PubSubConfigurationDataType – OPC Unified Architecture

6.2.12.1 PubSubConfigurationDataType

This Structure DataType is used to represent the PubSub configuration of an OPC UA Application. The PubSubConfigurationDataType is formally defined in Table 86.

Table 86 – PubSubConfigurationDataType structure

Name	Type	Description
PubSubConfigurationDataType	Structure
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.
Enabled	Boolean	The enabled state of the PubSub configuration. This Enable state corresponds to the PubSub Status of the PublishSubscribe Object.

Its representation in the AddressSpace is defined in Table 87.

PubSub Parameters Configuration

If the PubSub configuration is stored in a file, the UABinaryFileDataType and the related definitions in OPC 10000-5 shall be used to encode the file content. The structure of the UABinaryFileDataType file with typical values for a PubSub configuration is described in Table 88.

Table 88 – PubSubConfiguration file content

Field	Type	Typical Values
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.
schemaLocation	String	Null or empty
fileHeader	KeyValuePair[]	Null or empty
Body	BaseDataType	PubSubConfigurationDataType Structure The PubSub configuration represented by the PubSubConfigurationDataType.
