Abstract
An alarm display and interface tool for use in a process control system receives and displays different categories of alarms, including for example, device alarms and hardware alarms as well as traditional process alarms, on a single display to enable an operator or other user to view and have access to these different categories of alarms. The display and interface tool may be used to filter the alarms that are displayed according to any number of categories, including the category of the alarm, the priority of the alarm, the status of the alarm, etc. so as to alternatively segregate or combine the tasks typically associated with operator, maintenance and engineer personnel. The tool may also be used to access each of the displayed alarms to obtain more information about any individual alarm.
