  • METHODS AND APPARATUS TO VIRTUALIZE A PROCESS CONTROL SYSTEM
    Publication number: 20220260961
    Abstract: Methods and apparatus to virtualize a process control system are described. A described process control system includes a server cluster including one or more servers. When operating, the server cluster provides a virtual workstation or virtual server, a virtual controller to interoperate with the virtual workstation or server and to implement process control operations, and a virtual input/output device to interoperate with the virtual controller and coupled to one or more field devices within the process control system.

  • Methods and apparatus to manage process control search results
    Patent number: 10169484
    Abstract: Example methods and apparatus to manage process control search results are disclosed. A disclosed example method includes receiving a search parameter from a user via an application to view search results associated with the search parameter, determining a display context based on the application, searching a search index for control parameters that match the search parameter to form a set of matched control parameters, wherein the search index includes control parameters that correspond to runtime data generated by a controller within a process control system, and rendering the set of matched control parameters for display via the application as the search results based on the determined display context.
