Description

Method for operating a connection module

Technical area

The present invention relates generally to the field of planning and assembly of machines such as automation systems, and in particular to the operation of a connection module in a computer-aided installation of such a machine.

background

The complexity and variety of automation systems that need to be developed, planned, installed, maintained and repaired is constantly increasing. In all phases of the life cycle of such a system, such as development/planning, production, commissioning, operation and maintenance, efficient and effective support for an installer or planner through comprehensive and, above all, complete documentation is becoming increasingly important. However, the documentation available in practice, for example in the form of circuit diagrams, does not always meet this requirement, as installation activities are not recorded sufficiently or completely due to poorly coordinated work processes or the use of poorly coordinated documentation tools. These well-known circumstances inevitably lead to gaps in the system documentation, which makes reliable maintenance or repair of a system difficult or, in the worst case, impossible.

It is an object of the present invention to at least reduce disadvantages of the prior art with regard to the installation of machines. In particular, it is an object on which the invention is based to provide a computer-aided method and a system in order to enable a simpler, faster, safer and error-free installation of electrical components and thereby at least partially overcome the above-mentioned disadvantages of the prior art overcome.

Description of the invention

The above task is solved by a method, a connection module, a computer program and a device for data processing according to the independent patent claims. Further features and details of the invention emerge from the respective subclaims, the description and the drawings. The subject of the invention is in particular a, preferably computer-implemented, method for operating a connection module in a computer-aided installation of a machine, in particular a system. The connection module can be designed for a decentralized and modular connection of components of the machine. For the installation of the machine, it can be provided that several connection modules are arranged in a spatially decentralized manner. The method can therefore also be provided for the computer-aided, in particular electrical, installation of several spatially decentralized connection modules and/or the components of the machine to be connected thereto.

The machine can be designed as at least one of the following machines:

An automation system, A production plant,

- A logistics facility,

- A production line,

- A machining center,

An industrial robot,

A production facility, an aggregate, an electrical device.

In particular, the machine can be designed as a machine with a modular character or as a mobile or movable machine in which individual parts of the machine are installed modularly according to an installation specification. This installation is carried out at least partially manually by a user such as a worker.

The connection module can be an electrical connection module, which makes it possible to interconnect the components of the machine in a decentralized manner. Furthermore, the connection module can be connected to a control device such as a PLC so that the control device can control the components connected to the connection module in operating mode and thus enable operation of the machine. The control device can also be connected to several other, decentralized connection modules in order to also control the connected components of the machine. In this way, a decentralized Interconnection of the components is provided via the connection modules to the control device.

Furthermore, a connection module can preferably have a plurality of connection points, with a component being connected to each of the connection points and thus being connected to the connection module. For example, a connection module can have at least two or at least four or at least eight or at least 10 connection points. A display element can each be assigned to the connection points. It is also possible for the connection points to have multiple pins in order to transmit electrical signals to the component and/or receive them from the component. It is possible for an operating current to be provided for the component and/or data to be exchanged with the component in this way. It is also possible that components such as actuators or sensors themselves do not have an interface to a bus system, but the connection module can be controlled via the bus system to control and/or read out a component via the connection point.

The components are preferably designed as electrical components, each of which can perform a task for the operation of the machine. For example, the components can comprise installation elements, such as cables or the like, in order to electrically connect an actuator and/or a sensor and/or another component to the connection module. The components can also comprise at least one component and/or at least one sensor and/or at least one actuator. A connection module can also be referred to as a component. It is also conceivable that connection modules are interconnected, for example in the structure of a master-slave connection. The components can therefore also comprise further connection modules. In this case, for example, one can speak of a module-module or module-hub-point connection. The connection modules can accordingly also comprise a hub. It is also possible for the connection modules to comprise master modules and slave modules, so that a master-slave connection can be possible. The connection modules can enable a decentralized and modular connection of the components such as the installation elements.

Decentralized can refer to the fact that the connection modules at least partially replace a central control cabinet, in that the connection modules only provide a portion of the connections for the machine, but enable these connections to be made decentrally in the field. In a central topology, for example a In the case of a centralized control cabinet concept, a point-to-point connection is referred to in particular, ie the starting point, the connection and the end point are clearly defined. In contrast, in decentralized applications it is possible, or can often even be necessary, to arrange or connect several components between the starting point and the end point.

In principle, the following components can be provided for a machine: devices such as actuators and/or sensors, the connection modules, installation elements, for example for cabling.

The method according to the invention can comprise the following steps, which are preferably carried out one after the other or in any order, whereby the steps can also be carried out repeatedly and/or automatically and/or provided for further connection modules of the machine:

Providing an installation function of the connection module for the installation of the machine, preferably individual components, wherein the installation function can initiate a, preferably optical, output of installation information to support the establishment of the connection of the components,

Providing an operating function of the connection module for operation of the installed machine, wherein the operating function can initiate an electrical output to the connected components, preferably to the components which are properly connected to the connection module,

Initiating an installation mode on the connection module, disabling the operational function and enabling the installation function.

In other words, in the installation mode, the operation function can be automatically deactivated and the installation function activated to provide the connection establishment support for the installation instead of the electrical output for the operation of the installed machine. The connection module itself can thus help to support a user in installing the machine and thus make the installation easier and safer. For this purpose, the method steps can be carried out at least partially or completely by the connection module itself, e.g. B. through firmware of the connection module. Initiating the installation mode (and the associated deactivation or activation of the functions) can triggered from outside, e.g. B. by an installation device such as a mobile computer with software to support and guide the user during installation. Triggering can e.g. B. be possible through a data and/or electrical connection of the installation device to the connection module. Triggering can also be provided through a connection to the power supply, so that a separate data connection is not necessarily required for this.

The installation function can be intended as a support function for establishing the connection and thus for the installation. A further support function for the installation can be a check function, which checks whether the connection has been established completely and/or in accordance with an installation specification.

For example, it is possible that the test function in a test mode of the connection module detects the presence of an error such as an installation and/or connection error. For this purpose, the test mode and the test function can be initiated automatically or manually after the connection of the component to the connection module has been established. The error can be, for example, connecting the correct component to the wrong connection point or connecting the wrong component to the correct connection point. It is therefore possible that a user in the form of an actuator incorrectly connects the component to a connection point of the connection module which is incorrectly designed as an input and not (as it should be) as an output. It is also possible that a user in the form of a sensor incorrectly connects the component to a connection point of the connection module which is incorrectly designed as an output and not (as it should be) as an input. It is also conceivable that the user connects such a component to a connection point which is not intended for this connection point according to the installation specifications. It is also conceivable that the connection is incomplete mechanically and/or electrically. In these cases, the connection, i.e. the connection of the component to the connection module, can represent an error that can be detected by the test function. To do this, the test function can advantageously initiate a signal and/or data exchange with the component via the connection point in order to determine which component is connected to the connection point. For example, the component sends information such as a designation about its identity to the connection module. The connection module can then transmit this information to an installation device if necessary so that the information is compared with the installation specification. If, based on the If the error is detected during calibration, this can be communicated to a user via the test function through the optical output. For this purpose, a colored output can be provided via at least one display element as an optical output, e.g. in red, yellow and green or other colors. The optical output can therefore be used in test mode to display a result of the detection and thus the test.

It is conceivable that the test mode is initiated automatically after the installation mode when the connection of the component to the connection module has been established. In this way, the test function can be activated automatically after the connection has been established. For example, the initiation of the test mode can be triggered by a user acknowledging that the connection has been established and thus that the installation action has been carried out, e.g. by a user input. This user input can be made, for example, on a computer such as the installation device and/or by an input device such as a touchscreen and/or an electronic item of clothing such as a glove.

It is also possible for the test function to detect a deviation from the installation specification, in particular a different connection of a component to the connection module, preferably to a different connection point. It can then be provided that the different connection is documented in the installation specification and/or the connection module is reconfigured based on the detected deviation. If, for example, the user has incorrectly connected an actuator to an input as a connection point, this can be determined by the test function and the input can be reconfigured into an output or hybrid connection on the connection module. In other words, after the deviation has been detected, the connection point can be reconfigured using software while maintaining the physical connection.

The optical output can be used to output installation information in installation mode. Furthermore, the optical output can serve to provide the operating function in an operating mode of the connection module. For example, in operating mode - for example after a complete check and error-free machine, the optical output can represent a current signal status of an assigned connection point. The signal status refers to a status of the electrical output and preferably indicates whether the electrical output is currently present via the connection point. The signal status can be in the operating mode (in particular exclusively) via a Define control device. It is also possible for the control device to receive diagnostic messages from the connection module in the event of an error. To represent the signal status, a display element can e.g. B. light up in different colors, e.g. B. in red, yellow, and green. In the installation mode, however, it can be provided that the connection point, preferably the pins at the connection point, do not carry an electrical signal. The respective display element can then show where the component, e.g. B. a connecting element such as a connector should be connected. Preferably, it can already be seen from the optical output by the display elements that the connection module is in installation mode (e.g. by flashing or different colors).

By switching to an installation mode, the advantage can also be achieved that a link between the optical output and the electrical output can be used flexibly. It is also possible that additional installation functions are made available via the optical output in installation and/or test mode. Some installation functions are given below as examples. For example, free connection points for connecting to a component can be shown via the optical output. It is also conceivable that the connection point used for the connection is then automatically documented accordingly, e.g. in the installation specification. In addition, the connected component such as a device, e.g. an actuator or sensor, can be automatically recognized in test mode. Based on this recognition, connection points can be reassigned if necessary and this documented accordingly, e.g. in the installation specification. It is also possible that components do not have to be permanently connected to the connection point provided for them in accordance with the installation specification, but if the connection deviates from this, this can be subsequently adjusted in the installation specification depending on the recognition. The respective installation function can be provided at least partially by an installation device which is in data communication with the connection module.

Within the scope of the invention it can be provided that the connection module has at least one display element in order to provide a display for the operating function. The at least one display element can be assigned to a connection point of the connection module for the connection to a respective component to be connected. The display element is, for example, an electrical component such as a light-emitting diode. Furthermore, the method, in particular for establishing the connection of the components in installation mode, can be as follows Step include: Initiating activation of the display element by the installation function to output the installation information in order to display the connection point for the respective component to be connected. The installation information can thus be support and/or installation instructions to point out to a user which connection point the component to be connected should be connected to.

Of further advantage, it can be provided that the initiation of the activation of the display element is based on the following steps in order to initiate the output of the installation information based on a received identifier and an installation specification:

Providing the, in particular digital, installation specification, which specifies an assignment of the connection module and other spatially decentralized connection modules of the machine with the components,

Receiving the, in particular digital, identifier of the respective component to be connected, wherein the component is designed in the form of an installation element, preferably a cable or a component, or another component, wherein the identifier is preferably received by a detection device which has previously read in a physically present identification means such as a machine-readable code and has generated the identifier on the basis of the read-in identification means,

Identifying the component to be connected and/or the connection module assigned to the connection based on the installation specification provided, preferably by querying the electrical component and/or the connection module from the installation specification using the identifier, preferably from a list and/or database of the installation specification.

The at least one piece of installation information can then be output based on the received identifier and the identified component and/or the identified connection module, wherein the output preferably comprises a visual and/or acoustic output to a user. The method thus enables a simpler, faster and error-free assignment of connection modules to components and/or vice versa and can therefore provide a user with significant support in installing the machine and simplify the process. Furthermore, in this way, a support system for installation, in particular for cabling, can be spatial be provided directly on the identified component for the user's guided orientation, in which an installation device can, if necessary, carry out the method steps automatically. The installation device, in particular a data processing device according to the invention, can advantageously communicate with individual connection modules and thus enable the installation information to be output. For this purpose, the installation device can have at least one interface for communication.

In a further possibility, it can be provided that the method further comprises the following step: providing a test function for checking the establishment of the connection and/or a function of the components and/or the operating function and/or a connection state of the connection, preferably the test function initiates the electrical output to the respective connected component. The test function can e.g. B. be provided in a test mode of the connection module. This means that the connection module can have three different modes: an operating mode in the sense of a productive phase, an installation mode in the sense of an installation phase and a test mode in the sense of a test phase or “IO check phase”. The test function can e.g. B. include activation of the ports of the connection points even without a connection to a control device in order to enable an elementary functional test of the associated component. For example, it is checked whether a sensor is connected to the input and/or an actuator to the output. A result of the test can be shown in the optical output, e.g. B. be output via a display element. For example, colors like red can indicate an error.

It can also be advantageous if, within the scope of the invention, the method includes the following further step: determining a connection state between the connection module and the component in order to determine whether the connection has been established. For this purpose, for example, an electrical connection test can be carried out, through which it can be automatically determined whether the connection module and the component have an electrically conductive connection. Depending on the design, it is conceivable that a circuit is not immediately closed upon connection, especially if the installation has not yet been completed. Therefore, additional or alternative options for determining the connection status can also be provided. Thus, determining the connection state may further include: receiving an installation message based on input from the user and/or from the connection module. The installation message received can indicate that the connection of the Connection module was established with the component, preferably with a indicated connection point. Accordingly, it can be checked that the connection point that was displayed was actually connected to the component. It is possible that by detecting the establishment of the connection, e.g. B. documentation is triggered by a manual acknowledgment of a user and/or an automatic acknowledgment by detecting the connection, for example if both sides of a cable have been connected. For example, installation documentation is stored in the documentation. This documentation can be carried out repeatedly if necessary, e.g. B. every time an activity is acknowledged in order to successively build up the documentation of the installation. In order to make the installation information visible to the user on the one hand and to be able to document the work carried out on the component on the other hand, it is advantageous that an installation device can communicate with the connection modules. Following the installation and/or documentation, the control device can optionally be programmed and/or the connection modules can be configured based on the documentation. Due to this circumstance, it may be possible that the connection module does not know beforehand what task it has to carry out in the future machine. This can also be referred to as “unconfigured”.

A further advantage within the scope of the invention can be achieved if the operating function initiates the electrical output in the form of an output of an electrical current and/or an electrical voltage to the components. The electrical output can be provided at connection points of the connection module for connecting the components in order to operate the components connected to the connection points. This has the advantage that the connection module enables electrical interconnection of components in the operating mode.

It is also advantageous if the deactivation of the operating function is carried out in order to prevent the component to be connected from being operated during installation. In this case, the electrical current and/or the electrical voltage at the respective connection point can at least be reduced in installation mode, in particular in such a way or to such an extent that the operation of the corresponding component is prevented or reduced to a safe level. This has the advantage that the component is not operated inadvertently during installation. It is possible that this reduction can be dispensed with in operating mode. Furthermore, within the scope of the invention, it can be provided that after completion of the installation, the installation mode is exited and an operating mode is initiated for providing the operating function. In this way, the regular function of the connection module can be provided.

Advantageously, the invention can provide that the connection module has at least one display element to provide an indication of the operating function. The display element comprises, for example, a light source such as a light-emitting diode or the like. It is also possible for the display element to have exactly two lighting states (on and off), with a lighting mode adapting these lighting states in terms of frequency and/or color if necessary. Furthermore, the display element can be arranged on a housing of the connection module in such a way that the display element is visible from the outside to a user. The at least one display element can be assigned to at least one connection point of the connection module, e.g. by being arranged on the housing adjacent to the connection point. It is also possible for the display element to light up in a different lighting mode in the operating mode, such as a different color and/or a different flashing frequency and/or a different brightness than in the installation mode. The operating mode and/or the operating function can thus be clearly signaled and visually separated from the installation mode or the installation function. A function can be provided in the operating mode to repeatedly detect errors and to display the error, such as a broken cable, using the display element. In installation mode and/or test mode, this function may not be used, but instead the display element can be used for another function, in particular for the installation and/or test function.

Furthermore, it can be provided that the electrical output at connection points of the connection module is provided for connecting the components. In this case, the electrical output at the connection points in the operating mode can be defined by a control device outside the connection module, preferably a PLC. In the installation mode, however, the electrical output at the connection points can be defined by an installation device outside the connection module and the control device. Preferably, a functional connection to the control device for controlling the components via the connection points is active and/or configured in the operating mode and inactive and/or unconfigured in the installation mode. It is also optionally conceivable that the installation mode is signaled by at least one display element of the connection module in order to visibly distinguish the installation mode from the operating mode using the at least one display element. For this purpose, a different lighting mode is used, for example.

It is also advantageous if the components comprise at least one connecting element and/or a cable and/or a component and/or an actuator and/or a sensor and/or another connecting module. For example, the components can be designed as actuators and/or sensors which are operated in the operating mode by the electrical output. The actuator can be, for example, a motor or the like.

It can optionally be provided that an initiation of an activation of a display element of the connection module by the installation function for outputting the installation information is and/or is synchronized with an output of further installation information in the form of an installation instruction to support a user during the installation. The output of further installation information can include at least one of the following steps:

Initiating a display of a connection point, in particular a slot, of the electrical component for the installation element on a user interface of a computer, wherein the user interface visualizes a digital twin of at least a part of the machine, and preferably visualizes a mechanical and/or an electrical structure of the part of the machine,

Initiating a display of a connection point, in particular a slot, of the electrical component for the installation element using augmented reality and/or using a piece of clothing such as a glove and/or using a detection device and/or using an optical and/or acoustic signal,

Initiating an output of the installation instructions as an instruction for the user to connect the installation element to a specific connection point of the electrical component, the connection point preferably being determined based on the installation specification,

Initiating an acoustic output, in particular a voice output, of the installation instructions. This enables the user to be informed directly by the installation instructions as to how the component should be connected, ie connected to the connection module. For example, the connection point to which the component is to be connected can be indicated by the display element lighting up. Furthermore, lighting up the display element can make it possible to display a correctly or incorrectly assigned connection point accordingly. For this purpose, the connection module can have several of the display elements, which are assigned to corresponding connection points, e.g. B. by an adjacent arrangement on a connection element.

It is conceivable that the installation information is output by means of an optical and/or acoustic and/or mechanical signal and/or by means of a vibration. For example, it can be provided that in installation mode and/or in test mode the installation and/or test function determines that a component is connected to the wrong connection point. This can be signaled by the installation information if necessary. In the same way, a correct connection can be signaled alternatively or additionally. The installation information can, for example, be binary information (e.g. correct connection or incorrect connection). The installation information can also include further information if necessary, e.g. an indication of which connection point would be the correct one according to the installation specifications. For this purpose, text information and/or a graphic can also be output, for example. The installation information can also be displayed on a screen accordingly. It is also conceivable that the installation information is output via a vibration or the like, e.g. via an item of clothing such as a glove worn by the user. It is particularly advantageous if the detection device is integrated into this item of clothing in order to scan an identifier through it.

The invention also relates to a connection module for a decentralized and modular connection of components of a machine, the connection module being designed to carry out the steps of a method according to the invention. The connection module 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.

A user can be, for example, an installer and/or plant mechanic and/or electrician and/or worker and/or planner and/or mechanical designer or developer and/or electrical designer or developer and/or PLC programmer and/or Commissioning engineer and/or maintenance engineer and/or machine operator. It is possible for the user to use the method according to the invention by making the method available to the user via a computer. For this purpose, a computer program can be executed at least partially by the computer and/or by the connection module and/or another computer in order to carry out the method steps according to the invention.

Furthermore, it is possible for several users to use the method according to the invention simultaneously or at least partially at the same time. Accordingly, the steps of a method according to the invention can also be carried out multiple times and/or at least partially in parallel, preferably for different connection modules. For example, the steps are at least partially carried out simultaneously for at least two or at least three or at least four users.

Several components such as installation elements can be provided for the installation of the machine. Each of these components can be assigned an identifier by which the components can be uniquely identified. The identifier can be information that can be processed digitally, for example. The respective component can have the identifier in that a physical identification means is provided and/or attached to the component. The components can be, for example, cables or components that are a functional part of the machine. The identifier advantageously comprises a unique and in particular one-to-one identifier. This makes it possible to clearly identify the component using the identifier in connection with the machine and/or other machines and/or the installation of the machine. One or more pieces of information about the component can be assigned to the identifier. The at least one piece of information can comprise at least one of the following pieces of information: at least one piece of status information, the output installation information, an identifier of the identified connection module, at least one of the documentation specifications described in more detail below, such as component type, machine type, system type, user, connection point designation, time stamp date and time, installation duration, address in a bus system, equipment identification, cable length, port assignment, properties of the open cable, temperature, humidity, current project status during assembly, plan deviation and reason. A digital storage of the at least one piece of information associated with the identifier thus makes it possible to create a digital twin of the component. In this way, passive smartification of the component can be enabled. Smartification is understood in particular as the addition of intelligent properties to an industrial product such as a component and/or a part and/or an installation element such as a cable. Information technology can be used to enable connection modules to process data and offer additional added value. Passive smartification can be provided as a corresponding preliminary stage using a passive intelligent component such as an NFC chip (near field communication, abbreviated to NFC) and/or a machine-readable code. This can create a basis for automated recording or for changes and their effects on the function of a machine. The clear, preferably one-to-one identification in conjunction with access to an external database can enable the active enrichment of information and thus passive smartification.

In particular, machine devices such as actuators and/or sensors are operated via the installation elements, i.e. preferably controlled and/or read out. To operate the devices, a control device such as a PLC (programmable logic controller) can be provided, which can carry out the electrical operation of the devices via the installation elements and connection modules. For this purpose, the control device can be in electrical connection with the connection modules.

Preferably, the installation element can comprise a cable and/or a component, wherein the cable can have at least or exactly one plug connector, and can preferably be assembled on one side, i.e. has a female or male plug on one side and an open end on the other side. Alternatively, the cable can also be assembled on two sides, i.e. the cable has a female or male plug on each side.

It may further be possible for the at least one piece of installation information to include installation instructions to support a user such as a worker and/or installer during installation. The installation instructions can also include instructions for installation, for example step-by-step instructions.

The connection point, in particular a connection port, which can be provided according to the installation specification for connecting the component with the received identifier, can, for example, via the received identifier from the Installation specification can be queried. For this purpose, the installation specification can enable an electronic query, e.g. B. by means of a database and/or a list and/or the like.

The display of the connection point on the user interface can, for example, include a graphical representation of the connection points of the component, whereby the connection point which is intended for connecting the component with the received identifier is graphically highlighted.

The user interface can be a graphical user interface which is displayed on a screen, preferably of an installation device such as a computer. The computer can be, for example, a portable computer such as a laptop or tablet.

The display using augmented reality can be done, for example, by using VR (virtual reality) glasses by a user to display additional information and/or by recording the user's surroundings using a camera and that Camera image is processed to incorporate additional information into the camera image. The additional information includes e.g. B. highlighting the connection point if the physical connection point of the connection module can be seen in the camera image.

Furthermore, an acoustic output can also be provided, which includes, for example, controlling a loudspeaker. The acoustic output can, for example, be a voice output through which the connection designation of the connection point is spoken.

A further advantage within the scope of the invention can be achieved if the method comprises the following further steps:

Verifying the connection, preferably the connected connection point, based on the installation specification, preferably a specified, digital circuit and in particular electrical connection plan, in particular to determine whether a user has correctly implemented the installation information in the form of installation instructions, wherein preferably depending on the verification, a label for the installation specification is stored, and particularly preferably in the case of a positive verification, the following step is carried out:

Identify the connection point as a correctly connected connection point in the installation specification. Advantageously, verification can be carried out based on the determination of the connection status. Verification thus makes it possible to assess whether the user has correctly followed the installation instructions. The result of the verification can be used to store the marking in the installation specification. The installation specification can thus be used at a later point in time to check whether the installation specification was followed and/or to what extent the installation deviated from the installation specification.

If a user deviates from the installation instructions, this often happens for a relevant reason or cause. Therefore, a user can be provided with the option of entering an installation parameter, for example via the user interface and/or an input device such as voice input and/or a keyboard and/or a mouse and/or an electronic item of clothing and/or a touchscreen. Advantageously, in the event of a negative verification, i.e. if the user has not correctly implemented the installation instructions, at least one of the following steps can be carried out: storing an identification of the connection point as a changed connected connection point in the installation specification, preferably based on an installation parameter entered by the user, in particular a reason or cause for the change, wherein preferably an indication of the cause or cause of the change is also stored, and preferably: initiating a correction of the connection in accordance with the installation specification. The correction can, for example, comprise an adjustment of the installation specification if the new connection is justified and thus contributes advantageously to the desired installation.

Optionally, the method may further comprise the following further step, which step is preferably carried out when verifying the connection:

Validating the, in particular verified, connection with regard to complete establishment of the connection, in particular a proper screw connection and/or power and/or data connection and/or contacting, preferably by means of a measurement variable transmitted by an external test means, in particular a sensor or a test tool, to determine whether a user has adhered to a specified metric. This makes it possible to advantageously ensure the valid or necessary requirements for materials used or the connection depending on an installation environment. This also has the advantage that safety risks when installing machines are significantly reduced. The specified measurement variable can be a reference value, which is compared with the transmitted measurement variable as the current measurement value. The establishment of the connection can, for example, be considered correct and/or complete if the transmitted measurement quantity meets a predefined condition such as exceeding the reference value.

Furthermore, it can be provided that the at least one piece of installation information comprises installation instructions to support a user in rebuilding the machine, wherein the initiation of the output preferably comprises at least the following step: initiating an output of an installation sequence using the at least one piece of installation information for installing the machine. The installation information can, for example, comprise installation instructions which also specify an installation sequence. This simplifies installation for a user and speeds up installation, since a complex interpretation of a circuit diagram and in particular a connection plan is at least partially no longer necessary.

According to an advantageous development of the invention, it can be provided that initiating the output includes initiating bidirectional communication with the identified connection module via a bus system. The output can e.g. B. can be triggered by a specific message, preferably a command, being transmitted to the connection module via communication. For this purpose, for example, a computer program can be executed by a data processing device, the data processing device being connected to the bus system.

Advantageously, the invention can provide that at least one of the following specifications is received, preferably by the installation message, in order to create a digital twin of the connection module and/or the electrical component based on the received identifier and the identified connection module: component type, machine type, System type, user, connection point designation, time stamp, date and time, installation duration, address in a bus system, equipment identification, cable length, port assignment, properties of the open cable, temperature, humidity, current project status during installation, Deviation from plan and reason. Within the scope of this invention, the at least one specification can also be referred to as a documentation specification.

The installation message can e.g. B. may have been generated based on an input from a user, whereby the user may have specified at least one specification in the input. It is also possible for the specification to be determined automatically, e.g. B. by the component and/or a data processing device, in particular based on the received identifier. For this purpose, for example, the at least one specification can be stored in the component and/or in the installation element and/or in the connection module.

In a further possibility, it can be provided that the installation information includes an installation configuration and/or installation documentation, preferably for dismantling and/or rebuilding the machine, which is stored for documentation, preferably stored in a data storage and/or transmitted to the electrical component becomes. The data storage can be designed as a non-volatile data storage in order to reliably enable later evaluation of the installation configuration and/or the installation documentation. The installation configuration and/or the installation documentation can include, for example, the stored identification based on the verification.

A further advantage can be achieved within the scope of the invention if the installation information comprises a unique identifier which identifies the component and/or the installation element and/or the identified connection module, wherein the installation information is preferably included in the installation specification, in particular in a digitized construction plan ECAD and/or MCAD data is stored, and/or wherein the component is selected from a plurality of similar components based on the identifier and/or the identified connection module is selected from a plurality of similar connection modules. The installation specification thus makes it possible to query the association of the connection modules with the components based on the identifier and/or the identifier. For this purpose, the installation specification can include a link between the identifiers and/or with the identifiers. The identifier can optionally be uniquely assigned to one of the identifiers of the components and/or the identifier can correspond to this identifier. A further advantage within the scope of the invention can be achieved if the installation specification includes a predefined specification for a modular and/or decentralized structure of the machine, in particular of the system, preferably based on predetermined ECAD and/or MCAD data, in particular via an interconnection the components such as installation elements in the form of cables and/or components by means of the connection modules, preferably comprising an electrical connection plan, wherein the installation specification is preferably determined by linking the ECAD and MCAD data. The installation specification can therefore include a digital circuit diagram and/or construction plan and/or installation plan of the machine.

In addition, it is conceivable within the scope of the invention that a configuration of the connection module is carried out on the basis of the identifier in order to transfer the connection modules from a basic configured state, in which the component is preferably configured for bidirectional communication by means of a bus system and/or functional control by a control device, preferably a PLC, is excluded, to a state with an extended configuration for functional control by the control device.

The received identifier makes it possible, in particular, to recognize which installation element has been connected (or is to be connected) to the connection module. This detection can be used to automatically configure the connection modules necessary for the installation, which significantly reduces the configuration effort on a connection module during installation. For example, based on the received identifier and the installation specification, it is determined which of the connection modules is (or will be) connected to the installation element. The connection module can be configured accordingly for this installation element, so that for later functional control by the control device, it is known to the control device that the installation element is connected to this connection module. This allows the control device e.g. B. to operate at least one device of the machine such as an actuator and/or sensor via this connection module and/or the installation element.

The invention can also provide a system for computer-aided

Installation of spatially decentralized electrical components of a machine, comprising a detection device, in particular a scanner such as a Hand scanner or a camera, for providing an identifier of an installation element, preferably a cable or a component, further comprising at least one electrical component, preferably in the form of a connection module for connection to the installation element and further installation elements, and a device for data processing, comprising means for carrying out the steps of a method according to the invention.

In addition, a device for data processing, preferably for the connection module, comprising means for carrying out the steps of a method according to the invention, can also be the subject of the invention. The device can be adapted to communicate with the components, in particular modules of the machine, in particular system, preferably without the modules being preconfigured and/or connected to a control device.

Furthermore, it can be provided that the identifier is coded in a machine-readable code assigned to the installation element, in particular arranged on it, the machine-readable code being machine-readable by means of the detection device.

In addition, it is possible for the connection module and/or the components and a computer and/or a control device to be connected to one another via a bus system for bidirectional communication, wherein the bidirectional communication is provided based on a communication protocol for a fieldbus system, in particular based on a ProfiNet, Ethernet/IP, EtherCAT or 802.3 standard, and/or bidirectional communication is provided wired via a bus system or wirelessly via Bluetooth or WLAN, based on a standard in accordance with IEEE 802.11 or based on a mobile telecommunications standard.

The invention also relates to a computer program comprising instructions which, when the program is executed by a computer such as the data processing device according to the invention, preferably the connection module, cause the computer to carry out the steps of a method according to the invention. The computer program according to the invention thus brings with it the same advantages as those described in detail with reference to a method according to the invention. The computer program can be implemented as a firmware of the connection module.

It can be provided that several users carry out the (same) method steps simultaneously and/or at least partially at the same time. The simultaneous and/or at least partially simultaneous execution of (same) process steps by several users is also referred to below as a multi-user application.

A further method for a computer-aided installation of spatially decentralized electrical components such as connection modules of a machine can also be the subject of the invention, in which the installation is carried out by at least two users simultaneously and/or at least partially at the same time.

In connection with a method according to the invention, in particular in a multi-user application and/or in the further method, a handover between the different users can be provided. In order to enable a handover between the, preferably both, users and to ensure an optimal process, a processing status of the respective user can be digitally documented automatically and in real time. In this way, the two or more users can work on different areas of the machine at the same time without endangering the integrity of the electrical installation or having to carry out lengthy coordination processes.

It is advantageous that the current status of the installation is displayed in real time. Furthermore, installation instructions can be assigned to the respective user and documented digitally. In this way, relevant information can be collected during the installation process. The information collected includes, for example:

■ A user-specific identifier and role (access and editing permissions, qualification level if applicable), and/or

■ A last used fastener and/or a last used component and/or a last used component, and/or

■ A last processed location, in particular a segment, of the machine to which the last used connection module and/or component and/or the last used component was attached, and/or

■ A last user (unique user ID) and the time of the last edit by the user, and/or; A last identified fastener, preferably a scanned component, and a machine area for which the fastener or component is intended.

It can be provided that at least two users carry out the installation of spatially decentralized electrical components, preferably connection modules, of a machine. Each user can log in via the user interface of a computer, preferably a portable computer, and then select, for example, a work order to be processed in order to begin the installation.

Description of the embodiments

Planning, installing and setting up machines and electronic automation technology is a complex task. This applies to centralized control cabinet systems as well as to decentralized systems in which control modules are attached directly to the systems. The corresponding processes are carried out by different people, such as system planners, electrical planners, installers, System programmers, etc. A special feature of decentralized systems is the distribution of modules at different points on a machine compared to centralized control cabinet systems. Particularly with larger machines, simultaneous installation, i.e. installation carried out by several users at the same time, can be advantageous for time and logistical reasons. To enable a smooth installation process, the work status should be documented digitally automatically, individually for each user and in real time. For various reasons (such as maintenance planning, system diagnostics), it is important to have complete documentation of all relevant information throughout the entire system life cycle.

In Fig. 1, a central interconnection by means of a control cabinet 9 is shown schematically in order to contrast this with a decentralized interconnection by means of spatially decentrally arranged electrical connection modules 4 of a machine 1 in Fig. 2. Instead of connecting all devices 5 such as sensors and actuators directly to the control cabinet 9 as shown in FIG. 1, several connection modules 4 can be used in the decentralized connection in FIG. 2. Like the control cabinet 9, these enable the devices 5 to be coupled to a control device 8 such as a PLC. However, the connection modules 4 can be provided in a decentralized and distributed manner in the vicinity of the devices 5. The connection modules 4 thus only partially interconnect the devices 5, with the connection modules 4 together or, for example, one and/or more connection modules 4 each carrying out the entire interconnection via one and/or more hubs 6. In order to enable the connection modules 4 to be configured and/or controlled centrally, a master module 3 can be connected upstream of several of the individual connection modules 4. It is also possible for the interconnection to be further subdivided using at least one hub 6.

In Fig. 3, parts of a system 2 according to embodiments of the invention are shown, which can be provided for a computer-aided installation of spatially decentrally arranged electrical connection modules 4 of a machine 1. The system 2 can comprise a detection device 22, in particular a scanner 22 or a camera 22, for providing an identifier 11 of an installation element 10, preferably a cable 11 or a component 11. Furthermore, the system 2 can have at least one electrical connection module 4 for connection to the installation element 10 and other installation elements 10. A device 30 for data processing can also be part of the system 2, wherein this data processing device 30 Means for carrying out the steps of a method 100 according to embodiments of the invention.

The identifier 11 can be encoded in a machine-readable code 12 assigned to the installation element 10, in particular arranged on it, wherein the machine-readable code 12 is designed to be machine-readable by means of the detection device 22. It is thus possible for a user to scan the code 12 by means of the detection device 22 and thus to transmit the identifier 11 to the data processing device 30.

Furthermore, the connection modules 4 and at least one computer 30, 31 and/or a control device 8 can each be connected to one another via a bus system 21 for bidirectional communication, wherein the bidirectional communication can be provided based on a communication protocol for a fieldbus system, in particular based on a ProfiNet -, Ethernet/IP or 802.3 standards, and/or bidirectional communication can be provided wired via a bus system 21 or wirelessly via Bluetooth or WLAN, based on a standard according to IEEE 802.11 or based on a mobile telecommunications standard. In order to enable operation of the connection modules 4, the connection module 4 can also be connected to a power supply 13.

Furthermore, a computer program 20 is shown, which includes instructions which, when the program is executed by a computer 30, cause the computer 30 to carry out the steps of the method 100 according to exemplary embodiments of the invention.

In Fig. 4 and 5, method steps of the method 100 are visualized according to embodiments. Specifically, Fig. 5 shows a method 100 for operating a connection module 4 in a computer-aided installation of a machine 1. The connection module 4 can be designed for a decentralized and modular connection of components - such as the installation elements 10 - of the machine 1. According to a first method step 101, provision of an installation function of the connection module 4 for the installation of the machine 1 can be provided, wherein the installation function initiates an output of installation information to support the establishment of the connection of the components. The output of the installation information can include initiating an optical output. Subsequently, according to a second method step 102, provision of a An operating function of the connection module 4 can be provided for operating the installed machine 1, the operating function initiating an electrical output to the connected components. Then, according to a third method step 103, an installation mode can be initiated in the connection module 4, the operating function being deactivated and the installation function being activated. After the connection has been established, it is also possible that, according to a fourth method step 104, a test mode is initiated in which a test function is carried out to check that the connection has been established correctly.

The method 100 may also provide at least one of the following support options:

Supporting the user during installation, especially cabling, preferably through the installation function and/or through a testing function

Support the user in documenting the installation,

Supporting the user in testing/automated testing, preferably the output of installation information,

Assistance to the user during disassembly,

Support engineering in planning,

PLC programmer support.

Initiating the optical output can include initiating activation of a display element 41 shown in FIG. 3 on the electrical component 4 in order to display a connection point 42, in particular a slot 42, for the installation element 10 to be connected in the installation mode through the display element 41. Alternatively or additionally, initiating the output can include initiating a display of a connection point 42, in particular a slot 42, of the connection module 4 for the installation element 10 on a user interface 32 of a computer 31. The user interface 32 can visualize a digital twin of at least part of the machine 1, and preferably a mechanical and/or an electrical structure of the part of the machine 1. Further alternatives or additional options for output include a display of a connection point 42, in particular a slot 42, of the connection module 4 for the installation element 10 using augmented reality and/or an output of the installation instructions as an instruction for the user to connect the installation element 10 to a specific connection point 42 of the connection module 4, the connection point 42 preferably being determined based on the installation specification 200. In addition, an acoustic output of the installation instructions can also be provided so that a user can follow the installation instructions without seeing the computer 31. Here z. B. an identifier of the connection module 4 and / or the corresponding connection point 42 is output verbally.

It is also possible that the installation information includes an installation configuration and/or installation documentation, which is stored in a data storage 33 and/or transmitted to the connection module 4.

In order to avoid errors in the documentation that can arise when entering information manually, automated storage in the system can be advantageous. For this purpose, for example, all information is stored in the correct place in the various documents of the installation specification, such as the circuit diagram or the connection diagram. The person carrying out the respective step must then e.g. B. just acknowledge, e.g. B. via an input device such as a touchscreen and/or an electronic item of clothing.

The relevant information that the installation documentation may include includes, for example:

Which component was used (unique, preferably one-to-one identifier)?

- On which machine and at which location on the machine was the specific component installed?

Who connected it and when?

- To which port or connection point was the cable connected?

How was the cable connected?

Was the component connected correctly?

Were there any deviations from the plan? The installation documentation can, for example, B. at least one of the following information can be documented: work steps of the user with additional information about the work steps such as a processing time, which machine is being worked on, which user, for example which installer or mechanic, carried out the work and when, which component is wired and/or been wired, the assembly step has been completed, which port/connection point was used, are there open cables and what are the properties of the open cable, e.g. length, environmental parameters, e.g. temperature, humidity, current project status, protection class, e.g. IP67, the user can also In the event of deviations from the plan, especially workers, enter the reason for the deviation from the plan. The installation documentation can, for example, be stored in a database. If necessary, a user can trigger the documentation with physical actions (keystroke, screen, double click).

Furthermore, an evaluation unit can be provided which evaluates the documented information, preferably the user's processing times for the respective work steps. An artificial intelligence method can also be used for this, which, for example, optimizes the results of the evaluation unit. The results show the user optimization potential in order to make a machine more efficient in the future, to optimize components or assemblies and to improve assembly and dismantling processes. Furthermore, the comments are taken into account in the event of deviations from the plan.

It is also possible for the documentation to work with a connection module 4 that is not preconfigured or connected to a PLC. This avoids errors that can arise from using connection modules 4 that are externally identical but configured differently. Due to the communication capability of these components and the integration of all relevant information, the system can also be used to guide the user when installing the automation technology. The systematic collection and documentation of all relevant information, such as the components used, the execution of installation and maintenance tasks or problems that have occurred, also lead to secure knowledge about the current system status. By automatically collecting and assigning this information, the process is significantly accelerated and human installers are relieved of the documentation task. Through the automated collection and storage of information to be documented information, the risk of missing and/or incorrect documentation can be significantly reduced.

In Fig. 4, a method 100 according to exemplary embodiments of the invention is visualized with further details. A user can first carry out a user registration 301 via an installation device 31 shown in FIG. 3, i.e. a computer 31, such as a tablet or laptop. For this purpose, the user can use a graphical user interface 32, which is provided by the computer 31. A project selection 302 can also be made via the user interface 32, through which, for example, an installation specification 200 is loaded for a desired project. This makes it possible to initiate a start 303 for instructions for the user to install the machine 1 using at least one installation instruction.

Optionally, after the beginning 303, a representation 304 of the last step carried out can first take place, for example the last installation instructions and/or another instruction for the installation. First, an identification 305 of an installation element 10 can be carried out by the user, for which the user uses, for example, a detection device 22 such as a hand scanner for scanning an identification means 12 on the installation element 10. Using the scanned identification means 12, the identifier 11 can then be determined and transmitted to the computer 31 and/or a device 30 for data processing. Based on the received identifier 11 and the installation specification 200, the connection module 4 and the connection point 42 to which the installation element 10 is to be connected can then be identified. For this purpose, the installation specification 200 includes, for example, a matrix in which various installation elements 10 are assigned to the connection modules 4. The installation instructions can then inform the user which of the connection modules 4 was identified. For this purpose, for example, a display element 41 on the connection module 4 lights up. This can be done by a

Signal transmission 306 from the data processing device 30 to the connection module 4 is enabled. The user can then establish a connection 307 between the installation element 10 and the connection module 4. The installation specification 200 can be used to confirm 308 that the installation has been carried out correctly. Then, if necessary, at least partially automated documentation 309 of the correct installation and documentation 310 of the completion of the work step in the installation specification 200 is possible. This can be done, for example, by a representation 311 in a machine overview with a green tick or, for example, by displaying the relevant Connection can be made in an electrical circuit diagram and presented to the user via the user interface 32. An installation element 312 can then be identified again. By instructing the user, in particular the worker, during the installation of the electrical automation technology and by automatically checking whether a suitable component has been connected correctly, error-free production of the system 2 can be ensured.

The user can then establish a connection between the installation element and a device, such as an actuator and/or a hub and/or a sensor (not shown). Correct assembly can be confirmed using installation specification 200. Then, at least partially automated documentation of correct assembly and documentation of completion of the work step in installation specification 200 is possible. This can be done, for example, by displaying it in a machine overview with a green check mark or, for example, by displaying the connection in question in an electrical circuit diagram and presenting it to the user via user interface 32. These work steps correspond in principle to work steps 307 to 311.

Although some aspects have been described in connection with a device, it is clear that these aspects also represent a description of the corresponding method, where an element or device corresponds to a method step or a feature of a method step. Analogously, aspects that are described in connection with a method step also represent a description of a corresponding block or element or feature of a corresponding device.
