and COM.
Communication protocol conforms to MODBUS RTU protocol. In instruction table register number is
register address.
Composition of communication information: Address code - Function code - Data segment - CRC, A
message is sent and received continuously, and the character interval cannot be greater than one
character, otherwise it is regarded as the beginning of a new message or the end of the previous
message. The message body consists of hexadecimal numbers.
