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. In particular, a single graphic display editor may be used to create interrelated graphic displays that may be accessed from one another in the runtime environment to provide further information about a process entity within one of the graphic displays, to scroll through adjacent sections of a process plant or to provide different displays for different functions within the process plant, such as for an operator viewing function, a simulation function and a maintenance function. Because the same graphic editor is used to create the graphic displays, the resultant graphic displays may have the same look and feel and may be bound to the runtime environment within the plant in generally the same manner.

Smart graphic elements are provided for use as portions or components of one or more graphic displays, which may be executed in a process plant to display information to users about the process plant environment, such as the current state of devices within the process plant. Each of the graphic elements is an executable object that includes 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 entity on a user interface when the graphic element is executed as part of the graphic display. Any of the graphic element visualizations may be used in any particular graphic display and the same graphic display may use different ones of the visualizations at different times. The different visualizations associated with a graphic element make the graphic element more versatile, at they allow the same graphic element to be used in different displays using different graphical styles or norms. These visualizations also enable the same graphic element to be used in displays designed for different types of display devices, such as display devices having large display screens, standard computer screens and very small display screens, such as PDA and telephone display screens.

Methods and systems for integrating external and/or enterprise data into a process control system are disclosed. A user interface may be provided to enable browsing and selection of a data item from an external and/or enterprise data source. The selected data item may be associated with a process control entity. At run time, independent of a configuration of the process control entity, an external data integration server or instance of an external data integration service at a process control computing device may periodically communicate with the data source to obtain an updated current value and updated current status for the selected data item for use by the process control entity. The external data integration server and/or external data integration service may consolidate access of external/enterprise data across process control entities, optimize communications with various data sources, and maintain a status of communication with each various data source.

Graphic elements and graphic 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. The graphic elements and displays include one or more objects, each of which includes a visualization, which depicts an entity within the process environment, a property associated with the depicted process entity and a routine that operates in conjunction with the visualization and the property to cause a change in the-visualization based on a change in the property, or to cause a change in the process environment based on user input through the visualization. In this manner, the graphic objects can be used to create displays that graphically illustrate, through animations and other visual operations, the changing state of the process or detected events within the process. These same graphic elements may be used to enable users to interact with a visualization on a user interface screen, such as through a mouse or a keyboard device, to cause a change in the object property, which may then provide an input to a device within the process plant.
摘要:
A configuration system uses process plant items that may represent, or be capable of representing, entities in a process plant to assist in configuring, organizing, and changing the control and display activities within the process plant. Access to the items may be controlled by associating access control data with the items. The configuration system may also use objects that represent, or may be capable of representing, one or more steps to be performed by entities in the process plant. Access to these objects may be controlled by associating access control data with the objects. The access control data may indicate whether users or certain users may be able to, for example, view or modify all or some data associated with the process plant items or the objects. The process plant items may comprise, for example, module class objects which may be capable of generically representing process entities of the process plant, module objects which may be capable of specifically representing process entities of the process plant, composite templates, module templates, etc. The objects that represent, or may be capable of representing, one or more steps to be performed by entities in the process plant may comprise, for example, phase classes or unit phases.
摘要:
Disclosed are systems and methods for on-line monitoring of operation of a process in connection with process measurements indicative of the operation of the process. In some cases, the operation of the process is simulated to generate model data indicative of a simulated representation of the operation of the process and based on the process measurements. A multivariate statistical analysis of the operation of the process is implemented based on the model data and the process measurements. The output data from the multivariate statistical analysis may then be evaluated during the operation of the process to enable the on-line monitoring of the process involving, for instance, fault detection via classification analysis of the output data.
摘要:
Graphic elements and graphic 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. The graphic elements and displays may be associated with various logical and physical elements within the process plant during configuration of the process plant, and may be configured and downloaded to the hardware within the process plant along with other configuration items, such as control routines. In particular, the graphic elements and graphic displays may be created and stored in a library, and may then be configured by being associated with various logical or physical entities within the plant. During the configuration process, the graphic elements and graphic displays may be associated with areas, equipment, process modules, control routines or control strategies of the plant as defined elsewhere in the plant configuration, or may be associated with interfaces or display devices, to define the hardware on which the graphic displays will execute during runtime, as well at to define the process entities to which these displays will be bound for display purposes. Still further, each of the graphic displays may be defined with a role or a functional use, such as an operator view, a maintenance view, etc., and these roles may be used to define the proper access and use of the graphic displays within the runtime environment.
摘要:
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.
