AI Technical Summary

Technical Problem

Existing redundant automation systems cannot seamlessly obtain and store dynamic runtime data during synchronization, resulting in data loss or need to be temporarily stored, affecting the high availability and efficiency of the system.

Method used

A data coordination organization is designed to ensure the latest and completeness of the data by writing status information into two files during the data collection phase and allowing write access to only one file during the synchronization phase until the data is successfully delivered. It will be further stored and passed.

Benefits of technology

It realizes seamless acquisition of persistent data during synchronization, reduces the complexity of control programs and test costs, and ensures high availability of the system and data integrity.

Abstract

The invention relates to a redundant automation system and a method for operating the same, comprising a first subsystem and a second subsystem, each having a control program for controlling a technical process and being implemented in the same manner, there is a synchronization connection between the first subsystem and the second subsystem in order to acquire dynamic runtime data, it is proposed that the first data coordination mechanism has a first file and a second file, the first data coordination mechanism is implemented to write state information into the first file and the second file during a data collection phase, -the first data reconciliation mechanism keeps the dynamic runtime data up to date by write access to the first file and the second file and blocks further write access to the second file at the beginning of the synchronization phase and allows only write access to the first file and also transfers the blocked second file to the second subsystem.
