  • Patent number: 10223327
    Abstract: A device supporting big data in a process plant includes an interface to a communications network, a cache configured to store data observed by the device, and a multi-processing element processor to cause the data to be cached and transmitted (e.g., streamed) for historization at a unitary, logical centralized data storage area. The data storage area stores multiple types of process control or plant data using a common format. The device time-stamps the cached data, and, in some cases, all data that is generated or created by or received at the device may be cached and/or streamed. The device may be a field device, a controller, an input/output device, a network management device, a user interface device, or a historian device, and the device may be a node of a network supporting big data in the process plant. Multiple devices in the network may support layered or leveled caching of data.

  • Patent number: 7392165
    Abstract: A simulation system attaches to a configuration database for one or more fully configured nodes of a process control system and copies the modules within those nodes into one or more simulation computers as simulation modules. The simulation system includes an algorithm that automatically creates a reference parameter module for each of the copied nodes that stores a reference parameter for each of the inputs, outputs or other references to signals external to the nodes. In the case of the Fieldbus function blocks, the simulation system automatically creates a function block within the simulation workstation in the protocol of the controller node which mimics the operation of the Fieldbus function block, and then creates the simulation system having those mimicked Fieldbus function blocks operating as if they had originally been configured to be in the controller being simulated, instead of within a field device external to the controller.

  • Publication number: 20080082180
    Abstract: A method and device or monitoring parameters in a process reduces power consumption and bandwidth requirements in the transmission of the monitored parameter to for example, a monitoring application. In particular, new monitoring parameter values are only transmitted if the difference between a measured or calculated parameter value and the most recently transmitted value exceeds a limit, since the last communication of the parameter or if the time since the last communication of the parameter exceeds a preset refresh period. The determination as to whether to transmit the parameter can be applied to engineering unit values or raw values.

  • Patent number: 7337022
    Abstract: An optimization technique for use in driving a process plant controller, such as a model predictive controller, uses an organized, systematic but computationally simple method of relaxing or redefining manipulated, control and/or auxiliary variable constraints when there is no feasible optimal solution within pre-established constraints, to thereby develop an achievable solution for use by the controller. The optimization routine uses penalized slack variables and/or redefines the constraint model in conjunction with the use of penalty variables to develop a new objective function, and then uses the new objective function to determine a control solution that bests meets the original constraint limits.

  • Publication number: 20070208549
    Abstract: A simulation system that includes interconnected simulation blocks which use process models to perform simulation activities for a process plant is integrated into a process control environment for the process plant in a manner that makes the simulation system easy to use and easily updated for on-line process simulation. The disclosed simulation system enables future predicted values as well as the current predicted values of process parameters produced by the simulation system to be made available for performance evaluation as well as to guide plant operations. Additionally, the simulation system is connected to the operating process plant to receive various on-line process plant measurements, and uses these measurements to automatically update the process models used in the simulation system, to thereby keep the simulation system coordinated with the actual operating conditions of the process plant.

  • Publication number: 20070174225
    Abstract: A process control system element for use in a process plant includes a process module, which represents a logical unit in the process plant, integrated with an expert module capable of detecting and/or mitigating abnormal situations associated with the logical unit. The process module may include a plurality of process objects, each process object representing a corresponding physical entity in the process plant. At least some of the process objects may include simulation capabilities to simulate the corresponding physical entities. The expert module may be adapted to detect at least one abnormal situation associated with the logical unit, and may be communicatively coupled to the process module to receive data from the process module during operation of the process module. Because the expert module is integrated with the process module, a user can more easily configure the expert module to detect and/or mitigate abnormal situations associated with the logical unit.
