Abstract
Description
Die Erfindung betrifft ein Bus-System zum Vernetzen der Fühler und weiteren Komponenten einer Bahnlaufregeleinrichtung, wie z. B. Stellmotoren für die Fühler und dergleichen, sowie ein Verfahren zum Konfigurieren der Bahnlaufregeleinrichtung.The invention relates to a bus system for networking the sensor and other components of a web guiding device, such. As servomotors for the sensors and the like, and a method for configuring the web guiding device.
Bei einer Bahnlaufregeleinrichtung werden z. B. beiderseits einer laufenden Materialbahn Fühler, wie z. B. optische Fühler oder Ultraschall-Fühler, Fühler an einer oder mehreren Stellen angeordnet, die die Ausrichtung der Materialbahn überwachen und Signale an eine Regeleinrichtung übermitteln, durch die Stellorgane wie Umlenkrollen oder Drehrahmen für die Materialbahn angesteuert werden, damit die Stellorgane die Materialbahn auf der vorgegebenen Bahnausrichtung halten.In a web guiding device z. B. both sides of a running material web sensor, such. As optical sensors or ultrasonic sensors, sensors arranged at one or more locations that monitor the orientation of the web and transmit signals to a control device, are controlled by the actuators such as pulleys or rotating frame for the web so that the actuators the web on the keep predetermined track alignment.
Bei der bekannten Bus-Topologie, wie sie in
Dies ist bei jeder Neuinstallation einer Regeleinrichtung mit einem gewissen Aufwand verbunden und im Fall des Austausches einer Komponente, z. B eines Fühlers, bei einer bereits installierten Regeleinrichtung muss man der neu hinzukommenden Komponente eine Adresse eingeben, bevor man die Komponente durch Anschluß an der jeweiligen Buchse
Mit der erfindungsgemäßen Ausgestaltung soll die Installation einer Bahnlaufregeleinrichtung und auch ein Austausch von Komponenten an einer vorhandenen Regeleinrichtung vereinfacht werden.With the embodiment according to the invention, the installation of a web guiding device and also an exchange of components to an existing control device to be simplified.
Dies wird dadurch erreicht, dass die Komponenten im Bus-System sternförmig verdrahtet und angesteuert werden, wobei von einer Verteilerstelle aus zu jeder Komponente ein gesonderter Leitungsstrang führt. Der an den Leitungsstrang angeschlossenen Komponente wird eine entsprechende Adresse zugeordnet. Dadurch ist die an diesem Leitungsstrang angeschlossene Komponente später eindeutig identifizierbar.This is achieved by the components being wired and controlled in a star-shaped manner in the bus system, with a separate wiring harness leading from each distribution point to each component. The component connected to the wiring harness is assigned a corresponding address. As a result, the component connected to this wiring harness can later be uniquely identified.
Auf diese Weise muss bei der Installation einer Regeleinrichtung für eine vorgegebene Komponente vor deren Anschluss an das Regelgerät keine Adresse an der Komponente selbst eingestellt werden, wodurch die Installation vereinfacht wird. Beim Austausch eines defekten Fühlers kann einfach ein neuer Fühler an die gleiche Buchse angeschlossen werden, sodass das System sofort wieder einsatzfähig ist, ohne dass an dem neu hinzugekommenen Fühler eine Adresse eingestellt werden muss. Auch kann der Austausch von Fühlern an der Anlage in einfacher Weise vorgenommen werden.In this way, when installing a controller for a given component prior to its connection to the controller, no address needs to be set on the component itself, thereby simplifying the installation. When replacing a faulty sensor, a new sensor can simply be connected to the same socket so that the system can be used immediately without having to set an address on the newly added sensor. Also, the exchange of sensors on the system can be made in a simple manner.
Die Erfindung wird beispielsweise anhand der Zeichnung näher erläutert. Es zeigen.The invention will be explained in more detail for example with reference to the drawing. Show it.

Die beschriebene Art der Adresszuteilung erfolgt vorzugsweise bei jeder Aktivierung bzw. beim Einschalten des Bus-Systems selbsttätig. Dabei wird vom Bus-System ausgehend die Adresszuteilung vorgenommen, während bei der Anordnung nach
Wenn ein defekter Fühler, z. B. der Fühler
Wenn z. B. die Fühler
Damit entfallen die Nachteile des bekannten CAN-Bus-Systems, bei dem an den einzelnen Komponenten selbst jeweils eine Adresseinstellung vorgenommen werden muss, für die Erstinbetriebnahme sowie wenn Änderung an der Bahnlaufregeleinrichtung vorgenommen werden sollen.This eliminates the disadvantages of the known CAN bus system, in which an address setting must be made on the individual components themselves, for initial commissioning and if change to the web guiding device to be made.
Nach der automatischen Adressvergabe verhält sich das System wie ein normales CAN-Bus-System. Die Funktionalität des CAN-Bus-Systems wird durch das beschriebene Verfahren in keiner Weise beeinträchtigt.After automatic address assignment, the system behaves like a normal CAN bus system. The functionality of the CAN bus system is in no way impaired by the described method.
Die beschriebene Schaltung kann auch bei anderen Bus-Systemen verwendet werden und sie ist nicht auf ein CAN-Bus-System beschränkt. Auch ist die Adressvergabe nicht auf die beschriebenen drei Teilnehmer begrenzt, vielmehr kann eine größere Anzahl von Teilnehmern an das Bus-System sternförmig angeschlossen werden.The circuit described can also be used in other bus systems and is not limited to a CAN bus system. The address allocation is not limited to the described three participants, but a larger number of participants to the bus system can be connected in a star shape.
Durch die erfindungsgemäße sternförmige Verteilung der Komponenten am Verteiler
