| DataSetWriterId | 0 | If this flag is set, a DataSetWriterId shall be included in the DataSetMessage header. |
| MetaDataVersion | 1 | If this flag is set, the ConfigurationVersion is included in the DataSetMessage header. |
| SequenceNumber | 2 | If this flag is set, the DataSetMessageSequenceNumber is included in the DataSetMessage header. |
| Timestamp | 3 | If this flag is set, a timestamp shall be included in the DataSetMessage header. |
| Status | 4 | If this flag is set, an overall status is included in the DataSetMessage header. |
| MessageType | 5 | If this flag is set, the message type is included in the DataSetMessage header. |
| DataSetWriterName | 6 | If this flag is set, a DataSetWriterName shall be included in the DataSetMessage header. |
| FieldEncoding1 | 7 | The definition of field encoding configuration through the bits FieldEncoding1 and FieldEncoding2 is defined in Table 112. |
| PublisherId | 8 | The PublisherId is included in the DataSetMessages. This bit shall be false if the NetworkMessageHeader is active. |
| WriterGroupName | 9 | The WriterGroup name is included in the DataSetMessages. If the WriterGroup name is included in the NetworkMessage header, it shall not be included in the DataSetMessages. |
| MinorVersion | 10 | If this flag is set, the MinorVersion field of the ConfigurationVersion is included in the DataSetMessage header. |
| FieldEncoding2 | 11 | The definition of field encoding configuration through the bits FieldEncoding1 and FieldEncoding2 is defined in Table 112. |
The definition of field encoding configuration through the bits FieldEncoding1 and FieldEncoding2 is defined in Table 112.
| FieldEncoding1 | FieldEncoding2 | Description |
| False | True | The JSON VerboseEncoding is used for the DataSetMessage field encoding. |
| True | True | The JSON CompactEncoding is used for the DataSetMessage field encoding. The RawData bit of the DataSetFieldContentMask shall be ignored. |
