Abstract
An alarm significance mapping method assigns the subset of parameters and their alarms considered to be of a safety-critical nature in an industrial control system and displays that subset on an apex screen display and other selected appropriate displays, such as a touch-responsive display in the form of alarm icons for presentation to the system operators. Each alarm icon on the `apex` display is coupled or concatenated to other displays through a display page hierarchy so that the operator, by selecting a particular alarm icon on the `apex` screen, can follow the alarm `thread` through the multi-level display page hierarchy to the ultimate condition or conditions that cause an alarm on the `apex` screen.
Claims8
A significant-alarm display system for an industrial control system having a plurality of monitored alarm objects defined by parameters, components, and subsystems and alarm conditions associated therewith, a subset of the monitored alarm objects having a predetermined criticality to successful operation of the industrial control system and having a video display system for displaying information on a display surface, the video display system responsive to actuation of a selected portion of the display surface by touching, the system comprising:
- an apex display screen presenting an iconic representation of each monitored object of the subset of monitored objects having a predetermined criticality to successful operation of the industrial control system, and
- at least one additional screen accessed by actuation of a selected iconic representation of the apex screen, a touch of an iconic representation of an alarm condition relating to a monitored objecting causing a transfer by appropriate navigation aids to a second screen to locate a root cause of the alarm on the most desirable display page.
A method far displaying significant alarms in an industrial control system having a plurality of monitored alarm objects defined by parameters, components, and subsystems and alarm conditions associated therewith, a subset of the monitored alarm objects having a predetermined criticality to successful operation of the industrial control system and a video display system for displaying information on a display surface, the video display system responsive to actuation of a selected portion of the display surface by touching, the method comprising the steps of:
- displaying, on a video display surface, an iconic representation of each monitored alarm object of the subset of monitored alarm objects having a predetermined criticality to successful operation of the industrial control system, and
- providing access to at least one additional screen by appropriate navigation aids by actuation of a selected iconic representation on the first-mentioned display to cause a transfer to at least one additional screen to locate a root cause of an alarm condition.
