Operating guide SonoMeter 40 - Wired M-Bus protocol description
1. General structure of
protocol
1.1. General features of
protocol
Meter uses a M-bus protocol .
Default baud rate: 2400 bps, Even, 1 Stop.
Baud rate can be changed.
Protocol is the same for Mbus interface and for optical interface.
Primary address of Mbus is individual for Mbus interface and for optical interface.
1.2. Data strings Data string to meter SND_NKE:
1 2 3 4 5
10h 40h A CS 16h
A - M-bus primary address of meter
CS – control sum (the youngest byte of amount of 2-nd and 3-rd bytes)
Data string to meter SND_UD2
1 2 3 4 5 6 7 8...n-2 n-1 n
68h 68hL L 53h
73h A 51h Data
bytes CS 16h
L - length of string (the number of bytes from 5-th to n-2 byte)
A - M-bus primary address of meter
CS – control sum (the youngest byte of amount of 5-th to n-2 bytes)
Data string to meter REQ_UD2:
1 2 3 4 5
10h 5Bh
7Bh A CS 16h
A - M-bus primary address of meter
CS - control sum (the youngest byte of amount of 2-nd and 3-rd bytes)
Answer of the meter CON:
E5h
Answer of the meter RSP_UD2:
1 2 3 4 5 6 7 8...11 12, 13 14 15 16 17 18,19
68h 68hL L C A CI ID Man Vrs Md TC St Sign
20 ... ... ... ... ... ... n-2 n-1 n
DIF VIF Data DIF VIF Data CS 16h
L - length of string (the number of bytes from 5-th to n-2 byte)
C – „C field“ (08)
A - M-bus primary address of meter
CI - „CI field“
ID – identification number of meter (BSD8, used for secondary addressing, can be changed - see
paragraph 4.1),
Man – Manufacturer code (Danfoss A/S manufacturer code is „DFS“, 10 D3)
Vrs – number of protocol version (0Bh)
Md – code of medium (for „heat / cold energy“: 0Dh)
TC – counter of telegrams
St - meter status code
Sign - 00 00
The bytes 20...n-2 is data from meter:
DIF – code of data format
VIF – code of data units
Data– values of data
CS – control sum (the youngest byte of amount of 5-th to n-2 bytes).
