Abstract

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.
