The invention relates to a method, a computer program product and an engineering system for creating a diagnostic model of an automation system made up of various automation components. The diagnostic model is generated automatically during the project planning phase of the automation system. Within the diagnostic model the automation components are represented by model nodes. Functional and/or physical relationships between the automation components are mapped by links between the corresponding model nodes within the diagnostic model. Each model node contains status information in which the status of the associated automation component is stored. By evaluating the status information, the status of the automation system can be investigated and monitored with the aid of the diagnostic model.

Diagnosis of an automation system

A device used for control or monitoring of a process is updated without interruption or exceeding upper response time limits for response to a change in the state of the process. If the updating task requires too much run time, the updating task is terminated. As soon as the updating task has been terminated, a configuration is established again with regard to the control or monitoring of the process, so that it is possible to respond again to changes in the state of the process.
