Multiple Views of an Industrial Plant are graphically displayed and viewed. A graphical user interface displays the views in corresponding panes or windows of the graphical user interface. The views, being graphical representations of systems of the Industrial Plant, are coupled by a coupler according to a predetermined relationship between the underlying systems of the Industrial Plant represented by the coupled views. The coupler automatically refocuses the panes to display different views of the Industrial Plant based on a selection of an object in any of the panes or on a manual refocus of one view and on the predetermined relationship for coupling the views. The Coupled views represent different domains of the Industrial Plant or Industrial Network e.g. real-time monitoring and operation, configuration, debugging, maintenance, scheduling, asset management, documentation, training, simulation, physical construction, material flow monitoring, programming, interconnecting function blocks, performance analysis. The analysis may be provided at different points in time (now, past, predicted future) and with a different spatial focus (parts, whole). Coupling different views greatly reduces handling effort for building and operating Industrial Plants.
