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.
