Definitions
- the invention relates to an adaptation module for connecting network elements to a data network, for example an Advanced Physical Layer (APL) Ethernet network in process automation, regardless of type, a data transmission system that has such an adaptation module, and the use of such an adaptation module.
- APL Advanced Physical Layer
- Fieldbuses can transmit data digitally according to a protocol or transmit analog signals via special lines.
- An Ethernet connection can be used for digital signals.
- existing analogue sensors cannot be integrated directly into a digital network. The same applies to many of the existing digital sensors.
- the described embodiments similarly relate to the adaptation module for the type-independent connection of network elements with an Advanced Physical Layer (APL) Ethernet network in process automation, the data transmission system, and the use of such an adaptation module. Synergy effects may result from various combinations of embodiments, although they may not be described in detail.
- APL Advanced Physical Layer
- an adaptation module for the type-independent connection of network elements of a data network or for the connection of network elements with a data network, for example an Advanced Physical Layer (APL) Ethernet network in process automation.
- the adaptation module is set up, according to the direction of communication, to convert data, e.g. APL Ethernet data, from the data network into analog signals for an analog network element type or to convert analog signals into data for the data network in order to connect a network element of analog type to the data network .
- APL Advanced Physical Layer
- An analog sensor or other network element that is connected to the adaptation module can thereby communicate with other components in a data transmission system via the data network, in particular a process automation network.
- communication can be unidirectional in one direction or the other, or bidirectional.
- the adaptation module has interfaces, for example, which are compatible with the sensor or device on the one hand and compatible with the protocol used, in particular the physical layer, for example according to the APL standard, on the other hand.
- an analog sensor or an analog device can be linked or integrated into the data transmission system in a simple manner.
- the term "signal” is used in this disclosure in connection with the transmission of analog voltages or analog currents.
- data is used in connection with the transmission of digital voltages or currents.
- a “digital signal”, such as a digital control signal, is therefore also covered by the term “data” in this disclosure.
- the data can be data or signals in the physical layer, so that it is not only user data, but also transport data including packed user data in a specified physical form, for example generated according to the layer model.
- type in “type-independent” refers to whether a network element, in particular a network element, is an analog or a digital device type. This means that in the case of a type-independent connection of network elements, an analog device can be communicatively connected to a digital device, or the devices can be connected to one another with devices of the same type in the sense of analog/digital.
- Process automation or process automation in the industrial environment can be understood as a sub-area of technology that includes all measures for the operation of machines and systems without human intervention.
- One goal of process automation is to automate the interaction of individual components of a plant in the chemical, food, pharmaceutical, petroleum, paper, cement, shipping or mining sectors.
- a large number of sensors can be used for this purpose, which are particularly adapted to the specific requirements of the process industry, such as mechanical stability, insensitivity to contamination, extreme temperatures and extreme pressures.
- Measured values from these sensors are usually transmitted to a control room, in which process parameters such as fill level, limit level, flow rate, pressure or density can be monitored and settings for the entire plant can be changed manually or automatically.
- a sub-area of process automation or process automation in the industrial environment relates to logistics automation.
- processes within a building or within a single logistics facility are automated in the field of logistics automation.
- Typical applications are, for example, systems for logistics automation in the area of baggage and freight handling at airports, in the area of traffic monitoring (toll systems), in retail, in parcel distribution or else in the field of building security (access control).
- traffic monitoring toll systems
- retail in parcel distribution or else in the field of building security (access control).
- Sensors based on optical measuring methods using lasers, LEDs, 2D cameras or 3D cameras, which record distances according to the transit time principle (time of flight, ToF), can be used for this purpose.
- factory/manufacturing automation Another sub-area of process automation in the industrial environment relates to factory/manufacturing automation. Use cases for this can be found in a wide variety of industries such as automobile manufacturing, food production, the pharmaceutical industry or generally in the field of packaging.
- the aim of factory automation is to automate the production of goods using machines, production lines and/or robots, i. H. run without human intervention.
- the sensors used here and the specific requirements with regard to the measurement accuracy when detecting the position and size of an object are comparable to those in the previous example of logistics automation.
- a network element is to be understood in particular as a process automation device.
- a “process automation device” is a process automation device in a process automation network. Such a device may be, for example, a sensor, actuator, controller, display device, or other device, as discussed more fully below.
- the term “device” in this disclosure means in particular such a process automation device.
- a network element can also be a sensor, controller, etc. in a network other than a process automation network.
- the term “device” therefore also generally includes a network device such as a sensor, control unit, etc. in any data network or data transmission system that has a data network.
- the higher layer network protocols used in the data network can be, for example, EtherNet/IP, HART (Highway Addressable Remote Transducer)-IP, OPC-UA (Open Platform Communications Unified Architecture), PROFINET, or any other protocol.
- the physical layer can be, for example, Ethernet, Fast-Ethernet, Gigabit, Wifi, APL (Advanced Physical Layer) or a physical layer of any other protocol.
- the configuration or setup of the adjustment module can be provided at least in part by software, a program or computer program, a program element and/or hard-wired logic.
- the program element can be a part of a computer program, but it can also be an entire program in itself. For example, the program element can be used to update an already existing computer program in order to arrive at the present invention.
- the programmed logic may be stored on a computer-readable medium, which may be considered a storage medium, such as a thumb drive, CD, DVD, data storage device, hard drive, or any other storage medium.
- the customization module may include a processor, a general purpose central processing unit (CPU), a graphics processing unit (GPU), a microcontroller, a microcomputer, a programmable logic controller (PLC), a reduced instruction set processor (RISC processor), an FPGA (Field Programmable Gate Array), a digital signal processing device (DSP), an application specific integrated circuit (ASIC) and/or other programmable circuits or processing devices.
- CPU general purpose central processing unit
- GPU graphics processing unit
- microcontroller a microcomputer
- PLC programmable logic controller
- RISC processor reduced instruction set processor
- FPGA Field Programmable Gate Array
- DSP digital signal processing device
- ASIC application specific integrated circuit
- the adaptation module is further set up to convert data of a network element of digital type into data for the data network according to the communication direction to convert data from the data network into digital data for the network element of digital type.
- a digital network element can also be connected to the adaptation module.
- the digital data are brought into a form that corresponds to the relevant standard or protocol, for example the APL standard. While with an analogue type the data still has to be converted from analogue to digital, this is not necessary with the digital type.
- the data must be packed for transmission in accordance with the Ethernet standard, for example.
- the data must pass through the layers of the protocol used up to the physical level.
- the term "convert" is therefore to be understood as protocol conversion up to the physical layer. This means that even if the data is already available according to the data link layer (OSI Layer 2), the conversion would make the data link layer data available be made according to the APL standard with regard to the physical layer (OSI Layer 1), for example.
- the adaptation module is also set up to pass data through from or to a network element of a data network-compatible type in accordance with the communication direction.
- a protocol-compliant, e.g. APL-compliant, digital device can also be connected to the adaptation module. In this case, no conversion is necessary.
- the data provided by the device is already physically in a form that corresponds to the standard and can therefore be sent directly from the device to the device receiving the data via the Ethernet lines, for example.
- the data generated by the device is then "pushed through" by the adaptation module.
- the passing through does not exclude the processing of the data. For example, a clock or the edges of the digital voltage transitions or voltage levels can be recovered, or filters can be run through, for example.
- the adaptation module is further set up to provide the power supply according to a specification of the network element type to be connected.
- the device is an actuator of a specification type that provides sufficient power supply.
- the customization module is set up to meet the specification of this specification type.
- the adaptation module can also be designed in such a way that it can be programmed by the user according to a device specification and can provide a corresponding voltage and current supply.
- the adaptation module can also contain a parameterizable threshold value in order to generate an analog or digital signal when this value is exceeded.
- the hardware interface i.e. e.g. sockets, plug connections and cables, can be preconfigured here.
- the adaptation module is integrated into a network element or mechanically connected to a network element.
- the adaptation module can thus be both an independent device with a housing and also part of an independent device, or else a module with or without a housing that is integrated into a network element.
- an existing device can accommodate an expansion card that includes the adjustment module.
- the card could also have a hardware interface.
- an existing device For example, receive a modified housing so that the adjustment module can be accommodated in the device and the hardware interface can be retrofitted.
- “Mechanically connected” means that the adjustment module is attached to the device, for example, by a screw connection, a click fastener, a retaining bracket or in some other way. As a result, the adjustment module can be quickly and easily attached and also detached from the device again.
- the adjustment module can be located in a control cabinet and connected to the existing wiring of a device in order to be able to transfer this to the data network, e.g. APL network, without great effort.
- the data network e.g. APL network
- the adaptation module has a wireless communication unit and is set up to communicate wirelessly with a network element of analog or digital type.
- the device transmits user data via the radio interface using a radio protocol to the adaptation module, which converts the user data into an APL Ethernet format, for example, or vice versa.
- a radio protocol can be a protocol known to those skilled in the art, such as NFC, GSM, UMTS, 5G, WIFI, Zigbee, Bluetooth, LoRa, etc., or a proprietary protocol.
- the adaptation module is set up to convert data and/or signals from a number of and/or for a number of network elements of the same or different type.
- the adaptation module can have multiple interfaces. Several identical or different devices can then be connected simultaneously via the interfaces. In particular, mixed analog and digital devices can also be connected to the adaptation module. If the hardware interface for devices with different communication standards is the same, provision can also be made for these devices to be connected to the adaptation module via this interface as required.
- the electrical/electronic connection and the processing of the protocol can then be switched over manually, i.e. with the participation of an operator and/or e.g. using a predefined configuration, or the adaptation module automatically recognizes the protocol used or the standard of the device.
- the adjustment module has a display for displaying status information.
- Status information is, for example, information about the connection status or about the successful connection of the device, measurement data of the device or an operating state of the adjustment module.
- the adjustment module has a user interface.
- the user interface could be used to disconnect, remotely control the fitting module, select or change a configuration, and even send commands to the device, for example, to request specific information from the device, such as battery level, configuration parameters, etc. if the device is set up for it.
- a user interface can be, for example, an interface to a smartphone or an app on a smartphone, manual on-site operation or it could be an interface to a server for operation and status information to be displayed. This would make it possible, for example, to collect and display information about the current network structure, to operate remote maintenance and update the software of the adjustment module, etc.
- the network elements are process automation devices and the data network is an Advanced Physical Layer (APL) Ethernet network in process automation.
- the adaptation module is set up for the type-independent connection of process automation devices. It is further set up to convert APL Ethernet data from the APL Ethernet network into analog or digital signals for an analog or digital type of process automation device or to convert analog or digital signals into APL data for the APL Ethernet network, to connect a process automation device of analogue or digital type to the data network.
