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.

Description

technical field [0001] In general terms, the present disclosure relates generally to process control systems and, more particularly, to monitoring trends of process variables and hierarchical, graphical navigation of process control plants. Background technique [0002] Process plants, such as those employed in the chemical, petroleum, or other industries, typically include one or more centralized or decentralized process controllers that are communicatively coupled via analog, digital, or combined analog / digital busses to at least A host or operator workstation and one or more process control and instrumentation devices (such as field devices). Field devices can be, for example, valves, valve positioners, switches, transmitters, and sensors (eg, temperature, pressure, and flow rate sensors) that perform functions in a process (such as increasing or decreasing flow and measuring process parameters). The process controller receives process measurements or process variables o...
