DB80: Transparent message format
Byte Initial value (hex) Comment (Hex)
0 00 Req_Control
(00 = Transparent message format.
40 = Transparent message format with SHC sequence)
1 05 Number of preamble bytes (05-14)
2 82 Start character
(02 = Short Frame with command 0)
(82 = Long Frame with other commands)
3 98 Address
(with command 0, the address is exactly 1 byte long and has
the value 0.)
4 CF
5 38
6 84
7 F0
8 01 Command (CMD)
9 00 Length in bytes
10 98 Checksum (CHK)
(calculated as EXOR addition starting from byte 2 "Start
character" up to the last byte of the command. The check‐
sum does not have to be sent with the request.)
A HART command can also be sent in compact message format. In this case, the data transmitted
via DB 80 is reduced to 4 bytes.
