This ObjectType represents a Subscriber defined standalone DataSet. A standalone subscribed DataSet can exist without DataSetReader and is used to define a DataSet from the Subscriber side. A DataSetReader can be configured and connected to the standalone DataSet if a Publisher provides the DataSetMessages defined by the DataSetMetaData in the standalone DataSet. The StandaloneSubscribedDataSetType is formally defined in Table 279.

PubSub Model SubscribedDataSet Standalone

The SubscribedDataSetType defined in 9.1.9.1 describes the processing of the received DataSet in a Subscriber.

The DataSetMetaData is defined in 6.2.9.4. A Publisher must be configured to send DataSetMessages that comply with the DataSetMetaData in the standalone subscribed DataSet.

The IsConnected Property with DataType Boolean indicates if the standalone subscribed DataSet is connected to a DataSetReader. A standalone subscribed DataSet can only be connected to one DataSetReader. If a DataSetReader is connected, the DataSetReader Object shall share the Nodes SubscribedDataSet and DataSetMetaData with the StandaloneSubscribedDataSet Object. The relation between standalone SubscribedDataSet and the connected DataSetReader is provided in both directions through the inverse References from the SubscribedDataSet Object.
