PLUG-AND-PLAY POWER LINE COMMUNICATION DEVICE

摘要

The present invention provides a power line communication device wherein a home code or a device address of each device can be set or changed automatically or easily by oneself by a user upon installation of the device and the set or changed contents can be informed to the other devices upon installing the device. The power line communication device can communicate with at least one external device through the power line, and performs processes of searching, changing and informing the address through the Hail communication performed by a program. The power line coupler couples a signal transmitting and receiving means with the power, and the signal transmitting and receiving means transmits and receives signals through the power line via the power line coupler. A controlling means controls the signal transmitting and receiving means. A storing means stores program codes for driving the controlling means. The program codes according to the present invention comprises a device code managing means for searching a device so as not to be overlapped with the device code of the external device. In addition, the program codes may further comprise a home code managing means for searching a home code of the external device, and setting it as an own home code.
