Description

Ein/Ausgabe-Einheit An I / O unit
Die Erfindung betrifft eine Ein/Ausgabe-Einheit eines steuerungstechnischen bzw. regelungstechnischen Systems, insbesondere eines Prozessleitsystems oder eines Gebäudemanagementsystems, nach dem Oberbegriff des Anspruchs 1.The invention relates to an input / output unit of a control engineering or control engineering system, in particular a process control system or a building management system, according to the preamble of claim 1.
Aus der Praxis bekannte Ein/Ausgabe-Einheiten eines steuerungstechnischen bzw. regelungstechnischen Systems verfügen über eine Vielzahl von Span- nungsanschlüssen, an die insbesondere Sensoren, die als Messsignal ein Spannungssignal bereitstellen, angeschlossen werden können. Derartige Ein/Ausgabe-Einheiten mit Spannungsanschlüssen sind besonders kostengünstig. An solche Ein/Ausgabe-Einheiten mit Spannungsanschlüssen können keine Sensoren angeschlossen werden, die als Messsignal ein Stromsignal be- reitstellen. Häufig ist es jedoch aus Genauigkeitsgründen wünschenswert, als Sensoren solche Sensoren zu verwenden, die als Messsignal ein Stromsignal bereitstellen, da derartige Sensoren, die als Messsignal ein Stromsignal bereitstellen, gegenüber elektromagnetischen Interferenzen unempfindlicher sind als Sensoren, die als Messsignal ein Spannungssignal bereitstellen. Solche elekt- romagnetischen Interferenzen können dann auftreten, wenn in der Nähe der Sensoren Lasten zugeschaltet oder abgeschaltet werden. Ein weiterer Vorteil von Sensoren, die als Messsignal ein Stromsignal bereitstellen, gegenüber Sensoren, die als Messsignal ein Spannungssignal bereitstellen, besteht darin, dass dieselben auch mit großer Distanz zur Ein/Ausgabe-Einheit positioniert werden können, da eine große Verdrahtungslänge und damit ein großer Verdrahtungswiderstand die Genauigkeit des Messsignals nicht beeinflusst. Sollen jedoch Sensoren, die als Messsignal ein Stromsignal bereitstellen, in ein steuerungstechnisches bzw. regelungstechnisches System eingebunden werden, so müssen für dieselben separate Ein/Ausgabe-Einheiten bereitgehalten werden. Dies ist aus Kostengründen von Nachteil. Es besteht daher Bedarf an einer preiswerten Ein/Ausgabe-Einheit, an die einerseits Sensoren, die als Messsignal ein Spannungssignal bereitstellen, und andererseits Sensoren, die als Messsignal ein Stromsignal bereitstellen, angeschlossen werden können.Input / output units of a control technology or control technology system known from practice have a multiplicity of voltage connections, to which, in particular, sensors which provide a voltage signal as the measurement signal can be connected. Such input / output units with voltage connections are particularly cost-effective. Such sensors can not be connected to such input / output units with voltage connections, which provide a current signal as a measuring signal. However, it is often desirable for reasons of precision to use as sensors such sensors which provide a current signal as a measuring signal, since such sensors, which provide a current signal as a measuring signal, are less sensitive to electromagnetic interference than sensors which provide a voltage signal as a measuring signal. Such electromagnetic interference can occur when loads are turned on or off near the sensors. Another advantage of sensors that provide a current signal as a measuring signal, as compared to sensors that provide a voltage signal as a measuring signal, is that they can be positioned at a great distance to the input / output unit, as a large wiring length and thus a large Wiring resistance does not affect the accuracy of the measurement signal. However, if sensors, which provide a current signal as a measurement signal, are to be integrated into a control-technical or control-technical system, separate input / output units must be kept ready for them. This is disadvantageous for cost reasons. There is therefore a need for a low-cost input / output unit to which sensors which provide a voltage signal as a measurement signal and sensors which provide a current signal as a measurement signal can be connected to one another.

Diese Aufgabe wird durch eine Ein/Ausgabe-Einheit mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by an input / output unit having the features of claim 1.
Die erfindungsgemäße Ein/Ausgabe-Einheit weist ein Adaptermodul mit Stromanschlüssen auf, wobei an die Stromanschlüsse des Adaptermoduls mindestens ein Sensor, der als Messsignal ein Stromssignal bereitstellt, anschließbar ist, und wobei die Stromanschlüsse des Adaptermoduls mit Spannungsanschlüssen des Basismoduls kontaktierbar sind.The input / output unit according to the invention has an adapter module with power connections, wherein at least one sensor that provides a current signal as a measurement signal can be connected to the power connections of the adapter module, and wherein the power connections of the adapter module can be contacted with voltage connections of the base module.
Die hier vorliegende Erfindung beruht auf der Idee, eine Ein/Ausgabe-Einheit eines steuerungstechnischen bzw. regelungstechnischen Systems, an die sowohl Sensoren, die als Messsignal ein Spannungssignal bereitstellen, als auch Sensoren, die als Messsignal ein Stromsignal bereitstellen, angeschlossen werden können, dadurch bereitzustellen, dass ein konventionelles Basismodul mit Spannungsanschlüssen durch ein Adaptermodul mit Stromanschlüssen im Bedarfsfall erweitert wird, wobei an die Stromanschlüsse des Adaptermoduls mindestens ein Sensor, der als Messsignal ein Stromsignal bereitstellt, anschließbar ist, und wobei die Stromanschlüsse des Adaptermoduls mit den Spannungsanschlüssen das Basismoduls kontaktierbar sind, um so die Funktionalität des Basismoduls zu erweitern. Hierdurch kann eine konventionelle Ein/Ausgabe-Einheit mit Spannungsanschlüssen einfach und kostengünstig in eine erfindungsgemäße Ein/Ausgabe- Einheit umkonfiguriert werden, die dann auch über Stromanschlüsse verfügt, um so auch Sensoren, die als Messsignal ein Stromsignal bereitstellen, an die erfindungsgemäße Ein/Ausgabe-Einheit anzuschließen.The present invention is based on the idea of an input / output unit of a control engineering or control system to which both sensors that provide a voltage signal as a measurement signal, as well as sensors that provide a current signal as a measurement signal can be connected, characterized provide that a conventional base module with voltage terminals is extended by an adapter module with power connections if necessary, wherein at least one sensor that provides a current signal as a measurement signal can be connected to the power terminals of the adapter module, and wherein the power terminals of the adapter module with the voltage terminals contactable the base module are to extend the functionality of the base module. In this way, a conventional input / output unit with voltage connections can be easily and inexpensively reconfigured into an input / output unit according to the invention, which then also has power connections, including sensors which provide a current signal as a measurement signal to the input / output according to the invention Unit.

Hereinafter, embodiments of the invention, without being limited thereto, explained in more detail with reference to the drawing. In the drawing shows:

Das in Fig. 1 gezeigte Ausführungsbeispiel der erfindungsgemäßen Ein/Ausgabe-Einheit 10 verfügt über ein Basismodul 11 und ein Adaptermodul 12, wobei das Adaptermodul 12 im Sinne der Pfeile 13 auf das Basismodul 11 aufgesteckt werden kann.The exemplary embodiment of the input / output unit 10 shown in FIG. 1 has a base module 11 and an adapter module 12, wherein the adapter module 12 can be plugged onto the base module 11 in the direction of the arrows 13.
Das Basismodul 11 der erfindungsgemäßen Ein/Ausgabe-Einheit 10 verfügt über eine Vielzahl von Spannungsanschlüssen 14, an die Sensoren, die als Messsignal ein Spannungssignal bereitstellen, anschließbar sind. Das Adaptermodul 12 verfügt über eine Vielzahl von Stromanschlüssen 15, an die mindestens ein Sensor, der als Messsignal ein Stromsignal bereitstellt, angeschlossen werden kann.The base module 11 of the input / output unit 10 according to the invention has a multiplicity of voltage terminals 14, to which sensors which provide a voltage signal as a measuring signal can be connected. The adapter module 12 has a plurality of power connections 15, to which at least one sensor which provides a current signal as a measurement signal can be connected.
Die Stromanschlüsse 15 des Adaptermoduls 12 sind mit den Spannungsanschlüssen 14 des Basismoduls 11 kontaktierbar, um so unter Verwendung des Adaptermoduls 12 auch Sensoren, die als Messsignal ein Stromsignal bereitstellen, an das Basismodul 11 anzuschließen. Durch das Adaptermodul 12 kann demnach ein Basismodul 11 , welches eigentlich nur über Spannungsan- Schlüsse zum Anschließen von Sensoren, die als Messsignal ein Spannungssignal bereitstellen, verfügt, dahingehend erweitert werden kann, dass auch Sensoren, die als Messsignal ein Stromsignal bereitstellen, an dasselbe angeschlossen werden können, nämlich über das Adaptermodul 12.The power connections 15 of the adapter module 12 can be contacted with the voltage connections 14 of the base module 11 so as to connect to the base module 11 using the adapter module 12 also sensors which provide a current signal as a measurement signal. Accordingly, a base module 11, which actually only has voltage connections for connecting sensors which provide a voltage signal as a measurement signal, can be extended by the adapter module 12 to the effect that sensors which provide a current signal as a measurement signal are also connected to the same can be, namely on the adapter module 12th
Fig. 2 zeigt Details einer ein Basismodul 11 und ein Adaptermodul 12 umfassenden erfindungsgemäßen Ein/Ausgabe-Einheit 10 im Sinne eines Verdrahtungsschemas für den Anschluss von Sensoren, die als Messsignal ein Stromsignal bereitstellen, an die erfindungsgemäße Ein/Ausgabe-Einheit 10.2 shows details of a input / output unit 10 according to the invention comprising a base module 11 and an adapter module 12 in the sense of a wiring diagram for the connection of sensors, which provide a current signal as a measurement signal, to the input / output unit 10 according to the invention.
Wie Fig. 2 entnommen werden kann, sind jeweils zwei Stromanschlüsse 15 des Adaptermoduls 12, nämlich gemäß Fig. 2 die Stromanschlüsse "A1" und "B1", "A2" und "B2" sowie "A3" und "B3", über jeweils einen elektrischen Widerstand 17 und einen Masseanschluss "G" des Adaptermoduls 12 gemeinsam mit einem ersten Masseanschluss "Signal Ground Y" des Basismoduls 11 kontaktiert.As can be seen from FIG. 2, two power connections 15 of the adapter module 12, namely the power connections "A1" and "B1", "A2" and "B2" as well as "A3" and "B3", respectively, are shown in FIG an electrical resistance 17 and a ground terminal "G" of the adapter module 12 together with a first ground terminal "Signal Ground Y" of the base module 11 contacted.
Ein erster Sensor 16, der als Messsignal ein Stromsignal bereitstellt, ist mit einem ersten Anschluss an einen ersten Stromanschluss "A1" des Stromanschlusspaars "A1/B1" des Adaptermoduls 12 angeschlossen, wobei der zweite Stromanschluss "B1" dieses Stromschlusspaars "A1/B1" des Adaptermoduls 12 mit einem Spannungsanschluss "Universal Input 1" des Basismoduls 11 kontaktiert ist. Mit einem zweiten Anschluss ist der erste Sensor 16, der als Messsignal ein Stromsignal bereitstellt, an einen zweiten Masseanschluss "Signal Ground 1" des Basismoduls 11 angeschlossen.A first sensor 16, which provides a current signal as the measurement signal, is connected with a first connection to a first power connection "A1" of the power connection pair "A1 / B1" of the adapter module 12, wherein the second power connection "B1" of this power connection pair "A1 / B1" of the adapter module 12 is contacted with a voltage connection "Universal Input 1" of the base module 11. With a second connection, the first sensor 16, which provides a current signal as a measurement signal, is connected to a second ground connection "Signal Ground 1" of the base module 11.
Auf die obige Art und Weise kann an das Basismodul 11 , welches als Anschlüsse lediglich Spannungsanschlüsse aufweist, unter Verwendung des Adaptermoduls 12, welches als Anschlüsse Stromanschlüsse bereitstellt, auch ein Sensor 16 angeschlossen werden, der als Messsignal ein Stromsignal bereitstellt.In the above manner, a sensor 16, which provides a current signal as a measurement signal, can be connected to the base module 11, which has only voltage connections as terminals, using the adapter module 12, which provides power connections as terminals.
Gemäß Fig. 2 sind neben dem ersten Sensor 16 weitere Sensoren 16' und 16", die als Messsignal jeweils ein Stromsignal bereitstellen, unter Verwendung des Adaptermoduls 12 an das Basismodul 11 angeschlossen. So ist der Sensor 16' über seinen ersten Anschluss an den ersten Stromanschluss "A2" des Strom- anschlusspaars "A2/B2" angeschlossen und der Sensor 16" ist über seinen ersten Anschluss an den ersten Stromschluss "A3" des Stromanschlusspaars "A3/B3" des Adaptermoduls 12 kontaktiert. Die zweiten Stromanschlüsse "B2", "B3" dieser Stromanschlusspaare "A2/B2", "A3/B3" des Adaptermoduls 12 sind jeweils mit einem Spannungsanschluss "Universal Input 2", "Universal Input 3" des Basismoduls 11 kontaktiert. Jedem dieser Stromanschlusspaare "A2/B2" und "A3/B3" ist wiederum ein elektrischer Widerstand 17 zugeordnet, über den die Stromanschlüsse des jeweiligen Stromanschlusspaars jeweils gemeinsam an den Masseanschluss "G" des Adaptermoduls 12 angeschlossen sind, um so dieselben gemeinsam an den ersten Masseanschluss "Signal Ground Y" des Basismoduls 11 zu kontaktieren. Die zweiten Anschlüsse der Sensoren 16' und 16" sind jeweils an zweite Masseanschlüsse "Signal Ground 2" und "Signal Ground 3" des Basismoduls 11 angeschlossen.2, in addition to the first sensor 16, further sensors 16 'and 16 ", which each provide a current signal as the measurement signal, are connected to the base module 11 using the adapter module 12.

Each of these power connection pairs "A2 / B2" and "A3 / B3" is in turn assigned an electrical resistance 17, via which the power connections of the respective power connection pair are connected together to the ground terminal "G" of the adapter module 12, so that they are common to the first Ground connection "Signal Ground Y" of the base module 11 to contact. The second terminals of the sensors 16 'and 16 "are respectively connected to second ground terminals" Signal Ground 2 "and" Signal Ground 3 "of the base module 11.
