METHOD AND SYSTEM FOR PROVIDING AN HMI IN A PROCESS CONTROL SYSTEM FOR MONITORING AND CONTROL OF A PROCESS

摘要

The invention provides a method for navigating in a process control system. The process control system comprises a graphical user interface with a plurality of graphic objects each associated with a process control object wherein at least one 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 at least one point (+) in a process section on said graphical user interface as a first user input and increase, in a continuous animated movement, the scale at which the at least one 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 said graphical user interface and scaling it up continuously until a predetermined scale is reached or, until a second user input is received. At that stage the a scaled-up view of the indicated or otherwise selected at least one point (+) is displayed at the scaled-up level.
