PROBLEM TO BE SOLVED: To provide a power line communication device, capable of controlling a multiplicity of subunits without omission from a master unit using broadcast.SOLUTION: The power line communication device controls each device connected from the master unit to each subunits through a plurality of subunits by power line communication using broadcast. The power line communication device includes: a controller; the master unit, connected to the controller, for superposing a control signal including data from the controller; and the plurality of subunits for receiving broadcasted control signal from the master unit to control each connected device. Each subunit is configured to be transferrable of data, and can transfer data from the master unit or a selected subunit. |
