In OP in RTU format, 03H: register reading and 10H: register writing are existed. The followings are descriptions for registers
used in batch operation.
1） Register reading
· OP=03H
· During register reading, the data listed in the following table can be read.
Refer to the [(6) Register address] described later for the register address of all data.
Up to 5 data can be read simultaneously.
For setting errors of function codes, please refer to list of error codes.
2） Register writing
· OP = 06H (single register writing)／OP = 10H (continuous register writing)
· With register writing, the data can be written and changed.
Refer to the [(6) Register address] described later for the register address of all data.
Even with the continuous register writing, only one data can be writen into the function code data at each time.
⑴→'02'（2）→'F3'
2) Number of register (2 byte fixed)
Example: number of registers: 2
(3)→'00'(4)→'02'
3) Number of data (1 byte fixed)
Example: 4 data are read
(5) →'04'
4) Data content (variable, byte = number of data (1))
Example: 4 data are read
(6)→'00' (7)→'00' (8)→'13' (9)→'88'
(1)
Example ②: Data content written into one register (06H)
1) Setting of register (2 byte fixed)
Example: register set as 03E8H
(1)→'03' (2)→'E8'
2) Setting of data content (2byte fixed)
Example: data value set as 0001H
(3)→'00' (4)→'01'
・Data (DT) (4byte)
(1)
Example ③ Data content written into the register (10H)
1）Register number (2 byte fixed)
Example: register number 03E8H
⑴→'03'⑵→'E8'
2）Setting of number of registers (2 byte fixed)
Example: writing in two registers
⑶→'00'⑷→'02'
·Data (DT)（4byte）
(1)
Checksum CRC check (2-byte fixed)
Name
0: Broadcast mode
1-254: inverter number of receiver
Data format is fixed as 1byte
Inverter number is the data set by function code F4006
Example: inverter number 2 ②→'02'。
Computer-sent command code +80H;
Top digit 1 means abnormality.
Data Abnormality response data format is fixed as 1-byte
For alarm contents, see list of alarms for dedicated protocol.
