Description

Die Erfindung betrifft eine Stromversorgungs-Anschlussvorrichtung für ein parametrierbares elektrisches Gerät.The invention relates to a power supply connection device for a parameterizable electrical device.

Elektrische Geräte insbesondere in Anlagen weisen oft unterschiedliche Betriebsmöglichkeiten auf, die parametrisiert sind. Für den richtigen Betriebszustand müssen Parameter eingestellt werden. Diese werden an elektrischen Geräten oft lokal abgespeichert.Electrical devices, especially in systems often have different operating options that are parameterized. Parameters must be set for the correct operating state. These are often stored locally on electrical devices.

Der Erfindung liegt die Aufgabe zugrunde, eine Stromversorgungs-Anschlussvorrichtung mit erweiterten Einsatzmöglichkeiten bereitzustellen.The invention has for its object to provide a power supply connection device with extended capabilities.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst, wobei die Stromversorgungs-Anschlussvorrichtung für eine parametrierbares elektrisches Gerät einen ersten Anschluss für eine Stromquelle, einen zweiten Anschluss an das elektrische Gerät und eine Speichereinrichtung für Parameterdaten, welche durch das elektrische Gerät auslesbar sind, umfasst.This object is solved by the features of claim 1, wherein the power supply connection device for a parameterizable electrical device comprises a first connection for a power source, a second connection to the electrical device and a storage device for parameter data, which can be read by the electrical device ,

Eine Stromversorgungs-Anschlussvorrichtung sorgt für die Stromversorgung des entsprechenden elektrischen Geräts. Insbesondere sorgt sie für einen elektrischen Anschluss an ein Stromnetz. Eine Stromnetz-Anschlussvorrichtung stellt eine ortsabhängige elektrische Verbindung her aufgrund der Leitungslegung. Eine ausgewählte Stromversorgungs-Anschlussvorrichtung charakterisiert also einen gewissen Ort und damit auch das zugeordnete elektrische Gerät.A power supply connection device provides the power supply of the corresponding electrical device. In particular, it ensures an electrical connection to a power grid. A power grid connection device establishes a location-dependent electrical connection due to the wiring. A selected power supply connection device thus characterizes a certain location and thus also the associated electrical device.

Bei der erfindungsgemäßen Lösung ist die Stromversorgungs-Anschlussvorrichtung derart intelligent ausgebildet, dass das elektrische Gerät über die Stromversorgungs-Anschlussvorrichtung mit Parameterdaten versorgt werden kann. Dadurch kann ein elektrisches Gerät an einem bestimmten Ort, beispielsweise einer Anlage, mit den notwendigen Parameterdaten für dessen Betrieb versorgt werden.In the solution according to the invention, the power supply connection device is designed so intelligently that the electrical device can be supplied with parameter data via the power supply connection device. This can be an electrical device in a certain place, for example a plant, with the necessary parameter data for its operation.

Üblicherweise wird das Parametrieren von elektrischen Geräten beispielsweise bei einer Anlage nur einmal bei der Inbetriebnahme durchgeführt. Die entsprechenden Parameterdaten werden normalerweise in einem nicht flüchtigen Speicher des elektrischen Geräts gespeichert. Eine solche Anordnung wird in FR-A-2 913 149 beschriben. Wenn ein entsprechendes Gerät in einer Anlage während des Betriebs ausfällt, muss möglichst zeitnah ein Ersatzgerät eingebaut werden, um die Ausfallzeiten gering zu halten. Ein solches Ersatzgerät ist aber üblicherweise nicht richtig parametriert.Usually, the parameterization of electrical devices, for example, in a system is performed only once during commissioning. The corresponding parameter data is normally stored in a non-volatile memory of the electrical device. Such an arrangement is in FR-A-2 913 149 beschriben. If a corresponding device in a system fails during operation, a replacement device must be installed as soon as possible in order to minimize downtimes. However, such a replacement device is usually not correctly parameterized.

Bei der Lösung sind die korrekten Parameter für das entsprechende elektrische Gerät in der zugehörigen Stromversorgungs-Anschlussvorrichtung enthalten, welche beim Austausch des Geräts nicht ausgetauscht werden muss. Ein Ersatzgerät lässt sich dadurch auf schnelle Weise parametrieren, indem die Daten aus der Speichereinrichtung der Stromversorgungs-Anschlussvorrichtung eingelesen werden.In the solution, the correct parameters for the corresponding electrical device in the associated power supply connection device are included, which does not need to be replaced when replacing the device. A replacement device can thereby be parameterized in a rapid manner by reading the data from the memory device of the power supply connection device.

Es lassen sich dadurch zeitnah die geeigneten Parameter in das entsprechende elektrische Gerät einlesen und die Ausfallzeiten und damit auch Ausfallkosten einer Anlage lassen sich minimieren.In this way, the appropriate parameters can be promptly read into the corresponding electrical device and the downtimes and thus also the downtime costs of a system can be minimized.

Insbesondere umfasst die Speichereinrichtung mindestens einen nicht flüchtigen Speicher wie einen EEPROM. Dadurch lassen sich Parameterdaten fest speichern.In particular, the memory device comprises at least one nonvolatile memory, such as an EEPROM. This allows parameter data to be stored permanently.

Insbesondere ist der erste Anschluss von einem Stecker umfasst oder durch einen Stecker gebildet. Dadurch lässt sich die Stromversorgungs-Anschlussvorrichtung auf einfache Weise an ein Stromnetz anschließen.In particular, the first connection is comprised by a plug or formed by a plug. As a result, the power supply connection device can be easily connected to a power grid.

Aus dem gleichen Grund ist es günstig, wenn der zweite Anschluss von einem Stecker umfasst ist oder durch einen Stecker gebildet ist. Dadurch lässt sich die Stromversorgungs-Anschlussvorrichtung auf einfache Weise an ein elektrisches Gerät anschließen und auch, wenn beispielsweise ein Ersatzgerät bereitgestellt werden muss, auf einfache Weise von diesem elektrischen Gerät lösen.For the same reason, it is favorable if the second connection is encompassed by a plug or is formed by a plug. As a result, the power supply connection device can be easily connected to an electrical Connect device and even if, for example, a replacement device must be provided to easily solve this electrical device.

Ganz besonders vorteilhaft ist es, wenn die Speichereinrichtung an (insbesondere in) dem Stecker angeordnet ist und insbesondere in diesen integriert ist. Der Stecker stellt den notwendigen Raum für die Integration der Speichereinrichtung bereit. Ferner lassen sich dann auf einfache Weise Daten aus der Speichereinrichtung in das zugeordnete elektrische Gerät einlesen. Ferner ist auch auf einfache Weise ein Beschreiben der Speichereinrichtung der Stromversorgungs-Anschlussvorrichtung möglich.It is particularly advantageous if the storage device is arranged on (in particular in) the plug and in particular is integrated in the latter. The plug provides the necessary space for the integration of the storage device. Furthermore, data from the memory device can then be read into the associated electrical device in a simple manner. Furthermore, it is also possible to easily describe the storage device of the power supply connection device.

Bei einer Ausführungsform sitzt die Speichereinrichtung an einem Träger (welcher insbesondere in einem Innenraum eines Steckers angeordnet ist) und ist umspritzt. Dadurch ist die Speichereinrichtung geschützt angeordnet.In one embodiment, the storage device is seated on a carrier (which is arranged in particular in an interior of a plug) and is encapsulated. As a result, the storage device is arranged protected.

Vorteilhafterweise ist der Speichereinrichtung eine Schnittstelle zum Auslesen von Daten und/oder Einschreiben von Daten zugeordnet. Über die Schnittstelle lassen sich der Speichereinrichtung spezifische Parameterdaten bereitstellen bzw. über die Schnittstelle lassen sich einem elektrischen Gerät zu dessen Parametrisierung Parameterdaten zuführen.Advantageously, the memory device is associated with an interface for reading data and / or writing data. Via the interface, the storage device can be provided with specific parameter data or via the interface, parameter data can be supplied to an electrical device for its parameterization.

Günstig ist es, wenn ein dritter Anschluss zum Auslesen und/oder Beschreiben der Speichereinrichtung vorgesehen ist. Über den dritten Anschluss erfolgt der Datenaustausch mit dem elektrischen Gerät. Dieser kann unidirektional sein. Grundsätzlich ist es auch möglich, über den dritten Anschluss beispielsweise über ein getrenntes Programmiergerät oder auch über das elektrische Gerät die Speichereinrichtung zu beschreiben.It is favorable if a third connection is provided for reading out and / or writing to the memory device. The third connection is used to exchange data with the electrical device. This can be unidirectional. In principle, it is also possible to describe the memory device via the third connection, for example via a separate programming device or also via the electrical device.

Bei einer Ausführungsform ist der dritte Anschluss in den zweiten Anschluss integriert. Dadurch lässt sich die Anzahl der Komponenten für die Stromversorgungs-Anschlussvorrichtung gering halten. Es lässt sich bei entsprechender Ausbildung des elektrischen Geräts, wenn die Stromversorgungs-Anschlussvorrichtung angeschlossen ist, sowohl eine elektrische Energieversorgung als auch eine datenaustauschwirksame Ankopplung der Speichereinrichtung an das elektrische Gerät erreichen.In one embodiment, the third port is integrated with the second port. As a result, the number of components for the power supply connection device can be kept low. It can be with appropriate design of the electrical device when the power supply connection device is connected to achieve both an electrical power supply and a datenaustauschwirksame coupling of the memory device to the electrical device.

Bei einer Ausführungsform ist die erfindungsgemäße Stromversorgungs-Anschlussvorrichtung als Stromversorgungskabel mit mindestens einem Anschlussstecker ausgebildet. Es ergibt sich dadurch bei geringem Fertigungsaufwand eine einfache Möglichkeit zur Parametrierung von elektrischen Geräten beispielsweise in einer Anlage.In one embodiment, the power supply connection device according to the invention is designed as a power supply cable with at least one connector. This results in low production costs a simple way to parameterize electrical equipment, for example, in a system.

Es kann eine Anzeigeeinrichtung vorgesehen sein, welche der Speichereinrichtung der Stromversorgungs-Anschlussvorrichtung zugeordnet ist. Die Anzeigeeinrichtung, welche beispielsweise eine optische Anzeigeeinrichtung ist, kann anzeigen, ob eine Speichereinrichtung beschrieben ist bzw. wird oder nicht. Dadurch kann ein Bediener auf einfache Weise erkennen, ob eine Stromversorgungs-Anschlussvorrichtung Parameterdaten enthält oder nicht.There may be provided a display device which is associated with the storage device of the power supply connection device. The display device, which is, for example, an optical display device, can indicate whether or not a memory device is or will be described. Thereby, an operator can easily recognize whether a power supply terminal device contains parameter data or not.

Insbesondere ist die Stromversorgungs-Anschlussvorrichtung zur Ankopplung an ein Stromnetz wie beispielsweise ein Niederspannungs-Stromnetz vorgesehen. Dadurch können insbesondere elektrische Geräte wie beispielsweise Identifikationssysteme-Auswerteeinheiten an einer Anlage mit elektrischer Energie versorgt werden.In particular, the power supply connection device is provided for connection to a power grid such as a low-voltage power grid. As a result, in particular electrical devices such as identification system evaluation units can be supplied with electrical energy at a system.

Erfindungsgemäß ist eine Kombination einer Stromversorgungs-Anschlussvorrichtung mit einem Programmiergerät zum Beschreiben der Speichereinrichtung vorgesehen.According to the invention, a combination of a power supply connection device with a programming device for writing to the memory device is provided.

Durch das Programmiergerät lassen sich über einen entsprechenden Anschluss, welcher einen mechanischen/elektrischen Kontakt bereitstellt, Daten in die Speichereinrichtung der Stromversorgungs-Anschlussvorrichtung einlesen. Es ist auch eine drahtlose Datenübertragung möglich. Beispielsweise ist es auch möglich, dass über das Programmiergerät der Stromversorgung Daten aufmoduliert werden, um die Speichereinrichtung zu beschreiben. Erfindungsgemäß ist ferner eine Kombination aus elektrischem Gerät und Stromversorgungs-Anschlussvorrichtung vorgesehen.By means of the programming device, data can be read into the memory device of the power supply connection device via a corresponding connection, which provides a mechanical / electrical contact. It is also possible wireless data transmission. For example, it is also possible for data to be modulated via the programming device of the power supply in order to describe the memory device. According to the invention, a combination of electrical device and power supply connection device is further provided.

Eine solche Kombination weist die bereits oben beschriebenen Vorteile auf. Ferner lässt sich bei entsprechend ausgebildetem elektrischem Gerät auch eine Datenbeschreibung mit im elektrischen Gerät gespeicherten Parameterdaten der Stromversorgungs-Anschlussvorrichtung erreichen.Such a combination has the advantages already described above. Furthermore, a correspondingly designed electrical device can also be used to achieve a data description with parameter data of the power supply connection device stored in the electrical device.

Insbesondere ist die Stromversorgungs-Anschlussvorrichtung lösbar mit dem elektrischen Gerät verbindbar. Dadurch lässt sich bei Ausfall eines entsprechenden Geräts auf einfache Weise ein Ersatzgerät bereitstellen, welches "vor Ort" über die Stromversorgungs-Anschlussvorrichtung parametrierbar ist.In particular, the power supply connection device is detachably connectable to the electrical device. In this way, if a corresponding device fails, a replacement device can be provided in a simple manner, which can be parameterized "locally" via the power supply connection device.

Es kann dabei vorgesehen sein, dass das elektrische Gerät eine Speichereinrichtung für Parameterdaten aufweist, um beispielsweise entsprechende Betriebsparameter speichern zu können.It may be provided that the electrical device has a memory device for parameter data in order to be able to store, for example, corresponding operating parameters.

Erfindungsgemäß weist das elektrische Gerät eine Steuereinrichtung auf, welche das Einlesen und/oder Speichern von Parameterdaten steuert. Es ist dann beispielsweise möglich, bei einer Initialisierung des elektrischen Geräts zu prüfen, ob die Speichereinrichtung Parameterdaten enthält oder nicht. Wenn keine Parameterdaten enthalten sind, dann kann beispielsweise ein Einlesen von Parameterdaten aus der Speichereinrichtung der Stromversorgungs-Anschlussvorrichtung initiiert werden. Es ist grundsätzlich über die Steuereinrichtung auch möglich, Parameterdaten eines elektrischen Geräts zu verwenden, um diese in die Speichereinrichtung einer angeschlossenen Stromversorgungs-Anschlussvorrichtung einzuschreiben.According to the invention, the electrical device has a control device which controls the reading and / or storage of parameter data. It is then possible, for example, to check on initialization of the electrical device whether or not the memory device contains parameter data. If no parameter data is contained, then, for example, a reading of parameter data from the storage device of the power supply connection device can be initiated. In principle, it is also possible via the control device to use parameter data of an electrical device in order to write it into the memory device of a connected power supply connection device.

Günstigerweise liest die Steuereinrichtung bei der Initialisierung des elektrischen Geräts Daten aus der Speichereinrichtung der Stromversorgungs-Anschlussvorrichtung und/oder einer Speichereinrichtung des elektrischen Geräts aus. Dadurch wird sichergestellt, dass bei der Inbetriebnahme das elektrische Gerät die richtigen Daten erhält.The control device expediently reads data from the storage device of the power supply connection device and / or a storage device of the electrical device during the initialization of the electrical device out. This ensures that the electrical device receives the correct data during commissioning.

Es ist dabei möglich, dass mittels der Steuereinrichtung Daten aus der Speichereinrichtung des elektrischen Geräts an die Speichereinrichtung der Stromversorgungs-Anschlussvorrichtung übertragbar sind. Dadurch ist es beispielsweise auf einfache Weise möglich, dass, ohne dass ein externes Programmiergerät vorgesehen werden muss, die Parameterdaten eines elektrischen Geräts in die zugeordnete Stromversorgungs-Anschlussvorrichtung einzuspeichern. Wenn dann das elektrische Gerät ausgetauscht werden muss, dann erhält das neue Gerät seine Parameterdaten über die Stromversorgungs-Anschlussvorrichtung.It is possible that by means of the control device data from the storage device of the electrical device to the storage device of the power supply connection device can be transferred. This makes it possible, for example, in a simple manner that, without an external programming device must be provided to store the parameter data of an electrical device in the associated power supply connection device. If then the electrical device must be replaced, the new device receives its parameter data via the power supply connection device.

Es ist auch günstig, wenn das elektrische Gerät eine Schnittstelle für die Datenübertragung von der Stromversorgungs-Anschlussvorrichtung umfasst, um Daten von dort einlesen zu können.It is also advantageous if the electrical device comprises an interface for the data transmission from the power supply connection device in order to be able to read data from there.

Aus den oben genannten Gründen kann es günstig sein, wenn die Schnittstelle zur Datenübertragung von der Stromversorgungs-Anschlussvorrichtung ausgebildet ist. Dadurch kann eine "jungfräuliche" Stromversorgungs-Anschlussvorrichtung mit Parameterdaten direkt lokal an der Anwendung versorgt werden, d. h. das entsprechende elektrische Gerät kann seine Parameterdaten der Stromversorgungs-Anschlussvorrichtung bereitstellen, damit diese dort nicht flüchtig gespeichert werden, um so wiederum lokal die entsprechenden Parameterdaten außerhalb des elektrischen Geräts vorzuhalten.For the reasons mentioned above, it may be favorable if the interface for data transmission is formed by the power supply connection device. This allows a "virgin" power supply connection device with parameter data to be directly supplied locally to the application, i. H. the corresponding electrical device can provide its parameter data to the power supply connection device, so that they are not stored there in a volatile manner so as to locally again maintain the corresponding parameter data outside the electrical device.

Dieser erste Anschluss 12 ist beispielsweise als oder an einem Stecker ausgebildet. Über ihn ist die Stromversorgungs-Anschlussvorrichtung 10 beispielsweise an ein Stromnetz wie ein Niederspannungs-Industrienetz (+24 VDC) anschließbar.An embodiment of a power supply connection device according to the invention, which in FIG. 1 shown and designated therein by 10, comprises a first terminal 12. This first terminal 12 is formed for example as or on a plug. Via it, the power supply connection device 10 can be connected, for example, to a power network such as a low-voltage industrial network (+24 VDC).

Die Stromversorgungs-Anschlussvorrichtung 10 weist ferner einen zweiten Anschluss 14 auf. Dieser zweite Anschluss 14 ist insbesondere als oder an einem Stecker 16 ausgebildet. Über den zweiten Anschluss 14 ist die Stromversorgungs-Anschlussvorrichtung 10 an ein (parametrierbares) elektrisches Gerät 17 (Figur 3) anschließbar.The power supply connector 10 further includes a second terminal 14. This second connection 14 is designed in particular as or on a plug 16. Via the second connection 14, the power supply connection device 10 is connected to a (parameterizable) electrical device 17 (FIG. FIG. 3 ) connectable.

Der erste Anschluss 12 und der zweite Anschluss 14 sind durch ein Kabel 18 verbunden. In dem Kabel 18 sind von dem ersten Anschluss 12 zu dem zweiten Anschluss 14 Kabeladern 20a, 20b geführt.The first terminal 12 and the second terminal 14 are connected by a cable 18. In the cable 18, cable cores 20a, 20b are led from the first terminal 12 to the second terminal 14.

Der zweite Anschluss 14 weist jeweilige mit den Kabeladern 20a, 20b elektrisch leitend verbundene Stromversorgungsanschlussstellen 22a, 22b auf.The second terminal 14 has respective power supply terminals 22a, 22b electrically connected to the cable cores 20a, 20b.

Die Stromversorgungs-Anschlussvorrichtung 10 bildet ein Versorgungskabel für das elektrische Gerät 17, über welches das elektrische Gerät 17 mit elektrischer Energie versorgt wird.The power supply connection device 10 forms a supply cable for the electrical device 17, via which the electrical device 17 is supplied with electrical energy.

In dem zweiten Anschluss 14 ist ein Träger 24 beispielsweise in Form einer Platine angeordnet. An dem Träger 24 sitzt eine Speichereinrichtung 26, welche (mindestens) einen nicht flüchtigen Speicher für Daten hält. Der Speicher ist beispielsweise als EEPROM ausgebildet.In the second terminal 14, a carrier 24 is arranged, for example in the form of a circuit board. On the carrier 24 sits a memory device 26, which holds (at least) a non-volatile memory for data. The memory is designed for example as EEPROM.

Es kann dabei vorgesehen sein, dass der Speichereinrichtung 26 eine Anzeigeeinrichtung 28 zugeordnet ist. Die Anzeigeeinrichtung 28 ist beispielsweise eine optische Anzeigeeinrichtung, welche insbesondere eine oder mehrere Leuchtdioden umfasst. Durch die Anzeigeeinrichtung 28 kann beispielsweise angezeigt werden, ob der mindestens eine Speicher der Speichereinrichtung 26 beispielsweise Daten enthält oder nicht.It may be provided that the memory device 26 is associated with a display device 28. The display device 28 is, for example, an optical display device, which in particular comprises one or more light-emitting diodes. By the display device 28 can be displayed, for example, whether the at least one memory of the memory device 26, for example, contains data or not.

Die Stromversorgungs-Anschlussvorrichtung 10 weist an dem Stecker 16 einen dritten Anschluss 30 auf, über welchen Daten aus der Speichereinrichtung 26 auslesbar und dem elektrischen Gerät 17 bereitstellbar sind. Der dritte Anschluss 30 kann grundsätzlich auch genutzt werden, um Daten in die Speichereinrichtung 26 einzulesen.The power supply connection device 10 has, on the plug 16, a third connection 30, via which data can be read out of the storage device 26 and made available to the electrical device 17. The third connection 30 can in principle also be used to read data into the memory device 26.

Bei einer Ausführungsform ist der dritte Anschluss 30 in den zweiten Anschluss 14 integriert. Dementsprechend weist der zweite Anschluss 14 dann Anschlussstellen 32a, 32b, 32c auf, welche bei der Verbindung mit dem elektrischen Gerät 17 insbesondere zum Auslesen von Daten aus der Speichereinrichtung 26 und Einkopplung in das elektrische Gerät 17 dienen.In one embodiment, the third port 30 is integrated with the second port 14. Accordingly, the second connection 14 then has connection points 32a, 32b, 32c, which in particular serve for reading out data from the memory device 26 and coupling into the electrical device 17 when connected to the electrical device 17.

Die Stromversorgungs-Anschlussvorrichtung 10 weist an dem Stecker 16 eine Schnittstelle 34 auf, welche zur Kommunikation der Speichereinrichtung 26 mit dem elektrischen Gerät 17 dienen. Bei der Schnittstelle 34 handelt es sich beispielsweise um eine I2C-Schnittstelle, über die ein Lesen der Speichereinrichtung 26/Beschreiben der Speichereinrichtung 26 möglich ist.The power supply connection device 10 has an interface 34 on the plug 16, which serve to communicate the memory device 26 with the electrical device 17. The interface 34 is, for example, an I2C interface, via which reading of the memory device 26 / writing to the memory device 26 is possible.

Die Speichereinrichtung 26 ist in einem Innenraum 36 (Hohlraum) des Steckers 16 angeordnet. Sie ist auf geeignete Weise gekapselt. Beispielsweise ist sie umspritzt.The memory device 26 is arranged in an interior 36 (cavity) of the plug 16. It is encapsulated in a suitable manner. For example, she is overmoulded.

Zur Programmierung der Stromversorgungs-Anschlussvorrichtung 10, d. h. zum Einschreiben von Daten in die Speichereinrichtung 26, dient ein Programmiergerät 38 (Figur 2). Bei einer Ausführungsform umfasst dieses Programmiergerät 38 einen Anschluss 40, welcher direkt an den dritten Anschluss 30 anschließbar ist über entsprechenden mechanischen und elektrischen Kontakt. Über ein Datenfeld 42 oder dergleichen können dann entsprechende Daten in die Speichereinrichtung 26 eingeschrieben werden, die dort nicht flüchtig gespeichert werden.For programming the power supply connection device 10, ie for writing data into the memory device 26, a programming device 38 (FIG. FIG. 2 ). In one embodiment, this programming device 38 comprises a connection 40 which can be connected directly to the third connection 30 via corresponding mechanical and electrical contact. Via a data field 42 or the like, corresponding data can then be written to the memory device 26, which are not stored there in a volatile manner.

Es ist auch möglich, dass von dem Programmiergerät 38 Daten drahtlos in die Speichereinrichtung 26 eingeschrieben werden, wenn die Schnittstelle 34 entsprechend ausgebildet ist. Ferner ist es möglich, bei entsprechender Ausbildung der Schnittstelle 34, dass Daten in die Speichereinrichtung 26 eingeschrieben werden, welche den Kabeladern 20a, 20b zur Stromversorgung aufmoduliert werden.It is also possible that the programming device 38 writes data wirelessly into the memory device 26 when the interface 34 is designed accordingly. Furthermore, it is possible, if the interface 34 is designed accordingly, to write data into the memory device 26, which are modulated onto the cable cores 20a, 20b for the purpose of power supply.

Das elektrische Gerät 17 ist parametrierbar. Beispielsweise müssen zum Betrieb des Geräts 17 unterschiedliche Parameter eingestellt werden. Diese Parameter können in dem elektrischen Gerät 17 lokal abgespeichert werden.The electrical device 17 can be parameterized. For example, 17 different parameters must be set to operate the device. These parameters can be stored locally in the electrical device 17.

Die Parameter für das elektrische Gerät 17 können beispielsweise auch Parameter umfassen, welche charakteristisch sind für den Platz des elektrischen Geräts 17 in einem Netzwerk.For example, the parameters for the electrical device 17 may also include parameters that are characteristic of the location of the electrical device 17 in a network.

Entsprechende Parameter könnten beispielsweise auch Initialisierungsparameter umfassen, die sicherstellen, dass das Gerät nach einem Neustart in den richtigen Betriebszustand übergeht.Corresponding parameters could include, for example, initialization parameters that ensure that the device transitions to the correct operating state after a restart.

Wenn an einer Anlage, welche mehrere elektrische Geräte umfasst, ein Gerät ausgetauscht werden muss, dann muss das neu eingesetzte Gerät die entsprechenden Parameter erhalten. Bei der erfindungsgemäßen Lösung werden einem solchen elektrischen Gerät 17 die Parameter über die ohnehin notwendige Stromversorgungs-Anschlussvorrichtung 10 bereitgestellt, über welche das elektrische Gerät auch mit elektrischer Energie versorgt wird.If a device has to be replaced on a system that includes several electrical devices, then the newly installed device must receive the corresponding parameters. In the solution according to the invention, the parameters of such an electrical device 17 are anyway necessary Power supply connection device 10 is provided, via which the electrical device is also supplied with electrical energy.

Das elektrische Gerät 17 umfasst eine Steuereinrichtung 44, welche signalwirksam mit dem dritten Anschluss 30 der Stromversorgungs-Anschlussvorrichtung 10 verbunden ist. Über diese Steuereinrichtung ist das Einlesen von Daten aus der Speichereinrichtung 26 steuerbar. Beispielsweise steuert die Steuereinrichtung 44, dass bei der Initialisierung des elektrischen Geräts 17 Daten aus der Speichereinrichtung 26 der Stromversorgungs-Anschlussvorrichtung 10 eingelesen werden.The electrical device 17 includes a control device 44, which is signal-effectively connected to the third terminal 30 of the power supply connection device 10. The reading in of data from the memory device 26 can be controlled via this control device. For example, the control device 44 controls that data is read in from the storage device 26 of the power supply connection device 10 during the initialization of the electrical device 17.

Das elektrische Gerät 17 weist insbesondere eine Speichereinrichtung 46 auf, in welcher entsprechende Parameterdaten gespeichert sind. Insbesondere ist die Speichereinrichtung 46 an die Steuereinrichtung 44 gekoppelt, so dass aus der Speichereinrichtung 26 ausgelesene Parameterdaten in der Speichereinrichtung 46 speicherbar sind.The electrical device 17 has, in particular, a memory device 46 in which corresponding parameter data are stored. In particular, the memory device 46 is coupled to the control device 44, so that parameter data read from the memory device 26 can be stored in the memory device 46.

Es ist dabei grundsätzlich auch möglich, dass die Steuereinrichtung 44 benutzt wird, um Daten in die Speichereinrichtung 26 der Stromversorgungs-Anschlussvorrichtung 10 einzuschreiben. Die Steuereinrichtung bewirkt dabei, dass Daten aus der Speichereinrichtung 46 ausgelesen werden und in die Speichereinrichtung 26 geschrieben werden. Dadurch kann beispielsweise eine "neue" Stromversorgungs-Anschlussvorrichtung 10 direkt von einem elektrischen Gerät 17 mit nicht flüchtiger Speichereinrichtung 46 Parameterdaten aufnehmen und später, wenn das elektrische Gerät 17 ausgetauscht wird, diese Parameterdaten einem neuen elektrischen Gerät bereitstellen.It is basically also possible that the control device 44 is used to write data into the memory device 26 of the power supply connection device 10. In this case, the control device causes data to be read from the memory device 46 and written to the memory device 26. Thus, for example, a "new" power connector 10 may receive parameter data directly from an electrical device 17 with nonvolatile memory 46 and later, when the electrical device 17 is replaced, provide that parameter data to a new electrical device.

Das elektrische Gerät 17 weist entsprechend eine Schnittstelle 48, welche an die Schnittstelle 34 angepasst ist, auf, um Daten von der Stromversorgungs-Anschlussvorrichtung 10 empfangen zu können und gegebenenfalls Daten an die Speichereinrichtung 26 senden zu können.The electrical device 17 accordingly has an interface 48, which is adapted to the interface 34, in order to be able to receive data from the power supply connection device 10 and, if appropriate, to be able to send data to the memory device 26.

Ein Beladen der Speichereinrichtung 26 mit Daten bzw. eine beladene Speichereinrichtung 26 wird insbesondere durch die Anzeigeeinrichtung 28 angezeigt. Dadurch kann ein Anwender bzw. Bediener einer Anlage erkennen, ob eine Stromversorgungs-Anschlussvorrichtung 10 bezüglich der Datenspeicherung "angeschaltet" ist.A loading of the memory device 26 with data or a loaded memory device 26 is indicated in particular by the display device 28. As a result, a user or operator of a system can recognize whether a power supply connection device 10 is "switched on" with regard to data storage.

Bei der Initialisierung eines elektrischen Geräts 17 prüft die Steuereinrichtung 44 beispielsweise, ob Parameterdaten in der Speichereinrichtung 46 gespeichert sind. Ist dies nicht der Fall, dann sorgt sie dafür, dass Daten von der Speichereinrichtung 26 der Stromversorgungs-Anschlussvorrichtung 10 eingelesen werden.During the initialization of an electrical device 17, the control device 44 checks, for example, whether parameter data is stored in the memory device 46. If this is not the case, then it ensures that data is read in from the storage device 26 of the power supply connection device 10.

Ein möglicher Anwendungsfall für ein elektrisches Gerät 17 ist eine Auswerteeinheit für ein Identifikationssystem.One possible application for an electrical device 17 is an evaluation unit for an identification system.

Durch die erfindungsgemäße Lösung wird eine intelligente Stromversorgungs-Anschlussvorrichtung 10 beispielsweise in Form eines Versorgungskabels bereitgestellt, welches einem elektrischen Gerät 17 Parameter übermitteln kann. Wenn dann beispielsweise das elektrische Gerät insbesondere in einer Anlage während des Betriebs ausfällt, dann kann zeitnah ein Ersatzgerät eingebaut werden, welches nicht aufwendig extern parametrisiert werden muss, sondern die Parameter von der verbliebenen Stromversorgungs-Anschlussvorrichtung 10 übernehmen kann. Dadurch lassen sich die Ausfallzeiten und damit auch Ausfallkosten gering halten.The inventive solution provides an intelligent power supply connection device 10, for example in the form of a supply cable, which can transmit parameters to an electrical device 17. If then, for example, the electrical device fails in particular in a system during operation, then a replacement device can be installed in a timely manner, which does not have to be externally parametrized consuming, but can take over the parameters of the remaining power supply connection device 10. As a result, the downtime and thus downtime costs can be kept low.

Auch wenn eine Vielzahl von elektrischen Geräten an einer Anlage vorgesehen sind, lässt sich eine einfache und schnelle Parametrisierung von "nackten" Austauschgeräten durchführen, da die Stromversorgungs-Anschlussvorrichtungen 10 an der Anlage ortsspezifisch sind (aufgrund der notwendigen Kabelführung).Even if a large number of electrical devices are provided on a system, a simple and rapid parameterization of "bare" replacement devices can be carried out, since the power supply connection devices 10 are location-specific to the system (due to the necessary cable routing).

Es kann dadurch gewissermaßen vor Ort eine Parametereinstellung von neu eingesetzten elektrischen Geräten 17 durchgeführt werden, ohne dass das elektrische Gerät selber aufwendig programmiert werden muss. Die erfindungsgemäße Stromversorgungs-Anschlussvorrichtung 10 erlaubt eine schnelle Parametrierung von Austauschgeräten.It can thus be carried out to a certain extent locally a parameter setting of newly inserted electrical equipment 17, without that electrical device itself must be programmed consuming. The power supply connection device 10 according to the invention allows fast parameterization of replacement devices.

Ferner ist es auch auf einfache Weise möglich, die Parameter in die Stromversorgungs-Anschlussvorrichtung 10 einzuschreiben. Beispielsweise wird bei einem Neustart eines elektrischen Geräts 17 geprüft, ob bereits Parameter in der Speichereinrichtung 46 enthalten sind. Ist dies nicht der Fall, dann sorgt die Steuereinrichtung 44 dafür, dass Parameter von der Speichereinrichtung 26 der Stromversorgungs-Anschlussvorrichtung 10 eingelesen werden und in die Speichereinrichtung 46 eingeschrieben werden. Das entsprechende elektrische Gerät 17 lässt sich dann in den richtigen Betriebszustand versetzen.Furthermore, it is also easily possible to write the parameters in the power supply terminal device 10. For example, upon restart of an electrical device 17 it is checked whether parameters are already contained in the memory device 46. If this is not the case, then the control device 44 ensures that parameters are read from the memory device 26 of the power supply connection device 10 and written into the memory device 46. The corresponding electrical device 17 can then be put into the correct operating state.

Die Steuereinrichtung 44 kann beispielsweise auch einen Steuer-Marker steuern, welcher signalisiert, ob insbesondere bei der ersten Inbetriebnahme Parameter aus der Speichereinrichtung 46 übernommen werden sollen und auf die Speichereinrichtung 26 übertragen werden sollen.The control device 44 can, for example, also control a control marker, which signals whether, in particular during the first startup, parameters from the memory device 46 are to be taken over and transferred to the memory device 26.

Wie oben erwähnt ist es auch grundsätzlich möglich, die Speichereinrichtung 26 mit Daten über ein Programmiergerät 38 zu versehen, welches unabhängig von einem elektrischen Gerät 17 ist.As mentioned above, it is also basically possible to provide the memory device 26 with data via a programming device 38, which is independent of an electrical device 17.
