Register
For double registers (4 – 5, 16 – 17, 28 – 29, 30 – 31) the high register is sent first (big-Endian).
Partial counter (30 – 31) can be reset by writing 0 in both registers in the same message.
R Read Write Description Unit
1 X Firmware-Version Ex: 11 = FW 1.1
2 X Number of supported registers Will give 40
3 X Number of supported flags Will give 0
4–5 X Baudrate Ex: Baudrate High = 1 Baudrate Low = 49664
1 × 65536 + 49664 = 115 200 bps
6 X Not Used Will give 0
7 X Type / ASN function Will give «7E»
8 X Type / ASN function Will give «23»
9 X Type / ASN function Will give «82»
10 X Type / ASN function Will give «30»
11 X Type / ASN function Will give «02»
12 X Type / ASN function Will give «x4»
x : 0 = Non MID
x : 1 = MID
13 X Type / ASN function Will give «0»
14 X Type / ASN function Will give «0»
15 X HW vers. Modif. Ex: 11 = HW 1.1
16–17 X Serial number Unique 32 bit serial number Low
18 X Serial number Unique 32 bit serial number High
19 X Not Used Will give 0
20 X Not Used Will give 0
21 X Not Used Will give 0
22 X Status 0 = no Problem
1 = problem with last communication request
23 X Response Timeout ms
24 X X
1)
Modbus Address Range 1–247
25 X Error register 0 : No error 1 : Error
26 X Not Used Will give 0
27 X Not Used Will give 0
28–29 X WT1 ---->
Counter Energy Consumption
10
–2
kWh (multiplier 0,01)
Ex: WT1 ----> High = 13 WT1 ----> Low = 60383
13 × 65536 + 60383 = 912351 = 9123.51
kWh
30–31 X X WT1 <-----
Counter Energy Feeding Back
10
–2
kWh (multiplier 0,01)
Ex: WT1 <----- High = 13 WT1 <----- Low = 60383
13 × 65536 + 60383 = 912351 = 9123.51 kWh
32 X Not Used Will give 0
33 X Not Used Will give 0
34 X Not Used Will give 0
35 X Not Used Will give 0
36 X URMS phase 1
Effective Voltage of Phase 1
V
Ex: 230 = 230 V
37 X IRMS phase 1
Effective Current of Phase 1
10
–1
A (multiplier 0,1)
Ex: 314 = 31.4 A
38 X PRMS phase 1
Effective active Power of Phase 1
10

kW (multiplier 0,01)
Ex: 1545 = 15,45 kW
39 X QRMS phase 1
Effective reactive Power of Phase 1
10
–2
kvar (multiplier 0,01)
Ex: 1545 = 15,45 kvar
40 X cos phi phase 1 10
–2
