MODBUS address1

Read temperature input (0x03))

Host Send: addr 03 regH regL numH numL crcH crcL

Return from the machine: addr 03 len d0H d0L & hellip; & hellip; dnH dnL crcH crcL

Explanation: Register addresses start counting from 0, and numH numL represents the number of routes to read the temperature. Benka has eight routestemperatureInput, using 12 bitADC, each waytemperatureinputData takes up two bytes. For example, to read routes 2 and 3, the number of registers with an address of 0001 is 0002. For example, to read all analog quantities from Route 1 to Route 8, the number of registers with an address of 0000 is 0008. The return data 0-0xFFF represents the analog data collected. For example, the read data is 18C, the decimal number is 396, and the temperature is 39.6 degrees.

Example: Reading from Route 1 to Route 8temperature

Host Send: 01 03 00 00 00 08 440C

Return from aircraft: 01 03 0C d0H d0L & hellip; & hellip; d5H d5L crcH crcL

MSG [0] = ip_Addr; //slave address
MSG [1] = 0x04; // Read a single register
MSG [2]= (byte) (data_Addr & gt; & gt; 8); // register address high bit
MSG [3]= (byte) data_Addr; //low register address
MSG [4] = 0x00; // High bit of data length to read
MSG [5] = 0x01; // The base of the length of the data to be read
CRC = CRC16 (msg, 6); // Compute CRC
MSG [6]= (byte) (crc & gt; & gt; 8); / / check 8 bits high
MSG [7]= (byte) crc; //Check low 8 bits

Comm.Write(msg);//Send Read Request Zheng

Receive_A_Frame(); //Receive the Zhen response signal

// Add here: Judge the received data
