The parameter DataSetOffsetwith the DataType UInt16is the offset in bytes inside a NetworkMessageat which the DataSetMessageis located, relative to the beginning of the NetworkMessage.

The default value 0 indicates that the position of the DataSetMessagein a NetworkMessageis not fixed. If the DataSetWriteris disabled and the DataSetOffsetis not 0, the valid flag of the DataSetFlags1in the DataSetMessageheader at the offset shall be false.

This parameter should be set if the PayloadHeaderflag in the NetworkMessageContentMaskis false and therefore the NetworkMessagehas a fixed layout.
