Abstract

ROM memory has memory read and written to via connection pins and is also operated via integrated contactless RF interface. Contactless RF interface allows query and change to data e.g. device and repair parameters, last service date, results, fitter, error codes, settings parameters. Device itself reads ROM data via connection pins. Unauthorized access is prevented by pass words or challenge and response procedure.

Description

ProblemstellungProblem

Viele elektrische Geräte und Steuerungen unterliegen zyklischen Inspektionsintervallen, die aus Belangen der Geräte- und Anlagensicherheit oder vorbeugender Instandhaltung vorgegeben werden. Immer öfter gibt es Vorgaben, das Datum und Details der ausgeführten Inspektionen am und im Gerät zu dokumentieren. Teilweise müssen im Rahmen der Überprüfungen auch neue Funktionsparameter oder Anpassungen eingegeben, sowie Fehlerspeicher gelesen und gelöscht werden.Many electrical devices and controls are subject to cyclical inspection intervals that occur Device and system safety or preventive maintenance are specified. There are more and more specifications, the date and details of the inspections carried out on and in the device to document. In some cases, new functional parameters must also be included in the checks or adjustments are entered, and error memories are read and deleted.

Zum Anschluss von speziellen Wartungsgeräten, Diagnosewerkzeugen oder tragbaren Computern werden entweder innerhalb der Geräte Verbindungsmöglichkeiten, oder von außen zugängliche Steckverbindungen vorgesehen. Diese müssen aber zum Teil hohen Anforderungen bezüglich Manipulationssicherheit, Feuchtigkeitsschutz oder Vandalismus genügen. Auch die Gehäuse­ konstruktionen und -montagen werden durch den Einbau solcher Steckverbindungen erschwert.For connecting special maintenance devices, diagnostic tools or portable computers connectivity options are available either within the devices or externally Plug connections provided. However, some of these have to meet high requirements Tamper-proof, moisture protection or vandalism are sufficient. The housings too constructions and assemblies are made more difficult by the installation of such plug connections.

Innenliegende Steckverbindungen bedeuten Zeitaufwand für das Öffnen der Geräte und bergen weiteres Fehlerpotential. Weiterhin können heute entsprechende Parameter nur dann gelesen und geschrieben werden, wenn das elektrische Gerät oder Teile des elektrischen Gerätes mit Spannung versorgt werden. Dies ist im Rahmen der Produktion (Programmieren von Fertigungsparametern) oder Lagerhaltung oder aufgrund von Fehlerfällen nicht immer möglich. Ebenso lassen sich viele Geräte je nach Einsatzzweck nicht mit dauerhaften äußerlichen Kennzeichnungen versehen oder sind äußerlich nicht zu unterscheiden.Internal plug connections mean that the devices have to be opened and hidden further potential for errors. Corresponding parameters can only be read and read today be written when the electrical device or parts of the electrical device are live be supplied. This is in the context of production (programming of manufacturing parameters) or Warehousing or not always possible due to errors. Likewise, many devices can ever not provided with permanent external markings according to the intended use or are external indistinguishable.

AbhilfemaßnahmeRemedial action

Ein neuer nichtflüchtiger Speicher, dessen Speicherbereiche über die Anschluss-Pins beschrieben und gelesen werden, die aber ebenfalls überein integriertes kontaktloses RF-Interface bedient werden können, ermöglicht sämtliche Daten, wie z. B. Geräte- und Fertigungsparameter, letztes Wartungsdatum, Ergebnisse, Monteur, Fehlercodes, Einstellungsparameter etc. kontaktlos über das RF-Interface abzufragen, bzw. auch zu ändern. Das Gerät selber kann die entsprechenden Daten kontaktbehaftet über die Anschluss-Pins aus dem nichtflüchtigen Speicher auslesen bzw. in diesen hineinspeichern. Damit Nicht-autorisierte Personen auf die Daten speziell über das RF-Interface nicht zugreifen können, lassen sich einzelne Speicherbereiche oder der gesamte Speicher vor dem Zugriff durch Passworte oder einen Autorisierungsvorgang (Challenge und Response Verfahren) schützen.A new non-volatile memory, the memory areas of which are described via the connection pins and read, but which is also operated via an integrated contactless RF interface can be, all data such. B. device and manufacturing parameters, last Maintenance date, results, fitter, error codes, setting parameters etc. contactless via the Query or change the RF interface. The device itself can do the relevant data Read out from or into the non-volatile memory via the connection pins save it. This prevents unauthorized persons from accessing the data specifically via the RF interface can access individual memory areas or the entire memory before access protect with passwords or an authorization process (challenge and response procedure).
