High Byte Count
The number of bytes represents the total number of bytes written for this operation.If the data is of type
char, the number of bytes is 0x0001; if the data is of type int, the number of bytes is 0x0002; if the data is of
type float, the number of bytes is 0x0004.
6)
Low Byte Count
The number of bytes represents the total number of bytes written for this operation.
7)
Number of Data
The number of data indicates the total number of data written in this operation.
8)
Data Byte 1 --Data Byte N
The data byte is to write the set data content to the instrument.
9)
CRC High and CRC Low
CRC 16-bit check, using the look-up table method for CRC check.

Description of Read Instruction
Send Format
Return Format
1)
Sending Address
The sending address refers to the local address of the instrument, which can be set in the parameter bus
interface of the communication setting interface of the instrument. The value ranges from 1 to 31.
2)
Function Code
The read command function code is: 0x0F.
3)
High Address
The address is the storage address of the data in the instrument, and the high address is the high eight bits
of the address.
4)
Low Address
The address is the storage address of the data in the instrument, and the low address is the low eight bits of
