RTU frame format

:

Frame header (START)

Greater than the 3.5-byte transmission idle time

Slave address(ADR)

Communication address:1 to 247(0: broadcast address)

Command code(CMD)

03: Read slave parameters, 06: Write slave parameters

Function code address(H)

It is the internal parameter address of the inverter,
expressed in hexadecimal format. The parameters
include functional parameters and non-functional
parameters (running status and running command).
During transmission, low-order bytes follow the high-
order bytes.

Function code address(L)

If the wrong communication frame was detected by the salve or other

reasons caused the failure of reading and writing, the wrong frame will be
replied.
