US 2002/0171533 A1 · Method for transmitting and receiving messages in home appliance networking system

Abstract

A method for transmitting and receiving messages in a home appliance networking system, wherein a first home appliance connected to a network appends a unique message identification number to a header of a message and transmits the resulting message to a second home appliance connected to the network. Messages transmitted and received among a plurality of home appliances can be distinguished from one another, resulting in a reduction in message transfer errors. Moreover, as needed, a group code corresponding to a specific group of home appliances may be appended to a transmitter message for control of the specific group so that the home appliances can be conveniently and efficiently controlled at one time.
