The RS485 port of the Fusheng SC series controller complies with the ModBus RTU protocol, and its communication format is fixed as "9600 E 8 1". Its meaning is:
- Baud rate: 9600 bps
- Inspection position: Occasional verification
- Data bits: 8 Position
- Stop position: 1 Position
Note:: The baud rate of some controllers in Fusheng is adjustable. To avoid errors, Strongly recommend using silent Recognize the set value: 9600bps
Fusheng SC The series controller only supports ModBUS RTU of Number and 3 Number function code 6 Its communication format, As follows: Number function code:
- 3 Read: Bytes N Host request
Slave address:
| Function code | Initial address | Data length | Inspection code | CRC Slave response |
Slave address:
| Function code | Data length | Data content | Verification code | CRC Number function code |
- 6 Write: Bytes 1 Host request
Slave address:
| Function code | Register address | Set numerical values | Verification code | CRC Slave response |
Slave address:
| Function code | Register address | Set numerical values | Verification code | CRC Series controller communication address table |

Note:: 1. “Remote startup”And“Remote shutdown”, “Forced loading”And“Forced uninstallation”They are interlocked, One finger Order placement“1”Time, The other one must be reset to zero.
2. To make“Remote startup”Or“Remote shutdown”The instruction is valid, First place“1”, 2~3 Clear to zero in seconds.
