Members

Member	Value	Description
None	0	The fields are represented as Variant. The value of this enum member is 0.
RawData	32	If this flag is set, the values of the dataset are encoded as structure and all other field related flags are ignored. The value of this enum member is 32.
ServerPicoseconds	16	The DataValue structure field ServerPicoSeconds is included in the DataSetMessages. Remarks: If this flag is set, the fields are represented as DataValue. This flag is ignored if the ServerTimestamp flag is not set. Note that the casing (Picoseconds vs. PicoSeconds) is different from the value name in the OPC UA specification. The value of this enum member is 16.
ServerTimestamp	4	The DataValue structure field ServerTimestamp is included in the DataSetMessages. Remarks: If this flag is set, the fields are represented as DataValue. The value of this enum member is 4.

This flag is ignored if the SourceTimestamp flag is not set. Note that the casing (Picoseconds vs. PicoSeconds) is different from the value name in the OPC UA specification. The value of this enum member is 8.
SourceTimestamp	2	The DataValue structure field SourceTimestamp is included in the DataSetMessages. Remarks: If this flag is set, the fields are represented as DataValue. The value of this enum member is 2.
