    Device communication

    Basic communication parameters

    The UART interface or 485 interface uses ModBus-RTU protocol for communication. The default communication communication parameters are:

    Baud rate: 9600 Data bits: 8 bits Parity mode: No parity Stop bit length: 1 bit The device ModBus communication address is 1.

    Data frame format definition

    Adopt Modbus-RTU communication protocol, the format is as follows:

    Initial structure ≥4 bytes of time

    Address code= 1 byte

    Function code= 1 byte

    Data area= N bytes

    Error check = 16-bit CRC code

    End structure≥4 bytes of time

    Address code: default 01.

    Function code: The instruction function of the command sent by the host. This module only uses function code 0x03 (read register data).

    Data area: The data area is the specific communication data. Note that the 16-bit data high byte is in front!

    CRC code: Two-byte check code

    • Host inquiry frame structure:

    Address Code: 1 Byte; Function Code: 1 Byte; Register Start Address: 2 Byte; Register length: 2 Byte; Check Code Low: 1 Byte; Check Code High: 1 Byte

    • Module response frame structure:

    Address Code: 1 Byte Function Code: 1 Byte Numbers of Valid: 1 Byte First Data Area: 2 Byte; Second Data Area: 2 Byte; N Data Area: 2 Byte; Check code: 2 Byte

    • Register Address

    Register address: 0000 H; PLC or Configuration address: 40001 ; Content: Instantaneous noise value Upload data is 10 times true; Operation: Read only

    • Communication protocol examples and explanations

    Example: Read module noise value

    Inquiry frame:

    Address Code: 0x01; Function Code: 0x03; Starting Address: 0x00 0x00; Data Length: 0x00 0x01; Check Code Low: 0x84; Check Code High: 0x0A

    Response frame: (for example, the current noise is 71.3dB)

    Address Code: 0x01; Function Code: 0x03 ; Numbers of Retur-ed Valid Bytes: 0x02 ; Current Noise Value: 0x02 0xC9 ; Check Code Low: 0x79 ; Check Code High: 0x72
