Change Parameter Response
Note 1
The request header is preceded by the DP and MSAC2 headers. Describing
these however is outside the scope of this manual.
Note 2
If all changes were applied successfully, the Change Parameter Response
frame will contain no data (only the Response Header). If the Change Param-
eter Request frame contained errors, the Change Parameter Response frame
contains a single error data block.
