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.
Claims24
A method for displaying process information in a process control and/or monitoring system comprising a workstation having a display screen, a controller and an I/O subsystem, said workstation executing the steps of:
- generating and displaying on the display screen a trend chart containing values of one or more selected process parameters during a selected time window based on a user-defined trend chart configuration;
- and
- generating and displaying on the display screen an event table containing information describing process events that are related to the selected process parameters and that occurred during the selected time window, such that the event table and the trend chart may be viewed on the display screen at the same time.
A process control and/or monitoring system comprising:
- a process controller;
- an I/O subsystem;
- and
- a workstation having a display screen, said workstation comprising:
- means for generating and displaying on the display screen a trend chart containing values of one or more selected process parameters during a selected time window based on a user-defined trend chart configuration;
- and
- means for generating and displaying on the display screen an event table containing information describing process events that are related to the selected process parameters and that occurred during the selected time window, such that the event table and the trend chart may be viewed on the display screen at the same time.
A graphical user interface for displaying trend and event data related to the operation of a process, the interface comprising:
- a first display area configured to display at least one trend line representative of at least one parameter associated with the process;
- a second display area configured to display information representative of at least one process event;
- and
- event markers related to the at least one process event and displayed on the first display area.
A system for monitoring a process comprising:
- an event database containing event records related to the process;
- a trend database containing historical trend data related to the process;
- means for simultaneously displaying a trend graph representing at least a portion of the historical trend data and a table representing at least a portion of the event records, wherein the table displays event records related to the portion of the historical trend data being displayed on the trend graph.
A system to coordinate and display information related to a process variable comprising:
- a workstation including a display screen;
- a first display region on the display screen that displays process trends related to the process variable;
- and
- a second display region on the display screen that displays a table of event records related to the process variable.
