Abstract

A redundant automation system having a plurality of automation devices which are connected to one another comprises a plurality of master devices and a slave device. Each of the plurality of automation devices processes a control program in order to control a technical process. At least one of the plurality of automation devices operates as a slave and at least two of the plurality of automation devices, each operates as a master. The plurality of master devices is each configured to run a respective master program and to process processing sections of the respective master program of the respective master program, and the slave device is configured to process a corresponding slave control program for each master control program run by the plurality of master devices and, if one of the plurality of master devices fails, to assume the function of the failed master.
