PublishedDataSets |
PublishedDataSetDataType[] |
The PublishedDataSets contained in the configuration. The PublishedDataSetDataType is defined in 6.2.3.5. |
|
Connections |
PubSubConnectionDataType[] |
The PubSubConnections contained in the configuration. The PubSubConnectionDataType is defined in 6.2.7. The connection includes WriterGroups and ReaderGroups. |

Namespaces |
String[] |
Namespace URIs for namespace indices used in the body. Examples are NodeIds contained in PublishedDataSets. The OPC UA namespace is skipped. The DataTypes used for configuration are defined in the OPC UA namespace. |

structureDataTypes |
StructureDescription[] |
Null or empty DataTypes used for configuration are defined by OPC UA. The DataTypes used in DataSetMetaData are described in the DataTypeSchemaHeader of the associated DataSetMetaData. This field is only used if KeyValuePairs for configuration properties contain Structure DataTypes not defined by OPC UA. |
|
enumDataTypes |
EnumDescription[] |
Null or empty DataTypes used for configuration are defined by OPC UA. The DataTypes used in DataSetMetaData are described in the DataTypeSchemaHeader of the associated DataSetMetaData. This field is only used if KeyValuePairs for configuration properties contain Structure DataTypes not defined by OPC UA. |
|
simpleDataTypes |
SimpleTypeDescription[] |
Null or empty DataTypes used for configuration are defined by OPC UA. The DataTypes used in DataSetMetaData are described in the DataTypeSchemaHeader of the associated DataSetMetaData. This field is only used if KeyValuePairs for configuration properties contain Structure DataTypes not defined by OPC UA. |
