Function code 03 – Read register
Request Response
01 : Address 01: Address
03 : Function code 03 : Function code
00 : Register address higher 04 : Quantity of bit
00 : Register address lower (display the address) 80 : Date 1
00 : Register number higher 04 : Date 2
02 : Register number lower 80 : Date 3
CRCL : CRC Parity code lower 80 : Date 4
CRCH

CRC parity code higher CRCL : CRC Parity code lower
CRCH
：
CRC parity code higher
Note: To read a float date, the quantity of the register addresses and their values have to be even,
or reponse will be error.
Function code 04 – Same as function code 03
Function code 06 – write one register
