Description

Die Erfindung betrifft eine Einrichtung zur Kommunikation mit einer Anlage insbesondere zum Bedienen und Beobachten einer Automatisierungsanlage in der industriellen Fertigung.The invention relates to a device for communication with a system, in particular for operating and monitoring an automation system in industrial production.

Industrielle Automatisierungsanlagen benötigen mit ihnen in Verbindung stehende Ein- oder Ausgabegeräte, um betrieben werden zu können; hierbei handelt es sich um die sogenannte Prozesskopplung. Ausgabegeräte, oder mit anderen Worten Beobachtungsgeräte, sind zum Beispiel Kontrollleuchten, alphanumerische oder graphische Displays, die den Anlagenbediener über den aktuellen Anlagenzustand informieren. Eingabegeräte, oder mit anderen Worten Bediengeräte, sind z.B. Schalter, Drehknöpfe oder Tastaturen zur alphanumerischen Eingabe, die es dem Bediener ermöglichen, auf die Anlage einzuwirken.Industrial automation equipment requires associated input or output devices to operate; this is the so-called process coupling. Output devices, or in other words observation devices, are, for example, warning lights, alphanumeric or graphic displays which inform the plant operator about the current state of the plant. Input devices, or in other words HMI devices, are e.g. Switches, knobs or keyboards for alphanumeric input that allow the operator to interact with the system.

In herkömmlicher Weise sind zum Zweck der Kommunikation zwischen Benutzer und Anlage sogenannte Bedien- und Beobachtungsgeräte, im folgenden kurz Kommunikationsgerät genannt, fest an der Anlage selbst oder z.B. in der Fertigungshalle, in der sich die Anlage befindet, installiert. Ein typisches Kommunikationsgerät weist ein handliches Gehäuse auf, an dem Ein- und Ausgabegeräte angeordnet sind. Der Datenaustausch mit der Anlage bzw. mit deren Steuerung erfolgt über eine fest installierte Anschlussleitung.Conventionally, for the purpose of communication between user and equipment, so-called HMI devices, hereinafter referred to as communication equipment, are fixed to the equipment itself or e.g. installed in the production hall where the system is located. A typical communication device has a handy housing on which input and output devices are arranged. The data exchange with the system or with its control takes place via a permanently installed connection cable.

Bei sehr großen oder schwer zugänglichen Anlagen sind kabelgebundene Kommunikationsgeräte nicht mehr handhabbar. Hierzu existieren mobile, also frei bewegliche, drahtlos mit der Anlage kommunizierende und batteriebetriebene Kommunikationsgeräte, welche den Datenaustausch mit der Anlage per Funkverbindung abwickeln.For very large or difficult to access systems wired communication devices are no longer manageable. For this purpose, there are mobile, ie freely movable, wirelessly communicating with the system and battery-powered communication devices, which handle the data exchange with the system via wireless connection.

Gemäß verschiedener Industrienormen müssen Anlagen mit sogenannten Not-Aus-Tastern ausgerüstet sein. Diese sind rot-gelb gekennzeichnet und müssen stets einsatzbereit sein. Ein Druck auf den Not-Aus-Taster bewirkt die sofortige Spannungsabschaltung an der gesamten Anlage. Die Not-Aus-Taster sind in herkömmlicher Weise über einen separaten Not-Aus-Kreis neben dem Feldbus an der Anlage verlegt bzw. mit dieser verbunden. Alternativ zum Not-Aus-Kreis kann in jüngerer Zeit zum Anschluss der Not-Aus-Taster ein sogenannter sicherheitsgerichteter Feldbus verwendet werden, der zur Not-Aus-Abschaltung der entsprechenden Anlage die gleichen Sicherheitsreserven bietet wie ein separater Not-Aus-Kreis.According to various industrial standards, systems must be equipped with so-called emergency stop buttons. These are marked red-yellow and must always be ready for use. Pressing the emergency stop button causes the power to be switched off immediately on the entire system. The emergency stop buttons are routed in a conventional manner via a separate emergency stop circuit next to the fieldbus on the system or connected to this. As an alternative to the emergency stop circuit, a so-called safety-oriented field bus can be used recently for connecting the emergency stop button, which provides the same safety reserves for emergency stop of the corresponding system as a separate emergency stop circuit.

Auch die mobilen, drahtlos arbeitenden Kommunikationsgeräte sind in vielen Fällen mit Sicherheitsfunktionen ausgestattet, mit Hilfe derer im Gefahrenfalle der sichere Anlagenzustand erreicht werden kann. Da derartige Geräte zwangsläufig batteriebetrieben sind und die Informationsübertragung über eine Funkstrecke erfolgt, ist die Dauerverfügbarkeit der Not-Aus-Funktion nicht gegeben. Ein Abbruch der Funkverbindung oder eine vollständige Entleerung des im mobilen Kommunikationsgerätes befindlichen Akkus würde nämlich zum Abreißen der Kommunikation zwischen Kommunikationsgerät und Anlage führen, weshalb der Not-Aus-Taster in diesem Fall wirkungslos wäre.The mobile, wireless communication devices are also equipped in many cases with security functions, with the help of which the safe state of the system can be achieved in case of danger. Since such devices are necessarily battery operated and the information is transmitted over a radio link, the availability of the emergency stop function is not available. A termination of the radio link or a complete emptying of the battery located in the mobile communication device would lead namely to tearing off the communication between the communication device and system, so the emergency stop button would be ineffective in this case.

Für funkbasierte Kommunikationsgeräte ist deshalb die sogenannte Stop-Funktion realisiert. Die Stop-Funktion wird in der Regel durch einen Stop-Taster am Kommunikationsgerät realisiert, der wegen seiner eingeschränkten Verfügbarkeit aber nicht rot-gelb ausgeführt sein darf. Bei ordnungsgemäß funktionierendem Kommunikationsgerät bewirkt ein Druck auf diesen Taster ebenfalls den sofortigen Stillstand der Anlage bzw. die sofortige Spannungsabschaltung an der gesamten Anlage, besitzt also die gleiche Funktionalität wie der Not-Aus-Taster.For radio-based communication devices, therefore, the so-called stop function is realized. The stop function is usually implemented by a stop button on the communication device, which may not be red-yellow due to its limited availability. If the communication device is functioning properly, pressing this button will also cause the system to shut down immediately or to immediately switch off the power to the entire system, ie it will have the same functionality as the emergency stop button.

Ein weiteres Sicherheitsrisiko ist, dass der am mobilen Kommunikationsgerät befindliche Stop-Taster nicht zwangsläufig einer bestimmten Maschine zuzuordnen ist, wenn das mobile Kommunikationsgerät an beliebiger Stelle in einer Fertigungshalle abgelegt ist. Selbst bei funktionierendem Kommunikationsgerät bewirkt ein Druck auf den Stop-Taster deshalb nicht zwangsläufig den Stillstand der sich in der Nähe befindenden Maschine.Another security risk is that the stop button located on the mobile communication device is not necessarily assigned to a specific machine if the mobile communication device is stored anywhere in a production hall. Therefore, even with a functioning communication device, pressing the stop button does not necessarily cause the machine in the vicinity to come to a standstill.

Gemäß verschiedener Sicherheitsvorschriften müssen deshalb mobile Bediengeräte, die nicht in Betrieb sind, z.B. weggeschlossen werden. Das Wegschließen des Gerätes ist zum einen organisatorisch aufwendig, zum anderen sind derartige administrative Vorschriften sehr fehleranfällig, z.B. wenn das Wegschließen des Gerätes vergessen wird.Therefore, according to various safety regulations, mobile operating devices that are not in operation, e.g. be locked away. The path closure of the device is on the one hand organisationally complex, on the other hand such administrative regulations are very error-prone, e.g. if the path closing of the device is forgotten.

Aufgabe der vorliegenden Erfindung ist es, eine Einrichtung anzugeben, bei der die sicherheitsrelevante Handhabung eines mobilen Kommunikationsgerätes vereinfacht ist.Object of the present invention is to provide a device in which the security-relevant handling of a mobile communication device is simplified.

Die Aufgabe wird gelöst durch eine Einrichtung zur Kommunikation mit einer Anlage, insbesondere zum Bedienen und Beobachten einer Automatisierungsanlage in der industriellen Fertigung, mit einem mobilen Kommunikationsgerät zum drahtlosen Datenaustausch mit der Anlage. Mit der Anlage fest verbunden ist eine Ablage, in der das Kommunikationsgerät ablegbar ist. An der Ablage ist ein Not-Aus-Taster zur Abschaltung der Anlage angebracht. Ein ähnliches System wird in DE 19 946 441 offenbart.The object is achieved by a device for communication with a system, in particular for operating and monitoring an automation system in industrial production, with a mobile communication device for wireless data exchange with the system. Firmly connected to the system is a shelf in which the communication device can be stored. The shelf has an emergency stop button for switching off the system. A similar system will be in DE 19 946 441 disclosed.

Ablagen für mobile Kommunikationsgeräte sind in der Regel, z.B. in Form einer sogenannten Docking-Station, mit einer Stromversorgung ausgerüstet, über welche der sich als Batterie im Kommunikationsgerät befindliche Akkumulator aufgeladen wird.Trays for mobile communication devices are typically, e.g. in the form of a so-called docking station, equipped with a power supply via which the battery located in the communication device accumulator is charged.

Solange das Kommunikationsgerät in der Ablage liegt, ist es also jederzeit mit ausreichend Energie versorgt und betriebsbereit, solange die Funkverbindung funktioniert. Dies erhöht die Verfügbarkeit des am Kommunikationsgerät angebrachten Stop-Tasters, so lange sich das Kommunikationsgerät in der Ablage befindet.As long as the communication device is in the storage, it is therefore always supplied with sufficient energy and ready for use, as long as the radio connection works. This increases the availability of the stop button attached to the communication device as long as the communication device is in the storage.

Die Docking Station bildet eine definierte Ablage für das Bediengerät, d.h. nach Beendigung der Benutzung desselben sollte dieses stets in der Ablage abgelegt werden. Dies kann gegebenenfalls durch eine entsprechende Überwachung, z.B. durch den Werkstattmeister sichergestellt werden. Eine Zuordnung eines mobilen Bediengerätes zu einer bestimmten Anlage bzw. Maschine ist dadurch verbessert, dass die Ablage an der Anlage fest verbunden ist. Das Kommunikationsgerät wird nicht an anderer Stelle abgelegt, z.B. in der Meisterkabine und ist somit der Anlage deutlicher zugeordnet.The docking station forms a defined storage for the operating device, i. after completion of the use of the same should always be stored in the filing. Optionally, this may be done by appropriate monitoring, e.g. be ensured by the workshop master. An assignment of a mobile operating device to a specific system or machine is improved in that the filing is firmly connected to the system. The communication device is not stored elsewhere, e.g. in the master cabin and thus the plant is assigned more clearly.

Der Not-Aus-Taster an der fest installierten Ablage ist fest verdrahtet und somit jederzeit funktionsfähig. Sollte bei einliegendem Kommunikationsgerät die Funkverbindung unterbrochen sein, und damit der Stop-Taster funktionslos, steht, ein Not-Aus-Taster in unmittelbarer Reichweite, nämlich direkt neben dem Kommunikationsgerät, zur Verfügung. Auch weiß der Bediener so im Falle des aus der Ablage entnommenen Kommunikationsgerätes und Abreißens des Funkkontaktes, dass zumindest am Ablageort des Kommunikationsgerätes ein Not-Aus-Taster zur Verfügung steht, zu dem er im Gefahrenfalle eilen kann.The emergency stop button on the fixed shelf is hard-wired and thus functional at all times. If the radio connection is interrupted with the communication device connected, and thus the stop button is inoperative, there is an emergency stop button in the immediate range, namely directly next to the communication device. Also, the operator knows so in the case of removed from the tray communication device and tearing off the radio contact that at least at the storage location of the communication device, an emergency stop button is available, to which he can hurry in case of danger.

Der administrative Aufwand für das Wegschließen des Kommunikationsgerätes entfällt, da es wegen der Verfügbarkeit eines dauerhaft funktionierenden Not-Aus-Tasters zulässig ist, das Kommunikationsgerät in der Ablageschale dauerhaft abzulegen.The administrative effort for the path closing the communication device is eliminated because it is permissible because of the availability of a permanently functioning emergency stop button to permanently store the communication device in the tray.

Es existieren also nur zwei erlaubte Zustände für den Aufenthaltsort des kabellosen Bediengerätes, nämlich in der Docking Station oder außerhalb der Docking Station, aber im Funkbetrieb. So lässt sich der Aufenthaltsort des Bediengerätes stets überwachen. Auch hier ist zwar eine administrative Aufgabe zu erfüllen, nämlich die Ablage des Kommunikationsgerätes in der an der Anlage angebrachte Ablage, jedoch ist diese weniger fehleranfällig. Eine Fehlablage des Gerätes ist schneller bemerkbar, z.B. bei Schichtende, da der Anlagenbediener dies sofort bemerkt.Thus, there are only two allowed states for the location of the wireless control unit, namely in the docking station or outside the docking station, but in radio mode. This allows the location of the HMI device always monitor. Again, although an administrative task is to be met, namely the storage of the communication device in the attached to the system storage, but this is less error prone. An erroneous storage of the device is noticeable faster, eg at the end of the shift, as the system operator immediately notices this.

Für eine weitere Beschreibung der Erfindung wird auf die Ausführungsbeispiele der Zeichnungen verwiesen. Es zeigen jeweils in einer Prinzipskizze:

Fig. 1
eine Automatisierungsanlage mit mobilem Bediengerät im Funkbetrieb, und Not-Aus-Tastern, und einem sicherheitsgerichteten Feldbus,
Fig. 2
die Automatisierungsanlage aus Fig. 1, jedoch mit mobilem Bediengerät in der Ablage, herkömmlichem Feldbus und zusätzlichem Not-Aus-Kreis.
For a further description of the invention reference is made to the embodiments of the drawings. In each case, they show in a schematic diagram:
Fig. 1
an automation system with mobile operating device in radio mode, and emergency stop buttons, and a safety-related fieldbus,
Fig. 2
the automation system off Fig. 1 , but with mobile operating device in the storage, conventional fieldbus and additional emergency stop circuit.

Fig. 1 zeigt eine Automatisierungsanlage 2 mit einem mobilen Kommunikationsgerät 4, welches mit der Automatisierungsanlage 2 prozessgekoppelt ist, d.h. zum Bedienen und Beobachten der Anlage 2 mit dieser Daten drahtlos austauscht. Fig. 1 shows an automation system 2 with a mobile communication device 4, which is process-coupled with the automation system 2, ie wirelessly exchanges for operating and monitoring the system 2 with this data.

Die Automatisierungsanlage 2 umfasst eine Maschine 6 und eine die Maschine 6 steuernde Steuerung 8, sowie eine Ablage 10 für das Kommunikationsgerät 4 und eine Funkbasisstation 12. In der Automatisierungsanlage 2 ist außerdem ein erster Not-Aus-Taster 14 enthalten, der neben der Steuerung 8 an einer Wand der nicht dargestellten, die Maschine 6 enthaltenden Fertigungshalle fest angebracht ist. Ein zweiter Not-Aus-Taster 16 ist am Gehäuse 18 der Ablage 10 angebracht. Die Ablage 10 wiederum ist fest an der Maschine 6 installiert.The automation system 2 comprises a machine 6 and a controller 6 controlling the machine 8, and a tray 10 for the communication device 4 and a radio base station 12. In the automation system 2, a first emergency stop button 14 is also included, in addition to the controller. 8 on a wall of the machine, not shown, the machine 6 containing fixedly mounted. A second emergency stop button 16 is attached to the housing 18 of the tray 10. The tray 10 in turn is firmly installed on the machine 6.

Sämtliche Komponenten der Automatisierungsanlage 2 sind untereinander über einen sicherheitsgerichteten Feldbus 20 verbunden. Sicherheitsgerichtet bedeutet in diesem Zusammenhang, dass bei einem derartigen Feldbus 20 die Funktionalität der Not-Aus-Taste 14,16 zu jeder Zeit gewährleistet ist. Die Not-Aus-Taster 14,16 dürfen deshalb in rot-gelber Farbe ausgeführt sein. Ein Druck auf einen Not-Aus-Taster 14, 16 führt zu unmittelbaren Spannungsabschaltung an sämtlichen Komponenten der Automatisierungsanlage 2.All components of the automation system 2 are interconnected via a safety-related fieldbus 20. Security-oriented in this context means that in such a fieldbus 20, the functionality of Emergency stop button 14,16 is ensured at all times. The emergency stop buttons 14,16 may therefore be made in red-yellow color. A pressure on an emergency stop button 14, 16 leads to immediate voltage disconnection on all components of the automation system. 2

Das Kommunikationsgerät 4 weist nicht näher dargestellte Ein- und Ausgabegeräte 22 auf, z.B. in Form eines von Bedienknöpfen umgebenden Displays, mit denen ein das Kommunikationsgerät 4 bedienender, nicht dargestellter Bediener die Automatisierungsanlage 2 Bedienen und Beobachten kann. Die Kommunikation zwischen Kommunikationsgerät 4 und Anlage 2 erfolgt zwischen den an der Funkbasisstation 12 und am Kommunikationsgerät 4 angebrachten Antennen 24,26 entlang einer durch einen Doppelpfeil angedeuteten Funkstrecke 28.The communication device 4 has input and output devices 22 (not shown), e.g. in the form of a surrounding of control buttons display, with which a communication device 4 serving, not shown operator the automation system 2 can operate and monitor. The communication between communication device 4 and system 2 takes place between the antennas 24, 26 attached to the radio base station 12 and the communication device 4 along a radio path 28 indicated by a double arrow.

Am Kommunikationsgerät 4 ist ein Stop-Taster 30 angebracht. Der Stop-Taster 30 besitzt die gleiche Funktionalität wie die Not-Aus-Taster 14,16. Bei Druck auf den Stop-Taster 30 erfolgt die Spannungsabschaltung in der gesamten Automatisierungsanlage 2. Da sich der Stop-Taster 30 jedoch an dem batteriebetriebenen Kommunikationsgerät 4 befindet, welches außerdem frei beweglich ist, darf er entsprechend der oben genannten Industrienormen nicht als rot-gelber Not-Aus-Taster gekennzeichnet sein. Das Funktionieren des Stopp-Tasters 30 setzt nämlich voraus, dass das Kommunikationsgerät 4 aus der darin enthaltenen, nicht dargestellten Batterie mit Strom versorgt ist, diese Batterie also nicht vollständig entleert ist und dass die Funkstrecke 28 einwandfrei funktioniert. Außerdem darf das Kommunikationsgerät 4 sich z.B. nicht außerhalb der Reichweiter der Funkstrecke 28 entfernt von der Funkbasisstation 12 befinden.At the communication device 4, a stop button 30 is attached. The stop button 30 has the same functionality as the emergency stop button 14, 16. When the stop button 30 is pressed, the voltage is switched off in the entire automation system 2. However, since the stop button 30 is located on the battery-powered communication device 4, which is also freely movable, it must not be red-yellow according to the above-mentioned industry standards Emergency stop button must be marked. The functioning of the stop button 30 presupposes namely that the communication device 4 is powered from the battery contained therein, not shown, so this battery is not completely emptied and that the radio link 28 is working properly. In addition, the communication device 4 may be e.g. not located outside the range of the radio link 28 remote from the radio base station 12.

Der Bediener entnimmt bei Beginn der Benutzung das Kommunikationsgerät 4 aus der Ablage 10. Deshalb weiß er in diesem Fall, dass bei einer Betriebsstörung am Kommunikationsgerät 4 zumindest an der Ablage 10 ein dauerhaft funktionierender Not-Aus-Taster 16 zur Verfügung steht, zu dem er im Gefahrenfall eilen kann. Da das Kommunikationsgerät 4 außerdem der Ablage 10 fest zugeordnet ist, ist er nicht dazu veranlasst, das Kommunikationsgerät 4 an irgendeiner anderen Stelle abzulegen, da es auch nur in der Ablage 10, in der sich eine nichtdargestellte Spannungsversorgung befindet, wieder aufgeladen wird.The operator removes the communication device 4 from the tray 10 at the beginning of use. Therefore, in this case, he knows that in the event of a malfunction in the communication device 4, at least on the tray 10 a permanently functioning Emergency stop button 16 is available to which he can hurry in case of danger. In addition, since the communication device 4 is dedicated to the tray 10, it is not caused to drop the communication device 4 at any other location because it is also recharged only in the tray 10 in which a power supply not shown.

Die Situation eines in die Ablage 10 eingelegten Kommunikationsgerätes 4 ist in Fig. 2 dargestellt.The situation of an inserted in the tray 10 communication device 4 is in Fig. 2 shown.

Fig. 2 zeigt die gleiche Automatisierungsanlage wie Fig. 1, wobei hier der sicherheitsgerichtete Feldbus 20 durch einen Standardfeldbus 32 ohne spezielle Sicherheitsmerkmale ersetzt ist. Aus diesem Grund sind die Not-Aus-Taster 14, 16 nicht über den Feldbus 32, sondern über einen separat verlegten Not-Aus-Kreis 34 miteinander verbunden. Der Not-Aus-Kreis 34 wirkt auf die Maschine 6 und kann außerdem, wie im Zusammenhang mit Fig. 1 beschrieben über den Stop-Taster 30 ausgelöst werden. Deshalb ist auch die Funkbasisstation 12, bei der das entsprechende Funksignal eingeht, am Not-Aus-Kreis 34 angeschlossen, um das Not-Aus-Signal zu erzeugen. Fig. 2 shows the same automation system as Fig. 1 Here, the safety-related fieldbus 20 is replaced by a standard fieldbus 32 without special security features. For this reason, the emergency stop buttons 14, 16 are not connected to each other via the field bus 32, but via a separately installed emergency stop circuit 34. The emergency stop circuit 34 acts on the machine 6 and can also, as related to Fig. 1 described via the stop button 30 are triggered. Therefore, the radio base station 12 receiving the corresponding radio signal is also connected to the emergency stop circuit 34 to generate the emergency stop signal.

In Fig. 2 liegt das Kommunikationsgerät 4 in seiner ihm zugeordneten Ablage 10 ein und ist außer Betrieb gesetzt. Es existieren keine Funkverbindung zwischen den Antennen 24 und 26, weshalb ein Druck auf den Stop-Taster 30 wirkungslos ist. Dennoch bietet die in Fig. 2 dargestellte Situation eine gemäß Industrienorm zulässige Anordnung, da sich in unmittelbarer Nähe des Stop-Tasters 30, nämlich am Gehäuse 18 der Ablage 10 der Not-Aus-Taster 16 befindet, welcher jederzeit betriebsbereit ist. Da der Not-Aus-Taster 16 rot-gelb ausgeführt ist, ist ein Bediener der Anlage auch nicht verleitet, im Gefahrenfall zuerst auf den z.B. grau ausgeführten Stoptaster 30 zu drücken, sondern wird sofort den ihm bekannten und einprägsamen rot-gelben Not-Aus-Taster 16 betätigen.In Fig. 2 is the communication device 4 in its associated tray 10 and is disabled. There is no radio connection between the antennas 24 and 26, which is why a pressure on the stop button 30 is ineffective. Nevertheless, the in Fig. 2 illustrated situation a permissible according to industry standard arrangement, since in the immediate vicinity of the stop button 30, namely the housing 18 of the tray 10 of the emergency stop button 16 is located, which is ready for use at any time. Since the emergency stop button 16 is executed red-yellow, an operator of the system is not tempted to press in case of danger first on the example gray running stop button 30, but is immediately the familiar and memorable red-yellow emergency stop Press button 16.

Ein weiterer Sicherheitsaspekt in Fig. 2 ist, dass z.B. bei Schichtwechsel leicht kontrollierbar ist, ob das Kommunikationsgerät 4 auch in seiner Ablage 10 eingelegt ist. Dies ist vor allem deshalb sinnvoll, da über die Ablage 10 im Regelfall auch eine Aufladung des im Kommunikationsgerät 4 befindlichen, nicht dargestellten Akkumulators stattfindet und so zu Schichtbeginn der nachfolgenden Schicht das Kommunikationsgerät 4 wieder geladen und somit betriebsbereit ist.Another security aspect in Fig. 2 is that, for example, at shift change is easily controlled whether the communication device 4 is also inserted in its tray 10. This is particularly useful because on the shelf 10 usually also a charge of the communication device 4 located in the accumulator, not shown, takes place and so at the beginning of the shift layer, the communication device 4 is recharged and thus ready for operation.
