Embodiment Construction

[0030] figure 1 A redundant automation system 1 according to the invention is shown, comprising automation devices 3a and 3b. In this case, the first automation device forms the master automation device 3a, which takes over the control of the process plant. Signals from the process equipment and control commands to the process equipment are processed here by the field device 17 and transmitted via the field bus 15 to the automation devices 3 a and 3 b.

[0031] In the event of a failure of the first automation device 3a, a second automation device is available as a backup automation device 3b and can assume the control tasks of the first automation device 3a.

[0032] A monitoring module 23 is provided for fault detection and switching from the first automation device 3 a to the second automation device 3 b. The monitoring module 23 analyzes the life characteristics 25 of the first automation device 3a and switches to the second automation device 3b in the event of a failure...

Abstract

The invention relates to a redundant automation system (1), and a method for operating one such automation system (1). The inventive automation system comprises two automation appliances (3a, 3b) with which a common memory unit is associated, on which status data of the automation appliances (3a, 3b) can be stored. In this way, the automation appliances (3a, 3b) have direct access to a common database and a memory compensation is dispensed with in the event of an error during the switchover to the standby automation appliance (3b).

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 ...
