Highly versatile process control system controller
TLDR
A versatile controller as mentioned in this paper is a controller that can be used as either a stand-alone controller in a relatively small process plant or as one of numerous controllers in a distributed process control system depending on the needs of the process plant.Abstract:
A versatile controller that can be used as either a stand-alone controller in a relatively small process plant or as one of numerous controllers in a distributed process control system depending on the needs of the process plant includes a processor adapted to be programmed to execute one or more programming routines and a memory, such as a non-volatile memory, coupled to the processor and adapted to store the one or more programming routines to be executed on the processor. The versatile controller also includes a plurality of field device input/output ports communicatively connected to the processor, a configuration communication port connected to the processor and to the memory to enable the controller to be configured with the programming routines and a second communication port which enables a user interface to be intermittently connected to the controller to view information stored within the controller memory. When used in a distributed process control system, the controller platform may be used as a remote input/output device and the ports of this remote input/output device may be logically mapped to controllers within the distributed process control system in a manner that is different than the physical connection between such controllers and the remote input/output device.read more

Graphic element with multiple visualizations in a process environment
TL;DR: Smart graphic elements as discussed by the authors are executable objects that include a property or a variable that may be bound to an associated process entity, like a field device, and that includes multiple visualizations, each of which may be used to graphically depict the associated process entities on a user interface when the graphic element is executed as part of the graphic display.
Patent
Process plant monitoring based on multivariate statistical analysis and on-line process simulation
TL;DR: In this article, a multivariate statistical analysis of the operation of a process is implemented based on the model data and the process measurements, and the output data from the multivariate analysis may then be evaluated during the operation to enable the on-line monitoring of the process to enable fault detection via classification analysis of output data.

Associated graphic displays in a process environment
TL;DR: Graphical display support is provided within a process plant configuration, monitoring and simulation system to enable graphical displays to be created in a manner in which they are associated with one another in the runtime environment.
Patent
Graphics integration into a process configuration and control environment
TL;DR: Graphic elements and displays are provided for use in a process environment to display information to one or more users about the process environment, such as the current state of devices within a process plant as mentioned in this paper.
Patent
Methods and apparatus for modifying process control data
TL;DR: In this article, the process control data is modified by retrieving the data from the database, modifying the data, storing the modified data in the second data format in the database and converting the modified process control from the second format to the extensible markup language format.

Diagnostics in a process control system
TL;DR: In this article, a diagnostic tool automatically collects and stores data indicative of variability parameters, a mode parameter, a status parameter and a limit parameter associated with each of the different devices, loops or function blocks within a process control system.
Patent
System for configuring a process control environment
TL;DR: In this paper, a control studio object system is described, which allows a process control environment to be easily and quickly configured or modified by using a stencil portion having stencil items conforming to algorithms and a diagram portion to which the stencil item may be copied via a drag and drop operation.
