International Classification:

G05B 13/02

US Classification:

700 29, 700 52

Abstract:

Disclosed is a method of controlling and managing a process control system having a plurality of control loops. The method includes implementing a plurality of control routines to control operation of the plurality of control loops, respectively. The plurality of control routines may include at least one non-adaptive control routine. Operating condition data is then collected in connection with the operation of each control loop of the plurality of control loops, and a respective process model is identified for each control loop of the plurality of control loops from the respective operating condition data collected for each control loop of the plurality of control loops. In some embodiments, the identification of the respective process models may be automatic as a result of a detected process change or be on-demand as a result of an injected parameter change.

International Classification:

G06F 17/00

US Classification:

706 45

Abstract:

A method of managing a process model history having process models stored therein, includes organizing the process models according to first and second priority criteria, wherein each process model is represented according to a combination of a value in connection with the first and second priority criteria. The representation may be coordinate values in a multi-dimensional space having dimensions corresponding to the first and second priority criteria. A degree of separation or relationship to a common point of reference is calculated for each process model, where the point of reference is a value in connection with the first and second priority criteria. A process model may be removed or selected for deletion based on the degree of separation or proximity in relation to the point of reference, subject to the total number of process models identified for the same control routine, and the total number of process models identified for the same operational region.

Abstract:

Methods, systems, and computer-executable instructions for event synchronized reporting in an process control system are disclosed. Events may be synchronized by a synchronization parameter, whose instances of occurrence may be non-contiguous in time. Examples of synchronization parameters may include a work shift, a work group, an individual's on-duty time, a logged-on period of an individual, the execution times of a process control entity, a batch run type, and a procedure or sub-unit of a batch run. Instances of occurrence of the synchronization parameter may be recorded into a process control event database. Event synchronized reports may contain at least one synchronization value based on both the instances of occurrence of the synchronization parameter as well as historical process control data. Data from various historian databases may be accessed from process control system tools and integrated into a single report.

US Classification:

386124, 348 86, 348E07085

Abstract:

A process control system user display provides a display image containing control system information. The system may include a digital recording module including an image capture module for making a real-time digital recording of at least a portion of the display image, the image capture module buffering a terminal portion of the real-time digital recording. A storage module may store at least a portion of the real-time digital recording. A real-time digital recording may contain at least a portion of the display image, wherein, at any particular time, the real-time digital recording includes information from the control system for a predetermined duration proximate the particular time, and at least a portion of the real-time digital recording may be stored. A desired portion of the digital recording may be played back, optionally with process control system event and/or continuous history.

US Classification:

715205, 715843

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.

Abstract:

Methods and systems for providing dynamically linked graphical messages in a process control system are disclosed. A dynamically linked graphical message may include a hyperlink and an electronic sticky note image. At run-time of a display view, the hyperlink may be established between contents of the electronic sticky note image and a process control object, and the electronic sticky note image may be displayed proximate to a representation of the process control object. The electronic sticky note image may automatically be displayed on any display view (displayed on any computing device in communication with the process control system) that includes a representation of the process control object or corresponding sub-class object. The contents of the electronic sticky note image may be stored separately from configurations of the process control object and the display view. User interfaces for administering and displaying properties of dynamically linked graphical messages are also disclosed.

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.
