The Attributes of Nodes, their DataTypes and descriptions are defined in OPC 10000-3. Attributes not marked as optional are mandatory and shall be provided by a Server. The following tables define if the Attribute value is defined by this document or if it is server-specific.
For all Nodes specified in this document, the Attributes named in Table 7 shall be set as specified in the table.
|DisplayName||The DisplayName is a LocalizedText. Each Server shall provide the DisplayName identical to the BrowseName of the Node for the LocaleId “en”. Whether the server provides translated names for other LocaleIds are server-specific.|
|Description||Optionally a server-specific description is provided.|
|NodeClass||Shall reflect the NodeClass of the Node.|
|NodeId||The NodeId is described by BrowseNames as defined in 220.127.116.11.|
|WriteMask||Optionally the WriteMask Attribute can be provided. If the WriteMask Attribute is provided, it shall set all non-server-specific Attributes to not writable. For example, the Description Attribute may be set to writable since a Server may provide a server-specific description for the Node. The NodeId shall not be writable, because it is defined for each Node in this document.|
|UserWriteMask||Optionally the UserWriteMask Attribute can be provided. The same rules as for the WriteMask Attribute apply.|
|RolePermissions||Optionally server-specific role permissions can be provided.|
|UserRolePermissions||Optionally the role permissions of the current Session can be provided. The value is server-specific and depends on the RolePermissions Attribute (if provided) and the current Session.|
|AccessRestrictions||Optionally server-specific access restrictions can be provided.|
