Figure 44 depicts the ObjectType for the PubSub DataSetWriter model and its components and the relations to other parts of the model.
Figure 44 – DataSet Writer model overview
An instance of this ObjectType represents the configuration for a DataSetWriter. The DataSetWriterType is formally defined Table 248.
A DataSetWriter that creates DataSetMessages based on a PublishedDataSet shall reference the related PublishedDataSet with an inverse DataSetToWriter Reference.
A DataSetWriter that creates heartbeat DataSetMessages shall not have a reference to a PublishedDataSet.

The DataSetWriterId is defined in 6.2.4.1.
The DataSetFieldContentMask is defined in 6.2.4.2.
The KeyFrameCount is defined in 6.2.4.3. The Property shall be present for PublishedDataSets that provide cyclic updates of the DataSet.
The DataSetWriterProperties is defined in 6.2.4.4.
The transport protocol mapping specific setting settings are provided in the optional Object TransportSettings. The DataSetWriterTransportType is defined in 9.1.7.3. The Object shall be present if the transport protocol mapping defines specific parameters.
The message mapping specific setting settings are provided in the optional Object MessageSettings. The DataSetWriterMessageType is defined in 9.1.7.4. The Object shall be present if the message mapping defines specific parameters.
The Status Object provides the current operational status of the DataSetWriter. The PubSubStatusType is defined in 9.1.10. The state machine for the status and the relation to other PubSub Objects like PubSubConnection and PubSubGroup is defined in 6.2.1.
The Diagnostics Object provides the current diagnostic information for a DataSetWriterType Object. The PubSubDiagnosticsDataSetWriterType is defined in 9.1.11.11.
This ObjectType is the abstract base type for Objects defining protocol-specific transport settings of DataSetMessages. The DataSetWriterTransportType is formally defined Table 249.
