  • Patent number: 9740382
    Abstract: Methods and apparatus to monitor tasks in a process system enterprise are disclosed. In one example, a method is disclosed that comprises analyzing, using a processor, tasks in an enterprise to determine a criticality of each task and an actionability of each task, ordering, using the processor, the tasks based on the criticality and the actionability of each of the tasks, and rendering, via a display, a first graphic representative of at least a portion of the ordered tasks.
    Type: Grant
    Filed: January 23, 2013
    Date of Patent: August 22, 2017
    Assignee: FISHER-ROSEMOUNT SYSTEMS, INC.
    Inventors: Nathan William Pettus, Navin Rajashekar, Glenn Mclaughlin
  • Patent number: 8825189
    Abstract: Example methods and apparatus to execute an auxiliary recipe and a batch recipe execution are disclosed. A disclosed example method involves executing a first recipe, and before completion of execution of the first recipe, receiving an auxiliary recipe. The example method also involves determining whether the first recipe has reached an entry point at which the auxiliary recipe can be executed. The auxiliary recipe is then executed in response to determining that the first recipe has reached the entry point.

  • Patent number: 8165700
    Abstract: Systems and methods for providing an integrated HMI application for monitoring and interacting with both batch and non-batch processes in a process plant are disclosed. A plurality of independent stand-alone software objects defining various batch process interface views are embedded within a non-batch process control interface application. A blackboard service is provided for storing batch control data used by the various stand alone software objects. The blackboard service may be adapted to communicate with a batch control server to receive batch control data for populating the various batch interface views with data relating to various batch processes being carried out in the process plant and to send instructions for controlling the various batches input by users via the various batch interface views.

  • Patent number: 8150541
    Abstract: Example methods and apparatus to modify a recipe process flow during recipe execution are disclosed. A disclosed example method involves executing a recipe, and before completion of execution of the recipe, receiving process flow change information indicative of a modification to a process flow of the recipe. Process flow rules are then retrieved from a process flow rules data structure. The recipe process flow is modified based on the process flow change information in response to determining that at least one requested change indicated by the process flow change information does not violate one of the process flow rules.
