  • Directly connected display of process control system in an open systems windows environment
    Patent number: 5598521
    Abstract: In a display for a process control system, the display can be generated by one of two different sources, but is controlled by only one of them. A process control system network provides a first source of display, while a windowing system provides a second source. The control system network provides crucial information to the display regarding the operation of the process control system. Alternatively, the windowing system allows displays to be generated from a variety of sources including external computer systems. The windowing system controls the display by opening and maintaining windows. One specific window to be opened is a window in which the control system network can display information. To allow the control system network to communicate information, a window is opened by the windowing system, and then the process control network is allowed to overwrite information into this newly opened window. Also, should the windowing system fail, control of the display is given to the control system network.
