Description

[0001] The invention relates to an engine with an identification device comprising a storage unit for an identification feature for the engine, wherein the identification feature is stored in the storage unit, and the identification device has an identification control unit configured to transmit the identification feature from the storage unit to a device-internal test interface attached to the engine, and the identification feature is configured to authenticate the engine in the test interface. The invention further relates to a system and a method for identifying an engine.

[0002] Engines with means for their identification are common knowledge. Identification of machines, and especially engines, can be achieved via a nameplate. Such identification serves primarily to ensure the unique identification of the engine. According to DE 10 2006 022 347 A1, an IC tag attachment structure must be provided that reduces the likelihood of the IC tag attached to a vehicle being replaced during repair or maintenance.

[0003] The European Machinery Directive 2006 / 42 / EC, for example, regulates the content of nameplates for machines within the European Union. Nameplates are usually printed or embossed. For example, US 2016 / 0039364 A1 describes an electronic vehicle license plate.

[0004] Other system-specific and, in particular, engine-specific data can also be subject to labeling. For example, in internal combustion engines, performance values ​​can be clearly and visibly recorded on the engine. DE 10 2017 200 068 A1 relates to a control unit, in particular for a motor vehicle, wherein an identification device is provided that has at least one memory that can only be written to once and a communication device connected to the memory for reading the memory, wherein control unit-specific identification data is stored in the memory.

[0005] However, even with other engine types, such as electric motors, additional system-specific identification data beyond the nameplate may be subject to labeling. Identification tools such as emissions labels have also become important engine identification elements; for example, the regulations for emissions labels under the VECC (Vehicle Emission Standard Compliance and Enforcement Program) in China and the EPA (US Environmental Protection Agency) in the USA are well known.

[0006] Such an engine with an identification device can be used in vehicles, particularly land vehicles and watercraft. It is also possible to operate such an engine with an identification device in a stationary manner, particularly for power generation.

[0007] US 2004 / 0024570 A1 describes a method of the type mentioned above for servicing a complex article such as an aircraft, a motor vehicle, or a ship, including retrieving maintenance information relating to the maintenance of a component of the complex article from an electronically accessible tag coupled to the component, and applying the retrieved maintenance information to a determination regarding the maintenance of the complex article. The tag stores computer-accessible information including an identifying identifier of the component and maintenance information describing the maintenance of the component. Tags can store a computer-readable global unique identifier (“GUI”). An interrogator can be used as a reader to read data from tags. In addition, tags can have a user interface. The user interface can be part of the tag or a separate device coupled to the tag.For example, either the tag or a sensor can contain a processor. Processed results can be stored on a tag.

[0008] A general problem is that such markings on an engine with a marking device are relatively complex to change. This means that when changes are made to the engine - particularly when the machine or engine condition changes, for example due to repairs, the installation of new components, or the updating of software in the machine or engine control system - adapting the marking device, in particular the nameplate or an emissions label, is relatively complex and must be carried out by an employee on-site at the machine. For this reason in particular, such marking options still require improvement. It is therefore desirable to improve the marking of machines, and in particular engines, with regard to the problems outlined above.

[0009] This is where the invention comes in. Its object is to provide an improved engine with a marking device and a system. In particular, the marking of the engine is to be improved. In particular, the reliable modification of marking features is to be enabled with relatively little effort.

[0010] According to a first aspect, the present invention relates to a motor according to claim 1 for a mobile system, such as a vehicle or a stationary drive or power system.

[0011] The engine with an identification device of the engine comprises a storage unit for an identification feature for the engine, wherein the identification feature is stored in the storage unit.

[0012] The engine is - a license plate control unit is provided which is designed to transmit the identification feature from the storage unit to an internal test interface which is attached to the engine, and - the identification feature is designed to authenticate the engine in the test interface, whereby - the identification feature can be changed by accessing the storage unit via a license plate communication unit, namely a system interface, and - the test interface can be connected internally to the license plate control unit at the engine location for transmitting the identification feature.

[0013] The invention is based on the consideration that a marking, which in particular depicts the condition of a machine or engine, must be able to be changed with relatively little effort, yet reliably and safely. For example, a machine or engine can assume various construction and configuration states throughout its entire life cycle, but also within a life cycle phase, and therefore a change in the marking may be necessary, e.g., due to a change in engine power or when the engine is resold to another country with different regulations concerning the data set and marking. When engines or machines are manufactured, the country of end user is often not yet known, but different countries have different marking obligations.

[0014] The invention is based on the consideration that this can be achieved with an identification device of the engine comprising a storage unit for an identification feature for the engine in an improved manner compared to a conventional type plate, wherein the identification feature is stored in the storage unit.

[0015] The invention has then recognized that in order to make the marking reliable and secure, the marking device further comprises: a marking control unit which is designed to transmit the marking feature from the storage unit to a device-internal test interface and a marking communication unit.

[0016] According to the invention, on the one hand, the identification feature is designed to authenticate the engine in the test interface. On the other hand, the identification feature can be changed by accessing the memory unit via the license plate communication unit. According to the invention, the test interface can be connected internally to the license plate control unit at the location of the engine for transmitting the identification feature.

[0017] The test interface is a test interface mounted on the engine. The license plate communication unit has a system interface.

[0018] In other words, a motor with an identification device according to the concept of the invention advantageously enables digital identification of the motor by means of an identification device with a test interface.

[0019] The invention has the advantage that a marking feature, in particular an engine marking, can fulfill both a verification function, especially for legislators, and an informational function for both the manufacturer and the user of the machine or engine. For example, the invention enables manufacturers or dealers to quickly adapt the marking to country-specific regulations directly before shipping new products.

[0020] On the other hand, the verification function can enable the unambiguous identification of the engine or machine. Especially for the informational function, it should be ensured that the marking always corresponds to the current condition, in particular the construction, usage, and / or configuration status, of the engine.

[0021] Another advantage is the optimization of space on the engine. If an engine meets several country-specific legal requirements, each of which requires its own markings, the space for applying multiple labels and type plates must be taken into account during design. Digital marking would require only one space for a display, for example, in which any number of valid type plates and labels could be stored, which could be displayed using a "scrolling function."

[0022] By means of the invention, changing an identification feature in an engine with an identification device is thus simplified in general and in particular for the above-mentioned cases.

[0023] In particular, the dependence on manual changes is advantageously reduced, especially the dependence on manual embossing or replacement of nameplates, including attaching, in particular riveting or gluing, a new or modified nameplate on-site to the engine. With an engine according to the concept of the invention with a marking device and a test interface, in such a case, only the marking feature in the marking device needs to be updated. Thus, the change is of a digital, and in particular no longer mechanical, nature.

[0024] A second aspect of the invention relates to a method of claim 8 for marking an engine according to the first aspect of the invention or one of its developments with a marking device. The method according to the invention comprises the steps: - Storing an identification feature in a storage unit; - internal connection of the test interface to the license plate control unit at the engine location for transmission of the identification feature; - transmission of an identification characteristic by a license plate control unit from a storage unit to a test interface internal to the device and attached to the engine or separate from the engine; and - Authentication of the motor in the test interface using the identification feature.

[0025] The process shares the advantages explained above in relation to the engine.

[0026] The method further comprises the step of changing the identification feature (KM) by accessing the memory unit via an identification communication unit, in particular a system interface. It also advantageously enables changes to the engine status that do not require any on-site intervention at the engine, such as updating the engine's control software via remote maintenance, to also eliminate the need for on-site intervention to change the identification feature. This is due to the fact that the identification feature can be changed via an identification communication unit, in particular a system interface, which is connected to the Internet, for example, via suitable telecommunications means. This can save waiting time and costs, particularly labor and travel expenses.Furthermore, for example, due to regional legislation, it may be necessary for an identification feature to be updated to reflect the current design and / or configuration status of the engine before the engine is put into operation. Therefore, in such cases, a motor according to the concept of the invention can shorten the waiting time until commissioning.

[0027] Verifying the marking feature, i.e., authenticating the motor in the test interface, is performed via a display unit and an external test component on the motor. Furthermore, the digitized marking simplifies system-based documentation of the actual marking at the manufacturer. A manually applied label or type plate, with complete documentation, would first have to be photographed and then documented in the production program (e.g., SAP). Digitization allows this step to be performed automatically.

[0028] Also, with an engine having an identification device according to the invention, corrections to an identification feature, for example due to incorrect information provided at the factory, can be made with relatively little effort.

[0029] The test interface can be connected to the license plate control unit within the device at the engine location, thereby enabling transmission of the identification feature, in particular from the storage unit, to the test interface. This advantageously allows for the provision of identification features, in particular those provided in the license plate control unit and / or the storage unit.

[0030] In the engine with the identification device according to the invention, it is provided that the test interface is part of the identification device on the engine and has a display unit. By arranging the test interface as part of the identification device on the engine, the identification feature can be tested directly on the engine. For this purpose, the identification feature can be read out via the test interface and, because the test interface is designed with a display unit, can be read directly from the display unit. In the inventive design of the test interface with the display unit, the identification device corresponds in particular to a digital nameplate on which one or more identification features can be advantageously stored and displayed in a changeable manner.With the inventive design of the test interface with the display unit, no additional reading device or the like is required to check the identification feature.

[0031] In the engine with the marking device according to the invention, it is provided that the test interface has an external test component, namely a radio module and a test plug. This can include the test interface having a radio module such that the marking feature can be tested using a reader compatible with this radio module. Thus, a user or a test officer on-site at the engine can use the reader to read the marking features relating to the engine and provided on the external test component and display them on the reader or a display device connected to the reader for testing purposes. In such a development, no visual contact with the test interface is advantageously required, which can be particularly advantageous for large or inaccessible engines, or engines subject to harsh environmental influences such as dirt or weather.The test interface, as an external test component, also includes a test plug or similar wired test interface. In a further development with the wired test interface, the marking device can be supplied with energy and / or charged during the testing of the marking feature.

[0032] In the engine according to the invention, it is provided that the memory unit is designed to maintain a number of identification features and to make them available to the identification control unit, wherein the identification control unit is designed to select an identification feature from the number according to a received selection command and to transmit it to the test interface. This can include, in particular during manufacture of the engine, a number of identification features being provided and stored in the memory unit that are theoretically required over the entire life cycle of the engine, or at least over a portion of the engine's life cycle. In this way, by means of a selection command, in the event of a change in the state of the engine, for example caused by maintenance or a software update, the identification feature corresponding to this change in state can be selected from the number of identification features.Such a selection can be made automatically via the control unit, for example, during the corresponding software update of the control unit. This advantageously further reduces the effort involved in changing the identification feature.

[0033] In the engine with the identification device according to the invention, it is provided that the identification communication unit has a system interface designed to establish a signal-conducting and / or energy-transmitting connection with a control unit of the engine. This can specifically include the identification device being connectable to the control unit of the engine for energy and / or signal transmission. Via this connection, the identification device can utilize a communication infrastructure of the control unit, whereby the identification device can advantageously be designed simply and, in particular, does not require any means for remote communication. Thus, the transmission of identification features and / or selection commands, and in particular the modification of the identification feature provided at the test interface, can be carried out by the control unit or by remote communication enabled via the control unit.A power-transmitted connection from the control unit to the marking device also has the advantage that the marking device can function independently of other power supply devices, such as a supply unit.

[0034] Advantageous further developments of the invention can be found in the dependent claims and specify in detail advantageous possibilities for realizing the concept explained above within the scope of the task and with regard to further advantages.

[0035] In the engine with the identification device according to the invention, it can be provided that the display unit has an electronic paper display. This can include the display unit having a display, in particular one based on the principle of electrophoresis. An electronic paper display only requires energy when the display content changes, but not when the display shows a constant, i.e., non-changing, content. Thus, an electronic paper display is advantageously suited for the long-term display of identification features—in particular over weeks, days, or years—with little or no energy consumption.

[0036] In the engine with the identification device according to the invention, it can be provided that the identification device has an operating unit with at least one operating element for selecting the display mode of the identification feature. Such an operating unit can be used to switch between different display modes of an identification feature or between different identification features. This is advantageous, for example, if the size of the display unit is not sufficient to display all the data of an identification feature or all the identification features. In general, in a test interface, the currently available display mode or the currently available identification feature can also be changed by operating the operating unit.

[0037] In the engine with the identification device according to the invention, it can be provided that the identification communication unit has a radio interface and / or a wired interface. Communication with the identification device can take place via a radio interface or a wired interface, particularly locally on the engine, in particular for transmitting identification features and / or selection commands, in particular for changing the identification feature provided at the test interface. A wired interface has the advantage that, while a corresponding communication device for transmitting identification features, selection commands, or similar parameters is connected, energy can be transmitted to the identification device at the same time. A radio interface has the advantage that no physical contact with the identification device is required for communication.

[0038] In the engine with the identification device according to the invention, the identification feature can be a type feature, an emissions feature, a configuration feature, or a usage feature. Type features can include, for example, the type number or the engine series. However, a type feature can also be a feature characterizing the individual engine, such as the individual engine number. A feature characterizing the individual engine, in particular, enables unambiguous identification of the engine. The type features thus correspond to the features recorded on a conventional nameplate.

[0039] An emissions characteristic, particularly for an emissions label mentioned above, describes a feature of the engine that is characteristic of its emissions behavior. Such emissions characteristics, particularly for an emissions label mentioned above, can be relevant for emissions approval, which can vary from country to country. Since emissions behavior can change after a change in the engine configuration, particularly the control software, a change to an emissions characteristic, particularly for an emissions label mentioned above, may be necessary after such changes.

[0040] A configuration attribute describes a feature of the engine that is characteristic of its configuration. This includes, in particular, the engine's construction status, i.e., information about the currently installed components. The configuration also includes the current software status, i.e., in particular, the version number of the engine's control software or similar programs relevant to the engine.

[0041] A usage characteristic describes a feature that is characteristic of the use of the engine, for example its operating hours, maintenance cycles and similar usage-relevant features.

[0042] In the engine with the identification device according to the invention, it can be provided that the identification device is partially or completely integrated into a control unit of the engine. In such developments, the equipment complexity is advantageously reduced. In particular, in further developments, the identification control unit—including the identification communication unit—and / or the memory unit can be integrated into the control unit of the engine, and thus only the test interface can be arranged outside the control unit, for example, in the outer region of the engine, in particular on the outside of the engine housing.

[0043] A sufficient degree of tamper protection is advantageous for an engine with the identification device according to the invention, particularly so that identification features cannot be changed in an uncontrolled manner. This is important because otherwise the identification's verification function cannot be fulfilled or can only be fulfilled inadequately. For this purpose, for example, the identification device, and in particular the interfaces for changing the identification feature, can be mechanically shielded against external intrusion. The interfaces for changing the identification feature, in particular the system interface and / or the identification communication unit in general, can also be appropriately secured by software, for example, via suitable encryption and / or authentication.

[0044] Embodiments of the invention will now be described with reference to the drawings. These are not necessarily intended to represent the embodiments to scale; rather, where useful for explanation, the drawings are schematic and / or slightly distorted. With regard to additions to the teachings immediately apparent from the drawings, reference is made to the relevant prior art. It should be noted that various modifications and changes to the form and detail of an embodiment can be made without departing from the general idea of ​​the invention. The general idea of ​​the invention is not limited to the exact form or detail of the preferred embodiments shown and described below, or limited to an object that would be more limited than the object claimed in the claims.For specified design ranges, values ​​within these limits are also intended to be disclosed as limit values ​​and can be used and stressed as required. For the sake of simplicity, the same reference symbols are used below for identical or similar parts or parts with identical or similar functions.

[0045] Further advantages, features and details of the invention will become apparent from the following description of the preferred embodiments and from the drawing, which shows: Fig. 1 an embodiment of a motor with an identification device, in a mobile system, such as a vehicle, or a stationary drive or energy system, according to the concept of the invention, Fig. 2 different points in time during different life cycle phases of an engine according to the concept of the invention.

[0046] Fig. 1 shows a section of an engine 1000 with an identification device 100 according to the concept of the invention. The identification device 100 is designed to display an identification feature KM of the engine 1000. The engine can, for example—not shown here—be installed in a mobile system 2000, such as a vehicle 2001 or a stationary drive or energy system 2002.

[0047] The marking device 100 is arranged in the outer region of the motor 1000, which is only partially shown here. The marking device 100 has a test interface 120. The test interface 120 is embodied here as a display unit 122, specifically as an electronic paper display 124. This technology, also referred to as e-paper, is known from electronic books, so-called e-books, and advantageously includes the fact that the electronic paper display 124 has a relatively low energy requirement and, in particular, only consumes energy when the display content, i.e., the representation on the electronic paper display 124, changes. This technology is therefore particularly suitable for the permanent and long-term display of marking features KM.

[0048] In all embodiments, the test interface also has an external test component 126 in the form of a radio module 128 and a test plug 129.

[0049] In all embodiments, the marking device 100 can be configured to generate various display modes AM of the marking feature KM and provide them at the test interface 120. This can include a marking feature KM having a data set consisting of multiple data items, of which only one date or a limited number of data items are displayed on the display unit 122 at a time. Thus, for example, data that is irrelevant or cannot be displayed on the display unit 122 due to space constraints can be hidden in one display mode AM and instead displayed in another display mode.

[0050] The identification device 100 further comprises a license plate control unit 140, which is connected to the test interface 120 for signal and power transmission. One task of the license plate control unit 140 is to control the test interface 120. For this purpose, one or more display modes AM are generated in the license plate control unit 140 based on the identification feature KM and transmitted to the test interface 120.

[0051] A further task of the license plate control unit 140 is to receive an identification feature KM or to select an identification feature KM from a number KMA of identification features KM according to a received selection command BA. For this purpose, the license plate control unit 140 has a license plate communication unit 150. The license plate communication unit 150 has a system interface 156. The system interface 156 is connected to a display interface 1102 of a control unit 1100 of the engine 1000 via an interface line 1040, transmitting signals and power. Consequently, the identification device 100 can be supplied with power via the system interface 156.In further developments with a system interface 156, the communication infrastructure 1104 of the control unit 1100 can also be used to communicate with the marking device 100, in particular to transmit selection commands BA for controlling the test interface 120 or marking features KM.

[0052] Communication via the system interface 156 by the control unit 1100 has the advantage that the identification device 100 only needs to have one identification communication unit 150, which is configured for local communication with the control unit 1100, and hardware in the identification device 100 for telecommunications, for example via short-range radio or mobile radio, can be reduced or completely eliminated. Power supply via the system interface 156 by the control unit 1100 can further have the advantage that hardware for power supply can be saved and the dependence, for example, on batteries for power supply can be reduced.

[0053] In all further developments, the identification device 100, as shown here, can have further interfaces, such as a radio interface 152 and / or a wired interface 154. A signal-conducting radio connection can be established via the radio interface 152, for example, with a suitable transmitter / receiver module—for example, as part of a service technician's service device (not shown here). A radio connection can be used to transmit, in particular, a selection command BA or system-specific information SI to the control unit 140. Such transmission is also possible via the wired interface 154, via which a service technician's service device can be connected for parameterization—for example, using a suitable connector. The wired interface 154 further has the advantage that a power-transmitting connection can also be established.Thus, in particular when connecting a service device, for example a mobile computer, to change the identification feature KM, the energy required to update the display unit 122 can be obtained from the service device. In particular, with electronic paper displays 124, apart from updating the display unit 122, no energy is required to display the display content, i.e., to display a display mode AM, which advantageously eliminates the need for a power supply, in particular a power supply unit 180, in a further development with a wired interface.

[0054] In this case, the identification device 100 further comprises an operating unit 200 with two operating elements 202. The operating elements 202 are designed as arrow keys. Via the operating unit 200, a user can switch between different display modes AM of the identification device 100 by actuating the operating elements 202. For this purpose, the operating unit 200 is connected to the identification control unit 140 in a signal-conducting manner.

[0055] The identification device 100 also has a storage unit 160. A number KMA of identification features KM can be permanently stored on the storage unit 160. In particular, after delivery and commissioning of the engine 1000, and even during operation of the engine 1000, an identification feature KM from the number KMA can be selected by the identification control unit 140 according to a received selection command BA and displayed to the test interface 120. Such a change in the identification feature KM to be displayed can be caused in particular by a repair, a firmware or controller software update, particularly in the control unit 1100, or a component replacement in the engine 1000. By changing the identification feature KM to be displayed, the identification device 100, and in a figurative sense, in particular a type plate of the engine 1000, can thus be brought into line with the actual condition of the engine 1000.

[0056] The identification device 100 can optionally further comprise a supply unit 180. One task of the supply unit 180 is to supply the identification device 100, and in particular the license plate control unit 140, with electrical energy. For this purpose, the supply unit 180 is connected to the control unit 140 in an energy-transmitting manner. In further developments in which the license plate control unit 140 is connected to the control unit 1100 via a system interface 156, the identification device 100 can be supplied with energy via the control unit 1100. Nevertheless, it may be expedient to provide a supply unit 180, which, for example, has a rechargeable battery as an energy storage device, in order to ensure the functionality of the identification device 100 in the event of an interruption in the power supply.Nevertheless, in particular in further developments with an electronic paper display 124, a supply unit 180 can be dispensed with, since the energy supply is only required during the updating of the identification feature KM and the energy supply in this case can be provided via a wired interface 154 or a system interface 156.

[0057] Fig.2 shows, in a highly simplified manner, various points in time T1, T2, T3, T4, T5, T6 during various life cycle phases P1, P2, P3, P4 of an engine 1000 according to the concept of the invention. During a first life cycle phase P1, the design and development of the engine 1000, a digital model 1006 of the engine 1000 is generated at a first point in time T1 using a CAD system 1510. This digital model 1006 is stored in a system 1500 providing product-specific data, in particular a Product Lifecycle Management (PLM) system 1502. Alternatively or additionally, the digital model 1006 can be stored in an Enterprise Resource Management (ERP) system 1504 (not shown here). Such systems 1500, 1502, 1504 are capable of storing data relevant to an individual engine 1000 and making it available across various life cycle phases P1 to P4 of the engine 1000, in particular for the manufacturer or the user of the engine 1000.

[0058] In addition to mechanical design data, the digital model 1006 can contain further data relevant to the mechatronic system of the engine 1000. This includes, in particular, a parameterization data set IPD for a control unit of the engine 1000. The parameterization data set IPD can contain various parameterization data IP, in particular controller settings, characteristic maps, and similar settings characterizing the operating behavior of the engine 1000. In particular, various parameterization data IP for various operating and configuration states expected in the future operation of the engine 1000 can be stored in the parameterization data set IPD.

[0059] In an engine according to the concept of the invention, a number KMA of identification features KM can now advantageously be stored in the digital model 1006, wherein a corresponding identification feature KM can be stored for each parameterization data item IP.

[0060] During a second life cycle phase P2, the production of the engine 1000, an initial parameterization of a control unit 1100 of the engine 1000 takes place at a second time T2 during the manufacture of the engine 1000 using the parameterization data set IPD and the number KMA of configuration features KM. For this purpose, the parameterization data set IPD and the number KMA of configuration features KM can be loaded from the system 1500 providing product-specific data.

[0061] During a third life cycle phase P3, the commissioning of the engine 1000, the control unit 1100 is parameterized at a third time T3, for example to set a configuration of the engine 1000 desired by the customer. For this purpose, for example, a production employee PM can select the parameterization data IP in the control unit 1100 corresponding to the desired configuration. In all further developments, the control unit 1100 can be designed, upon receipt of a parameterization data IP, to transmit a selection command BA corresponding to this parameterization data IP to the identification control unit 140 (not shown here) of the identification device 100, so that the identification feature KM matching the parameterization data IP is selected from the number KMA of identification features KM and made available at the test interface 120.In this case, a first parameterization data item IP1 is selected in control unit 1100, whereupon control unit 1100 transmits a selection command BA1 matching the first parameterization data item IP1 to the license plate control unit 140 (not shown here), causing the latter to provide a first identification feature KM1 at test interface 120. The engine 1000 can be commissioned at the manufacturer's or customer's premises, or at the site of use. The setting made by the production employee PM can also be documented in the product-specific data-providing system 1500.

[0062] During a fourth life cycle phase P4, the operating phase of the engine 1000, a change to the configuration of the engine 1000 occurs at a fourth time T4, for example, initiated by the customer. Since the change is exclusively a software change, for example the selection of a different controller setting or a different characteristic map, the configuration change can be made by a service employee SM via an internet connection IV by remote maintenance. For the change, a second parameterization data item IP2 is selected via remote access in the control unit 1100, whereupon the control unit 1100 causes the license plate control unit 140 (not shown here) to provide a second identification feature MK2 at the test interface 120 via a second selection command BA2. The change made by the service employee SM can also be documented in the system 1500 that provides product-specific data.

[0063] In addition to the possibility of only selecting parameterization data IP or identification features KM previously stored in the control unit 1100 or in the memory unit 160 of the identification device 100 by remote access via a selection command BA, all embodiments can also be designed such that new parameterization data IP or new identification features KM can be transmitted to the control unit 1100 or to the identification device 100 by remote access, in particular via an Internet connection IV.

[0064] At a fifth time T5 during the operating phase of the engine 1000, an on-site visit is carried out by the service employee SM. During this visit, the structural status of the engine 1000 is changed, for example, by installing a new component. For this purpose, the service technician connects to the control unit 1100 using a mobile computer, for example, and selects a third parameterization data item IP3 in the control unit 1100, whereupon a third selection command BA3 is transmitted to the identification device 100. Accordingly, a third identification feature KM3 is provided at the test interface 120. Alternatively, the selection command BA3 can also be transmitted directly to the identification device 100, for example, by the service employee SM connecting directly to the identification device 100 via an interface 152, 154 (not shown here).The change made by the service employee SM can also be transmitted, in particular via an Internet connection IV, to the system 1500 providing product-specific data and documented there.

[0065] At a sixth time T6 during the operating phase of the engine 1000, the current identification feature KM3 is checked, i.e., the engine 1000 is authenticated in the test interface 120. This can be done routinely by operating personnel BM—or, in accordance with legal requirements, by an external test representative. For the check, the operating personnel BM reads the identification feature KM3 from the test interface 120, which in this case has a display unit 122. Alternatively or additionally, the identification device 100 can have an external test component 126 via which authentication can be performed.

[0066] At a further point in time T7 not explicitly shown here, it may be necessary to change a stored identification feature or add another identification feature, for example to correct an error or, for example, following legal innovations and / or changes. According to a preferred embodiment, this could now be done via remote access. Within the scope of the concept of the invention, in particular "tamper-proof" remote access is possible. Such remote access, in particular "tamper-proof" remote access, enables, for example, an adaptation of stored data by the manufacturer. This can be done within the scope of or prior to remote access, in particular "tamper-proof" remote access, in coordination with or taking into account the requirements of one or more legislators.
