The request data for the message is stored at Data Table Address N7:1.
The Size in Bytes of the request data is 2 bytes because the data size for
PowerFlex 70 drive parameter 101 - [Preset Speed 1] is 2 bytes (1 word).
No Data Table Address is specified for the response data since the Write
Parameter service has no response data.
