Communication Protocol

    The product uses RS485 MODBUS-RTU standard protocol format, all operation or reply commands are hexadecimal data. The default device address is 1 when the device leaves the factory, and the module or NON-Recorder default baud rate is 9600,8,n,1 ,but data recorder default baud rate is 115200 .
1. Read data (function code 0x03)
    Inquiry frame (hexadecimal), sending example: query 1 data of 1# device, the upper computer sends the command: 01 03 00 00 00 01 84 0A .
Address Function Code Start Address Data Length Check Code
010300 0000 0184 0A
    For the correct query frame, the device will respond with data: 01 03 02 00 79 79 A6 , response format:
Address Function Code LengthData 1Check Code
0103 0200 79 79 A6
    Data description: The data in the command is hexadecimal, take data 1 as an example, 00 79 is converted to decimal value as 121, assuming the data magnification is 100, then the real value is 121/100=1.21, Others and so on.

  For example, the range is 0~30m/s, the analog output is 4~20mA current signal, wind speed and current The calculation relationship is as shown in the formula: C = (A2-A1) * (X-B1) / (B2-B1) + A1, where A2 is wind speed range upper limit, A1 is the lower limit of the range, B2 is current output range upper limit, B1 is the lower limit, X is the currently read wind speed value, and C is the calculated current value. The list of commonly used values is as follows:

1928.1(30-0)*(19-4)÷(20-4)+0
2030.0(30-0)*(20-4)÷(20-4)+0
    As shown in the above formula, when measuring 8mA, current current is 11.5m/s。
  For example, the range is 0~30m/s, the analog output is 0~5V DC0-5Vvoltage signal, wind speed and DC0-5Vvoltage The calculation relationship is as shown in the formula: C = (A2-A1) * (X-B1) / (B2-B1) + A1, where A2 is wind speed range upper limit, A1 is the lower limit of the range, B2 is DC0-5Vvoltage output range upper limit, B1 is the lower limit, X is the currently read wind speed value, and C is the calculated DC0-5Vvoltage value. The list of commonly used values is as follows:
DC0-5Vvoltage(V)wind speedValue (m/s) Calculation Process
00.0(30-0)*(0-0)÷(5-0)+0
16.0(30-0)*(1-0)÷(5-0)+0

424.0(30-0)*(4-0)÷(5-0)+0
530.0(30-0)*(5-0)÷(5-0)+0
    As shown in the above formula, when measuring 2.5V, current DC0-5Vvoltage is 15m/s。
