1-8. (canceled)
A redundant automation system for controlling a technical process, comprising:
- a process data of the technical process;
- a master and a standby automation device constructed to generate from the process data:
- an input process image, and
- a respective output process image relating to a plurality of output signals of the automation system;
- and
- a computer-aided monitoring device that determines a comparison process image relating to the number of output signals of the automation system;
- and
- a communication connection that connects the computer-aided monitoring device to the master and the standby automation devices that transmits the input process image to the monitoring device.
