The subject application relates generally to industrial automation, and, more particularly, to provision of industrial automation applications using a cloud-based provisioning system.
Early industrial automation systems were purely hardware-based, comprising complicated networks of relays, switches, timers, logic gates, and other such elements. With the advent of the programmable logic controller (PLC), many of these cumbersome hardware elements were replaced by equivalent software solutions, significantly reducing the size and complexity of automation systems. Over time, more aspects of the industrial automation process have come to rely on software-based solutions, including visualization (e.g., human-machine interfaces), control loop tuning, motor drive configuration, lot tracking, historical data collection, production reporting, etc. Moreover, recently developed software products have made it possible to integrate plant floor operations with higher level business considerations, allowing both levels to more easily coordinate their activities to achieve desired goals of the business enterprise as a whole. Such software products include enterprise resource planning (ERP) software, manufacturing execution system (MES) software, and other such applications.
As new industrial software products are introduced into the market place, there is an increasing reliance on such industrial software applications for the day-to-day operation of modern industrial automation systems and associated business planning.
The following presents a simplified summary in order to provide a basic understanding of some aspects described herein. This summary is not an extensive overview nor is intended to identify key/critical elements or to delineate the scope of the various aspects described herein. Its sole purpose is to present some concepts in a simplified form as a prelude to the more detailed description that is presented later.
One or more embodiments of the present disclosure relate to cloud-based provisioning of industrial automation applications. To this end, an industrial application provisioning system can be made available to developers and end users on a cloud platform. Industrial application developers can submit pre-tested industrial applications to an application library associated with the cloud-based application provisioning system. A client interface for the provisioning system can allow the developer to associate metadata with the application that can be used by the provisioning system to categorize the application in the library for simplified searching and browsing. In some embodiments, this metadata can specify a particular industry, control system type, device, equipment type, or vendor to which the submitted application relates.
The cloud-based provisioning system can include a search engine that allows an end user or another developer having access to the cloud platform to quickly and easily search for a desired industrial automation application as well as related components, modules, and/or extension packs for such applications. By virtue of the category metadata associated with the respective applications and their associated components, the user can search the cloud-based library for relevant industrial automation applications based on such criteria as the industry type, equipment in use, automation application (e.g., motor control, batch processing, welding, etc.), or other such criteria. Authorized users can also apply a ranking to selected applications in the library indicating a perceived quality of the selected applications for the consideration of other potential users of the applications.
In another aspect, the industrial application provisioning system can search for or filter applications in the cloud-based library based on contextual data obtained from the client. For example, a local search client associated with the provisioning system can determine one or more data structures, devices, or equipment in use at a customer's facility, and leverage this data to select a subset of industrial applications determined to be of potential relevance to the customer's automation system.
In one or more embodiments, the cloud-based provisioning system can download selected applications to an end user's local cloud-capable device. Alternatively, the cloud-based provisioning system can allow users to execute selected applications on virtual machines residing on the cloud platform using the cloud's storage and processing resources, thereby preserving the customer's local resources. These cloud resources can be allocated to an industrial enterprise for this purpose as a client-specific cloud resource allocation.
To the accomplishment of the foregoing and related ends, certain illustrative aspects are described herein in connection with the following description and the annexed drawings. These aspects are indicative of various ways which can be practiced, all of which are intended to be covered herein. Other advantages and novel features may become apparent from the following detailed description when considered in conjunction with the drawings.
The subject disclosure is now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding thereof. It may be evident, however, that the subject disclosure can be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate a description thereof.
As used in this application, the terms “component,” “system,” “platform,” “layer,” “controller,” “terminal,” “station,” “node,” “interface” are intended to refer to a computer-related entity or an entity related to, or that is part of, an operational apparatus with one or more specific functionalities, wherein such entities can be either hardware, a combination of hardware and software, software, or software in execution. For example, a component can be, but is not limited to being, a process running on a processor, a processor, a hard disk drive, multiple storage drives (of optical or magnetic storage medium) including affixed (e.g., screwed or bolted) or removably affixed solid-state storage drives; an object; an executable; a thread of execution; a computer-executable program, and/or a computer. By way of illustration, both an application running on a server and the server can be a component. One or more components can reside within a process and/or thread of execution, and a component can be localized on one computer and/or distributed between two or more computers. Also, components as described herein can execute from various computer readable storage media having various data structures stored thereon. The components may communicate via local and/or remote processes such as in accordance with a signal having one or more data packets (e.g., data from one component interacting with another component in a local system, distributed system, and/or across a network such as the Internet with other systems via the signal). As another example, a component can be an apparatus with specific functionality provided by mechanical parts operated by electric or electronic circuitry which is operated by a software or a firmware application executed by a processor, wherein the processor can be internal or external to the apparatus and executes at least a part of the software or firmware application. As yet another example, a component can be an apparatus that provides specific functionality through electronic components without mechanical parts, the electronic components can include a processor therein to execute software or firmware that provides at least in part the functionality of the electronic components. As further yet another example, interface(s) can include input/output (I/O) components as well as associated processor, application, or Application Programming Interface (API) components. While the foregoing examples are directed to aspects of a component, the exemplified aspects or features also apply to a system, platform, interface, layer, controller, terminal, and the like.
As used herein, the terms “to infer” and “inference” refer generally to the process of reasoning about or inferring states of the system, environment, and/or user from a set of observations as captured via events and/or data. Inference can be employed to identify a specific context or action, or can generate a probability distribution over states, for example. The inference can be probabilistic—that is, the computation of a probability distribution over states of interest based on a consideration of data and events. Inference can also refer to techniques employed for composing higher-level events from a set of events and/or data. Such inference results in the construction of new events or actions from a set of observed events and/or stored event data, whether or not the events are correlated in close temporal proximity, and whether the events and data come from one or several event and data sources.
In addition, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or.” That is, unless specified otherwise, or clear from the context, the phrase “X employs A or B” is intended to mean any of the natural inclusive permutations. That is, the phrase “X employs A or B” is satisfied by any of the following instances: X employs A; X employs B; or X employs both A and B. In addition, the articles “a” and “an” as used in this application and the appended claims should generally be construed to mean “one or more” unless specified otherwise or clear from the context to be directed to a singular form.
Furthermore, the term “set” as employed herein excludes the empty set; e.g., the set with no elements therein. Thus, a “set” in the subject disclosure includes one or more elements or entities. As an illustration, a set of controllers includes one or more controllers; a set of data resources includes one or more data resources; etc. Likewise, the term “group” as utilized herein refers to a collection of one or more entities; e.g., a group of nodes refers to one or more nodes.
Various aspects or features will be presented in terms of systems that may include a number of devices, components, modules, and the like. It is to be understood and appreciated that the various systems may include additional devices, components, modules, etc. and/or may not include all of the devices, components, modules etc. discussed in connection with the figures. A combination of these approaches also can be used.
The industrial application provisioning system 104 is accessible by application developers and application users to facilitate publication and sharing of industrial automation applications via the cloud platform 102. In general, industrial software applications can be developed and submitted to the industrial application provisioning system 104 by a development workstation 112 having cloud access capability. In an exemplary configuration, development workstation 112 may access the industrial application provisioning system 104 through a separate cloud interface 110, where the development workstation 112 connects to the cloud interface 110 through a physical or wireless local area network or radio link. In another exemplary configuration, cloud interface 110 may be integrated with the development workstation 112, which accesses the cloud platform 102 directly using the integrated cloud interface.
Client device 116 (typically associated with an industrial facility or enterprise) can access one or more libraries of published industrial automation applications maintained by the industrial application provisioning system 104. Similar to the development workstation 112, client device can access the industrial application provisioning system 104 and associated cloud-based services via a cloud interface 114, which can be internal to the client device 116 or a separate cloud gateway communicatively connected to the client device 116. Client device 116 may be any suitable device capable of submitting search criteria to the industrial application provisioning system 104 and receiving one or more industrial applications from the provisioning system, including but not limited to a desktop computer, a laptop, or a cloud-capable mobile device such as a mobile phone or tablet computer.
Client device 116 can also be a cloud-capable industrial device, such as an industrial controller (e.g., programmable logic controllers or other types of programmable automation controllers); a field device such as sensor or a meter; a motor drive; a human-machine interface (HMIs) station; an industrial robot; a barcode marker or reader; a vision system device (e.g., vision camera); a smart welder; or other such industrial devices. Allowing industrial devices to access the industrial application provisioning system 104, either directly or through a protected cloud interface or gateway, can offer a number of advantages, such as allowing industrial devices to automatically retrieve updates to their native industrial software applications when such updates are published to the cloud platform 102. Industrial client devices 116 may include smart configuration capability, enabling the industrial devices to automatically detect and communicate with the cloud platform 102 upon installation at a facility, simplifying integration with existing cloud-based provisioning, data storage, analysis, or reporting services provided by the cloud platform 102.
Industrial application provisioning system 202 can include a publish component 204, a search component 206, a retrieval component 208, an interface component 210, a subscription component 212, a notification component 214, one or more processors 216, and memory 218. In various embodiments, one or more of the publish component 204, search component 206, retrieval component 208, interface component 210, subscription component 212, notification component 214, one or more processors 216, and memory 218 can be electrically and/or communicatively coupled to one another to perform one or more of the functions of the industrial application provisioning system 202. In some embodiments, components 204, 206, 208, 210, 212, and 214 can comprise software instructions stored on memory 218 and executed by processor(s) 216. The industrial application provisioning system 202 may also interact with other hardware and/or software components not depicted in
Publish component 204 can be configured to receive submission of an industrial automation application from a remote client device (e.g., a development workstation 220 having a cloud interface 224) via a cloud platform and publish the industrial automation application to one or more application libraries 228. As illustrated in
Search component 206 can be configured to receive search criteria from a remote client device (e.g., client device 222, via cloud interface 226) via the cloud platform and identify a subset of the industrial applications in the library 228 matching the received criteria. Retrieval component 208 can retrieve the subset of industrial applications identified by the search component 206 and deliver the identified applications to the originator of the search request. This can include sending the industrial applications to the requesting client device 222 over the cloud platform, or sending only a set of indicators identifying the subset of industrial applications.
Interface component 210 can be configured to establish communication and exchange data with remote devices. Accordingly, interface component 210 can authenticate a client device or user wishing to access the provisioning system 202, receive industrial application submissions, receive search criteria, and send retrieved industrial applications and other user feedback to the remote devices.
One or more embodiments of the industrial application provisioning system 202 can allow users to subscribe to receive notifications or application updates relating to selected industrial applications or application categories. Accordingly, subscription component 212 can be configured to receive and manage subscription requests from remote clients, and notification component 214 can be configured to deliver notifications to the remote clients when new or updated industrial applications corresponding to the subscription requests become available. For example, subscription component 212 can store association information (e.g., in memory 218) that associates a set of subscription criteria with one or more devices or users. The subscription component can then determine when a new industrial application or an update to an existing industrial application matching the subscription criteria is published to the application library 228, and instruct notification component 214 to deliver notifications to the subscribing client devices.
The one or more processors 216 can perform one or more of the functions described herein with reference to the systems and/or methods disclosed. Memory 218 can be a computer-readable storage medium (or multiple storage media) storing computer-executable instructions and/or information for performing the functions described herein with reference to the systems and/or methods disclosed.
Exemplary industrial applications and related components suitable for storage in the application libraries 310 can include, but are not limited to, industrial control programs or modular code segments for performing specific industrial control tasks (e.g., applications that can generate and deliver control instructions to industrial devices based on analysis of near real-time system data or other factors), visualization applications, externally defined graphical elements (EDGE definitions) that can be imported into a visualization application during interface screen development, plant reporting applications, Enterprise Resource Planning (ERP) applications, manufacturing execution system (MES) software, firmware for industrial devices, software add-ons for implementing electronic signatures, or other such applications. In one or more embodiments, the system can facilitate publication and retrieval of validated application code, which is code that has been validated pursuant to one or more defined industry standards (e.g., FDA validated code for pharmaceutical applications). The application libraries 310 can also store certified code (e.g., for safety-related industrial applications) and secure application code that has been digitally signed to ensure authenticity.
Configuration files or configuration data for industrial devices may also be published to application libraries 310 for distribution to end users. For example, in order to simplify configuration of a variable frequency drive for a desired mode of operation or for use in a particular type of automation application, a configuration file containing parameter values for the drive can be published to application libraries 310. The parameter values represent device settings that configure the drive for the desired mode of operation. Thus, an engineer or maintenance personnel can search for and retrieve the configuration file from the application libraries 310 and apply the configuration file to the drive, mitigating the need to determine suitable parameter values through trial-and-error during testing.
The application libraries 310 may also include industrial software widgets or dashboards developed by original equipment manufacturers (OEMs) that facilitate monitor and/or control of their proprietary equipment. In addition to the industrial applications and related components, the application library 310 can include associated help files, usage tips, frequently-asked-questions (FAQs), instructional videos, or other such materials to guide users in connection with using the respective applications.
The industrial automation provisioning system 302 can also be used to facilitate code sharing between software developers over the cloud platform. For example, software developers working in geographically remote locations on a common software project may publish software fixes or new code blocks to the provisioning system 302 so that co-developers can access the new or updated code during development. Thus, the industrial automation provisioning system 302 can facilitate provisioning of not only complete industrial applications, but also add-on functional modules for such applications, application upgrades or bug fixes, extension packs, etc. Publication and provisioning of such modular application components can be performed independently of the provisioning of the applications themselves.
As noted above, the industrial application provisioning system 302 can store industrial applications according to an industry-specific, hierarchical cataloging schema. That is, application developers 304 can publish their new or modified industrial applications according to pre-defined industry-specific categories and sub-categories supported by the catalog's storage structure. Industrial application provisioning system 302 can support a hierarchical arrangement of these categories and sub-categories to simplify subsequent location and retrieval of industrial automation applications or code using browsable search features. Some embodiments of the provisioning system 302 can also provide a means for application developers 304 to define their own categories for a given industrial application, thereby affording designers a degree of freedom in expanding the hierarchical storage structure of the application libraries 310 as new areas of control evolve. The provisioning system 302 also supports publishing of samples and documentation together with the published industrial applications.
Authorized application users 306 wishing to locate and retrieve an industrial application can interact with the cloud-based provisioning system 302 through a search client served by the provisioning system 302 to the user's client device. The search client can support keyword-based querying of the libraries 310 and/or a browsable interface that allows the user to navigate the library hierarchy. Both keyword querying and browsed searching permit searching for a given industrial application based on such criteria as applicable industry (e.g., automotive, pharmaceutical, waste water treatment, etc.), type of control project (e.g., motion control, batch processing, material handling, etc.), type of application required, or any other suitable pre-defined or user-defined category.
In some embodiments, the industrial application provisioning system can serve a publishing interface to the developer's device designed to facilitate submission of the industrial application to the provisioning system. Using this publishing interface, the developer can set values for the metadata tags' data fields using tagging functionality provided by the publishing interface. Some metadata tag values may also be set automatically generated during development of application.
Exemplary metadata tags 406 can include the following data fields:
Control Type: The type of industrial control to which the application 404 relates. For example, the Control Type field can indicate whether the application 404 relates to discrete control systems or process control systems.
Industry: The industry or business in which industrial application 404 is intended to be used. Exemplary values for the Industry field include “Automotive,” “Pharmaceutical,” “Wastewater Treatment,” “Oil and Gas,” “Power,” “Food and Beverage,” “Material Handling,” “Metalforming,” or other suitable industrial categories.
Category and sub-categories: Hierarchical classification tiers used to determine how the industrial application 404 is to be classified within the provisioning system's industry-based hierarchy. The categories and sub-categories can specify particular industrial devices or equipment that the industrial application 404 is intended to monitor or control, a type of industrial process in which the application 404 is applicable (e.g., batch processing, material handling, motion control, vision, die casting, etc.), a type of application (e.g., HMI graphic, widget, controller code, firmware, etc.), or other such pre-defined or user-defined sub-categories.
Developer, Creation Date, Description, Revision: Name of the individual or organization submitting the industrial application 404, date of creation, functional description, and revision number of industrial application 404.
Additional Search Terms: Search terms and keywords not included in the other metadata fields that the developer wishes to associate with the industrial application 404 to ensure the definition is identified in relevant catalog searches.
Platform Compatibility: List of software platforms (e.g., operating systems) compatible with the industrial application 404.
Hardware Compatibility: List of hardware platforms compatible with the industrial application 404. This field can include identification of one or more industrial devices on which the application is designed to execute, or which the application is intended to monitor and/or control.
User Ranking: A quality ranking for the application 404, calculated as an average or aggregate of quality rankings received from multiple users of the application 404. Such rankings can be provided to the provisioning system as user feedback from users who have downloaded and used the industrial application 404.
It is to be appreciated that the fields depicted in exemplary metadata tag 406 are not intended to be exclusive, nor does the metadata tag require all data fields depicted in
Additionally, read-write permissions for the respective fields can vary in accordance with their functions. For example, the Creation Date field can be a read-only field that is automatically set to the date when the industrial application 404 was last modified. Other fields, such as the Additional Search Terms field, can have full read-write attributes, thereby allowing a user to enter data freely. Still other data fields can be populated by selecting an entry from a drop-down menu or other list associated with the data field, where such menus are provided by the client interface served by the provisioning system. In one or more embodiments, the Control Type, Industry, Category, and/or Sub-category fields can incorporate such drop-down menus, which can be populated by the provisioning system to correspond with the Control Type, Industry, Categories, and Sub-categories comprising the storage hierarchy of the application library.
As discussed above, industrial applications submitted to the provisioning system of the present disclosure can be classified within a cloud-based application library according to a hierarchy of industry-specific categories to facilitate guiding a user to a desired industrial application.
Two exemplary Control Type classifications are depicted in
It is to be appreciated that the hierarchical format depicted in
Application development environment 604 runs on development workstation 602 and is used to develop an industrial application 616, which is to be submitted to the provisioning system 608. Application development environment 602 can comprise any suitable design tool or programming platform that provides a developer the means to create or modify an industrial application for shared use. In some scenarios, application development environment 604 will be a stand-alone development platform. However, some embodiments of the industrial application provisioning system 608 can provide a remote development environment to cloud-capable computing devices for development, testing, and debugging of industrial applications. In such embodiments, this cloud-based development environment can allow users to leverage cloud resources (e.g., storage, processing, bandwidth, etc.) to develop industrial applications for subsequent storage and publication on the provisioning system 608. To facilitate access to this cloud-based development environment, the provisioning system 608 can serve a development interface to the development workstation 602 that serves as an interface to the development environment. This can allow the development workstation 602 to access and utilize the development environment from an authorized cloud-capable device. In some embodiments, the cloud-based development environment can include integrated testing and simulation capability, allowing applications in progress to be simulated, tested and debugged using cloud resources provided by the cloud platform. Applications in development may also be stored on the cloud platform between development sessions. The use of cloud resources to develop industrial applications in this manner can also facilitate sharing of development tasks between geographically diverse application developers, since multiple developers at different locations can access the application in progress from any authorized cloud-capable computing device.
When a new or modified industrial application is ready for submission to the provisioning system 608, the developer can invoke publishing client 606. The publishing client 606 can be a remote web-based client served by the provisioning system 608, or a locally executed client on development workstation 602 that can be invoked and communicatively linked to the provisioning system 608 over the Internet. Publishing client 606 can include functionality that allows a developer to associated metadata with the industrial application that can subsequently be used by the provisioning system 608 to classify the industrial application within an industry-specific storage hierarchy, as discussed above in connection with
The industrial application submission 618 is submitted to the provisioning system 608, where a publish component 610 adds the application to the industrial application library 614. Application library 614 can be maintained on one or more data stores 612 on the cloud platform. Publish component 610 can parse the metadata tags included in the application submission 618 (e.g., metadata tags 406 of
In one or more embodiments, location and retrieval of an industrial application can be effected by submitting keyword-based search criteria 714 to the provisioning system 704 via search interface 708. Search interface 708 submits the search criteria 714 to the cloud-based provisioning system 704 across a generic Internet layer. Search criteria 714 can comprise one or more keywords entered by the user using the search interface 708. Typically, a user will submit keywords that identify one or more of an industrial domain, a control type (e.g., discrete control, process control, etc.), a type of automation application, a device or piece of equipment in use, an industry standard, or any other terms that can be used by the provisioning system to identify a desired subset of industrial applications stored in industrial application library 726. In one or more embodiments, a subset of the search criteria 714 can also be inferred by the search interface 708 based in part on extrinsic data relating to the user's existing control system, as will be discussed in more detail below.
When search criteria 714 is submitted to the provisioning system 704, an interface component 718 receives the search criteria 714 and passes the criteria to a search component 720, which identifies a subset of industrial applications stored in application library 726 (similar to application library 310 of
Moreover, one or more embodiments of search component 720 can support “approximate match” searching, such that exact matches between the submitted search criteria 714 and a potentially relevant industrial application's metadata or properties is not necessary in order for the industrial application to be selected for inclusion in the retrieved subset. In this regard, any suitable “fuzzy search” methodology can be employed to ensure that useful industrial applications are returned even in the absence of an exact match. In one exemplary approach, upon receipt of search criteria 714, search component 720 can calculate one or more figures of merit for each industrial application in the library 726 relative to the search criteria. Each application's figure of merit is a relative measure of how relevant the given definition is likely to be to the search criteria. For example, if a search criterion stipulates that a requested industrial application is to be used in an automotive HMI application, the search component 720 can generate an “industry” figure of merit for each industrial application in the library 726 indicating a relative applicability to the automotive industry. Industrial applications whose metadata explicitly specifies “automotive” as an applicable industry will be given the highest figure of merit. Applications whose industry metadata specifies a different industry but having similarities to the automotive industry (e.g., commonly employs similar equipment or processes, often produces materials or products used by the automotive industry, etc.) will be given a comparatively high (though not the highest) figure of merit with respect to industrial applications designed for a non-related industry. When all figures of merit have been identified, search component 720 can identify the subset of industrial applications having a figure of merit above a threshold value as being sufficiently relevant to the search criteria. According to one or more embodiments, multiple figures of merit can be calculated for each industrial application for a given set of search criteria, where each figure of merit relates to a particular search dimension or aspect (e.g., industry, control type, category, desired functionality, etc.). In such embodiments, a composite figure of merit can be computed based on the individual figures of merit for the various search dimensions, and the relevant subset of industrial applications can be selected by the search component 720 based on this composite value.
After the subset of relevant industrial applications from library 726 has been identified, the provisioning system 704 can render a list of the identified applications on the search interface 708 for selection by the user. Each item in the list can include a description of the application, including information derived from the application's metadata (e.g., control type, industry, function, etc.). The search interface 708 can receive input from the user indicating selection of one of the industrial applications in the list, and inform the provisioning system 704 of the user's selection. Based on the user selection, the retrieval component 722 retrieves the identified industrial application from the library 726.
In one or more embodiments, libraries 614 and 726 described above can comprise centralized, common libraries accessible to suitably authorized users across multiple locations and enterprises (e.g., via a subscription service). In some embodiments, the industrial application provisioning system can also allow users to create and maintain personal libraries on the cloud platform for storage of selected industrial applications or related software components. In such embodiments, the system allows the user to import industrial applications (or related components) into their personal cloud-based application library from other libraries (e.g., the commonly accessible library described above) or to publish their own user-developed applications and related components to the personal library. Such personal application libraries can utilize a subset of cloud resources (e.g., storage, processing, and/or bandwidth) allocated to the user or the user's business enterprise. The system can allow the user to configure these personal application libraries such that access to the applications and software components stored thereon is limited to authorized personnel within their company. In this way, the system allows the user to build custom application libraries for personal or internal use, comprising applications or associated software component of particular value or potential utility for the user or enterprise.
In some embodiments, the provisioning system 704 can provide the retrieved industrial application 716 to the client device over the Internet for local usage. That is, the selected industrial application 716 can be downloaded from the provisioning system 704 and stored on local storage 706 at the client device. Alternatively, some embodiments of the provisioning system 704 can allow certain industrial applications to be run remotely using cloud resources provisioned to the user or to the industrial facility.
As in previous examples, client devices 8061 and 8062 can search for and retrieve desired industrial applications from the application library 810 managed by provisioning system 802. However, rather than downloading the selected applications to the client devices 8061 and 8062 for local use at the respective facilities 8081 and 8082, the selected applications can instead be executed on the cloud platform using each facility's allocated cloud resources 8041 and 8042. In some cases, cloud-based execution of industrial applications may not be appropriate, as in the case of industrial applications comprising controller code designed to control plant floor machinery. However, many industrial applications could beneficially be maintained and executed remotely on the cloud platform as illustrated in
In addition to query-based searching, one or more embodiments of the industrial application provisioning system 704 can also support browsed searching of the industrial application library 726 by allowing the user to navigate the classification hierarchy until a desired industrial application is found. Returning now to
One or more embodiments of the provisioning system described herein can also support implementation of corporate filters to limit selection and retrieval of applications to a subset of pre-approved industrial applications or application types. For example, some industries may require that all software used in connection with control and operation of an industrial process conform to a defined set of standards (see, for example, the 21 CFR Part 11 standards applied to the food and drug industry). Additionally, some industrial facilities may have their own set of internally defined standards, or may wish to simplify the search and retrieval process by limiting the applications returned by the provisioning system only to those applications relevant to the facility's particular industry. To ensure that only pre-approved code is retrieved from the provisioning system, one or more embodiments of the industrial application provisioning system can allow each industrial customer to define a set of corporate filters to be applied to all application searches made by plant personnel.
As discussed above, some embodiments of the industrial application provisioning system can infer at least a portion of the application search criteria based in part on extrinsic data read from the user's existing control system. For example, certain control data structures, code segments, or HMI graphical elements may suggest that the user's existing system relates to a particular industry or type of industrial system, or may help to identify particular devices or equipment in use at the industrial facility without requiring the user to explicitly provide such information to the provisioning system.
Consider an example in which automation application 1014 is a controller program residing on automation device 1012, which can be an industrial controller (e.g. programmable logic or automation controller). The control program can include a number of control data structures 1010 that assist with data management and instruction processing within the program, such as control instructions, memory tags of various data types, I/O module configurations, etc.
According to one or more embodiments, the search criteria generation component 1004 can read one or more control data structures 1010 from the automation application 1014. Control data structures 1010 extracted by the search criteria generation component 1004 can include, but are not limited to, controller tags and their associated data types (e.g., real, integer, binary, double, string, etc.), instructions and/or function blocks used in the control program, and any metadata associated with the various program elements. Search criteria generation component 1004 can also read, as control data structures, configuration information for the I/O modules associated with the automation device 1012, which are used to exchange digital and analog signaling between the automaton application 1014 and field devices comprising the controlled system.
Upon reading the one or more control data structures from automation program 1012, search criteria generation component 1004 can make an inference regarding industrial equipment in use (e.g., devices being monitored and/or controlled by automation application 1014), an industry to which the automation application 1014 relates, a type of process being controlled by automation application 1014, or other relevant characteristics of the user's system. For example, if a particular control data structure 1010 in automation application 1014 indicates that a particular type of variable frequency drive (VFD) is being controlled by automation application 1014 as part of the broader system control, the search criteria generation component 1004 may generate search criteria 1008 designed to locate a graphical object (e.g., EDGE definition) representing the identified VFD, a widget designed to read and display operational data for the identified VFD, code segments relating to motor control applications, or other such applications determined to be relevant. In another example, the control data structures 1010 may indicate that the automation device 1012 includes an I/O module designed to control a particular type of servo motor. Accordingly, based on the presence of these control data structures in the automation application 1014, the search criteria generation component 1004 can generate search criteria 1008 including the name of the vendor of the servo motor, keywords relating to servo control or motion control in general, or other such criteria.
In some cases, the generated search criteria 1008 can be based in part on a pre-defined mapping between particular data structures (e.g., function blocks, metadata keywords, I/O modules in use, etc.) and relevant search terms. For example, the pre-defined mapping can associate a controller tag's data type with a particular set of search criteria. In another example, a control data structure identifying an I/O module in use can also be mapped to another set of search criteria. Likewise, control data structures representing instructions used within a controller program can be associated with yet another set of search criteria. In this way, some embodiments of the search criteria generation component 1004 can allow a user to pre-specify search criteria to be submitted to the provisioning system 1022 for respective types of control data structures 1010.
In some embodiments the provisioning system search interface 1002 can further allow a user to define usage-based associations between control data structures and industrial application search criteria. That is, an associative link between a control data structure and one or more sets of search criteria can be conditional on how the control data structure is used in automation application 1014 (e.g., in which subroutine or control module of the control program the control structure is located). As an example of such a mapping, a user can specify that controller tags having a REAL data type and located in a “Die Cast” subroutine are to be associated with bar graph display objects, while similar tags located in a “Sand Casting” subroutine are to be associated with line graph display objects.
Search criteria generation component 1004 can read a control data structure 1010 from automaton application 1014 and cross-reference this control data structure with the pre-defined mapping. Using this information, search criteria generation component 1004 can generate provisioning system search criteria 1008 for the control data structure based on the mapping of preferred display object types. That is, for a given control data structure read from automation application 1014, the search criteria generation component can generate search criteria for locating one or more suitable graphical elements (e.g., EDGE definitions, GUI components, etc.) that can be imported into an HMI application or added to a computer desktop as a widget for visualization of and/or operator interaction with the control data structure.
The automatically generated search criteria can be submitted alone or in combination with additional user-entered search criteria. As described in previous examples, the search criteria 1008 can be provided to search component 1016 of provisioning system 1022 (e.g. through cloud interface 1006), and retrieval component 1018 can retrieve selected industrial applications identified by the search criteria 1008 from application library 1020.
Although search criteria generation component 1004 is depicted in
One or more embodiments of the industrial application provisioning system can also allow users to subscribe to receive notifications of updates or revisions to selected industrial applications in the library. An exemplary cloud-based provisioning system having subscribe and notify capabilities is illustrated in
Provisioning system 1102 can further include a notification component 1108 that works in conjunction with subscription component 1110. Notification component 1108 monitors the industrial application library 1104, and in particular tracks revisions made to individual industrial applications stored therein. For instance, if a new industrial application is published to the library 1104 (e.g., using the techniques described above in connection with
Upon determining that the newly published industrial application is a revision of a previously published application, notification component 1108 can reference subscribers database 1106 to determine if any users are subscribed to receive notifications relating to the previously published application which served as an antecedent for the new application. If so, notification component 1108 can send a notification to the subset of clients 11121-1112N on the subscription list that a new revision of the industrial application is available for retrieval from the cloud-based library 1104. Such notifications can be transmitted by the notification component 1108 to each user's preferred contact destination as defined in the subscriptions. Notification component 1108 can transmit the notifications to the appropriate users according to each user's preferred notification method as indicated in the respective subscriptions, including, but not limited to, email, text message, voice message, notification via the catalog client, etc.
The industrial application provisioning system of this disclosure provides a means for developers to share their industry- and application-specific industrial applications with other users over a cloud platform, allowing users and application developers to easily leverage the experience and expertise of other developers. While some application developers may wish to publish their industrial applications for free distribution, it is understood that other application developers may wish to charge a license fee for the download and use of their applications. Accordingly, one or more embodiments of the industrial application provisioning system can include a licensing component that determines whether a requested application is associated with a license requirement, as illustrated in
If a license requirement is identified, a payment component 1214 can send a prompt to the client device from which the request was received, instructing the user that a payment must be submitted before the industrial application can be retrieved for use. Alternatively, the industrial application can be provided to the client device on a provisional trial basis, such that usage rights will be terminated after a defined period of time unless a license payment is received within the defined time frame. The provisioning system 1202 can provide an interface that allows the user to submit the payment electronically (e.g., by allowing the user to enter bank account routing information, credit or debit card information, electronic payment transfer information, or any other suitable payment method). Payment component 1214 can receive the electronic payment information and route the payment information to the necessary financial institutions (determined based on the financial information provided by the industrial application developer via the metadata tags). When payment has been confirmed, retrieval component 1208 can retrieve the requested industrial application and deliver the application to the client device or allow usage of the application on a set of cloud resources provisioned to the user.
At 1304, the cloud-based application provisioning system reads metadata submitted with the industrial application. This metadata can be used to categorize the application in the library for simplified searching and browsing, as described above in connection with
At 1402, a library of stored industrial applications is filtered according to the received search criteria. The stored industrial applications can be cataloged in the library according to an industry-specific classification hierarchy, as described in previous examples, and the industrial application provisioning system can filter the stored applications to identify a subset of industrial applications matching the received search criteria. At 1406, a selection of one of the filtered industrial applications is received from the client device, where the selection indicates that the identified industrial application is to be made available for use by a user of the client device or an industrial enterprise with which the user is affiliated.
At 1408, it is determined whether the selected industrial application is to be run as a virtual machine on the cloud platform, or alternatively if the selected industrial application is to be downloaded to the client device for local execution. If the selected industrial application is to be run as a virtual machine, the method moves to step 1412, where the selected industrial application is made available for execution on a set of cloud resources provisioned to the user, as described above in connection with
At 1506, industrial application search criteria is generated or refined in accordance with the inferred industry, equipment, or type of control application determined at step 1504. The search criteria can be designed to locate a subset of stored industrial applications that may be relevant to the automation system in use, based on the inferred information about the automation system determined at step 1504. At 1508, the search criteria generated at step 1506 is submitted to an industrial application provisioning system that maintains a library of published industrial applications on a cloud platform. The provisioning system can return a subset of the published industrial application applications determined to be potentially relevant to the user's automation system.
