getset |
Id of the Attribute. This shall be a valid Attribute id. The IntegerIds for the Attributes are defined in NodeAttributesMask.
This parameter specifies the BrowseName of the DataTypeEncoding that the Server should use when returning the Value Attribute of a Variable. It is an error to specify this parameter for other Attributes. A Client can discover what DataTypeEncodings are available by following the HasEncoding Reference from the DataType Node for a Variable. OPC UA defines BrowseNames which Servers shall recognize even if the DataType Nodes are not visible in the Server address space. These BrowseNames are:
| DefaultBinary | The default or native binary (or non-XML) encoding. |
| DefaultXML | The default XML encoding. |
Each DataType shall support at least one of these encodings. DataTypes that do not have a true binary encoding (e.g. they only have a non-XML text encoding) should use the DefaultBinary name to identify the encoding that is considered to be the default non-XML encoding. DataTypes that support at least one XML-based encoding shall identify one of the encodings as the DefaultXML encoding. Other standards bodies may define other well-known data encodings that could be supported. If this parameter is not specified then the Server shall choose either the DefaultBinary or DefaultXML encoding according to what Message encoding (see Part 6) is used for the Session. If the Server does not support the encoding that matches the Message encoding then the Server shall choose the default encoding that it does support. If this parameter is specified for a MonitoredItem, the Server shall set the StructureChanged bit in the StatusCode (see 7.33) if the DataTypeEncoding changes. The DataTypeEncoding changes if the DataTypeVersion of the DataTypeDescription or the DataTypeDictionary associated with the DataTypeEncoding changes.

This parameter is used to identify a single element of an array, or a single range of indexes for arrays. If a range of elements is specified, the values are returned as a composite. The first element is identified by index 0 (zero). This parameter is null if the specified Attribute is not an array. However, if the specified Attribute is an array, and this parameter is null, then all elements are to be included in the range.
