Abstract

PURPOSE:To prevent breakdown of a system, by connecting each communication control device to which an apparatus to be controlled is connected by a loop transmission line, and sharing an editing function among each communication control device. CONSTITUTION:As for each communication control device 11-1N, its transmission sequence is prescribed in advance, and all the information of each communication control device 11-1N is loaded on a loop line one after another and is transmitted. Also, information to be received by each communication control device 11-1N is prescribed in advance by the system, collating of an address bit in the start byte, and counting of the number of bytes in the data byte are operated, only the information required for the device concerned is received selectively, and an apparatus to be controlled A is controlled. According to such a constitution, even if a specific communication control device becomes faulty, other communication control device is operated normally, and no breakdown of the whole system occurs.
