User configurable alarms and alarm trending for process control system
First Claim
1. A graphical user interface for a process control system that includes a plurality of data inputs and a variety of alarms for said data inputs, the interface comprising:
- a main panel display including a plurality of alarm indicators, wherein each of the alarm indicators includes a visual representation of an active alarm for a data input from one or more of a control module, an equipment module, or a processing unit and provides indicia of alarm priority and alarm age; and
an alarm profile display providing contextual information corresponding to a selected one of the plurality of alarm indicators wherein the contextual information includes another alarm indicator to which the selected alarm indicator is a parent, the alarm profile display including a plurality of alarm profiles wherein active alarms are grouped by at least one or more of time span, plant area, process unit and equipment module, andwherein the alarm profiles are super imposable on a process graphic display so that alarm profiles can be seen in the spatial context of equipment schematics depicted in the process graphic display.

Abstract
Various graphical displays for plant process operators are provided which combine aspects of alarm priority and alarm age to assist operators in making better choices in responding to alarms. The disclosed graphical displays provide improved contextual information about specific alarms and the relationships with other alarms in the same control module, equipment module, etc. Hierarchically organized presentations of active alarms and alarm age profiles are also provided to assist operators in evaluating causes of “alarm floods” in chain reactions within complex process environments. Various types of alarm or display alerts are also provided for improved monitoring of processed conditions and changes in process controls.

18. A method for generating a graphical user interface for a process control system that includes a plurality of data inputs and a variety of alarms for said data inputs, the method comprising:
-
displaying a main panel display including a plurality of alarm indicators, wherein each of the alarm indicators includes a visual representation of an active alarm for a data input from one or more of a control module, an equipment module, or a processing unit and provides indicia of alarm priority and alarm age, displaying an alarm profile display in response to selecting an alarm indicator from the main panel display, the alarm profile display providing contextual information corresponding to the selected alarm indicator, wherein the contextual information includes another alarm indicator to which the selected alarm indicator is a parent, the alarm profile display including a plurality of alarm profiles wherein active alarms are grouped by one or more of time span, plant area, process unit and equipment module, and superimposing the alarm profiles on a process graphic display so that the alarm profiles can be seen in the spatial context of equipment schematics depicted in the process graphic display. - View Dependent Claims (19)
