摘要:
The invention relates to a method for providing a navigation tool of a user interface for an industrial control system. The control system is arranged with a plurality of process graphics comprising one or more software objects. The software objects are arranged in hierarchical groups each representing a process, part-process or an equipment, in which materials are moved and/or processed in a predetermined order. The navigation tool includes a graphic image or map showing the plurality of process graphics symbolically arranged as a plurality of nodes. Each node is spatially arranged at a given distance from the centre of the map according to a hierarchical relationship between the process graphics, and the map is displayed superimposed on top of the process graphic currently displayed on the workstation. A computer program and a workstation are also described. The node representing the currently open process graphic is shown by a visual indicator.

Systems and methods are provided that allow a user to monitor, diagnose, and configure a process. A user interface may be presented that displays data received from process monitors, sensors, and multivariate models. The user interface may be interactive, allowing a user to select which composite and multivariate models are displayed. The user interface and multivariate model may be constructed and updated in real time. The user interface may present various data and interfaces, such as a representation of a composite variable in a multivariate model, a representation of the contribution of process variables to the composite variable, and a representation of a subset of the process variables. The user may select a point of the composite variable for analysis, and the interface may indicate the contribution and values of process variables at the selected point. The interface may be transmitted to a remote user.

In an apparatus for operating and monitoring a plant, a manipulating device (3) provides the plant with manipulation signals for operating the plant. In response to information supplied from the plant and a manipulating signal of the manipulating device, a first display data producing device (8A - 8G) produces first display data needed for the operation of the plant changing every moment. On the basis of data supplied from the first display data producing device (8A - 8G), a first display device (2) displays information relating to the operation of the plant. In response to information supplied from the plant and a manipulating signal of the manipulating device (3), a second display data producing device (7A, 7B) produces data needed for monitoring the plant. On the basis of data supplied from the second display data producing device (7A, 7B) a second display device (4) displays information relating to the monitoring of the plant on a larger display screen (4A, 4B) than that of the first display device (2). Information displayed by the first display device (2) and information displayed by the second display device (4) complement each other and make it possible to accurately operate and monitor the plant.

The present invention is a method for detecting an abnormal event for process units of an ethylene processing system. The method compares the operation of the process units to a model developed by principal components analysis of normal operation for these units. If the difference between the operation of a process unit and the normal operation indicates an abnormal condition, then the cause of the abnormal condition is determined and corrected.

An operator station for the MOD5E system capable of organizing different sets of sequences from different MOD5E process control computers into one user interface. This multi-monitor computer workstation allows a plant operator to monitor and control the operations of segment of a manufacturing process by acting as the human interface to the MOD5E process control computer. Further, a method for monitoring and controlling the manufacturing process is described.

A computer implemented method of dynamically updating an interactive diagnostic schematic overlay comprises displaying a first drawing comprising a plurality of static graphical objects, each static graphical object corresponding to a design element of a complex system and identifying a diagnostic schematic overlay comprising a plurality of dynamic graphical objects, wherein each dynamic graphical object is aligned with a static graphical object of the plurality of static graphical objects. In an embodiment, the diagnostic schematic overlay further includes a plurality of fields, wherein each field may be populated with one or more dynamic graphical objects, and the method further includes determining a design element operating state and/or a design element operating parameter for at least some of the static graphical objects at a first instance in time and displaying, together with the first drawing, determined operating states and determined operating parameters as an updated diagnostic schematic overlay.

A group management apparatus (30) manages, as a plurality of groups (15a, 15b, 15c), numerous installation devices installed in a plurality of buildings (50a, 50b, 50c). The group management apparatus comprises: an acquiring component (35a) that acquires operating data of the numerous installation devices via controllers (20a, 20b, 20c) that are placed in each building and control the numerous installation devices inside the buildings; a summarizing component (35c) that summarizes, per group, operating data values that are values represented by the operating data; and a screen generating component (35e) that generates a screen in which the results, with respect to the plurality of groups, of the operating data values having been summarized by the summarizing component are juxtaposed.

Example methods and apparatus to conceal portions of a visual object diagram in a process control system are disclosed. A disclosed example method includes receiving a selection to conceal a first functional block within a visual object diagram, wherein the first functional block is associated with a first view parameter, determining a link from a process control parameter within the first functional block to a first intersection within a second functional block within the visual object diagram, wherein the link is associated with a second view parameter, coupling the first view parameter and the second view parameter to the first intersection, and concealing the link and the first functional block.
