  • Patent number: 11467720
    Abstract: Techniques for presenting historized process parameter values in a process plant include presenting, via a user interface of an operator application, indications of process control elements in a first display region within a layout of a display view. Each of the process control elements is associated with one or more process parameters. The operator application also presents a trend display view in a second display region within the layout of the display view. The trend display view includes sets of historized process parameter values for process parameters presented in the first display region. For example, the trend display view in the second display region is linked to the display view in the first display region. In this manner, the trend display view presents charts or other graphical depictions of historized process parameter values for process parameters included in the first display region.

  • Patent number: 11467545
    Abstract: The disclosed systems and techniques enable dual mode operation for model-based controllers in which the controllers are capable of operating in both (i) a constrained solution mode, and (ii) an unconstrained solution mode. The dual mode operation improves control because it enables the use of constrained solution mode operation when possible (constrained solution mode often enables superior control) and enables the use of unconstrained solution mode when constrained solution mode is not possible (e.g., when it is impossible to develop the constrained solution with the time available). This enables superior control when compared to typical model predictive control (MPC) controllers.

  • Patent number: 11436242
    Abstract: An edge gateway system securely delivers and exposes data generated by and/or related to a process plant for consumption by external systems, and includes an edge-facing component that receives process plant-related data from a process plant via a field-facing component of the system. The received data may comport with an exposable data type system utilizing a syntax known to the external systems. The edge-facing component stores the received data in a data lake, and mines the data lake to thereby discover relationships between stored data points. Indications of the received data and the discovered interrelationships are stored in a contextualized process plant knowledge repository, such as a graph database, that is accessible to the external systems and other systems and applications via one or more access mechanisms, which may include utilities, services, servers, and/or applications. Some of the access mechanisms allow external applications to be installed at the edge-facing component.

  • Patent number: 11435728
    Abstract: Disclosed herein are techniques for virtualizing the I/O of control modules that are to be implemented by a process controller in the runtime environment of a process plant. A configuration application identifies references to the I/O objects utilized by the control modules. In response, the configuration application generates virtual device signal tags (DSTs) to mimic the performance of the identified I/O objects. To facilitate testing and/or verification of the control module, e.g., during the commissioning of a back-end environment, the configuration application instantiates a virtual controller in a simulation environment. To generate the virtual controller, the configuration application replaces any references to the I/O objects with references to respective, generated virtual DSTs. Thus, by using the virtual DSTs as a proxy for the I/O to the field devices, the control module and/or controller may be tested prior to the field devices without the field environment being fully commissioned.

  • Patent number: 11424865
    Abstract: The described methods and systems enable process control devices to transmit and receive device variable values in a manner that enables the receiving device to verify the integrity of the received values on a variable-by-variable basis. To facilitate verification of integrity, any desired number of variables in a message may have a data integrity check in the message. For each received value that has a data integrity check, the receiving device can calculate its own data integrity check based on the received value and a seed (known to both the transmitting and receiving devices), which it can then compare to the received data integrity check to verify if the received value has been altered during communication.
