Method and device for monitoring control systems

Abstract

A method for monitoring control systems, a device for monitoring control systems and a corresponding computer program product, wherein the control system has at least one communication network and at least two communication end points connected to the communication network, which communication end points exchange data via the communication network, wherein the data exchanged between the communication end points is acquired and after comparing the currently acquired data with previously acquired data, an alert is raised when new data is acquired. As a result, a monitoring is provided which recognizes errors particularly quickly and reliably in the context of communication in control systems, in particular in industrial control systems. These errors may subsequently be coupled with a quality management to determine whether quality losses correlate with such recognized errors.
