Description

technical field

[0001] The invention relates to a redundant automation system for controlling a process plant and a method for operating such an automation system, which has at least two automation devices. Here, the first automation device acts as the main automation device and the second automation device acts as the backup automation device. Background technique

[0002] In the automation of process plants, especially power plant plants, one of the most important requirements is the long-term availability of plants and systems. For reasons of excluding possible hazards and for the reliable supply of electrical energy or products, interruptions of automation systems and the resulting downtimes of important technical equipment must be avoided as much as possible.

[0003] In order to solve this problem, so-called high-availability automation systems are known in the prior art, such as SIMATICS-7H of Siemens, in which all actual components including memory and power supply ...
