Abstract:
A system management human-machine interface application for use in a process control system is described herein that enables users to view/monitor information regarding system status and performance and to initiate changes to the operation of system equipment, checkpoint control stations and execute diagnostics. A system management graphical user interface (GUI) includes a number of interface features that enhance the accessibility of system status information to users. Such enhancements include rendering selectable diagnostic information (e.g., online/offline status) on a system component navigation view. The GUI also provides access to a variety of system information including: alarms, messages, watched system management parameters, and a legend for symbols displayed in a system management navigation tree. Other enhancements include: a search function for quickly locating a device in the system to render detailed information, a navigation tree that displays equipment status via icons, and propagating fault statuses up to a highest level of the navigation tree.
