Abstract

A process control monitoring system for a process control plant uses graphic trend symbols to assist in detecting and monitoring trends of process variables within the process control plant. A graphic display application within the process control monitoring system may implement and display each graphic trend symbol to graphically indicate or encapsulate current trend and value information of a process variable within the process control plant. The graphic display application may display the graphic trend symbol in a spatially realistic location within a graphical representation of the process control plant while maintaining the hierarchical structure or each hierarchical level of the process plant. The graphic display application may also include a navigation pane and a zoom feature that enable a user to quickly drill down through tend data to obtain more information and to support problem identification and diagnosis tasks.

5. The method of claim 1, wherein receiving the selection of a first equipment selector icon in the equipment selection area includes receiving the selection via a command from a user interface.

6. The method of claim 5, further comprising:

displaying, in response to receiving the selection of the first equipment selector icon in the equipment selection area, a subsection of the graphical depiction of the process control plant associated with the first corresponding equipment of the first unit in the process control plant corresponding to the selected first equipment selector icon in the graphical depiction of the process control plant.

7. The method of claim 1, wherein displaying the one or more equipment selector icons includes displaying an alarm identifier within each of the one or more equipment selector icons, each aggregate alarm identifier comprising two alarm indicators that are associated with the corresponding equipment selector icon, each of the alarm indicators displaying alarm information that is aggregated from alarms associated with the corresponding equipment in the graphical depiction of the process control plant associated with the corresponding equipment selector icon, the alarm indicators indicating a number of alarms at each priority level.

8. The method of claim 7, wherein displaying alarm information includes displaying one or more types of alarms associated with the corresponding equipment in the graphical depiction of the process control plant.

9.
