Abstract

A method for navigating in a process control system. The process control system includes a graphical user interface with a plurality of graphic objects each associated with a process control object wherein a graphic object has an active link for monitoring or controlling at least one physical control object. The graphical user interface is arranged with navigation means so that a user can indicate or select one point in a process section on the graphical user interface as a first user input and increase, in a continuous animated movement, the scale at which the point and its immediate surroundings in the process section are displayed. Further, the zooming-in or zooming out continues displaying a view of the indicated or otherwise selected point on the graphical user interface and scaling it up continuously until a predetermined scale is reached or, until a second user input is received.
