Abstract
A method for signal transmission and reception by a bidirectional bus system in which plural devices performing the communication of a command and a request are interconnected over a bidirectional bus includes the steps of providing a frame of a transmission signal on the bidirectional bus the frame including an address field for designating addresses of communicating devices and a data field for designating the command or request to be transmitted, and inserting the discrimination information for discriminating between the command and the request at a pre-set position in the data field. The transmission signal including the discrimination information is transmitted over the bidirectional bus to other devices. A communication system employing such a bidirectional bus system is also provided.
