This standard Object is the browse entry point for VariableType Nodes. Figure 5 illustrates the structure beneath this Node. Only Organizes References are used to relate Objects and VariableTypes to the “VariableTypes” standard Object. The “VariableTypes” Object shall not reference any other NodeClasses.
Figure 5 – VariableTypes Organization
The intent of the “VariableTypes” Object is that all VariableTypes of the Server are either directly or indirectly accessible browsing HierarchicalReferences starting from this Node. However, this is not required and Servers might not provide some of their VariableTypes, because they may be well-known in the industry, such as the “BaseVariableType” defined in 7.2.
The “VariableTypes” Object is formally defined in Table 84.
