Name	Type	Description
PubSubCommunicationLinkConfigurationDataType	Structure	Subtype of CommunicationLinkConfigurationDataType
DataSetReaderRef	0:PubSubConfigurationRefDataType	If not null, specifies the DataSetReader as supplied with the PubSubCommunicationConfigurationDataType. The ConfigurationMask shall contain a ReferenceReader bit only.
ExpectedSubscribedDataSetVersion	0:ConfigurationVersionDataType	Specifies the expected ConfigurationVersion of the SubscribedDataSet’s DataSetMetaData. For a heartbeat, the MajorVersion and the MinorVersion shall be set to 0.
DataSetWriterRef	0:PubSubConfigurationRefDataType	If not null, specifies the DataSetWriter as supplied with the PubSubCommunicationConfigurationDataType. The ConfigurationMask shall contain a ReferenceWriter bit only.
ExpectedPublishedDataSetVersion	0:ConfigurationVersionDataType	Specifies the expected ConfigurationVersion of the PublishedDataSet’s DataSetMetaData. For a heartbeat, the MajorVersion and the MinorVersion shall be set to 0.

The PubSubCommunicationLinkConfigurationDataType representation in the AddressSpace is formally defined in Table 149.
