In general, home networks based on LnCP use a power line as a data transmission medium and connect various digital home appliances including digital refrigerators, digital air conditioners and digital washing machines to a power line through a PLC (Power Line Communication) modem. The operation can be controlled while transmitting predetermined data.

Since the power line is shared by all generations, the communication content of one generation may be transferred to another neighboring generation. Therefore, LnCP introduces a house code to distinguish each generation in order to prevent the communication of each generation from passing over to the neighboring generation.

In addition, the home network is pursuing Plug and Play (PnP), so when the user connects the digital home appliance to the home network, the user can automatically set the logical address of the digital home appliance without additional installation work. However, due to the nature of power lines shared by all households, the logical address of a digital home appliance may be incorrectly assigned by another neighboring household when the logical address of the digital home appliance is automatically assigned.

Therefore, in the home network based on the conventional LnCP, a home network manager for managing a PLC modem and digital home appliances is provided, and the home network manager stores a house code in the PLC modem so that predetermined data is transmitted through the power line. If the PLC modem determines whether or not the house code in the data matches a pre-stored house code, the PLC interface interfaces the data if the house code matches, and interfaces the data if the house codes do not match. The home network manager must assign logical addresses so that digital appliances can communicate with each other. The house code you entered and User interface functions for storing and assigning logical addresses to PLC modems and digital home appliances, managing assigned logical addresses, entering user's operation commands, and notifying the user of the setting status of the home network through the screen. In doing so, the home network manager stores house codes in a plurality of PLC modems and sets logical addresses of the plurality of digital home appliances.
