Description

Die Erfindung betrifft eine Druckluftwartungsvorrichtung bestehend aus mehreren aneinander reihbaren Funktionsmodulen.The invention relates to a compressed air maintenance device consisting of several mutually reihbare function modules.

Bei einer derartigen, aus der DE 19746179 C2 bekannten Druckluftwartungsvorrichtung sind die einzelnen Funktionsmodule mechanisch miteinander verbunden, wobei die Druckluft direkt von Modul zu Modul über die aneinander liegenden Begrenzungsflächen geleitet wird und die elektrische Verbindung über eine in einer Halteschiene für die einzelnen Module integrierten Busleiste erfolgt. Solche Funktionsmodule bzw. Wartungsmodule zur Druckluftaufbereitung sind beispielsweise Einschaltventile, Druckregler, Filter, Filterregler, Durchflussmesser, Verteiler, Adapter, Steuermodule, Überwachungsmodule und dergleichen. Jedes dieser Module ist in bekannter Weise individuell ausgestaltet, wobei im Hinblick auf sehr unterschiedliche Kundenwünsche eine Vielzahl von unterschiedlich konfigurierten Ausführungen bereitzustellen sind. Allein im Hinblick auf die Vielzahl von Möglichkeiten der elektrischen Kommunikation und Busvarianten müssen viele verschiedene Ausführungen konstruiert, hergestellt und gelagert werden.In such, from the DE 19746179 C2 known compressed air maintenance device, the individual functional modules are mechanically interconnected, wherein the compressed air is passed directly from module to module on the adjacent boundary surfaces and the electrical connection via a bus bar integrated in a support rail for the individual modules. Such functional modules or maintenance modules for compressed air preparation are, for example, on-off valves, pressure regulators, filters, filter regulators, flow meters, distributors, adapters, control modules, monitoring modules and the like. Each of these modules is configured individually in a known manner, with a large number of differently configured designs being provided with regard to very different customer requirements. Alone with regard to the variety of possibilities of electrical communication and bus variants many different designs must be designed, manufactured and stored.

Eine Aufgabe der vorliegenden Erfindung besteht darin, die einzelnen Funktionsmodule bei einer geringeren Zahl von Grundvarianten variabler einsetzen zu können.An object of the present invention is to be able to use the individual functional modules with a smaller number of basic variants variable.

Diese Aufgabe wird erfindungsgemäß durch eine Druckluftwartungsvorrichtung mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a compressed air maintenance device with the features of claim 1.

Die Vorteile der Erfindung bestehen insbesondere darin, dass sich durch Kombination der einheitlichen Pneumatikbasisblöcke mit variablen Peripherieblöcken eine Vielzahl unterschiedlicher Funktionsmodule zusammenstellen lassen. Die Mehrfachverwendbarkeit der Funktionsblöcke in Verbindung mit Pneumatikbasisblöcken führt zu einer Optimierung der Entwicklungs- und Logikkosten. Vor Ort können beispielsweise Funktionsblöcke ausgetauscht oder Pneumatikbasisblöcke durch Funktionsblöcke ergänzt werden, so dass vor Ort eine Anpassung an die jeweilige Einsatzumgebung vorgenommen werden kann. Mit relativ wenigen unterschiedlichen Grundvarianten von Funktionsblöcken lassen sich einheitliche Pneumatikbasisblöcke zu sehr unterschiedlichen Ausführungen von Funktionsmodulen konfigurieren.The advantages of the invention are, in particular, that a large number of different functional modules can be assembled by combining the uniform pneumatic base blocks with variable peripheral blocks. The reusability of the functional blocks in conjunction with basic pneumatic blocks leads to an optimization of the development and logic costs. For example, functional blocks can be exchanged on site or pneumatic blocks can be supplemented with functional blocks so that an adaptation to the respective operating environment can be carried out on site. With relatively few different basic variants of function blocks, uniform pneumatic basic blocks can be configured into very different versions of function modules.

In vorteilhafter Weise ist einer der Funktionsblöcke als elektrischer Verkettungsblock ausgebildet und dient zur elektrischen Längsverkettung mehrerer Funktionsmodule. Dieser Verkettungsblock kann je nach der vom Kunden oder Anwender gewünschten Verkettung ausgebildet werden und enthält entweder Einzelleitungen oder ein vom Anwender gewünschtes Feldbussystem.Advantageously, one of the functional blocks is designed as an electrical interlinking block and serves for the electrical longitudinal linking of a plurality of functional modules. This interlinking block can be designed according to the chaining desired by the customer or user and contains either individual lines or a fieldbus system desired by the user.

Weiterhin enthält der Verkettungsblock in einer Ausgestaltung der Erfindung elektronische Steuer- und Diagnosemittel und Visualisierungsmittel für Prozessparameter und -abläufe und kann auch mit einer Feldbusschnittstelle versehen sein. Die Steuer- und Diagnosemittel können Funktionen für die gesamte Druckluftwartungsvorrichtung oder nur für einen oder mehrere Funktionsmodule enthalten.Furthermore, in one embodiment of the invention, the interlinking block contains electronic control and diagnostic means and visualization means for process parameters and processes and can also be provided with a fieldbus interface. The control and diagnostic means may include functions for the entire compressed air maintenance device or only for one or more functional modules.

Der Verkettungsblock besitzt zweckmäßigerweise an wenigstens einer nicht am Pneumatikbasisblock anliegenden Seite eine elektrische Schnittstelle zur elektrischen Verbindung mit einem am Pneumatikbasisblock anliegenden Funktionsblock, wobei die Schnittstelle insbesondere als elektrischer Stecker oder elektrische Steckaufnahme ausgebildet ist. Beim Anbringen eines solchen Funktionsblocks werden dann gleichzeitig die pneumatischen Verbindungen zum Pneumatikbasisblock und die elektrischen Verbindungen zum Verkettungsblock hergestellt. Dabei ist es zweckmäßig, dass der wenigstens eine Funktionsblock den Pneumatikbasisblock und den Verkettungsblock übergreift.The interlinking block expediently has on at least one side which is not in contact with the pneumatic base block an electrical interface for the electrical connection to a functional block resting against the pneumatic base block, wherein the interface is designed in particular as an electrical plug or electrical plug-in receptacle. When attaching such a function block, the pneumatic connections to the pneumatic base block and the electrical connections to the interlinking block are then simultaneously produced. It is expedient that the at least one functional block overlaps the pneumatic base block and the interlinking block.

Vorteilhafterweise ist auch ein an der vom Verkettungsblock abgewandten Frontseite des Pneumatikbasisblocks anbringbarer Frontblock vorgesehen, der über dem Pneumatikbasisblock oder einem damit verbundenen Funktionsblock mit dem Verkettungsblock elektrisch verbunden ist. Der Frontblock ist dabei bevorzugt mit einer Displayvorrichtung und/oder Bedienungselementen versehen.Advantageously, a front block which can be attached to the front side of the pneumatic base block facing away from the interlinking block is also provided, which is electrically connected to the interlinking block via the pneumatic base block or a functional block connected thereto. The front block is preferably provided with a display device and / or controls.

Der Verkettungsblock besitzt in vorteilhafter Weise elektrische und/oder mechanische Decodierungsmittel zur Erkennung der jeweils angeschlossenen Funktionsblöcke.The interlinking block advantageously has electrical and / or mechanical decoding means for detecting the respectively connected functional blocks.

Der Verkettungsblock kann einteilig ausgebildet sein oder aus einem Leitungsführungselement sowie einem daran elektrisch ankoppelbaren Elektronikblock bestehen. Das Leitungsführungselement bildet dabei zusammen mit Leitungsführungselementen der anderen Funktionsmodule einen sich entlang der Druckluftwartungsvorrichtung erstreckenden Leitungsstrang, an denen die Elektronikblöcke anbringbar, beispielsweise ansteckbar oder anklemmbar sind.The interlinking block may be formed in one piece or consist of a line guide element and an electronic block which can be electrically coupled thereto. The line guide element forms, together with line guide elements of the other functional modules, a line of cables extending along the compressed air maintenance device, to which the electronics blocks can be attached, for example, connected or clamped.

Der Verkettungsblock besitzt vorzugsweise wenigstens eine Leiterplatte, die mit Leiterplatten in darin ankoppelbaren Funktionsblöcken elektrisch verbindbar, insbesondere zusammensteckbar ist.The interlinking block preferably has at least one printed circuit board which is electrically connectable, in particular can be plugged together, with printed circuit boards in function blocks which can be coupled thereto.

Das in den Figuren 1 und 3 dargestellte Funktionsmodul ist mit anderen Funktionsmodulen aneinander reihbar, wobei die Summe der aneinander gereihten Funktionsmodule eine Druckluftwartungsvorrichtung bildet, wie dies im eingangs angegebenen Stand der Technik dargestellt und beschrieben ist. Das hier als Ausführungsbeispiel dargestellte Funktionsmodul ist baukastenartig aufgebaut. Es besteht aus einem Pneumatikbasisblock 10, wobei die Pneumatikbasisblöcke aller Funktionsmodule zumindest bezüglich der Basisschnittstellen gleich aufgebaut sind. Für die beiden endseitigen Funktionsmodule können geringfügige Modifikationen vorgesehen sein. Der Pneumatikbasisblock 10 besitzt an seinem nach entgegengesetzten Seiten weisenden parallelen Stirnseiten 11 Pneumatikschnittstellen 12, um eine durchgehende Pneumatikverbindung durch alle aneinander gereihten Funktionsmodule bzw. Pneumatikbasisblöcke 10 zu gewährleisten. Zur mechanischen bzw. dichtenden Verbindung können Steck-, Rast- oder Schraubverbindungsmittel vorgesehen sein, die zur Vereinfachung nicht dargestellt sind.That in the FIGS. 1 and 3 illustrated functional module is connected to other functional modules together, wherein the sum of the juxtaposed functional modules forms a compressed air maintenance device, as shown and described in the prior art mentioned above. The functional module shown here as an exemplary embodiment is constructed like a box. It consists of a basic pneumatic block 10, wherein the basic pneumatic blocks of all functional modules are constructed the same, at least with regard to the basic interfaces. For the two end functional modules minor modifications may be provided. The pneumatic base block 10 has at its pointing to opposite sides parallel end faces 11 pneumatic interfaces 12 to ensure a continuous pneumatic connection through all juxtaposed functional modules or Pneumatikbasisblöcke 10. For mechanical or sealing connection plug-in, locking or screw connection means may be provided, which are not shown for simplicity.

An den vier übrigen Seitenwandungen des Pneumatikbasisblocks 10 sind Funktionsblöcke angeordnet, die variabel anbringbar sind, wobei die Zahl anwendungsorientiert variieren kann. An der Vorderseite ist ein Frontblock 13 angeordnet, der mit einem Display 14 und als Tasten ausgebildeten Bedienungselementen 15 versehen ist. Ein solcher Frontblock 13 braucht nur an einem der Funktionsmodule angeordnet sein, wobei die Bedienung und die Anzeige für alle Funktionsmodule ausgebildet sein kann.On the four remaining side walls of the pneumatic base block 10 functional blocks are arranged, which are variably attachable, the number can vary application-oriented. At the front of a front block 13 is arranged, which is provided with a display 14 and as buttons formed controls 15 is provided. Such a front block 13 need only be arranged on one of the functional modules, wherein the operation and the display can be designed for all functional modules.

An der entgegengesetzten Rückseite ist ein Verkettungsblock 16 angeordnet, der zur elektrischen Verkettung der Funktionsmodule dient. Er besitzt an seinen zu den Stirnseiten 11 des Pneumatikbasisblocks 10 parallelen Seitenwandungen elektrische Steckverbindungselemente 17, die zum Zusammenstecken mit entsprechenden Verkettungsblöcken 16 der anderen Funktionsmodule dienen. Hierdurch wird ein durchgehendes Leitungssystem gebildet, das die Funktionsmodule elektrisch miteinander verbindet. Es kann sich dabei um Feldbusleitungen und/oder parallele Leitungen handeln, wobei auch die Stromversorgung, falls erforderlich, der verschiedenen Funktionsmodule der Druckluftwartungsvorrichtung über diese Leitungen erfolgen kann. Die Verkettungsblöcke 16 sind an einer Halteschiene 18 angeordnet, die zum Halten der gesamten Druckluftwartungsvorrichtung dient. Alternativ oder zusätzlich können die Funktionsmodule bzw. Pneumatikbasisblöcke auch direkt miteinander verkettet sein, z.B. durch Klemm-, Rast- oder Schraubmittel. Im Falle von Feldbusleitungen enthält der Verkettungsblock 16 eine entsprechende Busstation. Die elektronischen Elemente des Verkettungsblocks 16 sind auf einer Leiterplatte 19 angeordnet, wobei bei Erfordernis auch mehrere Leiterplatten vorgesehen sein können. Die Leiterplatte 19 kann elektronische Steuer- und/oder Diagnosemittel und/oder Visualisierungsmittel zur Visualisierung von Prozessparametern und/oder - abläufen enthalten, die zur Steuerung und zur Diagnose des eigenen Funktionsmoduls oder aller Funktionsmodule dienen kann. Die Steuer- und/oder Diagnosemittel brauchen daher nicht in jedem Verkettungsblock 16 angeordnet sein. Die Steuer- und/oder Diagnosemittel können beispielsweise als Mikrocontroller ausgebildet sein.At the opposite rear side a linking block 16 is arranged, which serves for the electrical linking of the functional modules. It has on its side walls parallel to the end faces 11 of the pneumatic base block 10 electrical plug connection elements 17, which serve for mating with corresponding interlinking blocks 16 of the other functional modules. As a result, a continuous line system is formed, which connects the functional modules with each other electrically. These may be field bus lines and / or parallel lines, wherein the power supply, if necessary, of the various functional modules of the compressed air maintenance device can be made via these lines. The interlinking blocks 16 are arranged on a holding rail 18, which serves to hold the entire compressed air maintenance device. Alternatively or additionally, the functional modules or pneumatic base blocks can also be linked directly to one another, for example by means of clamping, latching or screwing means. In the case of fieldbus lines, the interlinking block 16 contains a corresponding bus station. The electronic elements of the interlinking block 16 are arranged on a printed circuit board 19, wherein if required, a plurality of printed circuit boards can be provided. The printed circuit board 19 may include electronic control and / or diagnostic means and / or visualization means for visualizing process parameters and / or processes that may be used to control and diagnose one's own functional module or all functional modules. The control and / or diagnostic means therefore need not be arranged in each interlinking block 16. The tax- and / or diagnostic means may be formed, for example, as a microcontroller.

An der Oberseite des Pneumatikbasisblocks 10 ist ein oberer Funktionsblock 20 und an der Unterseite ein unterer Funktionsblock 21 angeordnet. Bei diesen Funktionsblöcken kann es sich um Einschaltventile, Sicherheitsventile, Druckregler, Filter, Filterregler, Durchflussmesser, Verteiler, Adapter, Trockner oder Sensoreinrichtungen, beispielsweise Drucksensoreinrichtungen oder Füllstandssensor-Einrichtungen handeln. Im Ausführungsbeispiel besitzt der obere Funktionsblock 20 eine Leiterplatte 22, der untere Funktionsblock 21 zwei miteinander elektrisch verbundene Leiterplatten 23, 24 und der Frontblock 13 eine Leiterplatte 25. Die Leiterplatten 22 bis 25 sind elektrisch mit der Leiterplatte 19 des Verkettungsblocks 16 verbunden. Hierzu dienen elektrische Steckverbindungselemente 26, wobei beim Anstecken der Funktionsblöcke die elektrischen Verbindungen automatisch hergestellt werden. Prinzipiell können auch Kabelstücke als Verbindungselemente vorgesehen sein, die dann jeweils in die entsprechenden Steckaufnehmen eingesteckt werden müssen. Falls die jeweils ausgewählten und angebrachten Funktionsblöcke 20, 21 keine elektrischen Funktionen erfüllen müssen, so können die entsprechenden Leiterplatten 22 bis 24 selbstverständlich auch entfallen und eventuell vorhandene Steckverbindungselemente 26 bleiben ohne Funktion.At the top of the pneumatic base block 10, an upper functional block 20 and at the bottom of a lower functional block 21 is arranged. These function blocks may be on-off valves, safety valves, pressure regulators, filters, filter regulators, flow meters, manifolds, adapters, dryers, or sensor devices, such as pressure sensor devices or level sensor devices. In the exemplary embodiment, the upper functional block 20 has a printed circuit board 22, the lower functional block 21 has two printed circuit boards 23, 24 connected to one another and the front block 13 has a printed circuit board 25. The printed circuit boards 22 to 25 are electrically connected to the printed circuit board 19 of the interlinking block 16. Serve for this purpose electrical plug connection elements 26, wherein the electrical connections are made automatically when connecting the function blocks. In principle, cable pieces may be provided as connecting elements, which then have to be inserted in each case in the corresponding plug-in receptacles. If the respectively selected and attached functional blocks 20, 21 do not have to fulfill any electrical functions, the corresponding printed circuit boards 22 to 24 can, of course, also be dispensed with and any existing plug-in connection elements 26 remain without function.

Sofern es sich bei den Funktionsblöcken 20, 21 um pneumatische Funktionsblöcke bzw. Funktionsblöcke mit pneumatischen Funktionen handelt, so werden die erforderlichen pneumatischen Verbindungen über schematisch dargestellte Verbindungsleitungen 27 und Schnittstellen hergestellt. Ist beispielsweise der untere Funktionsblock 21 ein Ventil oder ein Filter, so wird das entsprechende Funktionselement beim Anschluss des unteren Funktionsblocks 21 an den Pneumatikbasisblock 10 zwischen zwei Verbindungsleitungen 27 geschaltet, die nach unten hin verlaufen. Die beiden Pneumatikschnittstellen 12 an den beiden entgegengesetzten Stirnseiten 11 sind dabei jeweils mit einer dieser Verbindungsleitungen verbunden. Ist beispielsweise der obere Funktionsblock 20 ein Sensorblock, beispielsweise ein Drucksensorblock oder ein Durchflusssensorblock, so ist auch hier wiederum der Sensor an eine nach oben verlaufende Verbindungsleitung 27 oder zwischen zwei nach oben laufende Verbindungsleitungen 27 geschaltet. Auch der Verkettungsblock 16 kann beispielsweise einen Sensor enthalten, und der Anschluss erfolgt entsprechend. Ist keine pneumatische Verbindung erforderlich, so werden die äußeren Mündungen der vorhandenen Verbindungsleitungen 27 durch den jeweiligen Funktionsblock dichtend verschlossen oder zwei Verbindungsleitungen 27 werden miteinander verbunden.If the functional blocks 20, 21 are pneumatic functional blocks or functional blocks with pneumatic functions, then the required pneumatic connections are produced via schematically represented connection lines 27 and interfaces. For example, if lower function block 21 is a valve or a filter, Thus, the corresponding functional element is connected when connecting the lower function block 21 to the pneumatic base block 10 between two connecting lines 27, which extend downward. The two pneumatic interfaces 12 at the two opposite end faces 11 are each connected to one of these connecting lines. If, for example, the upper functional block 20 is a sensor block, for example a pressure sensor block or a flow sensor block, the sensor is again connected to an upwardly extending connecting line 27 or between two upwardly extending connecting lines 27. Also, the interlinking block 16 may for example contain a sensor, and the connection is made accordingly. If no pneumatic connection is required, then the outer mouths of the existing connecting lines 27 are sealingly closed by the respective functional block or two connecting lines 27 are connected to one another.

Die elektrische Verbindung 28 zwischen dem Frontblock 13 und dem Verkettungsblock 16 verläuft als Kabel durch den oberen Funktionsblock 20. Es ist selbstverständlich auch möglich, eine derartige Verbindung durch den Pneumatikbasisblock 10 zu führen, sofern dieser entsprechende elektrische Schnittstellen und Leitungen besitzt. Anstelle eines Kabels kann die elektrische Verbindung 28 auch über feste Schnittstellen und intern, beispielsweise im oberen Funktionsblock 20, geführte Verbindungsleitungen oder Verbindungselemente geführt werden.The electrical connection 28 between the front block 13 and the interlinking block 16 extends as a cable through the upper functional block 20. It is of course also possible to lead such a connection through the pneumatic base block 10, provided that it has corresponding electrical interfaces and lines. Instead of a cable, the electrical connection 28 can also be guided via fixed interfaces and internally, for example in the upper functional block 20, guided connection lines or connecting elements.

Das Anbringen des Verkettungsblocks 16, des Frontblocks 13 und der Funktionsblöcke 20, 21 am Pneumatikbasisblock 10 erfolgt über nicht dargestellte Befestigungen, wie Steck-, Rast- oder Schraubverbindungen. Durch Auswechseln von Funktionsblöcken kann dem jeweiligen Funktionsmodul eine andere Funktion zugeordnet werden. Dies kann auch im montierten Zustand der Druckluftwartungsvorrichtung erfolgen.The attachment of the interlinking block 16, the front block 13 and the functional blocks 20, 21 on the pneumatic base block 10 via not shown fasteners, such as plug-in, locking or screw. By replacing function blocks can be assigned to the respective function module another function. This can also be done in the assembled state of the compressed air maintenance device.

Anstelle eines gemäß den Figuren 1 bis 3 einteiligen Verkettungsblocks 16 kann auch ein zweiteiliger Verkettungsblock 29 gemäß Figur 2 treten. Er besteht aus einem Stromschienenelement 30, das zusammen mit anderen gleichartigen Stromschienenelementen der anderen Funktionsmodule eine durchgehende Stromschiene bildet, in der wiederum parallele Leitungen 31 oder serielle Busleitungen verlaufen. Die Leitungen 31 sind dabei als Stromschienen ausgebildet. Wird ein elektronischer Funktionsblock 32 mit dem Stromschienenelement 30 verbunden, zum Beispiel angerastet, angesteckt oder angeschraubt, so erfolgt die elektrische Kontaktierung durch Federkontakte 33 des elektronischen Funktionsblocks 32, wobei auch Steckkontakte möglich sind. Im Übrigen ist der elektronische Funktionsblock 32 entsprechend dem Verkettungsblock 16 ausgebildet. Gleiche oder gleichwirkende Bauteile sind mit denselben Bezugszeichen versehen und nicht nochmals beschrieben. Zusätzlich ist die Leiterplatte 19 mit einem Drucksensor 34 versehen, der beim Anbringen des elektronischen Funktionsblocks 32 an den Pneumatikbasisblock 10 pneumatisch mit diesem über eine Verbindungsleitung 27 verbunden wird.Instead of one according to the FIGS. 1 to 3 one-piece interlinking block 16 may also be a two-part interlinking block 29 according to FIG. 2 to step. It consists of a busbar element 30 which, together with other similar busbar elements of the other functional modules, forms a continuous busbar, in which in turn parallel lines 31 or serial bus lines run. The lines 31 are formed as busbars. If an electronic function block 32 connected to the busbar element 30, for example, snapped, infected or screwed, the electrical contact is made by spring contacts 33 of the electronic function block 32, whereby plug contacts are possible. Incidentally, the electronic function block 32 is formed corresponding to the interlinking block 16. The same or equivalent components are provided with the same reference numerals and not described again. In addition, the printed circuit board 19 is provided with a pressure sensor 34 which is pneumatically connected to the pneumatic base block 10 via a connecting line 27 when the electronic functional block 32 is attached.

Der Verkettungsblock 16 oder der Verkettungsblock 29 kann noch mit einer automatischen Konfigurationserkennung versehen sein. Dies kann über die elektrischen Steckverbindungselemente 26 erfolgen, über die die Art des angeschlossenen Blocks sensiert werden kann. Daraus kann durch die Elektronik im Verkettungsblock 16 die Gesamtfunktionalität des jeweils konfigurierten Funktionsmoduls abgeleitet werden. Entsprechende Konfigurationseinstellungen können dann automatisch durchgeführt werden. Dies ist insbesondere beim Auswechseln von Blöcken von Bedeutung, da dann automatisch die jeweils neue Konfiguration erkannt werden kann, so dass die entsprechenden Einstellungen automatisch erfolgen können.The interlinking block 16 or the interlinking block 29 can still be provided with an automatic configuration recognition. This can be done via the electrical connector elements 26, via which the type of the connected block can be sensed. From this, the overall functionality of the respectively configured function module can be derived by the electronics in the interlinking block 16. Corresponding configuration settings can then be carried out automatically become. This is particularly important when replacing blocks, since then automatically each new configuration can be detected, so that the corresponding settings can be made automatically.

Die Verkettungsblöcke 16 bzw. 29 können in unterschiedlichen Ausführungen vorliegen und wahlweise, je nach gewünschter Ausführung, mit den Pneumatikbasisblöcken 10 der jeweiligen Druckluftwartungsvorrichtung verbunden werden. So kann ein solcher Verkettungsblock 16 bzw. 29 eine Steuerbaugruppe für ein einzelnes Funktionsmodul mit einer Schnittstelle für industrieübliche, analoge und digitale Ein- und Ausgangssignale ausgebildet sein. Weiterhin kann eine solche Steuerbaugruppe verschiedene Feldbusschnittstellen für verschiedene Busarten aufweisen, z.B. ASinterface, Profibus und dergleichen. In einer weiteren Ausführung kann die Steuerbaugruppe mit einer Schnittstelle für die interne, digitale Systemvernetzung oder auch durch zusätzlich mit einer Schnittstelle für einen externen Bus versehen sein.The interlinking blocks 16 and 29 can be present in different designs and optionally, depending on the desired design, be connected to the pneumatic base blocks 10 of the respective compressed air maintenance device. Thus, such a linking block 16 or 29 may be formed a control module for a single functional module with an interface for industry standard, analog and digital input and output signals. Furthermore, such a control module may have different fieldbus interfaces for different types of bus, e.g. ASinterface, Profibus and the like. In a further embodiment, the control module may be provided with an interface for internal, digital system networking or additionally with an interface for an external bus.

Die Zahl der am Pneumatikbasisblock 10 angebrachten Blöcke ist selbstverständlich nicht auf die des Ausführungsbeispiels beschränkt, sondern es kann auch eine geringere Zahl von Blöcken angebracht sein. Im Falle der Ausbildung des Funktionsmoduls als Filtermodul kann beispielsweise nur ein unterer Funktionsblock 21 angebracht sein, der ein Filterelement enthält. Allerdings wird zusätzlich ein Verkettungsblock 16 angebracht sein, auch wenn im jeweiligen Funktionsmodul keine elektrischen Funktionen enthalten sein sollten. Dies ist jedoch nicht zwingend. Weiterhin können elektronische Steuer- und/oder Diagnosemittel und/oder Visualisierungsmittel an Stelle in einem Verkettungsblock 16 auch im oberen Funktionsblock 12 oder unteren Funktionsblock 21 angeordnet sein, wobei der jeweils andere Block dann pneumatische Funktionen enthalten kann.Of course, the number of blocks attached to the pneumatic base block 10 is not limited to that of the embodiment, but a smaller number of blocks may be provided. In the case of the formation of the functional module as a filter module, for example, only a lower functional block 21 may be attached, which contains a filter element. However, in addition, a chaining block 16 will be attached, even if no electrical functions should be included in the respective functional module. However, this is not mandatory. Furthermore, electronic control and / or diagnostic means and / or visualization means may be arranged instead of in a linking block 16 also in the upper functional block 12 or lower functional block 21, wherein the other block can then contain pneumatic functions.
