Abstract
A communicative control system includes a central control apparatus and a terminal that is remotely controlled according to messages communicated by the central control apparatus . Before communication is commenced, the address storing unit of the terminal stores a provisional address, while the unique terminal information storing unit stores unique terminal information. When commencing communication, the central control apparatus uses the provisional address to specify the terminal with which communication is to be performed. The central control apparatus compares the unique terminal information stored in the unique terminal information storing unit in the terminal with the unique terminal information that is stored in advance in the unique terminal information storing unit and is associated with a proper address stored in the address storing unit . Depending on the result of the comparison, the central control apparatus then has a corresponding proper address stored in the address storing unit of the terminal
