Abstract

PURPOSE:To enable to save the hardware for each talker, when a number of the same talkers are connected, by enabling the substitution of the function of talker without losing the standard protocol on a common bus. CONSTITUTION:In making talker substitution request from a talker to a specific device, a talker selected and designated designates the name code of a specific device which executes the substituting processing with a listner designation 121 without designating the listener name code of the correspondencer and makes the request of talker substitution. The specific device receiving this talker substitution request 125 designates the listner communicated by the requested talker at the listner designation 122 via a polling 101 and talker designation 111 and makes communication 131 succeedingly. Thus, a controller 19 can substitute the talker function of a talker 29, allowing to simplify the hardware of the talker 29.
