Description

The invention relates to an electronic slave device of a single-master-slave system of automation technology and / or industrial technology for the processing, conversion and output of the measured values of a sensor integrated in the slave device or an analogue, binary or digital sensor device connectable to the slave device by means of a connection cable and a single-master-slave system with at least one slave device.

This slave device is connected in the operating state via a connecting line to the master of the system. The slave device has a slave ASIC with a sequence control, possibly with an analog / digital conversion part and with a digital part, wherein the analog part is connected to the connection line or can be connected and receives the signals transmitted by the Verbindungsseitung, address bits and information bits or emits the information bits contained in the connection line to be transmitted, wherein the analog / digital conversion part converts analog signals received via the connection line into digital signals or converts digital signals into analog signals to be transmitted from the connection line. On the one hand, the digital part evaluates the signals coming from the analog part via the analog / digital conversion part and processes these if the address bits contained in the signals coincide with an address assigned to the slave. On the other hand, the analog-to-digital conversion part processes signals going to the analog part.

For cost and space reasons, it was not possible until a few years ago to make binary sensors or actuators directly bus compatible with fieldbus systems. Thanks to highly integrated technologies, today's sensors can provide additional functions in addition to the actual switching state, which offer setting and diagnostic options for the sensors or actuators. Up to now, these functions had to be realized by additional cables and thus additional wiring. To overcome these drawbacks, the actuator-sensor interface standard, called the ASi standard, has been created, which is a fieldbus concept that links binary actuators and sensors to the lowest and first control levels, respectively, to make them communicative. The ASi system is used as a relatively new interface for industrial communication and occupies the area below the previous fieldbus systems. In particular, it connects binary sensors and actuators via a bus to the first control level, eg a PLC or a PC. The ASi system consists of several ASi slaves, one ASi master and one or more ASi cables. The heart of the ASi system is the ASi slave of the slave device, which is usually implemented as an ASi chip (ASIC) and with which the actuators or sensors are digitally coupled to the ASi line. The ASi chip is either built into a module, to which conventional actuators and sensors are connected, or it is installed directly in the actuator or sensor. The ASi master forms the interface between the actuators or sensors and the core of the controller, for example a PLC or a PC. The ASi cable is generally an unshielded two-conductor ribbon cable or a standard round cable, which simultaneously transmits signals and power. The ASi (Actuator Sensor Interface) replaces the wiring harness, distribution cabinets, terminal strips, etc. with a simple two-conductor ribbon cable, which exchanges ASi data with the peripheral elements and simultaneously supplies them with energy. With a so-called separate ASi connection in the form of a standardized module, which is part of the bus structure, ASi makes first of all the most conventional peripheral elements bus-connectable. In the case of the integrated ASi connection, however, a so-called slave module is located in a sensor or actuator device and is therefore capable of being bus-enabled. The ASi master takes over all tasks that are necessary for the execution of the bus operation of the slaves, including tasks of initialization and diagnostics. Via the ASi master, a superordinate host computer, such as a programmable logic controller or bus computer or PC or VME bus computer, is connected to the field bus, to which all signals of all ASi slaves are fed, whereby the ASi master ensures that the signals are sent to the Host computers are provided in a fixed time frame and vice versa, the control commands of the host computer are given to the ASi slaves. The ASi master also ensures that additional slaves are detected and failed slaves are reported to the host computer. The ASi master thus adapts the ASi functions of the slaves to the external processing system of the host computer. The ASi system does not transmit the information between a master and the different slaves in parallel, but serially. In each polling cycle, information is transmitted serially from master to each slave and back. They can be used as input or as output data. In order not to have too long waiting times for the serial transmission of the information from the master to the individual slaves or vice versa, a certain structure of the signals transmitted via the ASi line is specified for the ASi system. The dialog of the ASi master with an ASi slave always consists of the combination of telegram of the ASi master and response telegram of the ASi slave. The telegram of the ASi master is also called Master call, the response telegram of the ASi slave referred to as slave response. Via the address bits at the beginning of the master call, each ASi slave is informed whether the following information is intended for it or for another ASi slave. Each ASi slave is thus assigned a five-bit long address, the address 0 has a special function. It is usually used as the default value during manufacture, ie the ASi slaves are assigned the address 0 as per production. If, for example, a defective ASi slave is replaced, the new ASi slave replaces the address 0 with the address of the failed ASi slave, which can be executed by a corresponding ASi master command to the new ASi slave.

In the field of automation technology, single-master systems are also known as point-to-point connection systems such as IO-Link. IO-Link is based on the familiar 3-wire connection of a digital switching signal in which the switching signal is executed as a serial telegram. This allows additional information to be exchanged as a serial protocol between I / O level and field device. IO-Link describes a point-to-point connection between a peripheral interface and a field device. IO-Link is the original and effective concept for uniform connection of sensors and switching devices to the control level by means of a cost-effective point-to-point connection. The new communication standard below the fieldbus level enables central fault diagnostics and location up to the sensor / actuator level and facilitates commissioning and maintenance by allowing parameter data to be changed dynamically directly from within the application. The result: higher system availability and reduced development costs. As an open interface, IO-Link can be integrated into all common fieldbus and automation systems. This type of serial point-to-point connection for the machine level for signal transmission and power supply is

• a) Backward compatible with switching standard PNP sensors
• b) has two operating modes: standard I / O mode (SIO), IO-Link mode
• c) allows bidirectional signal transmission in half-duplex mode
• d) has three parameterization options: automatically via the controller, manually via the device to a PLC, or via external device / tool, for example. Eg PC with a USB-IO-Link master
• e) uses 24V pulse modulation for serial communication over an unshielded one

Three-wire cable with backward compatibility for binary and analog standard sensors.

• b) dem Medium, also der Verbindungsleitung zwischen dem IO-Link-Master-Port und dem Sensor/Aktor. Das Medium stellt die gleichen Anforderungen an die Leitungsparameter oder die Pinbelegung des Steckverbinders wie eine Standard-Sensor/Aktor-Leitung, die heute für binäre Signale eingesetzt wird. Die Leitung darf bis zu 20 m lang sein,
• c) dem IO-Link-Device, das eine beliebige Abbildung von Eingangs- und Ausgangsbits sein kann.

The IO-Link connection system consists of the following components:

• a) the I / O module (IO-Link master, IO-Link controller) in any degree of protection (eg IP20 or IP65 / 67) and a theoretically unlimited number of ports that offer IO-Link master functionality .
• b) the medium, ie the connection cable between the IO-Link master port and the sensor / actuator. The medium places the same requirements on the line parameters or the pin assignment of the connector as a standard sensor / actuator line, which is used today for binary signals. The pipe may be up to 20 m long,
• c) the IO-Link device, which can be any mapping of input and output bits.

In the simplest case, it is a device with one bit of process data, in the more complex case a component with analog process data and binary switching signals. The standard IO-Link describes a serial point-to-point connection for the signal transmission from sensors and actuators to the terminal box on the machine. IO-Link is backwards compatible with standard binary sensors by using the unshielded 3-wire cables from standard sensors as well as different operating modes of the communication software. In contrast to the field level, which connects the individual machines and the control of a plant, IO-Link is thus assigned to the machine level, which is also referred to as sensor-actuator level. The field level can be assigned to the vast majority of standardized fieldbuses used in mechanical and plant engineering. Examples of common fieldbuses are Profibus-DP, Interbus, DeviceNet and CANopen. Highly increasing are Ethernet-based fieldbus standards such as Profinet, EtherNet / IP, EtherCAT and Ethernet Powerlink. Fieldbuses are suitable for long distances and 3 often span several 100 m between the participants and total distances of sometimes more than 10 km. Except for exceptions, these powerful bus systems can not be used economically at the machine level. On the machine level, IO-Link is to be defined as a point-to-point connection of sensor-actuator bus systems such as the AS-Interface, in which the addressing and data transmission between the subscribers takes place via a common line. IO-Link is a serial interface for the simultaneous transmission of power supply and signals via a conventional three-wire cable. Unlike other serial interfaces such as RS-232 or USB, IO-Link requires no shielded cables and is backwards compatible for non-IO-link-capable binary sensors and actuators with three-wire connection. With favorable costs as well as equally economical employability both with simple binary and Even with complex intelligent devices, IO-Link fulfills all requirements to become the standard interface for the connection of sensors and actuators at the machine level - comparable in meaning to the USB interface as the standard for connecting computer peripherals. On the one hand, the core ideas of IO-Link are the use of the unshielded three-wire cable for signal transmission and power supply, which is widespread in binary sensors and actuators, as well as the downward compatibility with non-IO-Link-capable devices. The data transfer via IO-Link always takes place between an IO-Link master and a connected IO-Link device (device) as slave or slave device. Both fieldbus interface modules and PLC interface modules are available as IO-Link masters. IO-Link-capable standard devices can either be connected via special standard IO ports or via the compatible IO-Link ports of the master. (based on "IO-Link - the USB interface for the sensor-actuator level", www.balluff.com ). An IO-Link master can have one or more ports. Only one IO-Link device can be connected to each port. Thus, IO-Link is a point-to-point communication and a single-master-slave system, but not a fieldbus or sensor-actuator network such as ASi.

A fieldbus such. As Profibus, Bitbus and ASi, ASi as sensor-actuator network embodies a Felbbussystem the lowest level, connects in a system field devices such as sensors (sensors) and actuators (actuators) for the purpose of communication with a control device. If several communication participants send their messages over the same line, then it must be determined who (identifier) what (measurement, command) when (initiative) says. There are standardized protocols for this. A fieldbus is generally understood to be a serial bus that connects simple nodes (intelligent sensors and intelligent actuators), but also more complex control units. In the automation pyramid he counts to the lowest level. For some years it has been better to decentralize the intelligence and to connect the individual system units via serial bus systems. Two things were crucial for this. First, it has learned to transfer data increasingly immune to interference and cheaper, z. For example, the RS485 interface, and secondly, the integration of ASICs not only allows low-cost intelligence in the foremost node to lay, but the high packing density of modern electronic units also guarantees low interference and reflections on the lines. The advantages of the serial bus lines and the relatively inexpensive and powerful industrial single-master-slave systems are obvious. It saves installation costs, and in several ways. On the one hand, the number of lines can be drastically reduced and thus also the installation costs. On the other hand, the laying of the remaining lines is much easier: the connection of each unit is the same, the addressing takes place on a higher level of abstraction, and an automation of many system functions is much easier than the conventional central control technology.

A disadvantage of such single-master-slave systems is that the transmission of non-process data, such as configuration data or operating software or their updates from the master via the cable to the slave device due to the low data transfer rates, especially in ASi and IO-Link take quite a long time can. Moreover, this type requires a wired and operational system. There are different methods and devices for the non-master addressing of slave devices and / or the system or communication diagnosis. are quite expensive. A unified concept for the identification and / or transmission of such communication and non-process data does not exist.

The object of the invention is to remedy at least some of these disadvantages, in particular for fairly simple or inexpensive industrial single-master-slave systems such as ASi and IO-Link.

This object is solved by the independent claims. The slave device according to the invention is part of a single-master-slave system according to the invention of automation technology and / or industrial measuring and control technology, the at least process data (measurement and / or control data, possibly processed / processed) of the measured (sensor) or to be controlled (actuator) industrial or automation process via a wired communication line data serially received by the master or can send to this. The slave device includes, among other things, an electronic memory device having a nonvolatile memory. The memory component is connected via a wired memory access interface (wire interface) directly or indirectly datenübertragungsseriell with the slave ASIC and / or an electronic flow control of the slave device. It has, in addition to the wired interface to the slave ASIC or a possibly existing microprocessor or microcontroller component, a second, radio- and antenna-based memory access interface (radio interface) for a transmission frequency range of a radio master from 0.5 to 2000 GHz as the input for the in the memory device integrated transponder. The slave device and the memory component are designed so that non-process data, preferably production and / or identification data of the slave and / or its constituent parts, electronic nameplate data, slave address data, configuration and / or parameterization software and / or data, are written by the write and / or read-only radio mast via an air gap and this radio interface to its nonvolatile memory or one of its memory areas can or are written. The memory component has an integrated auxiliary power supply in addition to an arbiter. This allows the memory component in conjunction with the antenna of the slave device, regardless of the state "lack of operating voltage" with respect to the main power supply of the memory device and / or the slave device over the air gap of the radio interface, the memory device with so much electrical antenna energy from the transmission energy of in the Near the slave device located Funkmasters can be supplied or is supplied that write this non-process data in the non-volatile memory and / or can be read. This presupposes that the radio master has received from the slave device via this radio link the authorization to write and / or read out. Non-process data obtained and read in by the radio master can be read out from the slave ASIC via this wire interface of the memory component, preferably also via the communication line, in the operable state of the slave ASIC and / or the slave device. For this purpose, the slave ASIC or microprocessor or microcontroller is designed as a master and the memory component as a slave of a master-slave data bus. Standardized and established low cost systems are preferably: RS232, SPI, SCI or IIC / I2C. Since a microprocessor or a microcontroller can advantageously be used to fulfill tasks of the slave device because of its very good price-performance ratio, it can simultaneously also be used as the master of this master-slave bus system. It is advantageous, of course, if the master of the single-master-slave system can receive this non-process data or receives on request or can send non-process data to the slave device, then the order by means of this master-slave bus system in the non-volatile memory or a specific memory area of the two-channel radio-memory component are written.

In the following some applications and advantages of the invention are enumerated:
More and more fieldbus and ASi slave devices contain programmable microcomputers (microcontrollers or microprocessors). The functionality is thus increasingly determined by the firmware in these devices. In production, often only basic devices are manufactured, which only in the last production step get the actual functionality by downloading the correct firmware and subsequent calibration. The current ASi does not allow firmware download via the communication interface, therefore a separate programming interface should be provided. Traceability of batch or part defects requires serial or batch numbers and their assignment to production data. In the case of the usual decoupled production steps, this tracing requires a high, but nevertheless error-prone, administrative effort. In order to avoid this expense, devices often receive several printed on the respective components or glued serial numbers that are difficult or impossible to evaluate. In order to be able to carry out a secure check of the firmware version of an embedded slave device, the device must be electrically connected to a diagnostic tool. The version numbers printed on the device or packaging may be incorrect. Parameterizable functionalities should offer the user of the devices a greater benefit. In order to be able to use the new adjustable functionalities on the user side, the devices receive communication interfaces, which are also always cheaper to implement. ASi is a very reasonably priced communication interface. As a result, the number of parameterizable and diagnostics-capable devices in systems increases abruptly. For the identification of the slave devices during commissioning and operation of a system, therefore, unique identifiers such as ASi addresses and equipment designations (BMKZ) are becoming increasingly important. The mechanical installation of systems is usually not done by the programmer responsible for commissioning and often without connection to the central control cabinet. Therefore, the addressing of the devices is carried out only in the assembled state via the ASi-master or by connecting the slave device and addressing device with a special programming cable. The equipment labels are printed out and mechanically attached to the device. These DTM can be damaged or even lost. Addressing via the ASi master can only be carried out with one new device (slave address). The increased quality and warranty demands on equipment manufacturers and equipment manufacturers require monitoring of the equipment used to rule out the use of inferior equipment in the form of counterfeiting. For this purpose, RFID tags could be installed in devices which can be read out and verified during checks in the system or in returns. Reading out is only possible with an RFID reader, the central system diagnostics does not have access to this data. For the end user, however, there is no direct benefit from this RFID solution, so the acceptance is low. For this reason, this functionality is not yet used in ASi. In the case of a mechanical or electrical failure of a device, the set there Parameter as well as the logged operating data are usually no longer read. The diagnosis of the logged operating data is then no longer possible. The parameterization of replacement devices is therefore only possible if these settings have been saved in the higher-level system (eg fieldbus). This is possible with ASi but only with the use of very special slave profiles. A central diagnosis facilitates troubleshooting in the system, but is very limited in ASi available. However, the diagnosis on site still requires a user interface on the terminal. Expert systems as diagnostic aid in the terminal require a lot of effort in the device and also require a user interface. Currently it is possible to connect an addressing device with a jack plug. For addressing, the slave device is supplied with energy from the addressing device. An alternative exists for current ASi systems in the form of an infrared interface, which can optionally be incorporated into devices. The slave device must be supplied via the ASi interface, but the addressing device communicates via infrared LEDs with the ASi-ASIC. The ASi master can not communicate with the slave device at the same time. The diagnostic functionality enables comprehensive central system and device diagnostics. Since the jack plug disconnects the device from the bus, no decentralized diagnosis is possible on the device during bus operation. The capacity of the accumulators of the addressing device must be increased because many more devices per master can be connected and the larger number of setting data considerably lengthens the time of the configuration process. The invention makes it possible, without the Dichtigkeits- or comfort problems of the known solutions wirelessly by means of a low-cost technology such as RFID or NFC non-process data, eg device-specific data via both the radio interface and the non-radio interface on and read. A particular advantage is that the data traffic between the master and the slave device of the single-master system does not have to be interrupted for reading out or reading out such data into or out of the memory component by means of the wireless master.

The invention will be explained in more detail by means of exemplary embodiments. Show it:

• e) This memory device 20 according to the invention has a second, radio- and antenna-based memory access interface (radio interface) for a transmission frequency range of a radio master from 0.5 to 2000 GHz as the input for the memory device in the memory 20 integrated transponder.
• f) The slave device 10v and the memory device 20 are designed so that non-process data, preferably production and / or identification data of the slave and / or its components, electronic nameplate data, slave address data, configuration and / or parameterization software and / or data, from write and / or or readable radio master 40 can be written in the non-volatile memory or one of its memory areas via an air gap and this radio interface data serial.
• g) The memory device 20 has an integrated auxiliary power supply in addition to an arbiter. This allows the memory device 20 in interaction with the antenna of the slave device 10v in that regardless of the state "missing operating voltage" in terms of Main power supply of the memory device 20 and / or the slave device 10 over the air gap of the radio interface, the memory device 20 with so much electrical antenna energy from the transmission energy of the near the slave device 10v located Funkmasters 40 can be supplied or is supplied that this non-process data write to the non-volatile memory and / or can be read. This assumes that the radio master 40 from the slave device 10v has received the authorization to write and / or read out via this radio link.
• h) Non-process data collected by the radio master 40 received and read in, at least from the slave ASIC 10VA over this wire interface of the memory device 20 , preferably also via the communication line, in the operable state of the slave ASICs 10VA and / or the slave device 10v be read out data-serial. This is the slave ASIC 10VA as the master and the memory device 20 designed as a slave of a master-slave data bus. Standardized and established low cost systems are preferably: RS232, SPI, SCI or IIC / I2C. Because to accomplish tasks of the slave device 10v a microprocessor or a microcontroller due to its very good price-performance ratio can be advantageously used, this can also be used as the master of this master-slave bus system. It is advantageous, of course, although the master 30m of the single-master-slave system 50 This non-process data can be obtained or received on request. Since in relatively simple single-master systems or those of the lower levels of the price pressure is great, it makes sense that the radio transmission, the radio master 40 and the radio interface and the transponder underlying protocol or system is not identical to that of the single-master system or the master-slave data bus, ie the system-different protocols or standards are used or implemented. This makes it possible to use established, very inexpensive communication systems (or their components and ICs) such as RFID or NFC. Very advantageous is a enstprechendes phone with such a radio mast 40 ,

Particularly worthwhile is the use of the invention in single-master-slave systems and / or sensor-actuator systems with point-to-point connections, in particular IO-Link, and sensor-actuator networks, especially ASi, since the data transmission rate from master to slave is relatively low at least for non-process data. Among other things, a high non-process data transfer rate can be achieved by the invention, especially if established systems such as RFID or NFC are used. Here it is favorable, if several on the printed circuit board 1 or in the slave device 10v existing computer and / or ICs / ASICS are integrated. The integration of the sensor or actuator can be beneficial due to the higher integration possibility.

To monitor the system or ASi signals on the ASi line, expensive safety monitors are known. By the invention it is possible safety monitor data, state, monitoring and / or diagnostic data by the slave device 10v at this point the ASi line to create and store as non-process data in this non-volatile memory and output via display or non-ASi output means, preferably to the Funkmaster 40 and / or the ASi master 30m , These data are a measure of the communication security or communication uncertainty of the ASi line or the ASi network.

• a) Senden von trägerwellebasierten, modulierten Signalen des maximal 30–50 cm, vorzugsweise nur 10–20 cm, von der Antenne des Funkslaves bzw. Transponders des Slavegerätes 10v entfernten Schreib-Lese-Gerätes (Funkmaster 40) an den Funkslave mit einer Trägerfrequenz im Bereich von 0,5 bis 2000 GHz. Um nicht in der Nähe angeordnete Slavegeräte 10 anzusprechen, weist der Funkmaster 40 als auch das Slavegerät 10 entsprechende Kommunikations-Frequenzen, Verfahren- und -Sendeleistungen nd Gerätgestaltungen auf, so dass der Funkmaster 40 nur bis zu einer maximalen Funkslave-Entfernung von 30–50 cm, vorzugsweise von nur 10–20 cm, Nichtprozeßdaten in den nichtflüchtigen Speicher des Speicherbauelementes schreiben und/oder lesen kann,
• b) Umwandlung der Sendeenergie der Trägerwelle in elektrische Energie durch das Speicherbauelement 20 für den Betrieb des Speicherbauelementes 20 einschließlich des Empfangens und Modulierens von Nichtprozeßdaten vom bzw. zum Funkmaster 40, ggf. auch zum Senden dieser Nichtprozeßdaten;
• c) Dekodieren der Sendesignale des Funkmasters 40 durch den Transponder des Speicherbauelementes 20,

• f) Auslesen aller oder eines Teils dieser Nichtprozeßdaten durch den Slave-ASIC bzw. durch den IC 1m bzw. den Mikrocontroller 1m bzw. den Mikroprozessor 1m im betriebsbereiten Zustand (Betriebsspannung bzw. Hauptversorgungsspannung vorhanden) mittels seines Busmasters über dessen Busleitungen. Sehr günstig ist es, wenn das System und seine Komponenten so gestaltet bzw. eingestellt sind, dass auch drahtserielles Auslesen aller oder eines Teils dieser Nichtprozeßdaten durch den Master 30m möglich ist. Besonders geeignet sind etablierte, relativ preiswerte Kommunikationscerfahren wie RFID- und NFC-Verfahren.

A particular advantage of the invention is that when the memory device 20 Part of the populated and soldered motherboard of the slave device 10v is, non-process data, in particular electronic nameplate data of the slave device and / or its motherboard and / or manufacturing data of the motherboard and / or information about the components used on the motherboard, even before the completion of the slave device 10v to an operational device, via the radio interface of the slave device 10v by means of a radio mast 40 can be written in the non-volatile memory of this memory device. It is of course also beneficial to bring as many components and components to this motherboard, on the one hand, because information about these components, preferably also on the implemented software in the non-volatile memory by means of the radio mast 40 immediately after soldering and / or completing the motherboard 1h can be written and on the other hand, the higher integration density reduces manufacturing costs, possibly also the error rate. Non-process data may be independent of the "missing operating voltage" state of the memory device 20 and / or the slave device 10v from this or another radio master 40 can be read, and preferably this industrial system is designed so that the master 50 Can write non-process data into this non-volatile memory. The method according to the invention for transmitting non-process data from a radio master 40 via a radio slave or transponder into the nonvolatile memory of the memory component 20 the circuit board 1 or main circuit board 1h has the following process steps:

• a) transmission of carrier wave-based, modulated signals of maximum 30-50 cm, preferably only 10-20 cm, from the antenna of the radio slaves or transponder of the slave device 10v remote read-write device (Funkmaster 40 ) at the radio slave with a carrier frequency in the range of 0.5 to 2000 GHz. Not around nearby slave devices 10 to address, the Funkmaster points 40 as well as the slave device 10 corresponding communication frequencies, process and -Sendeleistungen nd device designs on, so that the radio master 40 write and / or read non-process data into the non-volatile memory of the memory device only up to a maximum wireless distance of 30-50 cm, preferably only 10-20 cm,
• b) conversion of the transmission energy of the carrier wave into electrical energy by the memory device 20 for the operation of the memory device 20 including receiving and modulating non-process data to and from the radio master 40 , possibly also for sending this non-process data;
• c) decoding the transmission signals of the radio master 40 through the transponder of the memory component 20 .
• d) Returning signals from the radio slaves or transponder to the radio master 40 solely by using the memory device 20 received transformed transmission energy of the radio master 40 ;
• e) writing non-process data by the radio master 40 in the nonvolatile memory of the memory device 20 , provided the Funkmaster its write permission for this memory device 20 has detected or this has been transmitted to him from the memory device by means of these return signals;
• f) read all or part of this non-process data by the slave ASIC or by the IC 1m or the microcontroller 1m or the microprocessor 1m in the ready state (operating voltage or main supply voltage available) via its bus master via its bus lines. It is very advantageous if the system and its components are designed or set such that even wire-serial read-out of all or part of this non-process data by the master 30m is possible. Particularly suitable are established, relatively inexpensive communication methods such as RFID and NFC methods.

Here is the application of the antenna control switch-based short-circuit modulation of the radio master 40 generated electromagnetic field as transponder-transmitting energy-free form of non-process data transmission. by the transponder or radio slave very advantageous because the transponder does not have to generate its own energy-intensive carrier wave, but short-modulated only the field of the transmitting radio character and the Funkmaster has the ability or must have to recognize this type of modulation. Since there are already mobile phones with Funkmaster functions, it is convenient to perform such a phone so that it functions as a radio mast 40 for a slave device according to the invention 10 or adopt and execute a single-master-slave system according to the invention, ie in particular RFID or NFC-capable. NFC is a bidirectional radio communication designed for very short distances that allows a reader to read small amounts of data from other active devices or passive media (tags, RFID tags) when brought close enough together. With NFC, the reading distance is only a few centimeters.

• a) Produktionsdaten zuordnen: Die Seriennummern können sofort nach PCB-Bestückung vergeben und in das Vor-Gerät (Leiterplatte, Platine) mittels des Funkmasters 40 geschrieben werden. Die Chargeninformationen und Firmware-Stände können bei den weiteren Produktionsschritten ebenso dort abgelegt bzw. aktualisiert werden.
• b) Produktions- bzw. Herstellungsdaten-Verfolgung: Seriennummern und andere Produktdaten sind während des gesamten Produktlebenslaufes einfach auslesbar. Im Lager des Herstellers oder auch bei dessen Kunden sind die Daten auch durch die Verpackung hindurch erfassbar. Vor dem Versand kann bei Bedarf die Seriennummer durch die Verpackung hindurch gelesen und im Lieferschein festgehalten werden. Nach dem Einbau der Slavegeräte in eine Anlage können die Nichtprozeßdaten vom Master 30m, vorzugsweise ASi- oder IO-Link-Master 30m, über die Verbindungsleitung gescannt und die verbauten Slavegeräte 10 und auch deren Komponenten einschließlich der Soft- und Hardwareversionen dokumentiert werden. Bei der Untersuchung von Rückläufern können die Produktionsdaten ausgewertet werden, selbst wenn die (ASi-)Slavegerät-Anschaltung bzw. das (ASi-)Slavegerät 10v nicht mehr funktionstüchtig sein sollte. In diesem Zusammenhang können auch Fälschungen identifiziert werden. Bei Rückruf-Aktionen können Kunden gezielt angesprochen werden, eventuell kann der Kunde aus seiner Anlagendokumentation genau den Einbauort des auszutauschenden Gerätes ermitteln. Die bisherigen Adressierung des ASi-Slaves und Inbetriebnahme sowie Konfiguration ist recht aufwändig bzw. umständlich. Insbesondere weitere ASi-Entwicklungen könnten bzw. werden ggf. in jedem Slavegerät 10 eine eindeutige Seriennummer, Herstellerkennung, Gerätebauart und andere Informationen zur Verfügung stellen. Hier ist die frühe Hinterlegung der Seriennummer und/oder der Typschilddaten sehr vorteilhaft.
• c) Gerätsoftware-/Firmware-aktualisierung: Bei geringem Firmwareumfang kann die Firmware über diese Schnittstelle in das Gerät übertragen werden, ohne das ein Minimalbetriebssystem oder ein Programmieradapter entwickelt werden muss. Solche Geräte könnten auch in der Verpackung auf einen neuen Firmwarestand gebracht werden. Alternativ bietet diese Schnittstelle auch die Möglichkeit, Geräte durch Download von Parametersätzen kurz vor der Auslieferung in eine kundenspezifische Gerätevariante zu verwandeln.
• d) Fälschungsschutz und Manipulationsschutz: Durch verschlüsselte Seriennummern und Prüfsummen lassen sich Fälschungen erkennen. Diese Prüfung kann mit dieser Schnittstelle im Lager als auch über die SPS des Anlagenbauers in der Maschine erfolgen. Dadurch kann sichergestellt werden, dass immer qualitativ und funktional passende Slavegeräte 10v im Austauschfall verwendet werden. Bei Rückläufern können ebenso Fälschungen erkannt werden, oft sogar wenn Teile des Gerätes nicht mehr funktionstüchtig sind. Zusätzlich lassen sich durch einen ähnlichen Mechanismus Passworte vorgeben, die eine Modifikation des Slavegerätes 10v über den Master 30m bzw. ASi oder IO-Link (z.B. bei Fernwartung) nur dann erlauben, wenn dies vorher lokal am Slavegerät 10v über die neue Funk-Schnittstelle freigegeben wurde.
• e) Diagnose: Die zweikanalige Schnittstelle erlaubt es, jederzeit die Version der programmierten Firmware und andere Produktionsdaten drahtgebunden datenseriell über das IC (Microcontroller oder Mikroprozessor) oder das Slave-ASIC sowie drahtlos über Funk mittels des RFID- oder NFC-Schreib-Lese-Gerätes 40 auszulesen. Dies gilt auch für Slavegeräte mit hoher Schutzart, ohne dass diese geöffnet werden müssen. Meldungen und Zustände, die beim Betrieb des Slavegerätes 10v anfallen, können remanent gespeichert und später ausgelesen werden, auch nach einem Slavegerät-10v-Defekt, falls das Speicherbauelement 20 unbeschädigt ist.
• f) Kommunikationsparameter: Die ASi-Adresse des Gerätes 10v kann auch ohne ASi-Spannungsversorgung über die ASi-Leitung (Verbindungskabel) Versorgung ausgelesen und verändert werden. Bei Slavegeräten 10v mit mehreren ASi-Adressen (Multi-Slave-Geräten) können die Adressen aufgrund der Unabhängigkeit vom ASi Protokoll ohne Verfahrenstricks eingestellt oder verändert werden. Zusätzlich können Typschilddaten bzw. Betriebsmittelkennzeichen (BMKZ) und andere Parameter eingestellt werden. Gleiches gilt auch für ähnliche Single-Master-Slave-Systeme 50
• g) Slavegerät-10v-Parameter: Kundenspezifische Slavegeräte 10v können über die zusätzliche Daten-Schnittstelle in Form der (RFID-/NFC-)Luftschnittstelle 21 in der Produktion, oder auch kurz vor Auslieferung, durch Laden von speziellen Parametern, erzeugt werden. Die Einstellung neuer Parameter vor Ort kann ohne Trennung vom Master 30m bzw. Feldbus bzw. Sensor-Aktor-Netzwerk lokal erfolgen, sodass eine manuelle Bedienschnittstelle, z.B. Drucktasten-12e- oder Potentiometer-12e-Bedienung im/am Gerät, oft nicht mehr benötigt wird. Diese drahtlose Einstellung und Prüfung der Parameter ist auch bei Slavegeräten 10v mit hoher Schutzart und Verguss möglich. Durch ein Betriebsmittelkennzeichen (BMKZ) kann der Anwender den Einbauort im Gerät dokumentieren. Speziell bei zukünftigen ASi-Entwicklungen kann dieses Merkmal sehr sinnvoll sein, da dieses System die BMKZ beim ASi-Feldbus-Abtastung für alle Slaves bzw. Slavegeräte 10v auslesen und dokumentieren kann.
• h) Varianten erzeugen: Bei Slavegeräten 10v mit textueller Benutzerschnittstelle kann eine selten verwendete darzustellende Landessprache über diese Schnittstelle hineingeladen werden. Kunden können Parametersets über diese Schnittstelle auslesen und immer wieder Kopien dieser Datensätze in ihre Geräte einspielen (z.B. in Serienmaschinen).

The new, with respect to the transponder memory device 20 two-channel interface thus allows in Slavegeräten invention 20 and systems with one or more such devices 20 following functions:

• a) Assign production data: The serial numbers can be assigned immediately after PCB assembly and into the pre-device (circuit board, circuit board) by means of the radio master 40 to be written. The batch information and firmware versions can also be stored or updated there during the further production steps.
• b) Production or production data tracking: Serial numbers and other product data are easy to read throughout the life of the product. In the warehouse of the manufacturer or his customers, the data can also be detected through the packaging. Before shipment, if necessary, the serial number can be read through the packaging and recorded in the delivery note. After installing the slave devices in a system, the non-process data from the master 30m , preferably ASi or IO-Link master 30m , scanned via the connection line and the built-in slave devices 10 and also their components, including the software and hardware versions, are documented. When examining returns, the production data can be evaluated, even if the (ASi) slave device interface or the (ASi) slave device 10v should no longer be functional. In this context, counterfeits can also be identified. In the case of recall actions, customers can be addressed in a targeted manner; the customer may be able to determine exactly the installation location of the device to be replaced from his plant documentation. The previous addressing of the ASi slave and commissioning and configuration is quite complicated or cumbersome. In particular, further ASi developments could possibly be in each slave device 10 a unique serial number, vendor ID, device type, and other information put. Here, the early deposit of the serial number and / or the nameplate data is very advantageous.
• c) Device software / firmware update: If the firmware is low, the firmware can be transferred to the device via this interface without the need to develop a minimum operating system or programming adapter. Such devices could also be brought to a new firmware level in the packaging. Alternatively, this interface also offers the possibility of converting devices into a customer-specific device variant by downloading parameter sets shortly before delivery.
• d) Protection against counterfeiting and manipulation: Counterfeits can be identified by encrypted serial numbers and checksums. This check can be carried out with this interface in the warehouse as well as via the PLC of the system manufacturer in the machine. This ensures that always quality and functionally compatible slave devices 10v be used in case of replacement. With returnees, counterfeits can also be detected, often even if parts of the device are no longer functional. In addition, passwords can be specified by a similar mechanism, which is a modification of the slave device 10v about the master 30m or ASi or IO-Link (eg for remote maintenance) only if this is possible locally on the slave device 10v was released via the new wireless interface.
• e) Diagnosis: The dual-channel interface makes it possible at any time, the version of the programmed firmware and other production data wired data serial via the IC (microcontroller or microprocessor) or the slave ASIC and wirelessly via radio using the RFID or NFC read-write device 40 read. This also applies to slave devices with a high degree of protection without having to open them. Messages and states that occur during operation of the slave device 10v can be stored remanently and read later, even after a slave device. 10v Defect if the memory device 20 undamaged.
• f) Communication Parameters: The ASi address of the device 10v can also be read and changed without ASi power supply via the ASi cable (connection cable) supply. At slave devices 10v With several ASi addresses (multi-slave devices), the addresses can be set or changed without process tricks due to their independence from the ASi protocol. In addition, type plate data or device identifier (BMKZ) and other parameters can be set. The same applies to similar single-master-slave systems 50
• g) slave device 10v Parameters: Custom Slave Devices 10v can via the additional data interface in the form of the (RFID / NFC) air interface 21 be produced in the production, or shortly before delivery, by loading special parameters. The setting of new on-site parameters can be done without separation from the master 30m or fieldbus or sensor / actor network locally, so that a manual operating interface, eg push-button 12e - or potentiometer- 12e -Operation in / on the device, often no longer needed. This wireless setting and testing of the parameters is also available with slave devices 10v with high degree of protection and encapsulation possible. A device identifier (BMKZ) enables the user to document the installation location in the device. This feature can be very useful for future ASi developments, as this system is the BMKZ for ASi fieldbus sampling for all slaves or slave devices 10v can read and document.
• h) Create variants: For slave devices 10v Textual user interfaces allow a rarely used national language to be displayed via this interface. Customers can read out parameter sets via this interface and repeatedly import copies of these data sets into their devices (eg in series machines).

In summary, here again the advantages of the invention are listed: The non-process data in the form of the sensor device and / or printed circuit board 1 -specific data can be rewritten, overwritten or read, even if the slave device 10v is de-energized. A check of the stock is easily and reliably possible through the packaging. The energy required for addressing and configuring is very low, since only the RFID transponder or the memory component 20 must be powered via the transponder antenna. The mobile programming tool (Funkmaster 40 ) does not need the slave device for the duration of reading and writing data 10 provide power, which would be technically difficult or very expensive. The manual or mechanical attachment of the serial number (s), lot number (s) or equipment tag on the slave device can be eliminated because it is replaced by low cost electronic attachments that are accessible at each step of the manufacturing process and also made at an extremely early stage can be (after placement of the memory device 20 with the RFID transponder on the slave device 10 conductor interconnection wiring 1 ). Therefore, a complete documentation of the production process by the manufacturer becomes possible.

The manual or mechanical attachment of equipment labels by the plant manufacturer in the installation of the system on the device can be omitted because it is replaced by an inexpensive electronic mounting. In the future, this information can also be used in an advanced ASi system to determine the system state of the ASi slave device 10v from the master 30m be read out and documented. AS-i slave devices 10v can be addressed wirelessly without a mechanical connection to an addressing device. By using antennas with a short range, which also includes the RFID frequency used, the minimum achievable distance of the Tansponder antenna to the RFID reader 40 as a configuration or service device 40 as well as being adjustable via the RFID method used, the unambiguous assignment is also with slave devices mounted side by side 10v possible. At the defect of the slave device 10v In most cases, diagnostic information, parameters and equipment labels can be read from the device, evaluated and used to program the replacement device. Is the capacity of the common volatile memory of the memory device 20 sufficient for parts of the firmware of the device, the programming can be done without programming adapter via RFID. An update is thus possible later without opening the device. Advantageously, multiple and permanently writable non-volatile memories are used. Integration of functionality into the processor or system memory of the slave device 10v is possible and offers potential for cost savings with simultaneous standardization. Since the non-process data transmission is allowed to occur only over a short distance due to the exact location, the antennas can be made relatively small, which is favorable for integration on an ASIC 20 is. By using the non-process data obtained, the master can provide comprehensive diagnostic and communication security information. In addition, it is advantageous to use special slave devices 10v to establish a communication link containing this diagnostic information of the master 30m decentralized. This could be realized via the RFID interface shown in the invention. In addition, however, you can also use the local slave device 10v - Diagnostic data easily via the radio master 40 read.
