6.2.8.1 General

The ReaderGroup is used to group a list of DataSetReaders. It is not symmetric to a WriterGroup and it is not related to a particular NetworkMessage. The NetworkMessage related filter settings are on the DataSetReaders.

This Structure DataType is used to represent the configuration parameters for ReaderGroups. The ReaderGroupDataType is formally defined in Table 45.
