Definitions
- the invention relates to an automation system, in particular an automation system with distributed components, each of which has its own functionality.
- Automation systems are usually parameterized manually by a project engineer.
- the project engineer needs to know the individual automation devices of the automation system with their properties and functionalities. Interface descriptions of the automation devices are often only available in paper form or in the form of online help.
- the object of the invention is to simplify the provision of information within an automation system.
- a directory service in an automation system for providing information about access options, functionalities, interfaces and topologies of components of the automation system, the directory service being web service-based.
- the proposed invention offers a directory service which has knowledge of the components of an automation system and their functionality has.
- clients are implemented in such a way that they can operate less generically. They are usually programmed and configured precisely against the existing devices.
- the directory service according to the invention has the advantage that the usual 1: 1 relationship (direct linking) between a client and the automation components used by this client is no longer necessary.
- the directory service is based on WebService.
- such a directory service can be designed as a central directory service on a server, e.g. B. in the form of a central XML-based information service based on UDDI (Universal Discovery Description and Integration) in the web server vice environment, here adapted to the needs of automation technology.
- a server e.g. B. in the form of a central XML-based information service based on UDDI (Universal Discovery Description and Integration) in the web server vice environment, here adapted to the needs of automation technology.
- UDDI Universal Discovery Description and Integration
- search service a search service used within the directory service to search for components and / or functionalities of the automation system is provided.
- the directory service has means for self-registration of components and / or functionalities of the automation system.
- Automation devices or components can thus register themselves with the central directory service.
- self-registration of web services provided by the automation device can also be entered in the directory service.
- the directory service is not necessarily implemented as a central instance, but can e.g. B. to increase redundancy, run as a distributed service (e.g. as a cluster, web farm, decentralized database, etc.).
- a distributed service e.g. as a cluster, web farm, decentralized database, etc.
- the figure shows a schematic representation of the principle of using a directory service in a distributed automation system.
- the distributed system contains various operator control and monitoring systems 51 to 53, distributed automation systems 54 to 57 and a central directory service 58. Communication between operator control and monitoring systems 51 to 53 and automation systems 54 to 57 takes place via an Internet and / or intranet 50 Different automation systems 54 to 57 can be spatially spaced apart from one another. Access to components 70 through 78 of the auto Automation systems 54 to 57 are carried out via web services 60 to 68.
- the operating and monitoring systems 51, 52 and 53 are designed as part of a control room or as a mobile personal digital assistant (PDA) of a service technician.
- PDA mobile personal digital assistant
- communication via the Internet and / or intranet 50 takes place not only between the operating and monitoring systems 51 to 53 and the automation systems 54 to 57 but also between the individual automation systems 54 to 57 or between the components 70 to 78 of the automation systems.
- Components 70 to 78 of the automation system each have at least one interface for message and port-based access to at least one application provided by the respective components 70 to 78.
- these applications are implemented as web services 60 to 68.
- Such a WebService 60 to 68 provides a certain functionality, uses Internet mechanisms and is stateless.
- the interfaces of the components of the automation system are described by meta information.
- An interface can, for example, be designed as an XML interface.
- an “Automation Directory Discovery and Integration” (ADDI) is defined as the central directory service 58.
- UDDI does not meet the requirements of automation technology, since it is optimized for e-business services Automation specifics are specifically taken into account.
- UDDI schemas and functionalities are expanded for the ADDI directory service 58 and thus enable the use of the UDDI mechanisms / clients in the automation environment as well from UDDI.
- the service Descriptions of the automation devices, components 70 to 78 and applications 60 to 68 can be stored.
- system data is made available via a uniform mechanism enables generic applications to be created.
- These can use the directory service 58 (ADDI) to browse, for example, a plant structure, to find components and interfaces and / or to provide services.
- ADPI directory service
- generic applications (not possible today), in particular for standardized functionalities such as diagnosis, download, parameterization, etc. can be created. Due to the plant structure stored in the directory service 58, this can serve as a central information instance for devices present in a plant, in an automation system. This enables a wide range of information to be provided, from browsing through the existing system to requests for firmware versions on individual devices.
- the applications (services) offered by automation devices are described in a uniform manner (e.g.
- the implementation of services in automation devices can be memory-optimized because metal information about (automation) devices, applications and / or web services is stored and managed centrally.
- the proposed directory service 58 also serves as the basis for the establishment of consolidation services. Additional services are possible on the basis of the data available in the directory service 58. Data is available or can be stored for totals, maintenance analysis, efficiency analyzes on the automation system, on levels or cells.
- search service query service
- questions can be answered such as: B.:, Which Services does the automation device 4711 offer in hall 3? ' or, search for all devices that offer the standard diagnostic service! '.
- the automation device or the automation component provides the directory service 58 with information about all offered web services 60 to 68 as part of a discovery process (UPNP - Universal Plug and Play).
- the directory service 58 uses a standardized service to query the web services 60 to 68 provided by the automation system after the discovery phase of the respective automation device 70 to 78. This can be done, for example, via standardized web service interfaces of the automation devices 70 to 78.
- the discovery phase can also consist in the fact that the addressing of the respective device is entered manually / partially automatically in the directory service 58 and the directory service 58 then automatically asks the device about its services. So not only the existence of automation devices 70 to 78, but above all their functionality is registered.
- the registration can also be carried out conventionally, in that the data from a configuration or an engineering system is transferred directly to the directory service 58.
- This technology allows both direct communication between applications (the so-called services) as well as the construction of applications from distributed components (again services), ie loosely connected web services can work together to fulfill a task.
- standards such as XML and SOAP
- the WebService technology scales from local communication to communication via the intra- net / Internet. It is the basis for distributed and integrated Internet applications, using existing standards (e.g. W3C, IETF standards such as HTTP, XML, XML Schema, XML Data Types, etc.) or new ones, together with W3C, IETF defines standards such as SOAP, WSDL, UDDI.
- Web service interfaces are described by meta information (methods, parameters (names and types)), usually in WSDL (Web Service Description Language). This complete interface description is sufficient to call up the web services. It describes the end point (port) at which the respective web service can be called and is particularly useful for automatic communication with web services.
- WebServices are easy to access, blurring the lines between local APIs and WebServices ("Web APIs"). Access is just as easy as when creating and using a local object.
- WebService technology is the basis for loosely coupled applications. It is characterized by message-based communication and scalability through statelessness. The loose coupling (e.g. with SOAP) offers the advantages of good compatibility with changes in the implementation of the client and server and robust communication (port-based, message-based, asynchronous).
- a client packs messages into self-describing packets (messages) and sends them over the respective communication connection.
- the sender and receiver only have an agreement with regard to the message format used on the line. The only assumption is that the recipient understands the message. No assumptions are made about what happens after the message is received or between the sender and recipient.
- Common web services have the following properties: They are accessible via a communication network such as the Internet / intranet and have an XML interface. Information about WebServices is stored in a registry so that the WebServices can be localized via it. They communicate using XML messages Web protocols and support loosely coupled connections between systems.
- the invention thus relates to a directory service 58 which simplifies the provision of information within an automation system.
- the directory service 58 is used to provide information about access options, functionalities, interfaces and topologies of components of the automation system and is web service-based.
