  • Methods and systems for providing electronic documentation to users of industrial process control systems
    Patent number: 5918233
    Abstract: In a process control system, a user selects a displayed object. The user then asks to be shown documents related to the selected object. A list of related documents is automatically displayed to the user who may then select a document for display. The association of documents with displayed process control objects is facilitated by a document librarian. Within the document librarian, a user drags documents from within a document hierarchy over to hierarchically designated objects within the process control system, and drops them thereon. Links between the documents and the process control objects are thereby established.
