The AddNodes Service allows specifying the Attributes for the Nodes to add. The NodeAttributes is an extensible parameter whose structure depends on the type of the NodeClass being added. It identifies the NodeClass that defines the structure of the Attributes that follow. The parameterTypeIds are defined in Table 153. The ExtensibleParameter type is defined in 7.17.

Description |
|
ObjectAttributes |
Defines the Attributes for the Object NodeClass. |
|
VariableAttributes |
Defines the Attributes for the Variable NodeClass. |
|
MethodAttributes |
Defines the Attributes for the Method NodeClass. |
|
ObjectTypeAttributes |
Defines the Attributes for the ObjectType NodeClass. |
|

|
ReferenceTypeAttributes |
Defines the Attributes for the ReferenceType NodeClass. |
|
DataTypeAttributes |
Defines the Attributes for the DataType NodeClass. |
|
ViewAttributes |
Defines the Attributes for the View NodeClass. |
|
GenericAttributes |
Defines an id and value list for passing in any number of Attribute values. It should be used instead of the NodeClass specific structures since it allows the handling of additional Attributes defined in future specification versions. |
Table 154 defines the bit mask used in the NodeAttributes parameters to specify which Attributes are set by the Client.
