Abstract: A batch event historian gathers, stores and presents data regarding a batch process where relationships among the various elements of data are automatically derived by an executive program. A persistent store includes structure corresponding to the relationships defined among procedural elements and equipment in accordance with batch processing industry S88.01 standards. The executive program gathers event information generated by the batch process and derives the relationships among the events in accordance with these industry standard models. Storage and corresponding retrieval and presentation of such historical data is thereby simplified for a user because the user need not manually configure the historian programs to derive the relationships. Association of any continuous data log with event information is automated thereby obviating the need for manual configuration by a user to establish such associations.

Abstract: A method and apparatus for the integrated display of process events and trend data. The method and apparatus provide for a unified display of trend data and process events related to the control and/or monitoring of a manufacturing process. A workstation generates and displays a trend chart that represents values of one or more selected process parameters during a selected time window. The workstation also generates and displays an event table containing information describing process events that are related to the selected process parameters and that occurred during the selected time window.

Abstract: A process control system includes an alarm and event monitoring and display system for which various users of the system can easily prioritize the alarm and event information that is displayed. The alarm and event configuration is highly flexible and is configured by a user to display particular events in a hierarchical manner, as directed by the user. The user sets a desired alarm priority, selecting high importance alarms for more urgent display and annunciation and rendering a lower display status to less urgent events. At log-on, a particular system user is associated with a display configuration for displaying alarm and event information that is pertinent to that user and the process control system is automatically "primed" with current alarms and initiate process information about new alarm and event occurrences.
