Furthermore, the invention relates toa universal, distributed and consistent automation and management engineering and information system.
Ein Automatisierungsgerät mit den Merkmalen des Oberbegriffs des Anspruchs 1 ist aus dem Siemens-Katalog ST 70, Ausgabe1995, bekannt. Ein Anwender erstellt mit einem Programmiergerät ein Programm zur Steuerung eines technischen Prozesses,das Software-Funktionsbausteine, z. B. in Form von Organisationsbausteinen, Programmbausteinen und Instanzdatenbausteinen,umfaßt. Das Automatisierungsgerät ist mit dem Programmiergerät über ein Bussystem verbunden, über welches dasProgrammiergerät das Steuerprogramm in das Automatisierungsgerät überträgt.

A user uses a programming device to create a program for controlling a technical process, which includes software function blocks, e.g. in the form of organization blocks, program blocks and instance data blocks. The automation device is connected to the programming device via a bus system, via which the programming device transfers the control program to the automation device. Furthermore, an operating and monitoring device can be connected to the bus system, which is intended for process control and which enables the display of process images comprising several image objects.
Häufig ist es erforderlich, daß Software-Funktionsbausteine eines Steuerprogramms von einem Automatisierungsgerät einesFertigungsStandortes oder aus einem Software-Pool dieses Fertigungsstandortesin ein Automatisierungsgerät eines anderen Fertigungsstandortes zu übertragen sind. Insbesondere wenndie Fertigungsstandorte sehr weit voneinander entfernt sind, z.B. wegen einer Globalisierung von Fertigungsaktivitäten,werden diese Software-Funktionsbausteine über das globale Netzwerk „INTERNET" übertragen. Dazu sind Server mit geeignetenKommunikationsschnittstellen notwendig, die einerseits das INTERNET-Kommunikationsprotokoll und andererseits dasKommunikationsprotokoll der Automatisierungsgeräte ermöglichen. Aufgrund dieser unterschiedlichen Protokolle und derArchitektur der Automatisierungsgeräte ist eine EinbindungIt is often necessary for software function blocks of a control program to be transferred from an automation device at aproduction site or from a software pool at this production site to an automation device at another production site. In particular, ifthe production sites are very far apart, e.g. due to globalization of production activities,these software function blocks are transferred via the global network "INTERNET". For this purpose, servers with suitablecommunication interfaces are required, which on the one hand enable the INTERNET communication protocol and on the other hand thecommunication protocol of the automation devices. Due to these different protocols and thearchitecture of the automation devices, integration

Zwei Fertigungsstandorte 1 und 2 eines global verteilten Automatisierungsverbundes sind über ein an sich bekanntesglobales Netzwerk „INTERNET" 3 miteinander verbunden, wobei geeignete Einrichtungen 4, 5 vorgesehen sind, die verhindern,daß Unberechtigte Daten in die datenverarbeitenden Komponenten der Fertigungsstandorte 1, 2 übertragen. Die Fertigungsstandorte1, 2 umfassen mehrere jeweils mit einer INTERNET-Kommunikationsschnittstelleversehene Geräte in Form von Automatisierungsgeräten 6, Programmiergeräten 7, Bedien- undBeobachtungsgeräten 8 und Workstations 9. Diese INTERNET-Kommunikationsschnittsteilenermöglichen eine TCP/IP-Protokoll -Kommunikation der Geräte untereinander. Es ist einewesentliche Anforderung an ein Automatisierungsgerät, das während eines Steuerbetriebs ein aus mehreren Software-Funktionsbausteinengebildetes Steuerprogramm zyklisch und/oder interruptgesteuert und/oder prioritätsgesteuert bearbeitet,daß diese Software-Funktionsbausteine ladbar und zur Laufzeit des Steuerprogramms in dieses einbindbar ausgebildet sind.Damit diese Anforderung erfüllt ist und die Software-Funktionsbausteineüber das INTERNET und die INTERNET-Kommunikationsschnittstelle direkt in ein Automatisierungsgerät ladbarund zur Laufzeit des Steuerprogramms in dieses einbindbar sind, sind die Software-Funktionsbausteine objektorientiertausgebildet. Die Software-Funktionsbausteine sind über das INTERNET dynamisch ladbar und erweiterbar, und das Automatisierungsgerätist mit einer Software-Funktionsbaustein-Ablaufsteuerungversehen, die diese Software-Funktionsbausteine während des Steuerbetriebs bearbeitet.Eine Programmiersprache, die einen objektorientierten Code0 aus einer Quellsprache erzeugt und für einen Einsatz im INTERNET vorgesehen ist, ist aus dem Buch „Java!",Tim Ritchey, published 1995 by New Riders Publishing, bekannt. Dort ist eine Quellsprache „JAVA C" beschrieben, ausder ein objektorientierter Java-Bytecode erzeugbar ist. Weitere vorteilhafte Eigenschaften dieses Sprachmittels sindinsbesondere die Portabilität des Codes sowie die Mechanismen zur Fehlerbehandlung. Durch die Portabilität des Codes wirdTwo production sites 1 and 2 of a globally distributed automation network are connected to one another via a known global network "INTERNET" 3, whereby suitable devices 4, 5 are provided to prevent unauthorized persons from transferring data to the data processing components of the production sites 1, 2. The production sites 1, 2 comprise several devices, each provided with an INTERNET communication interface, in the form of automation devices 6, programming devices 7, operating and monitoring devices 8 and workstations 9. These INTERNET communication interfaces enable TCP/IP protocol communication between the devices. It is an essential requirement for an automation device that processes a control program made up of several software function blocks cyclically and/or interrupt-controlled and/or priority-controlled during control operation that these software function blocks can be loaded and can be integrated into the control program during runtime. are designed to be integrable.In order to meet this requirement and so that the software function blockscan be loaded directly into an automation device via the INTERNET and the INTERNET communication interfaceand can be integrated into the control program during runtime, the software function blocks are designed to be object-oriented. The software function blocks can be dynamically loaded and expanded via the INTERNET, and the automation deviceis provided with a software function block sequence controlthat processes these software function blocks during control operation.A programming language that generates an object-oriented code0 from a source language and is intended for use on the INTERNET is known from the book "Java!",Tim Ritchey, published 1995 by New Riders Publishing. There a source language "JAVA C" is described, from which an object-oriented Java bytecode can be generated. Other advantageous properties of this language tool arein particular the portability of the code and the mechanisms for error handling. The portability of the code makes

sichergestellt, daß ein Automatisierungsgerät mit einer Ablaufsteuerungin Form eines Java-Bytecode-Interpreters 10 unabhängig von einer Prozessor-Hardware-Architektur 11 desAutomatisierungsgerätes (herstellerunabhängig) die dem Automatisierungsgerätüber das INTERNET zugeführten Java-Funktionsbausteine bearbeiten kann. Aus Gründen der Performanceist es allerdings vorteilhaft, das Automatisierungsgerät mit einem Java-Prozessor 12 zu versehen, der den Java-Code direktverarbeitet.ensures that an automation device with a sequence control in the form of a Java bytecode interpreter 10 can process the Java function blocks supplied to the automation device via the INTERNET, independent of a processor hardware architecture 11 of the automation device (independent of the manufacturer). For performance reasons, however, it is advantageous to provide the automation device with a Java processor 12 that processes the Java code directly.
Die Portabilität eines objektorientierten Codes wird in Figur2 verdeutlicht, in der ein Programmübersetzungs-Strukturbild dargestellt ist.
Ein Anwender erstellt mit einem Programmiergerät nach Maßgabe einer zu lösenden Steueraufgabe ein Steuerprogramm in Formeines Kontaktplanes KOP, eines Funktionsplans FuP, einer Anweisungsliste AWL oder in einer sonstigen geeigneten, z. B.in der Norm IEC 1131 beschriebenen, Form. Das Programmiergerät übersetzt auf Anwenderebene das Steuerprogramm in eineQuellsprache Qu, z. B. in die Quellsprache „JAVA C", oder direkt (in der Figur mit unterbrochenen Linien dargestellt) ineine objektorientierte Maschinensprache Ms, z. B. in den Java-Bytecode, die in Automatisierungsgeräte AGl, AG2, AG3,AG4 unterschiedlicher Architektur geladen wird. Auf Anwenderebene ist zur Erstellung der Maschinencodes nur ein Compilerfür alle Automatisierungsgerate erforderlich. Es ist angenommen, daß das Automatisierungsgerät AG4 einen Codegenerator CGfür die Verarbeitung der Maschinensprache Ms aufweist, wodurch dieses Automatisierungsgerät AG4 den Code direkt verarbeitenkann. Ferner ist angenommen, daß die Automatisierungsgerate AGl, AG2, AG3 nicht mit einem derartigen Codegeneratorversehen sind, sondern unterschiedliche Prozessoren PRl, PR2, PR3 umfassen. Damit die Automatisierungsgeräte AGl,AG2, AG3 den Code MS verarbeiten können, sind diese Automatisierungsgeräte jeweils mit einem Code-Interpreter IPl, IP2,IP3 versehen. Diese Interpreter IPl, IP2, IP3 erzeugen wäh-The portability of an object-oriented code is illustrated in Figure 2, which shows a program translation structure diagram.
A user uses a programming device to create a control program in the form of a ladder diagram (LD), a function block diagram (FuP), an instruction list (IL) or another suitable form, e.g. as described in the IEC 1131 standard, in accordance with a control task to be solved. The programming device translates the control program at user level into a source language (Qu), e.g. B. into the source language "JAVA C", or directly (shown in the figure with broken lines) into an object-oriented machine language Ms, e.g. into the Java byte code, which is loaded into automation devices AG1, AG2, AG3, AG4 of different architectures. At the user level, only one compiler is required for all automation devices to create the machine codes. It is assumed that the automation device AG4 has a code generator CG for processing the machine language Ms, whereby this automation device AG4 can process the code directly. It is also assumed that the automation devices AG1, AG2, AG3 are not provided with such a code generator, but have different processors PR1, PR2, PR3. So that the automation devices AG1, AG2, AG3 can process the code MS, these automation devices are each provided with a code interpreter IP1, IP2, IP3. These interpreters IP1, IP2, IP3 generate

Die Programmierung der objektorientierten Software-Funktionsbausteineerfolgt durch die jeweiligen Programmiergeräte 7 {Figur 1) der Fertigungsstandorte 1, 2 oder durch ein ebenfallsan das INTERNET angeschlossenes Programmiergerät 14.Neben den Bedien- und Beobachtungsgeräten 8 und den Workstations 9 sind diese Programmiergeräte 8, 14 Bestandteiledes Management-Engineering-Systems. Die Programmiergeräteführen diese Softwarebausteine den entsprechenden Automatisierungsgeräten über die jeweilige INTERNET-Kommunikationsschnittstelleund das INTERNET zu. Für den Fall, daß z. B. Bausteine geändert werden müssen, überträgt zunächst dasAutomatisierungsgerät 6 oder ein Server 13 einem der Programmiergeräte 7 den entsprechenden Software-Funktionsbausteinüber das INTERNET. Schließlich ergänzt bzw. modifiziert das Programmiergerät 7 diesen Baustein und kann ihn wieder ineines der Automatisierungsgeräte übertragen.The programming of the object-oriented software function blocks is carried out by the respective programming devices 7 (Figure 1) of the production sites 1, 2 or by a programming device 14 that is also connected to the INTERNET. Along with the operating and monitoring devices 8 and the workstations 9, these programming devices 8, 14 are components of the management engineering system. The programming devices send these software blocks to the corresponding automation devices via the respective INTERNET communication interface and the INTERNET. In the event that, for example, blocks need to be changed, the automation device 6 or a server 13 first transfers the corresponding software function block to one of the programming devices 7 via the INTERNET. Finally, the programming device 7 supplements or modifies this block and can transfer it back to one of the automation devices.
Die Prozeßbedienung und ProzeSführung der zu steuernden Prozesse in den Fertigungsstandorten 1, 2 erfolgt durch ebenfallsan das INTERNET anschlieSbare und am INTERNET betreibbare Bedien- und Beobachtungsgeräte 8. Ein Bedien- und Beobachtungsgerät8, z. B. das Bedien- und Beobachtungsgerät 8 des Fertigungsstandortes 1, erzeugt ein Bedien- und Beobachtungs-Softwarebausteineumfassendes Bedien- und Beobachtungsprogramm zur Erstellung und Darstellung eines mehrere Bildobjekteumfassenden Prozeßbildes, wobei die Bildobjekte zu Software-Funktionsbausteinen des Steuerprogramms in Beziehung{in Wechselwirkung) stehen. Die Bedien- und Beobachtungs-Softwarebausteinesind objektorientiert ausgebildet und direkt über das INTERNET übertragbar. Es ist selbstverständlichmöglich, das Prozeßbild auf dem Programmiergerät 7 zu erstellen und zur Prozeßführung über das INTERNET dem Bedien- undBeobachtungsgerät 8 zuzuführen.The process operation and process control of the processes to be controlled in the production locations 1, 2 is carried out by operating and monitoring devices 8 that can also be connected to and operated on the INTERNET. An operating and monitoring device 8, e.g. the operating and monitoring device 8 of the production location 1, generates an operating and monitoring program that includes operating and monitoring software modules for creating and displaying a process image that includes several image objects, whereby the image objects are related to software function modules of the control program. The operating and monitoring software modules are object-oriented and can be transferred directly over the INTERNET. It is of course possible to create the process image on the programming device 7 and to feed it to the operating and monitoring device 8 for process control over the INTERNET.

Um in Automatisierungssystemen hohen Ausbaugrades die Anzahl der in ein Automatisierungsgerät eingebauten Ein- und Ausgabekomponentenzu verringern, werden dezentrale Subsysteme, z. B. in Form von intelligenten Feldgeräten, eingesetzt. Dasverteilte Automatisierungs- und Management-Engineering-Systemweist ein hier nicht dargestelltes intelligentes Feldgerät auf, in welches ein objektorientierter Software-Funktionsbausteinüber das INTERNET und eine INTERNET-Kommunikationsschnittstelle des Feldgerätes ladbar ist, wobei das Feldgerätmit einem Software-Funktionsbaustein-Ablaufsystem (PLC-Object-Engine-System) zur Bearbeitung dieses Funktionsbausteinsversehen ist.In order to reduce the number of input and output components built into an automation device in highly sophisticated automation systems, decentralized subsystems, e.g. in the form of intelligent field devices, are used.
