Abstract

Methods and systems for providing knowledge access in a process control system and methods and systems for providing dynamic hyperlinks in a process control system are disclosed. A dynamic hyperlink may define an association between a process control object corresponding to a process control element and a knowledge object corresponding to a knowledge reference stored internally or externally to the process control system. At a run-time of a display view that includes the process control object, the defined dynamic hyperlink may be established without a configuration or a download. Upon selection of the defined dynamic hyperlink, the corresponding knowledge reference may be displayed. Defined dynamic hyperlinks may be stored in a process control system database independent of process control objects or knowledge objects. Embodiments of user interfaces for administrating dynamic hyperlinks are also disclosed.
