Modbus communication: Network smart panel, read or write the register through rs485, realizing distant monitor and output control. MODBUS RTU protocol is adopted. Serial port parameter settings: Baud rate:”9600”, check bit:”null”, data bit: “8”, stop bit: “1”.Two instructions distance: 100ms
(1) Communication format
|Function code||Data address||Communication data||CRC Check|
(2) Communication device No.
1----255, factory default address; OXFF is broadcast address
Under broadcast mode, write is permitted, not read. No data back from slave device.
(3) CRC16-1 check calculation methodology
CRC set 16-bit of register to 0xffff, ,and put the near two 8-bit data in to the register, every 8-bit data produce CRC,not including start bit, stop bit and parity check bit. When producing CRC, every 8-bit data operate xor with data in register with result of move 1-bit to the right and fill MSB with “0”,check “LSB”.If LSB is “1”,xor with default data. If LSB is “0”,no xor. Repeating above process until move 8 times, next 8-bit data operate xor with the current value. After end of data operation,the final value is CRC value.
