Description

[0001] The present invention relates to a user device for at least one vacuum device and to a vacuum arrangement equipped with such a user device.

[0002] Vacuum devices are typically operated via user devices, which can be designed as display and control devices. Such display and control devices are typically designed for the connection of only one specific vacuum device type. For example, such a display and control device can be designed for the connection of a specific vacuum pump or a specific gauge. Furthermore, conventional display and control devices offer only limited and fixed display options. Depending on the specific system configuration, this can result in significant operating effort or even considerable equipment complexity.

[0003] DE 20 2018 102 484 U describes a graphical programming of process sequences in vacuum devices. US 2003 / 014160 A1 is dedicated to networks of pumps that can be controlled via a web interface with various predefined functional views. EP 2 573 403 A1 discloses a pump for a heating system. The pump has a control device with a display that can display user applications available from the internet.

[0004] Against this background, the object of the present invention is to provide a user device for at least one vacuum device that ensures increased flexibility of use and a reduction in the technical complexity of operating vacuum devices. The object is also to provide a vacuum arrangement with such a user device.

[0005] With regard to a user device, this object has been achieved according to the invention with a device having the features of claim 1. A vacuum arrangement according to the invention is the subject of claim 11.

[0006] A user device according to the invention is designed for use with at least one vacuum device. The user device is designed to display vacuum device-specific content and / or is configured for user-side operation of a vacuum device connected to the user device. Such a user device can thus be a display and / or operating device.

[0007] A vacuum device in question here can be, in particular, a vacuum pump, a vacuum measuring device, a vacuum analysis device, a leak detector, and / or a vacuum valve. A vacuum device can also be a vacuum chamber device. A vacuum pump can advantageously be designed as a turbomolecular pump. Likewise, a vacuum pump can be a backing pump, in particular for a vacuum pump arrangement that also includes a turbomolecular pump.

[0008] A user device according to the invention comprises at least one central unit for user interaction with at least one vacuum device and at least one interface for establishing a data connection between the central unit and a vacuum device. The central unit is equipped with a display and / or input device for displaying at least one functional view with at least one functional object. According to the invention, the at least one functional view is configurable without programming.

[0009] The term "programming-free" here means that any configurations can be made without accessing or modifying the source code. Therefore, separate programming through adaptation or reformulation of source code is not required with programming-free configurability.

[0010] According to the invention, the flexibility of use of the user device is improved by the programming-free configurability of at least one functional view. In particular, it is possible to use the user device for different application scenarios without requiring adaptation through programming at the source code level. The operating effort or the technical complexity of the device for different application conditions can be reduced in this way.

[0011] Compared to simply selecting predefined functional views, the programming-free configurability provided by the invention makes it particularly easy to adapt the user device or prepare it for the intended operating conditions. The user device is thus versatile. In particular, this expands the range of applications of the user device and improves user-friendliness, as a restriction to predefined functional views that can only be selected by the respective user is no longer necessary.

[0012] The at least one functional object of the functional view can be a control element for operating a vacuum device that has a data connection with the central unit. The functional object can therefore be designed as an input field or input surface. Such a control element can enable input using various methods, for example, by pressing, releasing, and / or swiping by a user.

[0013] Additionally or alternatively, the functional object can contain device-specific content from vacuum devices that are connected to the central unit via a data link. Thus, the functional object can be used to display data content relating to all possible information or data sources present in a vacuum device, for example, metadata, in particular hardware and / or software versions and / or names, process information, in particular current, voltage, power, temperature, pressure and / or speed, and / or configuration settings, in particular operating modes and / or accessories. The data content can also relate to variable data points and / or commands for initiating specific process steps, in particular data sinks, for example, commands for switching a drive on and / or off, specifications for process parameters, such as power, speed, pressure and / or flow, and / or configuration settings.The data content can also involve combinations of data sources and data sinks. The functional object can be a graphic display for displaying any content, especially context-specific content.

[0014] In a further preferred manner, the data contents can, on the one hand, be known to the user and / or the user device, in particular the central unit, and / or be named using appropriate nomenclature, for example process value #1 of a vacuum pump at serial address #2 via RS485 connection #3 on optional module #4. However, information about the data contents present in a connected vacuum device can also be obtained via a serial interface and displayed for selection, in particular if the connected vacuum device supports this. The data contents can also be described using meta information, for example addressing of the data content (e.g. parameter number), name, physical unit, handling options (reading, writing, access restrictions), data type, minimum / maximum values for input and / or display.

[0015] According to a preferred embodiment, the at least one functional view is configurable by programming-free regeneration. Thus, depending on the operating conditions, a desired or required functional view can be generated, wherein, according to the invention, a functional view to be generated is configurable without programming. The regeneration of the functional view can therefore be performed without accessing or modifying the source code, which can be stored in a memory unit of the central unit. In contrast to simply selecting a view, regeneration thus involves an original generation of the functional view.

[0016] It is also possible for at least one functional view to be configurable by adapting an existing functional view without programming. This means that an already stored or predefined functional view can be configured or reconfigured through adaptation. For example, individual functional elements can be added and / or removed. This can reduce the user effort required to configure the user device for the desired operating conditions.

[0017] According to a further preferred embodiment, the at least one functional view can be fully and / or partially configurable by programming-free new creation and / or by programming-free adaptation of an existing functional view. The configurability accordingly relates to a portion of the functional view or to the entire functional view. The possibility of programming-free configurability of the entire functional view allows for particularly high levels of flexibility in use. The possibility of partial configurability of the functional view can reduce the user effort required to configure the user device for the respective intended use or prevent the removal of security-relevant functional elements.In particular, parts of the functional view can be unchangeable or fixed, which means that, for example, assistance for a user or safety-relevant functional elements can be constantly available.

[0018] According to the invention, the functional view can be configured without programming by creating, selecting, and / or adapting a functional object and / or a plurality of functional objects and / or by assembling a plurality of selectable functional objects. The assembly of functional objects can be carried out from existing functional objects. For example, it is possible to combine individual functional views from different predefined functional views into a newly configured functional view. This can, for example, create an overview of selected functional elements in a single functional view. The need to switch between different functional views during operation can thus be avoided or at least reduced.This applies in particular to cases where users require frequent access to functional elements of different preset functional views.

[0019] According to a particularly preferred embodiment, the type, position, shape, size, and / or display type of the at least one functional object can be selected and / or adapted without programming. The configuration flexibility of the at least one functional view can be further improved in this way.

[0020] The type of the respective functional object can, for example, be a text display, graphic display, indicator, button, controller and / or graph. The position, shape or size of a functional object can, for example, be temporarily changed; in particular, a temporary magnification to a maximum display can occur, which can achieve a special signaling effect or particularly good legibility for a user. The display type of a functional object can relate to a text form, a symbol form or the alignment of text and symbol displays. The display type can also include constant and / or dynamic displays. For example, foreground or background colors or color adjustments can be predefined depending on predefined conditions, such as parameter threshold values.

[0021] It may also be advantageous if the functional objects are linked and / or linkable to data objects in the same way as the functional views, in particular permanently, automatically, and / or manually. Data objects as data sources and / or data sinks can be present both in connected vacuum devices, for example, as the actual pressure value of a measuring tube, and / or in parts of the user device, for example, in or at a digital output in an expansion module. Graphic properties of the functional object, such as size, position, foreground / background color, shape, text, icons, or the like, can be either statically defined or definable, or defined or definable by one or more conditions.For example, a functional element can be linked to the actual pressure of a connected vacuum gauge and the color of the functional element can be colored depending on application-specific threshold values ("process pressure reached": green, "process pressure not reached": yellow, "process pressure critical": red) and provided with corresponding texts.

[0022] According to the invention, the central unit is configured to automatically recognize a device and / or system configuration. In this way, the central unit can automatically recognize the prevailing device and / or system configuration, i.e., without further input from a user, and, if appropriate, also recognize the intended intended use of the device and / or system configuration. Such recognition is used to support the programming-free configuration of at least one functional view.

[0023] According to the invention, the functional view can be configured in a context-specific manner, namely depending on a recognized device and / or system configuration. Accordingly, the central unit can first perform a recognition process for the respective existing device and / or system configuration. Depending on the recognized device and / or system configuration, a programming-free configuration of at least one functional view is then carried out. Since the configuration takes place depending on a device and / or system configuration, it is a context-specific configuration. The central unit is thus set up for the automated configuration of at least one functional view depending on a recognized device and / or system configuration. Accordingly, a respectively recognized device and / or system configuration automatically triggers a configuration of the functional view.Such configuration, based on a recognized device and / or system configuration, occurs without user input, thus further reducing the setup effort for such a user device. In addition, the functional view can be configured by the user according to preset specifications or even independently of preset specifications without programming. Configuration according to preset specifications or independently of preset specifications can be performed independently of the existing device and / or system configuration. This improves the customizability of the user device according to the user's requirements, thus further increasing its flexibility.

[0024] According to a further preferred embodiment, the interface can be provided on the central unit or on an expansion module connected to the central unit. The interface can be configured for the connection of different device types. It is also possible to provide a plurality of interfaces that can be designed for the same device type or for different device types. Two interfaces can be designed identically and / or differently. Differently designed interfaces can be provided in particular for the connection of different device types. Likewise, different device types can be connected to one and the same interface. Finally, a plurality of interfaces can be provided on the central unit, in particular directly on the central unit.Furthermore, at least one interface can be provided on the central unit and at least one further interface on an expansion module.

[0025] At least one interface of the central unit can be designed as a so-called default interface, via which initial programming or configuration of the central unit can be performed, in particular by connecting it to an external computer. Furthermore, the central unit can also have one or more interfaces for establishing a data connection with a vacuum device.

[0026] In a further preferred embodiment, the central unit can be expanded by at least one expansion module, preferably by a plurality of expansion modules. Such an expansion module allows the functionality of the central unit to be designed flexibly and according to user requirements. A respective device configuration can be determined by arranging and / or omitting at least one expansion module. In particular, a device configuration can be determined by the type of expansion module and / or the number of expansion modules. The device configuration thus relates to the combination of the central unit and any expansion modules present.

[0027] Advantageously, the at least one expansion module can be designed as an interface module for establishing a data connection with a vacuum device. The interface of the user device can thus be provided on such an interface module. Likewise, the user device can have a plurality of interfaces. Multiple interfaces can be provided on one or more interface modules. It is also possible to provide a plurality of interface modules, each having one interface or a plurality of interfaces.

[0028] In a further preferred embodiment, at least one expansion module can be a module for inputting, recording, and / or outputting digital and / or analog signals. Such a signal module can be used, for example, to measure environmental parameters and / or technical operating parameters, such as pressure in a medium to be conveyed.

[0029] In a further preferred embodiment, at least one expansion module can be designed as a module for communication with higher-level controllers. Such a module is, for example, a so-called Ethernet module. Instead of an Ethernet module, any other type of suitable interface for process control is also conceivable, for example, DeviceNet, CANopen, Profibus, Ethernet with more extensive protocols and profiles, in particular EtherCAT, Profinet, Ethernet / IP, TCP / IP, UDP, MTTQ, OPC UA, or the like.

[0030] By communicating with higher-level controllers, older vacuum devices or a group of vacuum devices can be controlled with a separate controller. This is advantageous, for example, when the vacuum devices cannot be addressed directly by the higher-level controller, but are connected directly to the user device via interfaces and / or expansion modules, and the higher-level controller then gains access to them via the user device. This allows for a higher degree of compatibility of the user device.

[0031] In a further preferred manner, at least one of the expansion modules can be designed as a module for controlling storage media, in particular fixed storage media and / or removable storage media. It is also possible for at least one of the expansion modules to contain a storage device. Relevant operating data can thus be securely stored or made available for further use, thereby ensuring improved and safe operation of vacuum devices.

[0032] According to a further preferred embodiment, at least one expansion module can be designed as a power supply module, in particular for supplying current and / or voltage to the central unit, a vacuum device connected to the central unit, and / or an additionally provided expansion module. Such a power supply module thus supplies the central unit, a vacuum device, and / or another expansion module with current or voltage.

[0033] It is possible for a total of one power supply module or multiple power supply modules to be provided. If a single power supply module is provided, this can be configured to supply current or voltage to the central unit. Furthermore, the power supply module can indirectly ensure a current or voltage supply to connected vacuum devices or additional expansion modules via the central unit. This applies in particular if the current or voltage requirements of connected vacuum devices or additional expansion modules are low. Likewise, multiple power supply modules can be provided, with each of the power supply modules supplying different units. One of the power supply modules can be configured to supply current and / or voltage to the central unit, and another power supply module can be configured to supply current and / or voltage to a connected vacuum device.Finally, it is also possible for at least one power supply module to be arranged externally, for example, as part of a connected vacuum device. An external power supply module can, in turn, be arranged to supply current or voltage to the central unit and / or an expansion module.

[0034] According to the invention, the system configuration can be determined by establishing a data connection between the central unit and at least one vacuum device, in particular by the type of vacuum device and / or by the number of vacuum devices. Thus, the user device can establish a data connection with one or more vacuum devices via the central unit. As soon as a corresponding data connection is established, a system configuration results from the entire arrangement of the user device and the vacuum devices in data communication with the central unit of the user device. Such a system configuration can be selected and implemented depending on the respective technical requirements. Due to the programming-free configurability of the at least one functional view, the user device can be suitable for a particularly large number of different system configurations.In particular, the programming-free configuration of at least one functional view can be carried out depending on the respective prevailing system configuration consisting of the user device and the respective connected vacuum device.

[0035] It may also be advantageous if the at least one functional object is linked to, or configured to be linked to, a data object of the central unit, an expansion module, and / or a vacuum device having a data connection with the central unit. A functional object provided in the functional view can thus be generated based on data from the central unit, an expansion module, and / or a vacuum device, or can be permanently linked for ongoing updating. This ensures suitable access by a user to data objects of the central unit, any expansion module provided, or a connected vacuum device.

[0036] It may also be advantageous if the display and / or input device of the central unit is configured to display a plurality of functional views and / or different functional views. The different functional views can be configured without programming according to different criteria. It is also possible for at least one functional view and / or at least one functional object of a functional view to be predefined or predetermined.

[0037] The respective functional view or functional object can be designed to be either fixed or reconfigurable. A fixed design, for example, allows safety-relevant displays to remain permanently displayed, thereby reducing the risk of incorrect operation or preventing the occurrence of hazardous situations. Reconfigurability can enable the adaptation of predefined views or functional objects according to user requirements.

[0038] In a further preferred manner, the functional view can be generated context-specifically and without programming, depending on a recognized pumping station configuration. The context-specific functional view can preferably comprise functional objects required or suitable for the recognized pumping station configuration. A recognized pumping station configuration can, in particular, be a pumping station with a turbomolecular pump and / or with a backing pump.

[0039] Context-specific generation of a functional view based on a recognized pumping station configuration can ensure the setup of a user device for a pumping station in a particularly simple manner. By connecting the respective vacuum devices of the pumping station to the central unit of the user device, the pumping station configuration can be recognized, and, based on the recognition, the functional view can be configured without programming. By providing required or suitable functional objects for the respective pumping station configuration, the user effort required to configure the central unit or the respective functional view is reduced.

[0040] In a further advantageous manner, the central unit can be configured to display a configuration view. The operating mode of the central unit itself can be set via such a configuration view. Such a configuration view can therefore be a temporary view used to set or configure the central unit. Furthermore, the configuration view can be used to configure or generate a functional view without programming.

[0041] Such a configuration view can preferably contain a list of functional objects and / or data objects, in particular data objects of the central unit, an expansion module, and / or a vacuum device connected to the central unit. These data objects can also be device- and / or system-independent data objects. Such data objects are therefore independent of the configuration of the central unit, any expansion modules provided, and / or the vacuum device connected to the central unit. Such independent data objects can be, for example, web content or help information.

[0042] A further aspect of the present invention relates to a vacuum arrangement with a user device as described above and at least one vacuum device which is in data communication with the central unit of the user device via the interface of the user device.

[0043] Such a vacuum arrangement can be configured or assembled particularly easily, and the respective user device can be set up or adapted to the respective configuration of the vacuum arrangement with minimal effort. This simplifies operation of the entire application. No intervention in the source code of the user device's central unit is required for setup.

[0044] A user device as described above may be suitable for operation with vacuum devices and / or general equipment or components of the respective application or vacuum arrangement. For example, a display, such as a warning lamp, can be controlled via a relay and / or digital output of an expansion module.

[0045] The invention is described below by way of example with reference to the accompanying drawing. It shows: Fig. 1 is a schematic representation of a vacuum arrangement with a user device according to an embodiment of the present invention.

[0046] The Fig. 1shows a schematic representation of a vacuum arrangement 10. The vacuum arrangement 10 comprises a user device 12 and at least one vacuum device 14. In the present example, a total of five vacuum devices 14 are schematically indicated, although a different number of vacuum devices 14 may also be provided.

[0047] The vacuum devices 14 can be, for example, vacuum pumps, in particular turbomolecular pumps, vacuum measuring devices, vacuum analysis devices, leak detectors, and / or vacuum valves. Likewise, a vacuum device 14 can also be a vacuum chamber device.

[0048] A vacuum arrangement 10 may comprise a plurality of identical vacuum devices 14 or different types of vacuum devices 14. Vacuum arrangements 10 with one or more vacuum devices 14 and one or more user devices 12 are also possible.

[0049] A user device 12 according to the invention for a vacuum device 14 has a central unit 16 for user interaction with at least one vacuum device 14 and at least one interface 18 for establishing a data connection between the central unit 16 and a vacuum device 14. The interface 18 can be provided, for example, on the central unit 16.

[0050] The user device 12 can further be equipped with at least one expansion module 20, in particular with a plurality of expansion modules 20. The expansion modules 20 serve to expand the functionality of the central unit 16 and can be connected to the central unit 16 via a bus connection 22. For this purpose, the central unit 16 can be equipped with an internal interface 24. The bus connection 22 can, in particular, be a CAN bus. Other bus connections can also be provided, for example, I2C, RS485 and / or LVDS. The expansion modules 20 can provide different functionalities. For example, interface modules 26 can be provided, each equipped with an interface 28 for establishing a data connection between the central unit 16 and a vacuum device 14. The interface 28 can be provided in addition to or alternatively to the interface 18.Furthermore, a module 30 can be provided for inputting, capturing, and / or outputting digital and / or analog signals. Finally, a module 32 can be provided for communicating with a higher-level controller 34. A higher-level controller 34 can, in turn, control a vacuum device or a plurality of vacuum devices. Finally, a module 36 can also be provided for controlling storage media. The module 36 can, for example, be a module with a USB interface. Other interfaces to storage media can also be provided, for example, MMC, SD, and / or µSD.

[0051] Finally, the central unit 16 can be equipped with a so-called default interface 38, via which the central unit can be preconfigured at the factory or an initial configuration can be performed by installing software. However, the default interface 38 can also be implemented via interface 18, so that in the minimal configuration, only interface 18 can be used for software updates and other access during production. Interface 18 can therefore be used as the default interface.

[0052] Furthermore, at least one expansion module can be designed as a power supply module 40. The power supply module 40 serves to supply current or voltage to the central unit 16. Vacuum devices 14 can also be supplied with current or voltage via the central unit 16, particularly if they only have a low current or voltage requirement. In contrast, a further power supply module 42 can also be provided for the direct current and / or voltage supply to one or more vacuum devices. However, a single power supply 40 or 42 can also supply the central unit 16, the expansion modules 20, the vacuum devices 14 connected to the central unit 16 and / or to the expansion modules 20, and a vacuum device 14 connected directly to the user device 12.Finally, individual expansion modules 20 can also be supplied with power or voltage via the power supply module 40, indirectly via the central unit 16. For example, the module 36 for controlling storage media can be supplied with power or voltage via the power supply module 40.

[0053] The central unit 16 may further comprise an internal storage device 44 on which operating software or other data may be stored. Such operating software may, in particular, be a computer program product.

[0054] Furthermore, the central unit 16 has a display and / or input device 46 for displaying at least one functional view 48. The functional view 48 in turn has at least one functional object 50 or a plurality of functional objects 50.

[0055] The functional elements 50 can, for example, be graphic displays for displaying any content or vacuum device-specific content. The functional objects 50 can also be input fields that ensure flexible operation of a vacuum device 14. The display and / or input device 46 can, in particular, be designed as a touch panel, so that graphic displays and input fields can be combined together in one display.

[0056] According to the invention, the at least one functional view 48 is configurable without programming. For this purpose, individual functional objects 50 or multiple functional objects 50 can be created, selected, and / or adapted. It is also possible to appropriately combine predefined functional objects 50 in a functional view 48 and thereby perform a configuration. The functional objects 50 can, for example, be selected from a plurality of different predefined views and appropriately combined in a newly configured view, thereby allowing user requirements to be implemented flexibly.

[0057] Programming-free configurability ensures, in particular, adjustments or new creations of a functional view without accessing source code. Adapting the respective functional view 48 thus requires no programming effort at the source code level.

[0058] The central unit 16 is configured to recognize a device configuration consisting of the composition of the central unit 16 and any provided expansion modules 20. Depending on such recognition, the respective functional view 48 is configured or generated. Such generation can occur with or without user input, in particular automatically. The central unit 16 is configured to recognize a system configuration formed by the user device 12 and the vacuum devices 14 that are in data communication with the central unit 16, automatically, i.e. without user input. Again depending on such recognition, a functional view 48 is configured or generated. The recognition of the respective system configuration will lead to the configuration of a functional view 48 that contains the functional objects 50 that are useful for the respective provided system configuration.Additionally, the functional view 48 can also be configured by the user based on specific specifications. The user can also provide functional objects 50 that display or contain content independent of the operating device 12 or connected vacuum devices 14.

[0059] The modular design of the user device 12 and the resulting flexibility for designing various vacuum arrangements 10 create a high degree of flexibility in use. At the same time, the programming-free configurability of at least one functional view 48 ensures good adaptability of the user device 12 to different circumstances. This simplifies the setup and operation of a vacuum device system 10 overall, and reduces the technical complexity of the device.
