Modbus register list
System configuration reading parameter register address and data communication (function code 03H read, 10H write)
| Serial No. | Definition | Register address | Read /write | Specific instructions |
|---|---|---|---|---|
| 1 | Address and baud rate | 0004H | Read /write | The default value is 0106H. The default address is 01H, and the default communication format is 8, N, 1,9600bps illustrate: The 8-bit high byte is the address, 1~255. 0 is the broadcast address. The high 2 bits of the low byte are the data format bits. “00” means 10 bits, no check, that is, “8, N, 1”. “01” means 11 bits, even parity, that is, “8, E, 1”. “10” means 11 bits, odd parity, that is, “8, O, 1”. “11” means 11 bits, no parity, 2 stop bits, that is, “8, N, 2”. The lower four bits of the low byte are the baud rate, 5-4800bps, 6-9600bps, 7-19200bps |
| 2 | Signal source switching settings | 0 005H _ | Write | When 0x 0001 is written , the module automatically switches modes, and writing other values is invalid. |
