[0001] Description

[0002] Method for detecting at least one installation action in an industrial plant

[0003] The present invention relates to a method for detecting at least one installation action in an industrial plant. Furthermore, the invention relates to a connection element, a computer program, and a device for this purpose.

[0004] State of the art

[0005] It is well known from the state of the art that industrial automation systems often require numerous individual installation steps for installation and maintenance. Incorrect performance of even just a few of these installation steps can severely impair the functionality of the system. At the same time, such errors are difficult to trace. Subsequent diagnosis and inspection are often associated with considerable effort and high costs.

[0006] A solution for general diagnostics in automation systems is known, for example, from document DE 102021 108770 A1. To monitor the function of an IO-Link system, diagnostic data can be recorded about the current state of an infrastructure component, e.g., its input voltage, its output current, energy transfer efficiency, the component's own temperature, signal quality, and / or similar, or about the state of the infrastructure component's environment, e.g., vibrations, ambient temperature, humidity, inclination, and / or similar.

[0007] Further generic solutions are also known from the documents DE 1020 15109482 A1 and DE 102013 100987 A1.

[0008] Disclosure of the invention

[0009] It is therefore an object of the present invention to at least partially remedy the disadvantages described above. In particular, it is an object of the present invention to propose an improved and automatable solution for monitoring installation processes. The subject matter of the invention is a method having the features of claim 1, a connection element having the features of claim 10, a computer program having the features of claim 14, and a device having the features of claim 15. Further features and details of the invention emerge from the respective subclaims, the description, and the drawings.Features and details that are described in connection with the method according to the invention naturally also apply in connection with the connection element according to the invention, the computer program according to the invention and the device according to the invention, and vice versa, so that a mutual reference is always possible with regard to the disclosure of the invention.

[0010] The invention particularly relates to a method for detecting, and preferably for monitoring and / or diagnosing, at least one installation action in an industrial system. The system can be embodied as an electrical machine and / or an industrial automation system.

[0011] The system can further comprise, for example, pneumatic and / or hydraulic and / or fluid power and / or electrical and / or mechanical components. A system comprising pneumatic components is, for example, a pneumatic conveyor system that transports materials from one location to another. A system with hydraulic components can be, for example, a hydraulic press. A system with fluid power components is, for example, a cooling system that uses liquids to cool machines. If electrical components are provided, the system can be, for example, an automation system that includes one or more electric motors and / or an electrical control system and / or robots, for example to transport and / or hold and / or process and / or assemble materials / products. A system with mechanical components is, for example, a mechanical press or a system with at least one gripping device or the like.The industrial automation system can also include a combination of the above. For example, the system is designed as a robot system that automatically transports, processes, or assembles materials.

[0012] It is possible for the system to provide a connection of system components in the field by one or more connection elements, in particular modules and / or terminal boxes, and / or via one or more connecting means, preferably cables and / or connectors. The connecting means can be used for energy and / or signal and / or data exchange. The connecting elements can have multiple ports to which the components can be connected via the connecting means. The connections between components, connection elements and connecting means can collectively serve to provide automation functions of the system. The design or structure of the connections can be described using a system topology.

[0013] The method according to the invention may comprise the following steps, which are preferably carried out successively in the specified order and / or repeatedly and / or automatically:

[0014] Determining vibration data, preferably digital vibration data, wherein the vibration data results from a sensory detection of at least one of the one or more connection elements and / or at least one of the one or more connecting means,

[0015] Evaluating the vibration data, wherein the vibration data are examined for a signature which is specific to the at least one installation action in the system,

[0016] Identifying at least one installation action based on the evaluation.

[0017] This has the advantage that not only a general diagnosis is possible, but specific installation actions on the system can be identified and, if necessary, diagnosed.

[0018] In order to be able to determine the vibration data and / or perform the sensory detection, at least one sensor, preferably a vibration sensor, can be provided in the one or more connection elements, preferably modules, and / or on the one or more connecting means, preferably cables and / or connectors. The sensor / vibration sensor can thus detect / measure vibrations and output the vibration data, which can represent the detected vibrations and / or provide the measured values. In this way, it is possible, for example, to detect rattling in the one or more connection elements.

[0019] By evaluating the vibration data, it can be determined whether the installation process was carried out correctly, e.g., whether an "IP67-compliant" plug was screwed into a connection. The sensor / vibration sensor thus detects the connection / screwing in. Installation processes can be detected and classified, particularly based on the vibrations. The connection elements, preferably modules, are designed, for example, as I / O-Link master modules. The invention is based in particular on the finding that tools used to perform installation processes, such as a torque wrench when tightening, cause vibration. The same applies, for example, to plugging in and screwing in connections.

[0020] The integration of a sensor, preferably a vibration sensor, into the connection element(s) has the advantage that the connection elements can be used decentrally in the field of the system, and the installation activities can thus be monitored decentrally in the system where they are carried out. The connection elements can serve as interfaces between the various components of the system, such as sensors and actuators, and at least one decentralized or centralized control device, such as a PLC in the field. The connection elements can be designed, for example, as IO-Link modules and / or as fieldbus modules, each with IP67 protection if necessary. The connection elements can also primarily serve to connect the components to a control device. In addition, the connection elements can be designed as specialized modules such as IO-Link hubs and / or analog converters, the latter, for example, for the integration of analog sensors and actuators.Furthermore, it is possible for the connection elements to be designed as functional modules, which have extended functionality to support installation and commissioning.

[0021] Within the scope of the invention, a connection element, preferably a module, can refer to a distributor and / or a connection module, which serves for the decentralized interconnection of components such as actuators, sensors, and machines in the system. The distributor can be designed as a fieldbus module, which is connected via a fieldbus to at least one decentralized automation platform or central control device such as a PLC (programmable logic controller).

[0022] If a connection element is designed as a fieldbus module, it advantageously enables communication between at least one control device and the components connected to the connection element using a fieldbus protocol such as PROFIBUS, PROFINET, CANopen, or EtherCAT. Multiple components can be connected to the connection element, possibly also via IO-Link, and in particular, to control and / or read the components based on / by means of a received fieldbus signal.

[0023] Another possible variant of a connection element can also directly transmit an electrical control signal and / or sensor signal between the central control device and at least one component. Furthermore, the connection element can be designed as an I / O module, in which the connected components are connected to the control device via the connection element not only via a fieldbus, but also via digital or analog inputs and outputs.

[0024] More generally, the connection element preferably serves as an interface between at least one control device and the components connected to the connection element, such as sensors, actuators, and machines. It can convert and process signals from the control device into signals usable by the components, and vice versa. The inputs and outputs enable the transmission of process data to provide the functionality of the system.

[0025] The connection element can also be designed as an IO-Link module. This means that communication between the connection element, preferably a module, and the components connected to it takes place via the IO-Link standard. IO-Link enables digital communication with the components and offers a high degree of flexibility when connecting components from different manufacturers. The connection element can be designed as an IO-Link master or IO-Link device, thus enabling easy integration of IO-Link components into the decentralized circuitry of the system. Furthermore, the connection element can have a fieldbus interface (and therefore also be designed as a fieldbus module), for example to enable control commands and / or communication via a fieldbus with a control device and / or other connection elements, preferably modules, and / or decentralized automation platforms.

[0026] Optionally, it can be provided that the respective connection element, preferably module, has a plurality of lighting means, preferably LEDs, which are each assigned to a connection, preferably port, or several connections, preferably ports, of the connection element and are optionally operated to indicate an operating state of the respective connection(s).

[0027] The vibration data is preferably determined based on sensor detection. Various sensors can be used for this purpose, such as a vibration and / or fiber optic sensor on the connecting means, in particular a cable, and / or on the connecting element, in particular a module. The connecting means and / or the connecting element can have a transmission line for transmitting energy and / or data and / or signals, in particular for transmission between components of the system. Furthermore, a sensor system for sensor detection can be integrated into the connecting means and / or the connecting element and / or the transmission line, preferably to provide sensor-supported monitoring of the connecting means and / or the connecting element and / or the transmission line.

[0028] In order to provide the integrated sensor technology, it can be provided that the transmission line is designed as a fiber optic transmission line and a sensor element is arranged in the region of the transmission line. Alternatively or additionally, the sensor element itself can be designed as a fiber optic element. This makes it possible to provide the sensor detection as a fiber optic-based detection. A fiber optic cable - used as a sensor technology - can provide a high level of sensitivity and accuracy in order to measure, for example, vibration and / or temperature and / or current and / or voltage and / or noise and / or humidity and / or stretching and / or bending and / or length, preferably cable length, and / or pressure. In this way, for example, errors and / or anomalies and / or damage to the system can be determined through sensor detection.The action and / or installation information can then point to one of these errors and / or anomalies and / or damages including the corresponding location of the action, e.g. the location of the error.

[0029] Furthermore, it is possible that the topology of the system can also be determined based on the sensor detection, particularly based on the cable lengths determined by the detection. Knowledge of the topology can then be used, if necessary, in the detection and / or diagnosis of at least one installation action.

[0030] According to a further advantage, the industrial plant can be designed as an industrial automation plant, in which at least some of the components are designed as devices that comprise at least actuators and / or sensors to provide automation functions of the plant. This can have the advantage that the industrial plant enables the provision of efficient automation functions.

[0031] Furthermore, the components and in particular devices can be connected to the connection elements via the connecting means, in particular cables, in order to be controlled and / or evaluated via the connection by at least one control device. The at least one control device comprises, for example, precisely one central and / or several decentralized control devices. It is conceivable that the control devices are provided at least partially outside the connection elements. Alternatively or additionally, it is conceivable that the or at least one of the control devices is integrated into at least one of the connection elements. Furthermore, it is possible for one or more groups of components, preferably devices, each comprising a plurality of components / devices, to be connected to a common one of the connection elements via the connecting means. In other words, the components / devices can be divided into groups.The components / devices of a common group are then assigned to a common connection element and connected to it. Other groups or their components / devices can be connected to other common connection elements accordingly.

[0032] This enables the components / devices of a group to be connected decentrally in the field of the system, and in particular via the corresponding connection element as a distributor, to the (at least or exactly one) control device for control and / or evaluation for data and / or signal exchange. In this way, the automation functions of the system can be reliably provided. Optionally, the components / devices of at least one of the groups can be connected to their common connection element, preferably in a star configuration, and preferably connected to a fieldbus system via the common connection element.

[0033] Furthermore, it is possible for the at least one installation action to comprise establishing at least one of the connections between the components, preferably devices, and the connecting elements. This provides the advantage that the method according to the invention can monitor and, in particular, diagnose these installation actions, which are essential for the operation of the system. This can significantly simplify installation and maintenance, especially with such a complex system structure.

[0034] It may be advantageous if, within the scope of the invention, the connecting element or at least one of the connecting elements itself comprises the control device in order to automate at least part of the entire system.

[0035] Preferably, the or one of the connection elements can be designed as a decentralized automation platform, which, together with the other automation platforms, provides the automation of the system in a decentralized manner in the system.

[0036] Preferably, the plurality of connection elements can each be configured as a decentralized automation platform. The connection elements can then jointly and decentrally provide the automation of the system. The at least one installation action can comprise a mechanical and / or electrical installation of the at least one automation platform.

[0037] For example, it can be provided that during the recognition at least one of the following types and / or results of the installation action is distinguished, preferably by classifying the installation action based on the signature: establishing a plug connection on the connection element,

[0038] Inserting at least one of the connecting means into a connection, preferably a port of the connecting element,

[0039] Fixing the connecting element by turning or snapping it into place,

[0040] Completeness of engagement,

[0041] Completeness of rotation, successful completion of the installation operation, type or marking of the connecting means, incompleteness of the installation operation, completeness of the installation operation, compatibility of the connecting means and the connection,

[0042] Use of a tool and / or type of tool used to fix and preferably tighten the fastener.

[0043] The signature can, for example, be a pattern that can be recognized in the vibration data and is specific to at least one of the aforementioned types and / or results. For this purpose, a pattern recognition algorithm can be used during the evaluation.

[0044] It is conceivable that, when evaluating the vibration data, an examination of the vibration data with regard to the signature is carried out, wherein the examination preferably comprises the use of a pattern recognition algorithm and / or a machine learning algorithm. Providing the pattern recognition algorithm and / or the machine learning algorithm can comprise the following steps: 1. Collecting a sufficient training data set comprising a sufficient number of signatures to ensure accurate recognition. 2. Preparing the training data through preprocessing, such as removing background noise and scaling the signatures to a uniform size. 3. Selecting and applying a suitable pattern recognition algorithm and / or a machine learning algorithm to analyze and classify the signatures. 4.Validate the algorithm by testing it on a separate dataset to confirm its accuracy and reliability. An example artificial neural network that can be used for such classification is a convolutional neural network (CNN). The CNN configuration can include various layers, such as convolutional layers, pooling layers, fully connected layers, and dropout layers. The number of layers and their parameters can vary depending on the application. The CNN can be reliably used to classify vibration data.

[0045] Preferably, within the scope of the invention, it can be provided that, upon detection, an environmental event in the environment of the connection element and / or connecting means in the system is detected based on the evaluation, wherein for this purpose, the vibration data are preferably examined during the evaluation with regard to a further signature that is specific to the environmental event. In this case, at least one of the following types of environmental events can preferably be distinguished: an error during operation, maintenance and / or installation and / or commissioning of the system, an external influence, damage and / or the presence of a user. This makes it possible to carry out a comprehensive diagnosis of the installation process, also based on an environmental event.

[0046] A further advantage can be achieved within the scope of the invention if a result of the detection, preferably the detected installation action, and preferably a type and / or result of the installation action and / or a successful completion of the installation action and / or an environmental event, are automatically documented in system documentation. The documentation can be automated, and the system documentation can be provided by a digital data storage device. This enables reliable storage of relevant information about an installation, which can be used at a later time for system testing and / or maintenance.

[0047] It is also conceivable that the vibration data are recorded during installation and / or maintenance and / or during ongoing operation of the system in order to be evaluated as needed and / or after completion of the installation and / or maintenance in order to check the system and / or installation activities. In this way, relevant information about a system can be reliably stored and used at a later date for the inspection and / or maintenance of the system. Preferably, it can be provided that the vibration data is evaluated while the installation activity is being carried out. A result of the detection can be issued to a user in order to assist the user in carrying out the installation activity and in particular to signal the correct completion of the installation activity. For example, a light source such as an LED can be coloured in a specific colour (e.g.red) at the connection if the result indicates an error, preferably an incorrect connection element that was detected based on the vibration data. The light can also light up in a different color, such as green, if the installation process was completed successfully. The result of the detection can also be signaled by a flashing pattern or other colors, for example to indicate errors or statuses. Another possible output is a display and / or an audio output, e.g. speech, each for example directly on the connection element or on a separate device such as a tablet. Optionally, it is conceivable that an alarm is issued to a user based on the detection.

[0048] The invention also relates to a connection element, in particular in the form of a module, preferably a fieldbus module and / or IO-Link master, for connecting components of an industrial system in the field. The connection element can have one or more connections, in particular ports, in order to connect at least one connecting means for connecting the connection element to at least one of the components. Furthermore, the connection element can have a sensor, preferably a vibration sensor, and / or a sensor interface to a sensor, preferably a vibration sensor, in order to provide sensory detection of vibrations on and / or in an environment of the connection element. The connection element according to the invention thus brings with it the same advantages as have been described in detail with reference to a method according to the invention.In addition, the connecting element can be suitable for use in a method according to the invention.

[0049] It may optionally be possible for a further connection to be provided for communication with at least one decentralized and / or centralized control device in order to carry out signal and / or data transmission to the one or more connections, preferably ports, for the connected components on the basis of the communication, preferably fieldbus communication, and in particular to transmit vibration data resulting from the sensor detection. For example, it is possible for the vibration data to be evaluated not in the connection element, but in the control device. Accordingly, the vibration data for this purpose can initially be transmitted to the control device via the further connection. A further possibility is for the control device to control and / or evaluate the components and thus the signal and / or data transmission to the respective connection takes place on the basis of the communication.The connection element can serve as an intermediary for this purpose. The connection element can therefore loop the communication from the control device to the component via the corresponding connection or evaluate the communication with the control device beforehand. The latter allows a signal and / or data transmission to be initiated with the component based on this evaluation. The connection element can thus also function as an adapter for different communication technologies.

[0050] According to a further possibility, an interface, preferably a bus or IO-Link, radio interface, or wired interface, can be provided to transmit vibration data resulting from sensor detection. This also makes it possible for the evaluation of the vibration data to be performed in an external data processing device rather than in the connection element. For this purpose, the external data processing device can receive the vibration data via the interface.

[0051] Furthermore, it is conceivable for the connection element to be designed as a master for a communication system for digital point-to-point communication, in particular as a 10-link master. In this way, the connection element can be connected via at least one of the ports, in particular in the form of a 10-link port, to at least one of the components, in particular each in the form of an IO-Link device, for a bidirectional data connection. This makes it possible to provide at least one automation function of the system via the data connection.

[0052] Furthermore, it is conceivable for a housing of the connection element to be made of a waterproof material and / or to have a seal to ensure a waterproof seal. The housing can be designed to protect electronics within the housing against the ingress of water and dust. The connection element can have at least one connection designed for connection to a, preferably central, control device, in particular via an Ethernet, Profibus, ProfiNET, EtherCAT, or CAN bus. This has the advantage of ensuring reliable and fast data transmission between the connection element and the control device. The use of a waterproof housing and / or a seal also achieves a high protection class that protects the connection element from environmental influences such as moisture and dust.This enables the connection element to be used reliably in the field and outside of a control cabinet in the system.

[0053] Furthermore, it is possible for the connection element to have a data storage device, preferably a non-volatile data storage device, for temporarily storing and / or non-volatilely storing vibration data resulting from the sensor detection. This allows for subsequent evaluation and / or documentation.

[0054] Furthermore, it is conceivable that the connecting element itself has a data processing device, preferably according to the invention, in order to carry out at least part of the evaluation of the vibration data itself.

[0055] It can further be advantageous for the connection element to be designed as a decentralized automation platform. The connection element can have a control device such as an industrial PC in order to provide automation of the system in a decentralized manner and preferably with further automation platforms in the field of the system. In this case, the one or more decentralized automation platforms can preferably be connected to a common central controller. Furthermore, the connection element can be suitable for being connected to several function modules, which can be modularly supplemented to provide automation functions. For this purpose, the function modules can comprise, for example, a motor control and / or a power supply for actuators of the system. The function modules can also have a power supply and / or a fieldbus interface.

[0056] It can be provided that a connection element, preferably a module, is connected to at least one of the components via a communication system for digital, and in particular point-to-point, communication. A concrete example of such a communication system is IO-Link. IO-Link refers to a communication system for connecting intelligent sensors and actuators to an automation system, which is standardized in the IEC 61131-9 standard under the designation Single-drop digital communication interface for small sensors and actuators (SDCI).

[0057] The communication system comprises, for example, a master, in particular an IO-Link master, and one or more devices, for example sensors or actuators, which are suitable for communication with the master. These can specifically be IO-Link devices. The master provides in particular the interface to the higher-level controller, i.e. a control device, preferably a central control device such as a PLC, and controls communication with the connected devices. The master can have one or more connections, preferably ports, in particular IO-Link ports, to which only one device can be connected at a time. This can also be a hub which, as a concentrator, enables the connection of conventional switching sensors and actuators.

[0058] The device, especially an IO-Link device, can be an (intelligent) sensor, actuator, hub, or, due to the bidirectional communication, a mechatronic component, such as a gripper or a power supply with IO-Link connection.

[0059] The communication system can provide point-to-point communication between the master and the devices. The communication system thus enables a direct connection between the master and the devices, without the need for mediation by other systems. This ensures fast and reliable communication, especially fieldbus-independent.

[0060] Cables and / or connectors according to standards such as M12, M8, or M5, as well as three-wire cables, can be used as connecting devices. This can have the advantage of ensuring quick and easy installation of the sensors and actuators. The connecting devices can be connected using a bayonet or screw connection, for example.

[0061] The invention also relates to a data processing device comprising means for carrying out the steps of the method according to the invention. Thus, the device according to the invention offers the same advantages as those described in detail with reference to a method according to the invention.

[0062] The invention also relates to a computer program, in particular a computer program product, comprising instructions which, when executed by a computer, cause the computer to carry out the method according to the invention. The computer program according to the invention thus provides the same advantages as have been described in detail with reference to a method according to the invention. Furthermore, the computer program can be at least partially non-volatile and / or available as software for download and / or as a cloud service and / or as an executable program and / or as a configuration file and / or as a program library and / or as source code and / or in compiled and / or encrypted and / or compressed form and / or in a combination thereof.

[0063] A data processing device, for example the device according to the invention, which executes the computer program can be provided as the computer. The computer can have at least one processor for executing the computer program. A non-volatile data memory can also be provided, in which the computer program is stored and from which the computer program can be read by the processor for execution.

[0064] It is also conceivable for the computer to comprise at least one integrated circuit such as a microprocessor, an application-specific integrated circuit (ASIC), an application-specific standard product (ASSP), a digital signal processor (DSP), a field-programmable gate array (FPGA), or the like. The computer may further comprise at least one interface for data exchange, e.g., an Ethernet interface, an interface for a LAN (local area network), a WLAN (wireless local area network), a system-on-a-chip (SoC), or another wireless interface such as Bluetooth or near-field communication (NFC). Furthermore, the computer may be configured as one or more control units, i.e., as a system of control units. The computer may, for example, also be provided in a cloud and / or as a server in order to provide data processing for a local application via the interface.It is also possible that the computer is designed as a mobile device, such as a smartphone.

[0065] The invention may also provide a computer-readable storage medium comprising the computer program according to the invention. The storage medium is designed, for example, as a data storage device such as a hard disk and / or a non-volatile memory and / or a memory card. The storage medium can, for example, be integrated into the computer.

[0066] Furthermore, the method according to the invention can also be implemented as a computer-implemented method. Furthermore, only individual steps of the method can be computer-implemented. In other words, each individual step of the method can optionally be performed automatically and / or computer-implemented.

[0067] Further advantages, features, and details of the invention will become apparent from the following description, which describes embodiments of the invention in detail with reference to the drawings. The features mentioned in the claims and in the description may be essential to the invention individually or in any combination. They show:

[0068] Fig. 1 is a schematic representation of parts of a connecting element according to embodiments of the invention.

[0070] Fig. 4 is a schematic representation of parts of a connecting element according to embodiments of the invention.

[0071] Figs. 1 and 4 schematically show an exemplary connection element 10. In the illustrated embodiment of the invention, the connection element 10 is provided in the form of a module 10. The module 10 can be designed, for example, as a fieldbus module 11 and / or an IO-Link master 12. More generally, the connection element 10 serves to connect components 80 of an industrial system 1 in the field.

[0072] The connection element 10 can have one or more connections 30, in particular ports 30. These serve to connect at least one connecting means 90 to each of the connectors 10 to at least one of the components 80. In this way, the respective component 80 can be connected to the connection element 10 via the corresponding connection 30 for data and / or signal exchange. Furthermore, it is shown that optional lighting means 20 can be provided on the connection element.

[0073] Furthermore, the connection element 10 can have a sensor 50, preferably a vibration sensor 50, and / or a sensor interface 75 to a sensor 50, preferably a vibration sensor 50. This can provide sensory detection of vibrations on and / or in the surroundings of the connection element 10. This enables an evaluation of the vibration data, in which the vibration data is examined for a signature specific to at least one installation action. In this way, the at least one installation action can be identified based on the evaluation.

[0074] The installation action can, for example, be an action performed by a worker to connect at least one of the components 80 to at least one of the terminals 30 of the connection element 10. Thus, the installation action can, for example, involve connecting / plugging / tightening the connecting means 90. For installation and / or maintenance of the system 1, a plurality of such installation actions are often provided in order to establish a topology of the system 1.

[0075] Fig. 2 shows a topology of the system 1 in further detail. The system 1 can be designed as an electrical machine and / or an industrial system. Examples of such an industrial and in particular electrical system 1 are an automation system such as an electrical control system, an electrical measurement and control system, an electrical drive system or a conveyor and / or production system. The industrial system 1 can further be a hydraulic or pneumatic or fluid or mechanical system 1. In the system 1, liquids or gases can be transported through pipes or valves, a coolant can be supplied, or mechanical forces can be exerted on an object in order to provide a desired automation function, in an automated manner.Further examples of such systems 1 are a hydraulic press, a pneumatic conveyor system, a fluid cooling system or a mechanical manufacturing machine.

[0076] According to Fig. 2, the industrial plant 1 can be designed as an industrial automation plant 1, in which at least some of the components 80 are designed as devices 81, 82 that comprise at least actuators 81 and / or sensors 82 to provide automation functions of the plant 1. The devices 81, 82 can be connected to the connection elements 10 via the connecting means 90, in particular cables 90, in order to be controlled and / or evaluated via the connection by at least one control device 2. The control device 2 can be designed as a central control device 2', which is connected to several of the connection elements 10 in order to centrally control and / or evaluate the components 80 connected to the connection elements 10.

[0077] It can be seen in Fig. 2 that one or more groups of devices 81, 82, each comprising a plurality of devices 81, 82, are each connected via the connecting means 90 to a common one of the connection elements 10. This makes it possible for the devices 81, 81 to be connected decentrally in the field of the system 1, and in particular via the corresponding connection element 10 as a distributor, to the control device 2 for control and / or evaluation for data and / or signal exchange. The devices 81, 82 of at least one of the groups can be connected to their common connection element 10, preferably in a star shape, and preferably connected to a fieldbus system 8 via the common connection element 10.

[0078] It is further illustrated that at least some of the connection elements 10 can be configured as a fieldbus module 11 and / or as a master module / IO-Link master 12. For the IO-Link master 12, the devices 80 can be partially configured as corresponding IO-Link devices 13.

[0079] In addition, Fig. 2 shows a connecting element 95, in particular a T-piece, for connecting more than one component 80 to a connection 30 of the connection element 10. Fig. 1 further shows that a further connection 25 can be provided for communication with at least one decentralized and / or centralized control device 2 in order to carry out a signal and / or data transmission to the one or more connections 30, preferably ports 30, for the connected components 80 on the basis of the communication, preferably fieldbus communication, and in particular to transmit vibration data resulting from the sensory detection. In addition, an interface 35, preferably a bus or IO-Link or radio interface or wired interface, can be provided to transmit vibration data resulting from the sensory detection.

[0080] The connection element may further comprise a data memory 28, preferably a non-volatile data memory, for temporarily storing and / or non-volatilely storing vibration data resulting from the sensory detection.

[0081] Fig. 3 illustrates, according to embodiments of the invention, a method 100 for detecting at least one installation action in an industrial plant 1. In the plant 1, as illustrated in Fig. 2, a connection of components 80 of the plant 1 in the field can be provided by one or more connection elements 10, in particular modules 10, as well as by one or more connecting means 90.

[0082] According to a first method step 101, vibration data can be determined. The vibration data can result from sensor detection of at least one of the one or more connection elements 10 and / or at least one of the one or more connecting means 90. For this purpose, a sensor 50, such as a vibration sensor 50, can be provided in the one or more connection elements 10 and / or in the one or more connecting means 90.

[0083] According to a second method step 102, the vibration data can be evaluated. The vibration data can be examined for a signature that is specific to the at least one installation action in system 1.

[0084] According to a third method step 103, recognition of the at least one installation action may be provided based on the evaluation 102. This makes it possible, for example, to qualitatively evaluate and / or diagnose the installation action, i.e., to detect an error in the installation action, such as incomplete execution and / or damage.

[0085] The integration of a sensor 50 and preferably a vibration sensor 50 into the one or more connection elements 10 and / or into the one or more connecting means 90 makes it possible to detect and evaluate vibrations directly at the respective connection element 10 or connecting means 90. This allows, for example, installation actions on the connection element 10 to be recognized and evaluated (e.g., "Was it screwed in to IP67 standards?"). Examples include screwing and connecting screws and / or connectors by rotating them and / or inserting them into the terminals of the connection element 10, tightening screws, or the correct use of a torque wrench. These installation actions generate noise and vibrations that can be detected by the sensor / vibration sensor 50.

[0086] The above explanation of the embodiments describes the present invention exclusively by way of examples. Of course, individual features of the embodiments can be freely combined with one another, provided they are technically feasible, without departing from the scope of the present invention.
