Claim Text:
1. A power line communication device for controlling multiple machines connected to individual sub-units, said sub-units being controlled by a main unit using power line communication by means of broadcasting, comprising: a controller; one or more main units capable of superimposing control signals containing data from said controller onto the power line; multiple sub-units capable of controlling connected machines by receiving control signals broadcast from said main unit; a means of determination that informs an operator when said sub-units connected to the machines have received control signals; and, wherein each sub-unit is set up to be capable of carrying out data transfers either from the main unit or selected sub-units, said sub-units have ID numbers that differentiate each sub-unit; and said power line communication device is able to designate using an ID number a selected sub-unit to carry out data transfer based on said means of determination during data transfer setup the data transfer setup is such that a main unit transmits control signals to all sub-units via broadcasting; said means of determination is used on each sub-unit or each machine connected to said sub-unit to determine whether all sub-units are controllable; said power line communication device is adapted to execute the following steps: said main unit sends out control signals to sub-units via broadcasting; if there are uncontrollable sub-units, nearby controllable sub-units are selected for data transfer via said ID numbers, and these selected sub-units send out control signals via broadcasting; if there are still uncontrollable sub-units, once again nearby controllable sub-units are selected for data transfer using said ID numbers, and these selected sub-units send out control signals via broadcasting; and repeat until all sub-units are controllable.
