Abstract

A method for operating a redundant automation system for controlling a technical process in which two-out-of-three system with three subsystems are operated, wherein a comparator is cyclically operated in each subsystem and compares the first, second and third output data with one another, and a respective comparator is operated such that, during each comparison in which the result is that all output data are approximately the same, no further action is performed, and during a comparison in which deviations between the output data are determined, that subsystem in which the deviations of its own output data from the other output data are the greatest is identified as faulty via a majority decision.
