The management and transmission of events from a server to at least one client via a communication connection includes a server that has at least one server event service communicating with at least one client via a communication connection and at least one unit interface communicating with the at least one server event service. The client includes at least one client event server communicating with the server via the communication connection. Logging of possible events takes place in both the client event server and the server event service. Incident events are passed from the unit interface to the server event service. A client event service initiates requests to the server event service and, based on a submitted request to the server event service, the recorded events are transmitted to the client event service. Events received from the client event service are transmitted to a client application.

Method and system for event transmission

A system is suitable for carrying out a method for the automated processing of fault hypotheses in a course of a fault cause analysis in the case of a fault event in a technical installation. A data processing system uses knowledge-based models for fault cause analysis and physical models of installation functions and processes that can be carried out by the technical installation. The system has a first unit for calculating and storing installation and process states. The first unit has access to the physical models and to data that is stored in a data server for the technical installation. The system has a second unit for hypothesis processing and an input/output device.

Method and system for automatically verifying fault hypotheses predetermined by a user

A method and system for generating an XML-based fault model for fault case analysis, i.e., fault events in industrial plants includes a data entry device connected to a word processor belonging to a data processor having access to a template memory and being connected to a first fault model memory, by which measures the data entry device is set up for data entry for compiling a fault model as a Word document and for storing the document in the model memory, a translator accessing the model memory and connected to a schematic memory storing XML types produced by transferring a template in the template memory into XML types, a second fault model memory storing XML instances produced by translating the document, and an XML engine accessing the schematic memory and the second memory and displaying an XML-based fault model stored therein through a display device and a web browser.

System and method for generating an XML-based fault model

A system and method for supporting a fault cause analysis in a afault event in a plant includes a data processor with memory storing a fault model of XML files accessed by a fault cause navigator and an operating/display device. Each fault model contains an industry-specific process model divided into process steps, with steps and defined fault events needed therefor assigned to plant components/systems, and fault trees assigned to fault events and having fault hypotheses. A checklist with symptoms for verification of the fault hypothesis is assigned to the fault hypotheses. The system enables navigation to the relevant step in the process model by the display and navigator, and presents a fault event list. Following fault event selection, critical components/systems corresponding thereto are found and displayed. Possible symptoms are generated and displayed in a checklist and hypotheses of possible fault causes, contained in the fault trees, are found and displayed.
