MODBUS RTU COMMUNICATION PROTOCOL
Baud rate：9600
Data bits：8
Stop bit：1
Check bit：None
1.1 CRC Instruction:
Among all the following instructions, the two bytes of CRC16 in MODBUS RTU protocol are as follows: the low byte comes before the high byte comes after.
In the following instructions, the sensor address 0xFF is assumed (the sensor default address is FF)
1.2 Return error code rule：
When receive error instruction (including CRC16 validation error), the sensor will not return error code. After the instruction is issued 100ms, it fails to receive issuing instruction The upper computer may consider failure and may resend the instruction.
Note: The quantity or length of register in Modbus is two bytes and 16 bits(the high byte comes first and the low byte comes last), Non - byte 8 bits are a unit.
The user shall ensure that the range of the address and the range of quantity of registers are within the system range.If it exceeded, the output of the sensor will be unpredictable. The user shall ensure that the MODBUS meets the requirements of this manual in the software design of the upper computer
