The following Figure 22 shows the deprecated mapping of the above example. This mapping is deprecated since it is deprecated in OPC UA V1.04.
Ctrl servers must support the binary encoding (“Default Binary”). Additionally, other encodings may be provided (not shown in above figure). A Server may provide, for backward compatibility, the deprecated DataTypeDictionary Variable describing all necessary DataTypes. Each DataType is represented by a DataTypeDescription Variable. Optionally, a Property DictionaryFragment may be available, allowing clients not to read the complete DataTypeDictionary in order to get the information about only a single DataType (not shown in above figure).
