Apparatus and method for providing a pan and zoom display for a representation of a process system

摘要

A method includes displaying regions in a graphical display. At least two regions correspond to different portions of a representation of an industrial process system. A thumbnail region corresponds to an entirety of the representation of the process system. A viewport region corresponds to a portion of the representation of the process system less than the entirety of the representation of the process system. The viewport region is disposed and movable within the thumbnail region. A current view region corresponds to a current view of the representation of the process system. The current view is associated with the viewport region. The method also includes, responsive to user activation, moving the viewport region within the thumbnail region and updating the current view region. The thumbnail region is configured to identify at least one fault condition indicator outside the viewport region.

1. A method comprising:
displaying a plurality of regions in a graphical display, at least two of the regions corresponding to different portions of a representation of an industrial process system, wherein the regions include:
a thumbnail region that corresponds to an entirety of the representation of the process system, wherein the thumbnail region comprises a thumbnail viewport identifying a first viewable area defined by a boundary disposed and movable within the thumbnail region that corresponds to a portion of the representation of the process system that is less than the entirety of the representation of the process system; anda current view region that corresponds to a current view of the representation of the process system, wherein the current view is an enlarged view of the first viewable area defined by the thumbnail viewport, and wherein the current view region comprises a clickable hyperlink hotspot that defines a current viewport defining a second viewable area; responsive to a first user activation, moving the thumbnail viewport within the thumbnail region and updating the current view region; and when the clickable hyperlink hotspot is selected, displaying the second viewable area in the current view region and adding a nested region configured to display the first viewable area, wherein the nested region comprises the current viewport; wherein the thumbnail region is configured to identify at least one fault condition indicator outside of the current view and the thumbnail viewport.
