Abstract
Various graphical displays used for visualization of control techniques in a process control system can be provided to an operator. For example, a graphical display could include (i) an image associated with at least a portion of a process and (ii) one or more icons identifying one or more process variables associated with at least the portion of the process. Selection of an icon could present the operator with a faceplate containing information associated with at least one of the process variables. Another graphical display could include (i) a focal variable symbol identifying a focal process variable and (ii) one or more additional variable symbols identifying one or more additional process variables associated with the focal process variable. Gains associated with the additional process variables could be identified in the display. Yet another graphical display could be used to remotely invoke and control applications executing in a process control system.
