Embodiment Construction
[0048] Process information or process graphics for a process or for an entire plant or facility can be organized according to different criteria and can be statically organized or dynamically changed by the system or the user. The present invention creates and provides a scaling or zoomable graphical interface of process information, process graphics, and related information for a Human Machine Interface (HMI) of a process control system. In particular, process information in an HMI is visually organized on a series of infinite visual planes, each of which can be seamlessly, continuously and smoothly navigated. The key point here is that navigation actions are implemented and represented as continuous and seamless animated movements, because these continuous types of movements help the operator understand where different process information is in the system, providing Directions, distances, and other visual or functional cues.
[0049] Furthermore, by providing zooming in as ...

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.
Description
technical field [0001] The present invention relates to providing an improved operator interface and navigation tool in a user interface in an industrial control system or a process control system. In particular, it relates to a method and system for providing a graphical user interface or Human Machine Interface (HMI) in a process control system for monitoring and controlling a process. Background technique [0002] Computer-based control systems are widely used in many different industrial environments, such as pulp and paper processing and oil and gas generation processes, as well as power generation processes. There is a continuing and generally increasing need for information related to plant capital equipment, current and historical process data, trends, etc. for performing process control, monitoring and control of industrial plant and production equipment. Typically, this information is provided by a control system, usually in the form of one or more distributed con...
