Standard for ModBus RTU telecommunication protocol :
Serial format: data bit 8 bits, stop bit 1 bit, parity bit None, default baud rate 9600bps, serial debugging software set to hex send and receive, two telecommunication intervals of at least 500ms or more, CRC in the manual for the parity bit, 2 bytes. The default device address is 1.
for Modbus CRC checksum steps :
1. Preset the 16 bit register as hexadecimal FFFF, call this register as CRC register;
2. Isolate the first 8 bit data with the lower bit of the CRC register, and put the result in the CRC register;
3. check the lowest bit by shifting the contents of the register one bit to the right (towards the lower bit) and filling the highest bit with a 0;
4. if the lowest bit is 0: repeat step 3 (shift again) if the lowest bit is 1: the CRC register is iso orthogonal to the polynomial A001 (1010 0000 0000 0001);
5. Repeat steps 3 and 4 until it is shifted right 8 times so that the entire 8-bit data is all processed;
6. repeat steps 2 through 5 for the next 8 bit data;
The final CRC register obtained is the CRC code (The CRC code obtained is low front high back).
Troubleshooting :
1. The wind blades does not rotate properly and has a lar
