SYSTEMS AND METHODS FOR DISPLAYING DATA ASSOCIATED WITH THE OPERATION OF FOUNDATION FIELDBUS DEVICES

FIELD OF THE INVENTION

Embodiments of the invention relate generally to Foundation Fieldbus devices and more specifically to displaying or presenting data associated with the operation of Foundation Fieldbus devices.

BACKGROUND OF THE INVENTION

Control systems are utilized in a wide variety of different applications. For example, control systems are utilized in conjunction with power generating devices, in power plants, and/or in process plants. A control system typically includes a central controller in communication with other components of the control system, for example, sensors, measurement devices, valves, etc. The central controller typically communicates with the other components via suitable network communications.

With the development and adoption of the Foundation Fieldbus standard, Foundation Fieldbus devices have been incorporated into control systems. The use of visualization controls offered by Foundation Fieldbus Device Description (“DD”) Services allows various Fieldbus device parameters to be updated and illustrated in the control system. However, existing systems do not provide for separation of the visualization controls from other components of a suite of Foundation Fieldbus software. In conventional systems, a Foundation Fieldbus software suite is deployed as a single tier installation. In other words, a complete suite of software needs to be installed in order to utilize any of the submodules, such as a visualization module. As a result of this relatively heavy deployment, additional system resources and licensing fees are typically required in order to provide visualization and other functionality to a plurality of computing devices. Accordingly, there is an opportunity for improved systems and methods that facilitate the display of data associated with the operation of Foundation Fieldbus devices.

Indeed, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to like elements throughout.

Disclosed are systems and methods for displaying data associated with the operation of Foundation Fieldbus devices. In certain embodiments of the invention, a host device and one or more client devices may be provided. The host device may be configured to collect device parameter data associated with one or more Foundation Fieldbus devices. Additionally, the host device may be configured to execute a wide variety of software associated with Foundation Fieldbus devices. For example, the host device may be configured to execute a suite of Foundation Fieldbus software, such as a device description service kit or service pack of software. Each client device may be configured to execute a standalone version of a visualization component that is included in the suite of software executed by the host device. In this regard, data, such as device parameter data, may be communicated from the host device to a client device and displayed by the client device. Additionally, each client device is not required to execute the entire suite of available Foundation Fieldbus software. In this regard, the cost, overhead, and maintenance of multiple deployments of visualization software may be reduced.

In one example embodiment, a host system may be configured to receive live device parameter data associated with the operation of one or more Foundation Fieldbus devices. In certain embodiments, the device parameter data may include data that is output by at least one Foundation Fieldbus device, such as a Fieldbus linking device or another Fieldbus device. Additionally, as desired, the received device parameter data may include live data that is collected in real time or near real time.

Once device parameter data has been received or collected by the host device, at least a portion of the device parameter data may be communicated to one or more client devices.

In yet other embodiments, a request for device parameter data may be received by the host device from a client device, and device parameter data may be communicated to the client device in response to the request.

A wide variety of suitable techniques and/or methods may be utilized to facilitate communication of device parameter data to a client device. For example, a suitable communication channel may be established between the client device and the host device, and device parameter data may be communicated via the established communication channel. In certain embodiments, the communication channel may be a .NET Remoting communication channel, although other interprocess communication techniques may be utilized. Additionally, a wide variety of suitable networks and/or connections may be utilized to facilitate communication between the host device and a client device.

Once device parameter data has been received by a client device, the visualization component of the client device may generate one or more visual representations of the operation of the one or more Fieldbus devices. For example, a visual representation of measurements, readings, and/or other data associated with the Fieldbus devices may be generated. As desired, the visual representation may be formed as a user interface, and the visual representation may include suitable user controls. In certain embodiments, a standalone visualization module associated with Fieldbus Device Description (“DD”) Services and/or Device Definition Services, such as a suitable DDVisualization module, may be utilized to generate visual representations. As desired, suitable DDVisualization controls, such as chart, variable control representation, grid, and/or graph controls, may be utilized to generate and/or prepare the visual representations. According to an aspect of the invention, the visual representation may illustrate or depict received device parameter data and/or other live data associated with the operation of the Fieldbus devices.

Various embodiments of the invention may include one or more special purpose computers, systems, and/or particular machines that facilitate the display or presentation of device parameter data associated with the operation of Foundation Fieldbus devices. A special purpose computer or particular machine may include a wide variety of different software modules as desired in various embodiments. As explained in greater detail below, in certain embodiments, these various software components may be utilized to communicate device parameter data associated with Foundation Fieldbus devices from a host device to one or more client devices in order to facilitate the generation of visual representation of the device parameter data by the client devices.

Certain embodiments of the invention described herein may have the technical effect of facilitating the presentation of device parameter data associated with Foundation Fieldbus devices on one or more client computers in communication with a host computer. In other words, embodiments of the invention may have the technical effect of providing distributed standalone Fieldbus visualization functionality on one or more client devices. In this regard, the cost, maintenance, and overhead associated with installing Fieldbus software onto a plurality of devices may be reduced.

Various embodiments of the invention incorporate Foundation Fieldbus-type (hereinafter “Fieldbus”) devices into control systems (or other systems), for example, control systems associated with power generating devices (e.g., gas turbines, steam turbines, wind turbines, etc.), power plants, and/or process plants. A wide variety of Fieldbus devices may be utilized as desired in various embodiments of the invention. Examples of Fieldbus devices include, but are not limited to, sensors, gauges, measurement devices, valves, actuators, input/output subsystems, host systems, linking devices, any suitable Fieldbus H1 devices, and/or any suitable Fieldbus high-speed Ethernet (“HSE”) devices. In certain embodiments, H1 devices may operate and/or communicate at a different rate than HSE devices. As one example, H1 devices may operate at approximately 31.25 kilobits per second, and HSE devices may operate at approximately 100 megabits per second. As desired, various HSE devices, such as linking devices, may be utilized to interconnect H1 devices to a central controller of the control system. Additionally, the term HSE protocol may be utilized to refer to a Fieldbus protocol that facilitates communications with HSE Fieldbus devices.

Communications between Fieldbus devices and/or between one or more controllers and/or host devices of the control system and the Fieldbus devices may be facilitated by utilizing a Fieldbus protocol. The Fieldbus protocol is an all-digital serial, two-way communication protocol that provides a standardized physical interface to a bus or network interconnecting field equipment or Fieldbus devices. The Fieldbus protocol is an open-architecture protocol developed and administered by the Fieldbus Foundation. The Fieldbus protocol provides, in effect, a local area network for field instruments or field devices within a plant or facility, which enables these field devices to perform control functions at locations distributed throughout the facility and to communicate with one another before and after the performance of these control functions to implement an overall control strategy. Because the Fieldbus protocol enables control functions to be distributed throughout a process control network, it may reduce the workload of a central controller.

FIG. 1 is a block diagram of one example control system 100 that may be utilized in accordance with various embodiments of the invention. The control system 100 may include, for example, one or more host devices 105, one or more client devices 110, one or more linking devices 115a-n, and/or one or more Fieldbus devices 120a-n.

FIG. 2 is a flow diagram of one example method 200 for displaying or presenting device parameter data associated with Foundation Fieldbus devices, according to an illustrative embodiment of the invention. The method 200 may be performed by a suitable host device and client device, such as the host device 105 and client device 110 associated with the control system 100 of FIG. 1. In certain embodiments, various operations of the method 200 may be performed by a suitable DD Services and/or host module functionality of the host device 105 and by suitable standalone visualization functionality associated with the client device 110. The method may begin at block 205.

At block 205, a suitable client device description application or module may be executed by a client device 110. According to an aspect of the invention, the executed application may be a suitable application that facilitates the visualization and/or display of data associated with Foundation Fieldbus devices. For example, the application may be a suitable application that facilitates the display of device parameter data associated with Foundation Fieldbus devices. Additionally, in certain embodiments of the invention, the application or module may be a standalone application or module. In other words, the application may be separated from and/or distributed from a suite of Foundation Fieldbus software that provides additional functionality. In this regard, the implementation and maintenance cost associated with installing and executing the application on the client device 110 may be relatively lower than the cost associated with installing an entire suite of Foundation Fieldbus software.

At block 210, the client device 110 and/or the application executed by the client device 110 may request the establishment of a remote communication channel or communication session with a host device 105. A wide variety of different types of requests may be utilized as desired to facilitate the establishment of a remote communication channel or session. For example, a request to establish a .NET Remoting session may be communicated to the host device 105. The host device 105 may be a suitable device that is configured to receive or collect device parameter data that is output by one or more Foundation Fieldbus devices. Additionally, the host device 105 may be configured to execute a wide variety of different Foundation Fieldbus software, such as a DD Services kit or other suite of Foundation Fieldbus software. This software may provide a wide variety of different identification, control, visualization, and/or other functions associated with the Fieldbus devices.

At block 215, the request to establish a remote communication channel or session may be received by the host device 105. The host device 105 may then establish a suitable communication channel or communication session with the client device 110 at block 220. For example, a .NET Remoting communication channel may be established between a host module of the host device 105 and the device description application executed by the client device 110.

At block 225, a wide variety of identification information and/or configuration information associated with the Foundation Fieldbus devices may be communicated to the client device 110 by the host device 105.

As another example, device description data associated with the Foundation Fieldbus devices may be communicated. The communicated identification and/or configuration information may be received by the client device 110 at block 230. As desired, at least a portion of the information may be displayed to a user of the client device 110. In this regard, a user may specify Fieldbus devices and/or various data parameters for which device parameter data is desired. For example, a user selection of desired device parameter data may be received by the client device 110 at block 235. As desired, a user may utilize a wide variety of menus, options, and/or other selectable indicators in order to provide a user selection of desired device parameter data to the client device 110.

At block 240, a request for device parameter data may be generated by the client device 110 and communicated to the host device 105. For example, information associated with a user selection may be evaluated and utilized to request desired device parameter data. As another example, the client device 110 may utilize a user profile to request desired device parameter data. As yet another example, the client device 110 may request available device parameter data.

The request for device parameter data may be received by the host device 105 at block 245. At block 250, the host device 105 may identify and/or collect the requested device parameter data. The requested device parameter data may then be returned to the client device 110. For example, the device parameter data may be communicated to the client device 110 in response to a .NET Remoting request and/or via an established communication channel. In certain embodiments, requested device parameter data may be continually communicated to the client device 110 in real time or near real time. In other embodiments, identified changes in the device parameter data may be communicated by the host device 105 to the client device 110. In this regard, relatively up-to-date data may be received by the client device 110.

At block 255, device parameter data may be received by the client device 110 from the host device 105. In certain embodiments of the invention, device parameter data may be continuously received in a real time or near real time manner. At least a portion of the received device parameter data may be processed by the client device description application at block 260 in order to generate one or more visual representations associated with the operation of the Fieldbus devices. For example, one or more charts, graphs, grids, and/or other visual representations may be generated by the device description application. The generated one or more visual representations may then be output for display or presentation to a user of the client device 110 at block 265.
