Abstract
Description
Die Erfindung betrifft ein Verfahren zur automatischen Sensorerkennung durch einen Prozeßregler.The The invention relates to a method for automatic sensor detection by a process controller.
Bei bekannten Plug-and-play Lösungen z. B. über eine USB Schnittstelle eines PCs findet eine Kommunikation zwischen den beteiligten Geräten allein in Form von ausgetauschten Daten statt.at known plug-and-play solutions z. B. over a USB interface of a PC finds a communication between the participating devices solely in the form of exchanged data.
An industrieübliche Prozeßregler können über Sensoreingänge mehrere verschiedene Sensortypen angeschlossen werden, die unterschiedliche Signale liefern. Beispielsweise können Wegsensoren ein Normsignal als Strom im Bereich von 4–20 mA abgeben, Durchflußsensoren eine Frequenz eines Wechselspannungssignals oder Temperatursensoren eine Spannung.At industry standard process controller can several via sensor inputs different sensor types are connected, the different ones Deliver signals. For example, displacement sensors can be a standard signal as current in the range of 4-20 mA release, flow sensors a frequency of an AC signal or temperature sensors a tension.
Gemäß dem Stand der Technik sind in Prozeßreglern mehrere Auswerteschaltungen für mögliche anschließbare Sensoren integriert, wovon die jeweils benötigte vom Anwender manuell über ein Bedienmenü ausgewählt werden muß. Dem Anwender muß aber bekannt sein, daß der Eingang des Prozeßreglers passend zu seinem Sensor konfiguriert werden muß. Im ungünstigsten Fall konnte bisher eine Auswerteschaltung sogar durch ein falsches Sensorsignal zerstört werden.According to the state The technology is in process controllers several evaluation circuits for possible connectable Sensors are integrated, of which the required by the user manually via a Operating menu are selected got to. the But user must be known that the Input of the process controller must be configured to match his sensor. In the worst case could so far one Evaluation circuit even be destroyed by a wrong sensor signal.
Deshalb ist es Ziel der Erfindung ein Verfahren zur Verfügung zu stellen, das es ermöglicht an einen Prozeßregler angeschlossene Sensoren automatisch zu erkennen und die erkannte Konfiguration zu speichern.Therefore It is the object of the invention to provide a method which makes it possible a process controller Automatically detect connected sensors and the detected Save configuration.
Im erfindungsgemäßen Verfahren, das in den beigefügten Patentansprüchen angegeben ist, werden zunächst physikalische Werte gemessen, die dann ausgewertet und das Ergebnis als Konfiguration gespeichert wird. Die Erfindung schafft somit ein Verfahren, das es ermöglicht in einem System vorhandene Sensoren automatisch mittels mehrerer Sensorauswerteschaltungen eines Prozeßreglers zu erkennen und die erkannte Konfiguration zu speichern.in the inventive method, that in the attached claims is stated, first measured physical values, which then evaluated and the result is saved as a configuration. The invention thus provides a method that makes it possible in a system existing sensors automatically by means of several Sensorauswerteschaltungen a process controller to recognize and save the recognized configuration.
Der Sensoreingang wird mittels verschiedener Auswerteschaltungen in einer definierten Reihenfolge abgeprüft auf ausgegebene Meßsignale. So wird z. B. zunächst ermittelt, ob vom Sensor ein Strom ausgegeben wird. Ist ein Strom meßbar, so wird diesem ein Sensortyp zugeordnet. Die entsprechende Konfiguration wird im Datenspeicher des Prozeßreglers hinterlegt.Of the Sensor input is by means of various evaluation circuits in a defined sequence checked for output measuring signals. So z. B. first determines whether a current is being output by the sensor. Is a stream measurable, so a sensor type is assigned to this. The corresponding configuration is stored in the data memory of the process controller deposited.
War kein Strom erfaßbar, wird anschließend abgefragt, ob z. B. ein Frequenzsignal zu finden ist.was no current detectable, is then queried, whether z. B. a frequency signal can be found.
Dieser Scanvorgang, das Abprüfen des Sensortyps, wird nach Anlegen der Betriebsspannung automatisch gestartet. Falls ein Meßsignal gefunden wird, so wird dieses im Display angezeigt. Nach Bestätigung des Anwenders wird die entsprechende Konfiguration im Datenspeicher des Prozeßreglers hinterlegt.This Scanning, the checking of the sensor type, becomes automatic after application of the operating voltage started. If a measurement signal is found, it will be shown on the display. After confirmation of the User is the corresponding configuration in the data memory deposited by the process controller.
Eine Ausführungsform der Erfindung wird nun unter Bezugnahme auf die beigefügte Zeichnung näher beschrieben.A embodiment The invention will now be described with reference to the accompanying drawings.
Die einzige Figur der Zeichnung ist ein schematisches Blockschaltbild eines Prozeßreglers mit angeschlossenem Sensor.The single figure of the drawing is a schematic block diagram a process controller with connected sensor.
