WriteDB_Confirm (Tag 42h)
Description: The WriteDB_Confirm has to be sent by the FPMA when new data have been correctly recorded. The
DB_Data_Id_Echo contains the identifier of the data and the value read at its memory location. It may have the same structure
as DB_Data_Id or be different (see Section “The Objects Available” for more details on each object).

WriteDB_Error (Tag 43h)
