In principle, field devices are all devices that are used close to the process and that provide or process process-relevant information. For example, field devices are used to detect and / or influence process variables. Sensor systems are used to record process variables. These are used, for example, for pressure and temperature measurement, conductivity measurement, flow measurement, pH measurement, level measurement, etc. and record the corresponding process variables pressure, temperature, conductivity, pH value, level, flow etc. Actuator systems are used to influence process variables. These are, for example, pumps or valves that can influence the flow of a liquid in a pipe or the level in a container.

Aus dem Stand der Technik sind bereits Feldgeräte bekannt geworden, die in industriellen Anlagen zum Einsatz kommen. In der Automatisierungstechnik ebenso wie in der Fertigungsautomatisierung werden vielfach Feldgeräte eingesetzt. Als Feldgeräte werden im Prinzip alle Geräte bezeichnet, die prozessnah eingesetzt werden und die prozessrelevante Informationen liefern oder verarbeiten. So werden Feldgeräte zur Erfassung und/oder Beeinflussung von Prozessgrößen verwendet. Zur Erfassung von Prozessgrößen dienen Sensorsysteme. Diese werden beispielsweise zur Druck- und Temperaturmessung, Leitfähigkeitsmessung, Durchflussmessung, pH-Messung, Füllstandmessung, etc. verwendet und erfassen die entsprechenden Prozessvariablen Druck, Temperatur, Leitfähigkeit, pH-Wert, Füllstand, Durchfluss etc. Zur Beeinflussung von Prozessgrößen werden Aktorsysteme verwendet. Diese sind beispielsweise Pumpen oder Ventile, die den Durchfluss einer Flüssigkeit in einem Rohr oder den Füllstand in einem Behälter beeinflussen können. Neben den zuvor genannten Messgeräten und Aktoren werden unter Feldgeräten auch Remote I/Os, Funkadapter bzw. Field devices are already known from the prior art, which are used in industrial plants. Field devices are often used in automation technology as well as in factory automation. In principle, field devices are all devices that are used close to the process and that provide or process process-relevant information. For example, field devices are used to detect and / or influence process variables. Sensor systems are used to record process variables. These are used, for example, for pressure and temperature measurement, conductivity measurement, flow measurement, pH measurement, level measurement, etc. and record the corresponding process variables pressure, temperature, conductivity, pH value, level, flow etc. Actuator systems are used to influence process variables. These are, for example, pumps or valves that can influence the flow of a liquid in a pipe or the level in a container. In addition to the previously mentioned measuring devices and actuators, field devices also include remote I / Os, radio adapters or
allgemein Geräte verstanden, die auf der Feldebene angeordnet sind. generally understood devices that are arranged at the field level.
Eine Vielzahl solcher Feldgeräte wird von der Endress+Hauser-Gruppe produziert und vertrieben. A large number of such field devices are produced and sold by the Endress + Hauser Group.
In modernen Industrieanlagen sind Feldgeräte in der Regel über Kommunikationsnetzwerke wie beispielsweise Feldbusse (Profibus®, Foundation® Fieldbus, HART®, etc.) mit übergeordneten Einheiten verbunden. Bei den übergeordneten Einheiten handelt es sich um Steuereinheiten, wie beispielsweise eine SPS (speicheiprogrammierbare Steuerung) oder einen PLC (Programmable Logic Controller). Die übergeordneten Einheiten dienen unter anderem zur Prozesssteuerung, sowie zur Inbetriebnahme der Feldgeräte. Die von den Feldgeräten, insbesondere von Sensoren, erfassten Messwerte werden über das jeweilige Bussystem an eine (oder gegebenenfalls mehrere) übergeordnete Einheiten) übermittelt, die die Messwerte gegebenenfalls weiterverarbeiten und an den Leitstand der Anlage weiterleiten. Der Leitstand dient zur Prozessvisualisierung, In modern industrial plants, field devices are generally connected to higher-level units via communication networks, such as fieldbuses (Profibus®, Foundation® Fieldbus, HART®, etc.). The higher-level units are control units, such as a PLC (programmable controller) or a PLC (Programmable Logic Controller). Among other things, the higher-level units are used for process control and commissioning of the field devices. The measured values acquired by the field devices, in particular by sensors, are transmitted via the respective bus system to one (or possibly several) higher-level units, which optionally further process the measured values and forward them to the control center of the system. The control desk is used for process visualization,
Prozessüberwachung und Prozessteuerung über die übergeordneten Einheiten. Daneben ist auch eine Datenübertragung von der übergeordneten Einheit über das Bussystem an die Feldgeräte erforderlich, insbesondere zur Konfiguration und Parametrierung von Feldgeräten sowie zur Ansteuerung von Aktoren. Process monitoring and process control via the higher-level units. In addition, a data transmission from the higher-level unit via the bus system to the field devices is required, in particular for the configuration and parameterization of field devices and for the control of actuators.
Im Falle eines am Feldgerät aufgetretenen Fehlers erstellt dieses eine Diagnosemeldung, welche in der Leitstelle empfangen wird. Je nach Typ des aufgetretenen Fehlers wird ein Servicetechniker beauftragt, welcher anschließend das am Feldgerät aufgetretene Problem beheben soll. Mitunter besteht ein großer Zeitabstand zwischen aufgetretenem Fehler und Behebung des Fehlers am Feldgerät. Insbesondere in kritischen Fällen ist es allerdings unerlässlich, diese Zeitspanne so gering wie möglich zu halten. In the event of an error occurring on the field device, this generates a diagnostic message that is received at the control center. Depending on the type of error that has occurred, a service technician will be appointed who will then remedy the problem that has occurred on the field device. Sometimes there is a large time interval between the error that has occurred and the error on the field device. However, especially in critical cases, it is essential to keep this period as low as possible.
Ausgehend von dieser Problematik liegt der Erfindung die Aufgabe zugrunde, eine Vorrichtung und ein Verfahren vorzustellen, welche es erlauben, einen Bediener unmittelbar auf einen aufgetretenen Diagnosefall eines Feldgeräts hinzuweisen.

Der große erfindungsgemäße Vorteil besteht darin, dass Informationen über einen Diagnosefall auf schnell einen zuständigen Bediener erreichen. Der Bediener trägt die Smartwatch am Handgelenk stets bei sich. Auf dieser sind die einzelnen Feldgeräte visualisiert, bzw. deren Gerätestatus. Auf einen Blick ist für den Bediener ersichtlich, ob alle Feldgeräte bestimmungsgerecht in Betrieb sind, oder ob es einen Diagnosefall gibt. Die Schwere, und somit die Dringlichkeit zur Behebung, des Diagnosefalls wird dem Bediener anhand der klassifizierten Gerätestatus angezeigt. Die Smartwatch hindert den Bediener aufgrund der Anbringung am Handgelenk und aufgrund der typischerweise geringen Abmessungen nicht am Ausführen seiner typischen alltäglichen Tätigkeiten. The great advantage of the invention is that information about a diagnostic case quickly reach a responsible operator. The operator always carries the smartwatch with him on his wrist. On this the individual field devices are visualized, or their device status. At a glance, the operator can see whether all field devices are operating correctly or whether there is a diagnostic case. The severity, and hence urgency, of the diagnostic case is displayed to the operator based on the classified device status. The smartwatch does not prevent the operator from performing their typical day-to-day activities due to their wrist attachment and typically small footprint.

Fig. 2: ein Ausführungsbeispiel der Darstellungsfunktion erfindungsgemäßen Smartwatch. Fig. 2: an embodiment of the display function smartwatch according to the invention.
Fig.1 zeigt ein Ausführungsbeispiel des erfindungsgemäßen Verfahrens. Hierbei ist eine Anlage AN der Prozessautomatisierung dargestellt, in welcher drei Feldgeräte F1 , F2, F3 eingebunden sind. Die Feldgeräten F1 , F2, F3 stehen über einen Feldbus FB mit einer übergeordneten Einheit ÜE, beispielsweise einer SPS oder einer Remote-I/O, in Kommunikationsverbindung. Die übergeordnete Einheit selbst ist mittels eines industriellen Ethernetnetzwerks mit der Leitwarte der Anlage AN in Verbindung, welche beispielsweise eine Workstation-PC WS zum Steuern und/oder Verwalten der Feldgeräte F1 , F2, F3 umfasst. 1 shows an embodiment of the method according to the invention. Here, a system AN of process automation is shown, in which three field devices F1, F2, F3 are integrated. The field devices F1, F2, F3 are in communication communication via a field bus FB with a superordinated unit UE, for example a PLC or a remote I / O. The higher-level unit itself is connected by means of an industrial Ethernet network to the control room of the installation AN, which comprises, for example, a workstation PC WS for controlling and / or managing the field devices F1, F2, F3.
Des Weiteren ist der Feldbus FB mit einem Gateway GW in Kommunikationsverbindung. Dieses Gateway GW hört den über den Feldbus FB übertragenen Datenverkehr mit und übermittelt die mitgehörten Daten, beispielsweise Messwerte und/oder Diagnosemeldungen der Feldgeräte F1 , F2, F3, an einen Server SE. Auf der Server SE ist beispielsweise eine Plant-Asset-Management- Applikation implementiert. Furthermore, the fieldbus FB is in communication with a gateway GW. This gateway GW listens to the data traffic transmitted via the fieldbus FB and transmits the monitored data, for example measured values and / or diagnostic messages of the field devices F1, F2, F3, to a server SE. For example, a plant asset management application is implemented on the server SE.
Für den Fall, dass bei einem Feldgerät F1 , F2, F3 ein Fehler auftritt, erstellt dieses eine In the event that an error occurs in a field device F1, F2, F3, this creates one
Diagnosemeldung. Diese Diagnosemeldung wird an die Leitwarte weitergeleitet, wobei anschließend ein Servicetechniker informiert und zur Behebung des Problems an das betreffende Feldgerät F1 , F2, F3 bestellt wird. Zur Beschleunigung dieses Prozesses kann ein Bediener, welcher sich bereits in der Anlage AN befindet, eine Smartwatch SW verwenden. Diese bietet die Möglichkeit, dass der Bediener direkt über den Gerätestatus der Feldgeräte i F1 , F2, F3 nformiert wird. Hierzu weist die Smartwatch SW eine Sende-/Empfangseinheit SE auf, welche zum Abrufen von Diagnosemeldungen der Feldgeräte F1 , F2, F3 verwendet wird. Die Sende-/Empfangseinheit nutzt beispielsweise den Funkstandard Bluetooth LE. Diagnostic message. This diagnostic message is forwarded to the control room, after which a service technician is informed and ordered to remedy the problem to the relevant field device F1, F2, F3. To speed up this process, an operator who is already in the plant AN can use a smartwatch SW. This offers the possibility that the operator is directly informed about the device status of the field devices i F1, F2, F3. For this purpose, the smartwatch SW on a transmitting / receiving unit SE, which is used for retrieving diagnostic messages of the field devices F1, F2, F3. The transmitting / receiving unit uses, for example, the radio standard Bluetooth LE.
Zum Abrufen der Diagnosemeldungen stehen prinzipiell zwei Methoden zur Verfügung. In einer ersten Variante verbindet sich die Smartwatch SW mittels der Sende-/Empfangseinheit SE direkt mit den Feldgeräten F1 , F2, F3. Die Feldgeräte F1 , F2, F3 weisen hierfür selbst eine Funkeinheit auf. Es handelt sich hierbei insbesondere nicht um die Hauptkommunikationsschnittstelle des jeweiligen Feldgeräts F1 , F2, F3, sondern um eine Kommunikationsschnittstelle zum Etablieren eines zusätzlichen Kommunikationskanals. Nach dem Etablieren der Verbindung ruft die Smartwatch SW in regelmäßigen Zeitabständen besagte Diagnosemeldungen von den Feldgeräten F1 , F2, F3 ab. There are basically two methods available for retrieving the diagnostic messages. In a first variant, the smartwatch SW connects directly to the field devices F1, F2, F3 by means of the transmitting / receiving unit SE. The field devices F1, F2, F3 have for this purpose even a radio unit. This is in particular not the main communication interface of the respective field device F1, F2, F3, but a communication interface for establishing an additional communication channel. After establishing the connection, the smartwatch SW retrieves said diagnostic messages from the field devices F1, F2, F3 at regular time intervals.
In einer zweiten Variante verbindet sich die Smartwatch SW mit dem Server SE. Es kann hier vorgesehen sein, dass die Smartwatch SW mittels der Sende-/Empfangseinheit SE den Server SE direkt kontaktiert, oder diesen indirekt, beispielsweise über einen Zugriff auf das Gateway GW, kontaktiert. Alternativ kann die Smartwatch SW mittels eines zusätzlichen Funkmoduls auch per Internet auf den Server SE zugreifen. Nach dem Etablieren der Verbindung ruft die Smartwatch SW in regelmäßigen Zeitabständen besagte Diagnosemeldungen der Feldgeräte F1 , F2, F3 von dem Server SE ab. Für den Abruf über Internet muss sich der Bediener nicht in der Anlage AN aufhalten. In a second variant, the smartwatch SW connects to the server SE. It may be provided here that the smartwatch SW directly contacts the server SE by means of the transmitting / receiving unit SE, or contacts it indirectly, for example via access to the gateway GW. Alternatively, the smartwatch SW can also access the server SE via the Internet by means of an additional radio module. After establishing the connection, the smartwatch SW retrieves said diagnostic messages of the field devices F1, F2, F3 from the server SE at regular time intervals. For the retrieval via the Internet, the operator does not have to be in the system AN.
Alternativ ist die Smartwatch SW dazu ausgestaltet, die Diagnosemeldungen mittels beiden Varianten simultan zu empfangen. Die Smartwatch SW überprüft anschließend die empfangenen Daten miteinander und gibt einen Alarm im Falle einer Diskrepanz zwischen den empfangenen Daten von dem Server SE und den direkt von den Feldgeräten F1 , F2, F3 empfangenen Daten aus. Die abgerufenen Diagnosemeldungen werden von der Smartwatch SW analysiert und in verschiedene Gerätestatus klassifiziert. Beispielsweise erfolgt die Klassifizierung anhand der Namur-Empfehlung. Die klassifizierten Gerätestatus werden anschließend auf einer Anzeigeeinheit AE der Smartwatch visualisiert. Fig. 2 zeigt ein Beispiel für eine solche Visualisierung: Alternatively, the smartwatch SW is configured to simultaneously receive the diagnostic messages by means of both variants. The smartwatch SW then checks the received data with each other and issues an alarm in the event of a discrepancy between the received data from the server SE and the data received directly from the field devices F1, F2, F3. The retrieved diagnostic messages are analyzed by the Smartwatch SW and classified into various device statuses. For example, the classification is based on the Namur recommendation. The classified device statuses are then visualized on a display unit AE of the smartwatch. Fig. 2 shows an example of such a visualization:
Auf der Anzeigeeinheit AE der Smartwatch sind mehrere Symbole SY dargestellt. Jedes Symbol SY korrespondiert zu einem Feldgerät F1 , F2, F3. Die Erscheinung der Symbole SY, also deren Form, Farbe und/oder Größe wird durch den jeweilig aktuellen Gerätestatus eines Feldgeräts F1 , F2, F3 bestimmt. In dem in Fig. 2 gezeigten Beispiel wurde für die Feldgeräte F1 und F3 keine On the display unit AE of the smartwatch several symbols SY are shown. Each symbol SY corresponds to a field device F1, F2, F3. The appearance of the symbols SY, ie their shape, color and / or size, is determined by the respective current device status of a field device F1, F2, F3. In the example shown in FIG. 2, the field devices F1 and F3 have no
Diagnosemeldung empfangen - somit weisen die Feldgeräte F1 und F3 den Gerätestatus„normaler Betrieb" auf. Das jeweilige Symbol SY für die Feldgeräte F1 und F3 ist daher unscheinbar visualisiert. Für Feldgerät F2 wurde eine Diagnosemeldung empfangen - das Feldgerät F2 erhält den Gerätestatus„Störung". Das Symbol SY für das Feldgerät F2 ist vergrößert, erfährt eine Formänderung und wird prominent auf der Anzeigeeinheit AE angeordnet. Zusätzlich gibt die Smartwatch ein Alarmsignal aus, beispielsweise in Form eines akustischen Signals und/oder eines Vibrationssignals. Thus, the field devices F1 and F3 have the device status "normal operation." The respective symbol SY for the field devices F1 and F3 is therefore inconspicuous visualized. A diagnostic message was received for field device F2 - the field device F2 receives the device status "Fault." The symbol SY for the field device F2 is enlarged, undergoes a change in shape and is prominently placed on the display unit AE In addition, the smartwatch issues an alarm signal, for example in FIG Shape of an acoustic signal and / or a vibration signal.
Der Bediener erhält dadurch sofort den Hinweis, dass am Feldgerät F2 eine Störung aufgetreten ist und kann sich unmittelbar zu diesem begeben. Um vorab weitere Informationen über die Störung zu erhalten wählt der Bediener das Symbol SY des Feldgeräts F2 aus. Hierfür verwendet er die Krone KR der Smartwatch. Anschließend werden instandhaltungsrelevante Informationen von demThe operator immediately receives the indication that a fault has occurred at the field device F2 and can immediately go to it. In order to obtain further information about the disturbance in advance, the operator selects the symbol SY of the field device F2. For this he uses the crown KR of the smartwatch. Subsequently, maintenance-relevant information from the
Feldgerät F2 abgerufen und auf der Anzeigeeinheit AE der Smartwatch SW angezeigt. Im Falle dass sich der Bediener nicht in der Anlage AN aufhält und die Diagnosemeldungen per Internet abgerufen hat, kann er durch die Auswahl des Symbols SY des Feldgeräts F2 eine dem Feldgerät F2 zugeordnete Stelle, beispielsweise ein Servicetechniker, der sich aktuell in der Anlage AN befindet, informieren. Field device F2 and displayed on the display unit AE of the smartwatch SW. In the event that the operator is not in the system AN and retrieved the diagnostic messages via the Internet, he can by selecting the symbol SY of the field device F2 assigned to the field device F2 body, such as a service technician who is currently in the system AN , inform.
In einer Anlage AN, in der sich eine Vielzahl von Feldgeräten F1 , F2, F3 befinden, kann die Anzeige der den Feldgeräten F1 , F2, F3 zugeordneten Symbolen SY unter Umständen unübersichtlich werden. Die Smartwatch SW bietet daher die Möglichkeit, nur diejenigen Feldgeräte F1, F2, F3 anzuzeigen, welche sich in einer definierten Distanz zu der Smartwatch SW befinden. Es kann hierbei vorgesehen sein, dass die Symbole der Feldgeräte F1 , F2, F3, welche sich außerhalb der Distanz befinden, lediglich ausgeblendet werden. Es kann aber auch vorgesehen sein, erst überhaupt nur die Diagnosemeldungen jener Feldgeräte F1 , F2, F3 abzurufen, welche sich innerhalb der Distanz befinden. Für beide Fälle ist es möglich, sogenannte Permanent-Feldgeräte zu bestimmen, deren Gerätestatus unabhängig von der Distanz des Feldgeräts F1 , F2, F3 zu derIn a system AN, in which there are a plurality of field devices F1, F2, F3, the display of the symbols SY assigned to the field devices F1, F2, F3 may become confusing. The smartwatch SW therefore offers the possibility of displaying only those field devices F1, F2, F3 which are located at a defined distance from the smartwatch SW. It can be provided here that the symbols of the field devices F1, F2, F3, which are located outside the distance, are merely hidden. However, it can also be provided to first retrieve only the diagnostic messages of those field devices F1, F2, F3 which are located within the distance. For both cases, it is possible to determine so-called permanent field devices whose device status is independent of the distance of the field device F1, F2, F3 to the
Smartwatch SW ständig visualisiert wird. Da die Sende-/Empfangseinheit SE der Smartwatch SW unter Umständen eine endliche Funkreichweite aufweist kann es vorgesehen sein, die Distanz an die Funkreichweite der Sende-/Empfangseinheit SE anzupassen. Als Alternative können die Symbole in dem Falle, dass eine Vielzahl von Feldgeräten F1, F2, F3 dargestellt werden soll, als Punkte auf der Smartwatch dargestellt werden. Der Gerätestatus wird hierbei als Farbe dargestellt. Mit steigender Anzahl der Feldgeräte F1 , F2, F3 werden die Punkte kleiner visualisiert. Durch die farbliche Codierung der Gerätestatus ist jedoch ersichtlich, ob es beispielsweise eine Farbe/ein Gerätestatus dominant herausgestellt ist, welche auf den generellen Zustand der Anlage schließen lässt. Smartwatch SW is constantly visualized. Since the transmitting / receiving unit SE of the smartwatch SW may have a finite radio range, it may be provided to adapt the distance to the radio range of the transmitting / receiving unit SE. Alternatively, in the case where a plurality of field devices F1, F2, F3 are to be displayed, the icons may be represented as dots on the smartwatch. The device status is displayed here as a color. As the number of field devices F1, F2, F3 increases, the points are visualized smaller. However, the color coding of the device status indicates whether, for example, a color / device status is dominant, which indicates the general condition of the system.
Zur Bestimmung der Distanz weist die Smartwatch eine Ortungseinheit OE, beispielsweise ein G PS- Modul auf. Die aktuelle Ortsposition wird an den Server SE übermittelt, wobei der Server die Ortsinformation aller Feldgeräte vorhält. Der Server SE sendet anschließend eine Liste aller Feldgeräte F1 , F2, F3 an die Smartwatch, welche sich innerhalb der Distanz befinden. To determine the distance, the smartwatch has a locating unit OE, for example a G PS module. The current location is transmitted to the server SE, the server the Location information of all field devices holds. The server SE then sends a list of all field devices F1, F2, F3 to the smartwatch which are within the distance.
Alternativ bestimmt die Smartwatch die Distanz zu den Feldgeräten F1 , F2, F3 mittels der Sende- /Empfangseinheit über die Signalstärke der ausgesendeten Bluetooth-Telegramme der einzelnen Feldgeräte F1 , F2, F3. Alternatively, the smartwatch determines the distance to the field devices F1, F2, F3 by means of the transmitting / receiving unit via the signal strength of the transmitted Bluetooth telegrams of the individual field devices F1, F2, F3.
Die erfindungsgemäße Smartwatch SW erlaubt es dem Bediener auf einen Blick, den Zustand der Feldgeräte F1 , F2, F3 zu erfassen. Die Schwere des Diagnosefalls, und somit die Dringlichkeit zur Behebung diesen, wird dem Bediener anhand der klassifizierten Gerätestatus angezeigt. Aufgrund der typischerweise geringen Abmessungen der Smartwatch stellt dies ein komfortables Verfahren dar - der Bediener wird nicht am Ausführen seiner typischen alltäglichen Tätigkeiten gehindert. The smartwatch SW according to the invention allows the operator at a glance to detect the status of the field devices F1, F2, F3. The severity of the diagnostic case, and thus the urgency to correct it, is displayed to the operator based on the classified device status. Due to the typically small dimensions of the smartwatch, this is a convenient procedure - the operator is not hindered from carrying out his typical day-to-day activities.
