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 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.

Methods, apparatus, and articles of manufacture for modifying process control data involve obtaining the process control data in an extensible markup language format, converting the process control data in the extensible markup language format to a second data format, and storing the process control data in a database. The process control data is subsequently edited by retrieving the process control data from the database, modifying the process control data, storing the modified process control data in the second data format in the database, converting the modified process control data from the second data format to the extensible markup language format, and storing the modified process control data in the extensible markup language format.

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.

A version control system helps to keep track of versions of process plant items that may represent, or be capable of representing, entities in a process plant. The process plant items may comprise, for example, module objects which may be capable of specifically representing process entities of the process plant. These module objects may be created from module class objects which may be capable of generically representing process entities of the process plant. Version data is stored and associated with a module object. The version data may comprise data indicative of a version of a module class object that was used to create the module object. The version data may also comprise data indicative of a version of the module object. Configuration systems, version control systems, viewing systems, debugging systems, run-time monitoring systems, asset management systems, etc., may examine or permit viewing of the version control data associated with an item.

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.

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.

An appendable system includes a plurality of appendable devices that are adapted to interoperate with each other and/or a workstation via a communication network to monitor and/or control a process. Each of the appendable devices can communicate with one or more sensors and/or control outputs and includes a housing that facilitates mounting of the appendable device to a surface.

An interactive software-based network design tool that may be used to simulate and view the operation of a wireless mesh device network used in a process plant, such as a wireless HART device network, allows a user to create a model of a wireless network, input several design requirements, and automatically generate and view communication routes and schedules for the wireless network. The network design tool provides an interactive graphic interface for the addition, removal, and positioning of nodes and devices within the wireless network and a menu including several interactive screens for specifying threshold values, network topology selections, routing preferences, and other configuration parameters related to generating and optimizing communication routes and schedules within the wireless mesh network. The network design tool automatically applies a set of optimization rules along with the parameters input by user to the network model in order to generate efficient network configuration data.
