SYSTEM AND METHOD FOR VISUAL PRESENTATION OF INFORMATION IN A PROCESS CONTROL SYSTEM

摘要

Various graphical displays used for visualization of control techniques in a process control system can be provided to an operator. For example, the graphical display could include an image (224) associated with a portion of a process and icons (602, 608, 614, 638) that are associated with corresponding process variables. At least some of the icons (638) include a symbol that represents a change of one value of the associated process variable relative to another value of the process variable. Another graphical display could include a pigeonhole display (1200) that includes visual elements (802, 810, 814) associated with corresponding process variables. Selection of a visual element could present the operator with a peephole display (1000) that includes information associated with process variables associated with the selected visual element. Each visual element (900) displays layers (902, 904, 906) of information that are associated with its process variable.
