OPC 10000-3, this rule allows the inclusion of Arguments to this Method on sub-types or on instances.
