Abstract

PURPOSE: To improve the reliability of information with a simple constitution by connecting several central processors via data transmission interfaces and then by collating information to be collated through software.
CONSTITUTION: Microcomputers 101 (systemI) and 102 (system II) fetch input data from controlled unit 190 via input-output circuit 180 and digital input interfaces 141 and 142 of both the systems, and gather and edit (401a and 401b) them in a required format. Those edited data of both the systems are transmitted by series- data transmission interfaces 161 and 162 and collated by programs of both the system to make correction at need, thereby obtaining coincidence (402a and 402b). Next, originally-aimed control logical operation for controlling a controlled unit is carried out (403a and 403b) and the output data are collated (404a and 404b) between both systems as well as input data, so that when data of both the systems agree, output data will be outputted (405a and 405b) to interfaces 151 and 152 respectively.
