Abstract

PURPOSE:To enable the use and selection of buses according to the degree of emergency and to make the common bus applicable over a wide application, by preparing two levels of 0, 1 by communication types, through making usable for general-purpose by clarifying specifications specific to the common bus. CONSTITUTION:A bus controller CTL having functins such as control of communication level, monitor of failures and selection of usage of a bus IP is connected to the common bus IP of a bus control section, and the functions of the controller CTL are shared into a talker function and a listner function. The functins of talker, listener and talker/listener are connected to a user device sectin having each user device via an IPB control section. This IPB control sectin makes the information conversion and communication processing with the bus IP, and the interface operation of the common specifications of the bus IP is made by the control of talker and listener. The specificatins specific to the bus IP are clarified at the talker, listener and IPB control section, levels 0, 1 are prepared by communication types, and the bus IP is applied to a wide application.
