Abstract: The invention relates to a system for generating and displaying messages and/or alarms particularly in an automation system of a plant and/or process. The invention further relates to a corresponding method. Using the system and method, messages and/or alarms can easily be displayed differently depending on the state of a production plant or process.

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.

Abstract: A display and operating device (A) that has a touch-sensitive display unit (B) for outputting display objects (AZ, K) and has a processing unit such as a graphics card (G). This processing unit has a first component that processes display data of a first display object that represents a technical process and a second display object that simulates an on-screen keyboard (K) with keyboard elements (T), and has a second component that superimposes the first and second display data in such a manner that the on-screen keyboard and the first display object appear transparent on the touch-sensitive display unit. A third component of the processing unit detects an input position (P) on the touch-sensitive display unit, while a fourth component associates the detected input position with a keyboard element and initiates an action associated with this keyboard element.
