Abstract

A method for controlling an automation system having control redundancy is provided. The automation system has at least a first controller, a second controller and a plurality of field devices connected to the first and second controller via a data bus, with the first and second controller configured to cyclically control an automation process of the automation system. The method comprises cyclically controlling the automation process via the first controller, determining a malfunction of the first controller during an (n+x)-th control cycle, where the (n+x)-th control cycle is carried out x control cycles later in time than the n-th control cycle, and sending out an n-th set of output data via a second input-output unit of the second controller to the plurality of field devices in the (n+x)-th control cycle, for controlling the automation process. An automation system is configured to carry out the method.
