The TURCK BL ident® UHF SystemD101831 0713 -  BLident® Installation  of the UHF System142.1 BL ident® – Modular RFID systemBL ident® is a complete RFID system that shows its particular benefits primarily in industrial environments. The modular system is based on the BL67 I/O systems (for field mounting) and the BL20 (for control cabinet mounting) and the BL compact fieldbus modules.Each BL ident® system can be created flexibly with data carriers, read/write heads, connection technology and interfaces (gateways and RFID I/O modules) to form a tailored RFID solution.In addition to high-speed FRAM data carriers offering a virtually unlimited number of read/write operations, high temperature variants for temperatures up to 240 °C are available which can be used for example in paint lines.Another feature: BL ident® can be integrated into existing plant configurations without any problems.2.1.1 BL ident® system conceptThe BL ident® RFID system offers you the flexibility you need for your application on all levels: From the selection of data carriers to read/write heads, right through to the connection to the control level: You always have the possibility to achieve the perfect configuration of the system and to adapt it to your specific requirements. BL ident® is future-proof with interoperability ensured thanks to its compliance with international, global standards. Optimum protection of your investment is therefore guaranteed.2.1.2 BL ident® data carriersEEPROM data carriers with high memory quality and price benefit, particularly with large quantitiesHigh temperature data carriers for comprehensive process control at -40…+240 °CDesigned for direct mounting on metalCustomized solutions through open and globally applicable standards (ISO 18000-6C)2.1.3 BL ident® read/write headsIndustrial and rugged designRead/write ranges up to several meters (UHF)Compact mounting forms for restricted mounting conditions2.1.4 BL ident® interfacesThe BL20 and BL67 modular interfaces as well as the compact BL compact interfaces are available for the BL ident® system. The modular interfaces can be combined from a Standard gateway as well as an RFID interface module of the relevant system. Interfaces for the exclusive connection of read/write heads and also for connecting read/write heads and other field devices such as sensors or actuators are available for BL compactGateways (BL20 and BL67)The gateway connects the fieldbus with the I/O modules and depends on the fieldbus used, unlike the I/O modules themselves. It handles the entire process data traffic and generates diagnostic information for the higher-level controller as well as for the IO-ASSISTANT software. Extended functions are available depending on the type of gateway, such as programmable gateways.

The following base modules are suitable for use in the BL ident® system:Degree of protection IP20 (BL20 system)– BL20-S4T-SBBS (cage clamp terminal) in connection with Standard and ECONOMY gateways.– BL20-S4S-SBBS (screw terminal) only in connection with Standard gateways Degree of protection IP67 (BL67 system)– BL67-B-2M12 (M12 male connector terminal)
Figure 3: Base module for BL20 (left) and BL67 (right)128,912,6The TURCK BL ident® UHF SystemD101831 0713 -  BLident® Installation  of the UHF System16The electronic modules contain the functions of the interface modules (power supply modules, digital and analog input and output modules and technology modules such as RFID modules).They are fitted to the base modules and are independent of the wiring. During commissioning or maintenance, the electronic modules can be removed and fitted without having to disconnect the field wiring.The BL ident® system comprises two types of electronic modules, the BLxx-RFID-S modules (Simple RFID) for simple I/O communication and the BLxx-RFID-A modules (Advanced RFID) for use with function blocks or with programmable gateways.Figure 4: Electronic module for BL20 (left) and BL67 (right)154,512,674,1LED128,9117,673,1LED913277,513145Combination of gateways and interface modulesThe following tables show the possible combinations of BL20 and BL67 gateways with the relevant RFID modules.

The TURCK BL ident® UHF SystemD101831 0713 -  BLident® Installation  of the UHF System222.2.1 Networking with BL ident® UHF systemsBL ident® systems can be integrated in (existing) bus systems, enabling the networking of several  BL ident® systems.The guidelines for the maximum extension of the bus system used apply.A PROFIBUS-DP system can consist of up to 31 stations and a master without the use of repeaters. 2.3 Identification systems with radio frequency technology (RFID)RFID is the acronym for Radio Frequency Identification.An RFID system is composed of a data carrier, a device for reading and writing the data from and to the data carrier, and other devices for transmitting and processing the data. The transmission of the data from the data carrier to the read/write head is contactless using electromagnetic waves. This form of transmission is unaffected by dirt and temperature fluctuations.The data carriers can be attached directly to a product. For this reason the term “mobile data storage” is used. Further terms for the data carrier are TAG or transponder. The data can consist of production and manufacturing data. The data used here to identify the product is of special importance. Hence the term “identification system” is used.The ability to change the data content through write operations to the data carrier offers an additional range of possibilities. This enables the tracing of production/manufacturing processes. Logistics / distribution systems can also be optimized.The identification systems can be integrated into (existing) fieldbus automation systems (such as PROFIBUS-DP). The connection to the fieldbus system is implemented using the appropriate interface modules.Standardized software modules (such as the Proxy Ident Function Block for PROFIBUS-DP) simplify the system integration and commissioning.2.4 Features and application areas of the BL ident® systemIn order to meet the requirements of different application areas, the TURCK BL ident® system offers a host of combination options for data carriers and read/write heads, as well as interface modules for connecting to automation systems (such as PROFIBUS-DP). Software modules enable systems to be integrated and commissioned simply.The following is a list of features of the TURCK BL ident® system:2.4.1 Degree of protectionSome data carriers as well as the corresponding read/write heads come with a high degree of mechanical protection (such as IP67) and can thus also be used in harsh industrial environments.The connection to a fieldbus system is implemented with suitable TURCK interface modules.  The interface modules for CANopen are available with protection to IP20. The identification system is rounded off with TURCK connection cables offering appropriate degrees of protection.Temperature-resistant data carriers up to 240°C are available for high temperature applications.
D101831 0713 -  BLident® Installation  of the UHF System 23Features and application areas of the BL ident® system2.4.2 LifespanThe lifespan is determined by the number of possible read/write operations on the data carriers.EEPROM data carriers can ensure an unlimited number of read operations and 105 write operations.The data carriers do not require any batteries.2.4.3 Transmission frequencyThe TURCK  BL ident® system operates at nationally specified transmission frequencies in the UHF range of (865...928 MHz) between the data carriers and read/write heads. These national frequencies for UHF are required due to the frequency ranges individually specified by the national regulation bodies.UHF systems in this frequency band achieve a higher read/write range than HF systems, typically several meters. The operating frequency of the devices in the UHF band is for example 865…868 MHz for Europe and 902…928 MHz for the USA. The BL ident® read/write heads in the UHF band can therefore only be used in the countries they are intended for and must not be put into operation outside of these regions. As the BL ident® UHF data carriers are passive, and therefore do not radiate their own radiate radio waves, these are suitable for use worldwide. TURCK offers different data carrier variants that are specially designed and optimized for national frequency bands in order to achieve as large a communication range as possible. Wide-band multi-range data carriers for international use are also available as an alternative.The various TURCK read/write heads support the following transmission frequencies:865...868 MHz (e.g. for Europe)902...928 MHz (e.g. for USA and Canada)920…925 MHz (e.g. for China)902...907.5 MHz and 915...928 MHz (e.g. Brazil)917...920.8 MHz (e.g. for Korea)The relevant national specifications for UHF such as frequency range, output and the status of any national regulations can be obtained from the Internet at:http://www.gs1.org/docs/epcglobal/UHF_Regulations.pdfFor more detailed information please contact the relevant authorities of the country where you wish to use the UHF RFID system.
The TURCK BL ident® UHF SystemD101831 0713 -  BLident® Installation  of the UHF System242.4.4 Mounting typesData carriersData carriers for the UHF RFID range are available in different mounting forms and fixing options, and are either optimized for small housing dimensions or large data transmission ranges. Besides the frequency ranges, the selection criteria for the data carriers depend on the application at hand. Data carriers for the direct mounting on metal, for attaching with a metal loop, as well as smart labels and high temperature versions are therefore available in addition to the standard mounting forms. Customized data carrier solutions that are tailored to the relevant application are also available on request.Read/write headsDifferent rectangular mounting forms are available such as compact read/write heads in housings with approx. 175 mm or 240 mm edge length for large data transmission ranges of up to several meters. 2.4.5 MemoryEEPROM data carriers for the UHF range are available with up to 138 bytes memory (110 bytes user data).EEPROM: (Electrically erasable programmable read only memory), non-volatile.The data carriers in the UHF frequency range meet the requirements of the ISO 18000-6C and EPCglobal Class 1 Gen 2 communication standard.2.5 Read/write time in the sensing range of the UHF read/write headThe time that the data carrier must be in the sensing range of the read/write head in order for all the required data to be read and/or written reliably depends on the following factors:Command type (write or read)Data volumeExtent of the sensing range (resulting from the combination of the type of read/write head and the data carrier as well as the environmental conditions)Homogeneity of the electromagnetic field with UHF (interruption of the communication with moving data carriers through field reflections and interference; interaction of radio waves with the environment).The acquisition of data may be disturbed by the following factors:Electromagnetic interference in the relevant frequency bandInterference may cause the cancellation of the waves and fading.
D101831 0713 -  BLident® Installation  of the UHF System 25User data areas of the UHF data carrier variants2.6 User data areas of the UHF data carrier variants2.7 General information on the UHF data carriersThe UHF data carrier memory hierarchy is divided into four logical areas (also called domains) in accordance with ISO 18000-6C and can accommodate several blocks – each block consisting of 2 bytes.CautionPossible damage to the data carriers! Incorrect writing to the reserved area (bank address = 00) or to the first four bytes of the UII memory (bank address = 01) of the data carrier memory may cause the data carrier to permanently malfunction.Bank 00 – reserved range: This area contains the passwords for accessing the memory and for deac-tivating the data carrier. The passwords for deactivating are stored in the memory addresses 00hex to 1Fhex. The passwords for access protection are stored in the memory addresses 20hex to 3Fhex. Memory access to this reserved area is normally executed with separate protocol commands.Bank 01 – EPC (electronic product code) or UII (unique item identifier): This area contains the essen-tial identification data of the transponder. The 16-bit checksum (CRC) is located in the first data word (from address 00hex). The second data word (= 2 bytes) contains specific data carrier control infor-mation (protocol control byte, from address 10hex). The actual data area of the UIIs starts at address 20hex. The data carriers are identified in the BL ident® system by means of the first eight bytes of the data area, i.e. from address 04hex to  0Chex. Bank 10 – TID (tag identification): This area contains one of three values for determining the class identification (E0hex, E2hex or E3hex) in accordance with ISO/IEC 15963, contained in the memory addresses 00hex to 07hex. If the class is ID E0hex, the TID contains a 48-bit serial number.  The composed 64-bit data carrier ID is assigned once within all data carrier classes which are defined in ISO/IEC 15963 and write-protected by the manufacturer. If the class ID is E2hex, the TID  contains a 12-bit data mask identification and a 12-bit data carrier model number defined by the manufacturer. The use of memory addresses above 1Fhex is defined in the EPCglobal data standards, version 1.5 and higher. If the class ID is E3hex, the TID contains an 8-bit manufacturer ID, followed by a 2-byte working memory for different data lengths, the 48-bit serial number, the 1-Bit-XTID and the 15-BIT-XTID header data. The composed 80-bit data carrier ID is assigned once within all data carrier classes which are defined in ISO/IEC 15963 and write-protected by the manufacturer.Bank 11– User area: This area is optional and contains a varying memory range for use as required by the user.

The Impinj Monza® 5 therefore only has three areas (the user area is missing), whilst the NXP-G2XM contains all four areas.2.7.1 Multiple access (multi-tag detection, bulk reading)The data carriers are identified in the BL ident® system by means of the UII. With multi-access these must be different! (multiple access means a read/write head can communicate with different data carriers at the same time. The read/write head can thus address a data carrier selectively by means of its UII.)If the data carriers are factory set with the same UII, these must be individually written with different UIIs before they are used for the first time in applications with multi-access.

D101831 0713 -  BLident® Installation  of the UHF System 35Speed of the data carrier at the read/write head on RFID systems2.8 Speed of the data carrier at the read/write head on RFID systemsThe speed at which the data carrier can move past the read/write head depends on the data volume to be processed, the combination of read/write head and data carrier as well as the spatial conditions of the environment. Specific values for maximum speed and data volume can therefore only be given as examples!The UHF system normally offers a higher read speed than the HF system and many data carriers are detected simultaneously (bulk detection), fast moving data carriers are detected reliably.The processing time of the overall configuration of the identification system must be taken into account as well as the data processing time in the read/write head (“System overview” page 21). The time required for forwarding and processing the data in the overall installation can vary from application to application! If your application is designed for a fast succession of data carriers, it may be necessary to reduce the speed at which the data carriers are moved past the read/write head. In cases of doubt we recommend that you determine the possible speed by trial and error!2.9 Read range / write rangeThe achievable read/write distances depend on the relevant combination of data carrier and read/write head, as well as the spatial physical conditions of the environment. The possible read/write distance depends on the data volume to be written and read as well as the speed at which the data carrier moves past the read/write head. The UHF read/write heads typically have a sensing range of several meters.NoteThe maximum read/write distance of several meters is only an idealized value under laboratory conditions. The achievable distances may be reduced due to component tolerances, mounting location in the application, ambient conditions and the influence of materials (particularly metal and liquids). The parameters for achievable passing speed (read and write operations on the fly) and the maximum transmittable data volume also vary, depending on the actual transmission in the relevant application. Depending on the data carrier, the maximum write distance can be considerably less (e.g.  50 %) than the maximum read distance (see “UHF transmission zone” page 40). A test under actual conditions is therefore always required!
The TURCK BL ident® UHF SystemD101831 0713 -  BLident® Installation  of the UHF System362.10 BL ident® Simulator for UHF-RFID (Ray Tracer)The Ray Tracer is a software simulation tool that enables the functioning of a wide range of different UHF RFID system constellations to be tested in realistic conditions.  Three-dimensional computer models of the RFID application environment and algorithms for calculating the radio wave propagation in the space realistically simulate the operation of UHF-RFID systems. Completing several different simulation runs thus makes it possible to narrow down and preselect suitable system components before the actual installation of the UHF-RFID hardware.  When complex spatial application environments are involved, the Ray Tracer also analyzes the technical feasibility of UHF-RFID radio applications for the spatial structure at hand.Figure 8: Three dimensional, complex computer imaging of an ap-plication environ-mentAll the essential physical factors involved in the propagation of radio waves are taken into account. These include for example: Attenuation characteristics in air and other media (obstacles), reflection and transmission properties on objects of different materials, polarization characteristics, antenna characteristics and gain of read/write units and data carriers.Use of the Ray Tracer requires a considerable amount of training and specialist knowledge, and so it cannot be used by the customer. It is therefore only available for use by TURCK-RFID specialists and their system partners. Contact us so that we can examine the possibility of a simulation, if required for your application. As each simulation is based on actual spatial application conditions, each simulation run is always customer-specific and supplies tailored results for the relevant application site. The information value of these simulation results is often comparable with results gained from actual measurement series carried out on site, and the time and costs involved can be considerably reduced. General and transferable statements cannot be derived from it due to the changing specific physical characteristics of different application sites. Ray Tracer simulations are nevertheless ideal for considerably speeding up the system planning and analysis of UHF-RFID systems, whilst taking customer-specific application conditions into account.

BL ident® System – PlanningD101831 0713-  BLident® Installation of the UHF System403.1 Selection criteria for data carriers, read/write heads and interface moduleIn order to make the right selection of BL ident® system components, the application should be assessed according to the following criteria:Mechanical dimensions,Distance of data carriers to read/write heads for read and write operations,Tolerances in the mechanical guidance/motion within the transmission zone,Static and/or dynamic transfer of data,Data volume to be transferred,Speed of dynamic read and write operations (on the fly),Attenuation characteristics in air and other media (obstacles), reflection and transmission properties on objects of different materials,environmental conditions such as hazardous areas, humidity, temperature, effect of chemicals etc.The following selection criteria apply in particular to read/write heads:Mechanical dimensions,Region of use (Europe, USA ... etc.),Size of the data carrier used,The following criteria must be particularly taken into account when using the interface modules:Degree of protection,Bus type,Number of channels.3.2 Transmission zone and read/write distanceUHF technology makes use of the properties of a radiated electromagnetic wave.  The recommended read/write distances depend on the combination of data carrier and read/write head, as well as the spatial physical conditions of the surroundings. The distribution of the radio field depends on the type of antennas in the data carrier and the read/write head, as well as the layout and characteristics of the spatial environment (e.g. reflecting obstacles).3.2.1 UHF transmission zoneAs with HF RFID, the size of the UHF transmission zone also depends on the combination of data carrier and read/write head. However, the shape and the extent of the transmission zone is primarily determined here by external environmental factors. As the electromagnetic waves in the UHF band have a larger range, obstacles in the spatial environment of the read/write head, as well the data carrier play a major role. Metallic objects or objects with a high permittivity in particular change the spatial field distribution of the reflected and transmitted radio waves, and thus the condition of the data transmission zone in the air.  Obstacles that are not located directly in the connection line between data carrier and read/write head, but for example at the side or rear, also have an effect. The transmission zone can take on a more or less jagged shape – with fading inside it.
D101831 0713-  BLident® Installation of the UHF System 41Transmission zone and read/write distanceReserve transmission distances should be allowed for in planning in order to ensure safe operation. Depending on the mounting conditions, this means for example, that only approx. 40 ... 80 % of the maximum possible distance Dread_ideal  is actually used for read operations based on the maximum possible read distance Dread_ideal for a particular combination of read/write head and data carrier. The possible distance for a write mode may be even less, e.g. only 50 % of the possible read distance Dread_ideal.Figure10: Possible read/write distancesDread_ideal Dread_real_max Dwrite_maxca. 40…80 %ca. 50 %100 %Reserve capacity must be included in planning, not only with regard to the possible radio range, but also with regard to time available for accessing the data carrier on the fly within a time window.NoteAppropriate range tests in real conditions must be carried out in all cases!3.2.2 Minimum distance of data carrier to the read/write headWith BL ident® a minimum distance between the data carrier and the read/write head is not necessary.3.2.3 Permissible motion direction and alignment of the data carriersThe data carriers can move over the read/write head in any direction. It is only necessary for the data carriers to be aligned parallel to the read/write head..NoteThe TN…Q240L280… can either be set for linear or circular polarization via the WebConfig software tool! If linear polarization is selected, the data carrier has to be directed in horizontal or vertical direction.
BL ident® System – PlanningD101831 0713-  BLident® Installation of the UHF System423.2.4 Reading and writing in static modeIn static mode, the data carrier is located in a fixed positioned precisely in front of the read/write head. Unlike HF, UHF allows use up to a greater distance of several meters. In this mode, the processing of a large number of data carriers is possible, however, due to the inhomogeneous UHF field, several transfer attempts may be necessary, and the data carriers may not even be detected in this mode as they are located in a dead zone.NoteReading and writing in static mode is therefore not recommended!3.2.5 Reading and writing in dynamic mode (on the fly)In on the fly mode, the data carrier moves according to the configuration at a transverse speed past the read/write head.  This mode is preferred for the processing of a large number of data carriers, however several transfer attempts may be necessary due to the inhomogeneous UHF field. An additional time reserve for detecting all data carriers must therefore be included in planning.There is also the risk of fading, by which communication with the data carriers may fail and the data carriers may possibly not be detected.3.2.6 Transfer rateThe transfer speed in the UHF band may vary depending on the data carrier and the transmission process used. It is therefore not possible to provide a general calculation formula. However, the transfer speed is generally higher than for HF (ISO 15693).3.2.7 Range difference between reading and writingThe difference primarily depends on the data carrier. Depending on type and mounting location, the range for write operations may only be 30…50 % of the maximum range for read operations in the same conditions (see also “UHF transmission zone” page 40).NoteTURCK recommends that write operations in an application are not carried out close to the limit of the transmission zone.3.2.8 Minimum distance between two adjacent data carriers in single modeIn dynamic mode (on the fly) the minimum distance of successive data carriers depends on the data volume and the bus cycle time.NoteAppropriate tests to determine the minimum distance of successive data carriers must be carried out before startup.
D101831 0713-  BLident® Installation of the UHF System 43Transmission zone and read/write distance3.2.9 Minimum distance between two adjacent data carriers in multiple accessMultiple access means a read/write head can communicate with several data carriers at the same time. The read/write head can thus address a data carrier selectively by means of its UII/EPC.In order to access several data carriers located at the same time within the wireless sensing range of the read/write head, as large a distance between the data carriers should be selected as possible. The minimum distance between the data carriers should be 50 mm. If the data carriers are located close together, it may not always be possible to ensure successful identification via the communication in the air interface.NoteInformation about the expected performance must be determined by carrying out a function test under specified application conditions.Multiple access requires that all the data carriers involved are located at the same time in the radio field of the relevant read/write head. As this is not always possible due to interference in the environment (e.g. radio reflections) and the spatial distance and arrangement of the data carriers, as well as the need for additional modifications in the application process such as:modifications to the arrangement of the data carriers,changing from static mode to dynamic mode,applications that only access a single data carrier at the same time are often easier to implement.3.2.10 Dwell time Td of the data carrier The dwell time Td is the time in which the data carrier is in the sensing range of the read/write head on passing. During this time the read/write head can exchange data with the data carrier.In static operation, the dwell time can either be as long as required or zero if the data carrier is located in a dead zone due to interference in the environment.  However, the dwell time must be at least as long as necessary to complete communication with the data carrier.In dynamic mode, the dwell time is determined by the system environment. The dwell time must be adapted to the transferred data volume. Conversely this means that the shorter the dwell time, the smaller the data volume that can be transferred.However, with UHF there is a risk of fading, in which communication with the data carriers can fail. Several transfer attempts may therefore be necessary to establish communication due to the inhomogeneous UHF field.  The dwell time should therefore allow for enough additional time for further retries.NoteThe number of automatic retries can be set via the offline parameters of the higher-level controller (PLC).

Mounting and operating guidelinesD101831 0713 -  BLident® Installation of the UHF System464.1 Effect on the performance of the BL ident® systemThe following important points should be taken into account during design and installation:Minimum / maximum distance between read/write headsMinimum distance of read/write heads to conductive materialsMinimum distance between two adjacent data carriers Interaction when using several read/write headsBehavior of electromagnetic waves in the UHF rangeParameter assignment of the read/write heads, such as setting the transmission output, operating frequency and RF transmission parameters via the DTM or the RDemo and WebConfig software tools4.1.1 Minimum / maximum distance between read/write headsThe distance between two read/write heads mounted next to each other depends on the transmission output, i.e. the lower the transmission output, the smaller the minimum distance possible. At least 20 cm should be selected as a guide value, and a distance of 50 cm or greater is recommended.Figure 11: Minimum distance between two read/write heads mount-ed next to each oth-er20...50 cmWith a portal configuration, the maximum distance between two read/write heads is 3.5 m.Figure 12: Maximum distance for portal configu-rationEurope   max. 3,5 mUSA, China max. 4,0 m
D101831 0713 -  BLident® Installation of the UHF System 47Effect on the performance of the BL ident® system4.1.2 Minimum distance of read/write heads to conductive materialsA minimum distance of the read/write heads to conductive materials should be observed due to the detuning of the read/write heads through a conductive environment.The following minimum distances must be observed when mounting read/write heads:A minimum distance of 50 cm must be observed between a read/write head and liquids or metals.The distance between the read/write head and the ground must also be at least 50 cm.Figure 13: Minimum distances for mounting read/write headsmin. 50 cmmin. 50 cmmetalgroundliquidNoteThe effect of interference produced by conductive material in the environment on the radio field of the read/write head, and which may cause detuning, can be compensated using the two RDemo and WebConfig software tools.  The read/write head should first of all be tuned with the RDemo software tool via the Antenna tuning function so that the effect of interference on its performance is sufficiently suppressed.  If this does not produce the desired result, you should try to compensate the detuning in the next step by using the Auto tuning function which can be activated in the WebConfig software tool after a specific firmware of the read/write head (see the following “Table 14: Firmware versions for read/write heads that support “Autotuning””). This function enables the cyclical, automatic tuning of the radio field in response to the effects of ambient interference; this reduces the operating range of the radio field.Table 14: Firmware ver-sions for  read/write heads that support “Au-totuning”Read/write head from firmware versionTN…-Q240 L280-H1147 1.33TN…-Q175 L200-H1147 1.39TN…-Q120L130-H1147 1.39
Mounting and operating guidelinesD101831 0713 -  BLident® Installation of the UHF System484.1.3 Minimum distance of data carriers to conductive wallsA distance of 20...200 mm is recommended if conductive walls and obstacles are present in the environment that shadow the radio field. The effect of walls is minimized in all cases if the polarization axis is orthogonal to the wall. Figure 14: Minimum distances of data carriers to a conductive wall, polarization axis or-thogonal50...200mmpolarization axisconductive wallA minimum distance to a conductive wall must be observed for the data carriers.

It must therefore be ensured that the data carrier is only read by the appropriate read/write head. Technical malfunctions between read/write heads will particularly occur if the read/write heads transmit on the same channel (on the same frequency).There are different methods to prevent this with BL ident®. For example, TURCK read/write heads in Europe use “adaptive frequency agility” (ETSI 302 208 V1.2), and in China, Korea and the USA, the frequency hopping procedure (FCC Rules Part 15). Adaptive frequency agilityIn order to exclude signal collision, the read/write head using adaptive frequency agility checks before transmitting whether the four receive channels adjacent to the transmit channel concerned (two above and two below the transmit channel) are free. The read/write head only transmits if the adjacent channels are free. The read/write head must transmit up to four seconds on the channel and must then either make a pause of at least 100 milliseconds or jump to a free channel and transmit on this channel for four seconds.Frequency hopping procedureWith the frequency hopping procedure used in the USA and China, the read/write head changes its transmit channel in a random or programmed sequence (FHSS – frequency hopping spread spectrum). With 50 channels (USA) and 16 channels (China) available, there is a low probability that two read/write heads are operating on the same frequency.
Mounting and operating guidelinesD101831 0713 -  BLident® Installation of the UHF System50Other ways of preventing the interaction between read/write heads are:Observe the necessary minimum antenna distances according to their alignment The necessary minimum distance between the read/write heads using the same frequency depends on the set effective radiant power and the alignment of the antenna.Figure 19: Antenna alignmentTag TagTagTagTag TagDDDTable 15: Antenna distanc-es with the same frequencyAntenna align-mentsee “Figure 19:”Required minimum antenna distance = D forTN…-Q240 L280-H1147with ERP = 2 WRequired minimum antenna distance = D forTN…-Q175 L200-H1147with ERP = 1 WRequired minimum antenna distance = D forTN…-Q120L130-H1147with ERP = 0.5 WBack to backarrangement1 m 0.5 m 0.25 mSide by side 2 m 1 m 0.5 mAntenna facing each other5 m 2.5 m 1.25 mNoteThe stated values do not take into account the effect on the data carriers.Use Dense Reader Mode (DRM) for applications in Europe The special DRM = Dense Reader Mode for BL ident® read/write heads enables several read/write heads in close proximity and using one and the same frequency to operate fault-free.  In accordance with EPC Global and ETSI EN 302 208 V1.2.1, transmission is implemented on the four transmit channels and the data carrier response appears on the associated adjacent channels. Due to the large difference in signal levels between the transmit channels and the data carrier response channels, this technique offers significant benefits when frequencies are reused. However, this requires the observance of minimum  distances and thus a minimum decoupling between the antennas of adjacent read/write heads.
NoteWhen the read/write heads are used in Europe, the use of DRM filters is advantageous if several read/write heads are operated in a narrow space. These DRM filters can be switched on manually in the WebConfig software in the Link profiles menu.D101831 0713 -  BLident® Installation of the UHF System 51Effect on the performance of the BL ident® systemSynchronize read/write heads using a higher-level controller In order to minimize the interference between read/write heads, their mode should be as synchronized as possible, e.g. via a central controller (PLC), or the TDMA procedure should be used for the transmission. If possible there should always only be one read/write head active for read or write modes and its activation time should be at a minimum.Trigger read/write heads In order to minimize the operating time of the radio field to the time required for communication with the data carrier, the read/write heads should if possible only be triggered on, for example, by means of an additional switch sensor that only activates the radio field if the data carriers are in the sensing range of the read/write head.Create a channel assignment plan TURCK recommends the creation of a channel assignment plan for RFID applications in Europe. For this the read/write heads using the same channel in a spatial environment (e.g. machine hall) should be located as far apart from each other as possible  (see “Table 15:”).The following frequency ranges with the associated channels are used in Europe, Korea, the USA or China:Figure 20: Frequency ranges in Europedata carrier response865.0 865.7 866.3 866.9 867.5 868.0600 kHz 200 kHzread/write signalmax. 2.0 W (ERP)     f [MHz]NoteFor applications in Europe, the read/write heads should be assigned to and use equally the four channels provided, i.e. when using, for example, 5 read/write heads, not all of them should run on channel 4 whilst channels 7, 10 and 13 remain free.

D101831 0713 -  BLident® Installation of the UHF System 53Effect on the performance of the BL ident® systemSet the transmission output and possibly other read/write head parameters In order to reduce the mutual interference between components in the application, a practical transmission output setting and if necessary other read/write head parameters should be ensured, for example, via the DTM or the RDemo and WebConfig software tools.Use mechanical shielding If necessary, TURCK also recommends the use of mechanical shielding, such as mesh grills as a further measure to reduce interference, such as the faulty and unintended detection of data carriers positioned further away.4.1.7 Factors influencing the read distanceThe read range between the read/write head and the data carrier is influenced by the following factors:Transmission output of the read/write head:  The higher the transmission output, the greater the read distance.Size and design of the data carrier:  The larger the antenna of the data carrier, the greater the energy consumption and therefore the greater the read distance.Absorption factor of materials:  The greater the absorption of the materials in the environment, the smaller the read distance.Reflective properties of the environment: In a multi-reflective environment (e.g. in rooms with reflective surfaces, machines, concrete walls) the read distance can be considerably higher than in an environment with low reflective properties.Fading is possible!Data carrier frequency tuning: Data carriers optimized for specific regions such as with the 865…868 MHz frequency band for Europe, normally offer in this region higher read distances than data carriers designed with a broad frequency band such as 860…960 MHz.4.1.8 Environmental conditions for data carriersThe data carrier must not be placed directly on metal surfaces or on liquid containers. This does not apply to specially designed data carriers which can be mounted directly on metal. The possible read/write distance can nevertheless be reduced! A minimum distance between the data carriers and conductive material must be ensured due to the physical factors involved. A minimum distance of 5 cm is recommended. However, a greater distance (between 5 and 20 cm) is recommended.Liquids such as water and aqueous substances, ice, carbon have a higher RF attenuation in the UHF band. The electromagnetic energy is partly reflected and absorbed so that the data carrier must not be mounted directly on containers of liquid.The mounting of a data carrier on a non-conductive material (plastic, wood) is normally less critical than mounting on material with low conductivity.NoteAppropriate range tests in real conditions must be carried out in all cases!
Mounting and operating guidelinesD101831 0713 -  BLident® Installation of the UHF System544.1.9 Data carrier orientation in the roomThe orientation of the data carrier antenna to the antenna of the read/write head determines the read range.In order to achieve optimum performance and maximum read range, the data carrier antenna must be aligned parallel to the read/write head.Figure 24: Parallel data carrier alignmentIf the data carrier antenna is aligned vertically to the read/write head, this will only result in poor performance and a minimum read range. Vertical alignment should therefore be avoided.Figure 25: Vertical data carrier alignment
D101831 0713 -  BLident® Installation of the UHF System 55Behavior of electromagnetic waves in the UHF range4.2 Behavior of electromagnetic waves in the UHF range4.2.1 Effect of reflections and interferenceReflections and interferenceElectromagnetic waves in the UHF range behave and are propagated in a similar way to light waves, i.e. they are reflected on large objects such as ceilings, floors, walls, windows and interfere with each other. Due to the nature of electromagnetic waves interference may cause wave amplification, which will increase the read range. In unfavorable circumstances, interference may also cause wave cancellation and therefore lead to fading.Due to these electromagnetic properties in a multi-reflective environment as they occur in the actual environment onsite, it is difficult to determine in advance the propagation paths and field strength for a particular location.NoteAppropriate range tests in real conditions must be carried out in all cases!Reducing the effect of reflections/interference on data carrier detectionReduce transmission output:In order keep interference to a minimum, we recommend reducing the transmission output of the read/write head so that it is sufficient for a detection rate of 100 %.Synchronize read/write heads through a higher-level controller:The operation of the read/write heads between each other should be synchronized as much as possible, for example using a central PLC, in order to minimize the interference between them.4.2.2 Effect of liquids and non-metallic substancesNon-metallic substances can also affect the propagation of electromagnetic waves. If non-metallic substances/bodies that absorb UHF radiation are present in the propagation field, this can change the field or cause the cancellation of the field depending on the size and distance involved.Liquids and aqueous substances, ice, carbon have a higher RF attenuation in the UHF band. The electromagnetic energy is partly reflected and absorbed.Oil and petroleum-based liquids have low attenuation properties. Electromagnetic waves penetrate these liquids and are only slightly attenuated.4.2.3 Effect of third party componentsThe R&TTE directive and the relevant standards stipulate the requirements for electromagnetic compatibility. This includes third party components of the BL ident® system. Although the requirements for electromagnetic compatibility are defined, different components nevertheless produce mutual interference.The performance of the BL ident® system very much depends on the electromagnetic environment of the read/write heads.Reflections and interferenceElectromagnetic fields of the read/write head are weakened by absorbing materials and reflected by conductive materials. If electromagnetic fields are reflected, the reflecting fields and the fields of the read/write heads produce overlays (interference).
Mounting and operating guidelinesD101831 0713 -  BLident® Installation of the UHF System56Third party components in the same frequency bandThird party components may possibly transmit in the same frequency band as the read/write head.  Alternatively, the third party components may transmit in other frequency bands with side bands that overlap the frequency bands of the read/write head. This may cause a decrease in the signal-to-interference ratio, thus reducing the performance of a BL ident® system.

EMC GuidelinesD101831 0713 -  BLident® Installation of the UHF System626.1 Target groupThese EMC guidelines are aimed at:Design engineers and planners involved in the planning the installation with the RFID modules to be configured.Fitters, service technicians and engineers using this description to ensure the proper installation of the connection cables or having to rectify faults if interference is present.This chapter provides more information about the EMC guidelines, particularly:Propagation of electromagnetic interferenceDefinition of EMCBasic rules for ensuring EMC,Installation in a control cabinet,Preventing interference sources,Equipotential bonding,Shielding the cables.6.2 Propagation of electromagnetic interferenceElectromagnetic interference can only occur in an installation if the following elements are present:Interference source,Coupling path,Interference sink.Interference cannot occur if one of these elements is missing (such as the coupling path), even if the interference source has strong interference emissions (“Figure 26: Interference components” ):Figure 26: Interference componentssource of interferencee.g. motorsusceptible equipmente.g. read/write headlinke.g. cable connectorThe measures to prevent interference (EMC measures) are applied to all three elements.  When designing an installation, the manufacturer must take all possible measures to counteract the occurrence of interference sources.The installation must also be implemented in such a way that the mutual interference of the individual elements is prevented or is kept as low as possible.
D101831 0713 -  BLident® Installation of the UHF System 63RFID interference6.3 RFID interferenceProblem: Radiated interference via the current supply through the use of power supply units. Remedy: Use a stabilized power supply unit.Problem: Interference via the serial connection cable. Remedy: Improved cable shielding and/or grounding of the read/write head.Problem: HF interference via the antenna through another RFID read/write head.  Remedy:  Position the antennas further apart from each other or change the alignment of antennas to each other. Install suitable damping materials between the antennas. Reduce the power of the read/write heads.Problem: HF interference via the antenna through a different wireless system that is transmitting in the same frequency band. Remedy: For example a change of channel can provide a remedy, depending national radio regulations. Coupling pathsThere are four types of interference coupling:Galvanic coupling,Capacitive coupling,Inductive coupling,Radiative coupling.This interference coupling has different causes:On cables and lines:Incorrect our unfavorable cable routing,Missing or incorrectly connected shield,Spatially unfavorable cable arrangement.With control cabinets or housings:Missing or incorrectly wired equipotential bonding,Missing or incorrect grounding,Spatially unfavorable arrangement,Insecurely mounted modules,Unfavorable control cabinet layout.6.4 EMC – DefinitionThe electronic elements of an installation are increasingly exposed to interference due to the increasing density of installed components, the increasing amount of power electronics connected and the faster switching speeds involved. The is always subject to the following principle: The higher the degree of automation, the greater the risk of mutual interference.Definition of EMC:“By electromagnetic compatibility (EMC) is meant the ability of an electrical or electronic device to operate satisfactorily in an electromagnetic environment without affecting or interfering with the environment over and above certain limits.”
EMC GuidelinesD101831 0713 -  BLident® Installation of the UHF System64As the RFID modules are only components within an overall system and may produce new interference sources through the combination of various components, the design of an installation must comply with specific regulations.The interference immunity of an installation requires the implementation of a complete package of measures; in this case, the operator is responsible for the RFI suppression of the entire installation. This person must also observe the relevant national specifications and regulations. All measures that are implemented when the system is installed will save expensive modifications and fault rectification measures made later.6.5 Basic rules for ensuring EMCObserve the following basic rules to ensure electromagnetic (EMC):Shielding through housing Protect the device from external interference by installing it in a cabinet or housing. The cabinet or the  housing must be integrated in the chassis ground. Shield electromagnetic fields of inductive loads from the device using partition plates. Use metal connector housings for shielded data transmission cables.Large-area ground connection Connect all passive metal parts to the chassis ground using an HF low impedance connection across a large area. Establish a large-area connection between the passive metal parts and the central grounding point. Incorporate the shield ground in the chassis grounding system, i.e. the shield ground must be connected to chassis ground with a large-area connection.Planning the cable installation Break the cabling down into cable groups and install these separately. Always route power cables and data cables in separate ducts or in separate bundles. Feed the cabling into the cabinet from one side only and, if possible, on one level only. Route the data cables as close as possible to chassis surfaces. Twist the feed and return conductors of separately installed cables. In many cases, a separate cable duct for the bus cable is provided anyway. Ideally this should likewise be used for laying the data cables between the read/write heads and the interface modules.Shielding the cables Shield the data transmission cables and connect the shield at both ends. Shield the analog cables and connect the shield at one end, e.g. on the drive unit. Always apply large-area connections between the cable shields and the shielding bus at the cabinet entry and fasten with a low impedance contact using clamps. Feed the connected shield through to the module without interruption. Use braided shields, not foil shields.Line and signal filters  Use only line filters with metal housings. Connect the filter housing to the cabinet chassis using a HF low impedance large-area connection. Never fix the filter housing to painted surfaces. Fix the filter at the control cabinet entry or in the direction of the interference source.
D101831 0713 -  BLident® Installation of the UHF System 65Basic rules for ensuring EMC6.5.1 Installation in a control cabinetMagnetic and electrical fields and electromagnetic waves can be kept away from the interference sink by using a metal housing. The easier the induced interference current can flow, the greater the intrinsic weakening of the interference field. All housings and metal panels in the cabinet should therefore be connected with a low impedance connection. If the control cabinet panels are insulated from each other, an HF low impedance connection can be established using ribbon cables and HF terminals or HF paste (the larger the area of the connection, the better).Interference can also be prevented through optimum control cabinet design.  In this case the following applies as a general rule:The effect of the interference decreases as the distance between the interference source and interference sink increases,The interference can be further decreased by installing shielding plates,Signal cables should have a minimum clearance from power cables or load cables of 10 cm.Interference from the power supply should be prevented through the installation of line filters. Ensure that the line filter is correctly rated and is mounted directly at the cabinet entry.6.5.2 Preventing interference sourcesPrevent the installation of interference sources that particularly occur with switched inductances.Relays, contactors, fluorescent lights in the control cabinet and valves are particular sources of interference, which can be prevented through the use of RC circuits, free-wheeling diodes etc. This also prevents stray interference on conductors installed parallel to the coil conductors.6.5.3 Equipotential bondingPotential differences between different parts of a plant can arise due to the different design of the plant sections and different voltage levels. Equalizing currents then flow across the signal cables (the equipotential bonding must not be confused with the protective ground conductor).Proper equipotential bonding is therefore essential. The following points must be observed:The equipotential bonding conductor must have a sufficiently large cross section (at least 10 mm2)The distance between the signal cable and the associated equipotential bonding conductor must be as small as possible (antenna effect)A fine-strand conductor must be used (better high-frequency conductivity)When connecting the equipotential bonding conductors to the central equipotential bonding strip (EBS), the power components and non-power components must be combinedThe equipotential bonding conductors of the individual modules must lead directly to the equipotential bonding strip.The better the equipotential bonding in an installation, the smaller the chance of interference due to fluctuations in potential. Equipotential bonding should not be confused with the protective grounding of an installation. Protective grounding prevents the occurrence of excessive shock voltages in the event of equipment faults whereas equipotential bonding prevents the occurrence of differences in potential.
EMC GuidelinesD101831 0713 -  BLident® Installation of the UHF System666.5.4 Shielding the cablesSignal cables must be shielded in order to prevent the coupling of interference. The best shielding is achieved by installing the cables in steel tubes. However, the use of cables with braided shields is normally enough. In either case, however, correct connection is vital for effective shielding, since an unconnected or incorrectly connected shield has no shielding effect.The following always applies:Since interference signals are frequently within a range > 10 kHz, a large-area shield connection is necessary,The shielding bus should be connected to the control cabinet housing using a low impedance connection across a large area and must be situated as close as possible to the cable entry. The cable insulation must be removed and the cables clamped to the shielding bus with an HF clamp or secured using cable ties,The shielding bus must be connected to the PE railIf shielded cables have to be interrupted, the shield must be continued via the connector housings of suitable male connectors,If intermediate connectors are used, which do not have a suitable shield connection, the shield must be continued by fixing cable clamps at the point of interruption.

BL ident® – Data carriers for the UHF bandD101830 0713 -  BLident® Installation of the UHF System687.1 FunctionThe BL ident® data carriers are suitable for non-contact read and write operations with the appropriate read/write heads. The operating frequency in the UHF band is between 865 MHz and 928 MHz, depending on the region where the system is to be used. Different transmission distances are possible, depending on the dimensions of the data carrier and therefore the dimensions of its dipole antenna. The following applies as a general rule: The smaller the data carrier and therefore also the antenna, the shorter the distance. The mounting forms are available as EEPROM memory variants. The BL ident® data carrier essentially consists of a microchip with an integrated memory and dipole antenna. (“Figure 27: Block diagram of a data carrier”).Figure 27: Block diagram of a data carrierUBmodulatordemodulatorcontrol logicsmemory7.1.1 Memory moduleThe information on the data carrier can be read – however it is also possible to add new data (read/write). The size of the memory varies according to type and is in all between 28 bytes and 138 bytes.The memory module consists of the following components:EEPROM: Unlimited reading but limited write cycles (105) possible. No battery required.The data retention time of the memory is: 1 year at 85 °C10 years at 55 °C120 years at 25 °CElectrical fields cannot erase the memory as their field strength is normally too low and these fields do not resonate due to the frequency tuning.7.1.2 Data carrier antennaUHF data carriers normally have similar reception characteristics to a dipole antenna with a linear polarization. Depending on how the data carrier is fitted, horizontal, vertical or mixed polarization is used.
D101830 0713 -  BLident® Installation of the UHF System 69Type overview of the data carriers7.2 Type overview of the data carriersThe RFID operating frequencies in the UHF band are subject to national specifications, for example 865...868 MHz in Europe and 902...928 MHz in the USA. TURCK offers different data carrier variants that are specially designed and optimized for national frequency bands in order to achieve as large a transmission range as possible. Wide-band multi-range data carriers for international use are also available as an alternative. Besides the frequency ranges, the selection criteria for the data carrier depend on the application at hand. Data carriers for the direct mounting on metal, for attaching with a metal loop, as well as smart labels and high temperature versions are therefore available in addition to the standard mounting forms. Customized data carrier solutions that are tailored to the relevant application are also available on request.Table 16:  Type overview of the data carriersDimensions/housing lengthMemory size[Byte]Memory Operating tempera-ture[° C]Special featuresType designation28,5367ø 2,522112 EEPROM -40...+85 Designed exclusively for direct mounting on metal,high temperatureTW865-868-Q22L36-M-HT-B112275,527ø 3,4ø 7,4112 EEPROM -20...+80 Designed exclusively for direct mounting on metal,TW865-868-Q27-M-B112TW902-928-Q27-M-B112141260110 EEPROM -35...+85 Suitable for direct mounting on metalTW865-868-Q14L60-M-B110TW902-928-Q14L60-M-B110

BL ident® read/write heads for the UHF bandD101831 0713 -  BLident® Installation of the UHF System748.1 FunctionThe BL ident® read/write heads (transceivers) are used for non-contact data exchange with the appropriate data carriers (tags). The UHF read/write heads form a transmission zone for which the size depends on the combination of read/write head, data carrier and the relevant ambient conditions. The maximum read/write distances only represent typical values under laboratory conditions without the effect of materials.The achievable distances may be different due to component tolerances, mounting location in the application, ambient conditions and the effect of materials (particularly metal and liquids).NoteFor this reason, the application must be tested (particularly with read and write operations in motion) under real conditions! The operating frequency in the UHF band is between 865 MHz and 928 MHz, depending on the region where the system is to be used.  The read/write head consists of an electronic unit and an antenna. (“Figure 28: Block diagram of a read/write head”)Figure 28: Block diagram of a read/write headModulatorDemodulatorGenerator8.1.1 Read/write head antennaThe antenna is a radiating element with different designs and properties depending on type. It is used for transferring data between the data carrier and the read/write head. If the alignment of the data carriers is unknown, or an alternating alignment is expected, the antenna should have a circular polarization. Circular polarization is either left-hand or right-hand circular polarization (LHCP and RHCP). When using read/write head antennas with linear polarization, ensure that the antenna and the data carrier have identical polarization (e.g. vertical or horizontal).  Due to the operating principle, no special requirements need be observed to suppress the orthogonal components (cross-polarization).The antenna polarization of the TN…-Q240L280-H1147 read/write head can also be preselected via the WebConfig software tool. Depending on the application, it is therefore possible to set polarization to LHCP, RHCP, vertical and horizontal during the startup.

A bus can be composed of a number of parallel cables (addressing, control and power supply) for data transmission.Bus systemThe totality of all units that communicate with one another via a bus.CCCPUAcronym for “Central Processing Unit”. Central unit for data processing, the core of a computer.DdBmThe power level LP (L = level, P = power) is defined in dB as follows: dB (decibel) is the unit of the power level LP that describes the ratio of a power value P1 in comparison to a reference power value P0. If the reference value is 1 mW (milliwatt) the measured value is stated in dBm (m = milliwatt).LP = 10 log(P1/P0) with P0 = 1 mW => LP (dBm) = 10 log(P1/1 mW) and conversely, if the power is required in mW:P1(mW) = 10(Lp(dBm)/10)DistributionDistribution comprises all activities related to the transfer of goods between economic entities.DINGerman acronym for German Industrial Standard.DP master class 1The automation system (PLC) which is mainly responsible for the cyclical processing of process data. The  “DPV1” functions can be employed additionally / optionally. (also DPM1/DPC1).DP master class 2Exclusive transmission of acyclical demand data. This data transmission can be carried out, for example, using an engineering tool (PC application program).DPV1Functional extension to PROFIBUS-DP. In addition to the cyclical process data, demand data can be transmitted via acyclical communication functions. The acyclical services are conducted at the same time and in addition to the cyclical process data transmission with lower priority.EEEPROM - Electrically Erasable Programmable Read-Only MemoryEEPROM is the name given to a non-volatile, electronic memory module. An EEPROM consists of a field effect transistor matrix with an insulated floating gate, in which each transistor represents a bit.
GlossaryD101831 0713 -  BLident® Installation of the UHF System84EMCElectromagnetic compatibility (EMC) denotes the normally desired state in which technical devices do not cause or suffer undesired electrical or electromagnetic interference to or from other devices in the same environment.EPCThe electronic product code (EPC) is an international code system for a unique identification number, by which products, stock-keeping units (outer packaging, transport pallets etc.), systems, services, documents, reusable transport containers and locations (e.g. buildings (sections) or warehouse sites) can be uniquely designated and identified. In combination with RFID technology it can be used for the detection and tracing of objects fitted with a transponder with EPC without visual or physical contact.EPC enables the unique identification of objects by class or type (e.g. a GTIN) and instance (in this case, a serialized GTIN[1]) (e.g. commercial unit, stock-keeping unit or transport container). For this the EPC is stored on a data carrier which is fitted to the object to be identified. An RFID chip in compliance with ISO 18000-6C is normally used as a data carrier to store and transmit the code. GroundIn electrical engineering, the name given to a conductive area with an electrical potential of zero at any point. The electrical potential of the ground may not equal zero in the area around grounding devices, in which case this is called the “reference ground”.GroundingThe connection of an electrically conductive component to the ground using a grounding device.Grounding deviceOne or several components that have direct and good contact with the ground.ERP/EIRPThe effective radiated power (ERP) is the product of the power supplied in the transmitting antenna multiplied by the antenna gain (referenced to a half-wave dipole). If no direction is stated, the value applies to the main direction of radiation from the transmitting antenna where its greatest antenna gain is present at the same time. If the antenna gain is referenced to the isotropic antenna, it is called EIRP (Effective Isotropic Radiated Power).FFieldbusData network on the sensor/actuator level. A fieldbus connects the devices on the fieldbus level with a control device. A fieldbus offers high transmission security and a real-time behavior.Frequence hoppingThis procedure is designed to prevent mutual interference between read/write heads. For this the read/write head changes its transmitting channel according to a random or programmed sequence (FHSS). With 16 channels that are permitted for simultaneous operation in China and 50 channels in the USA, this reduces the probability that two read/write heads are operating on the same frequency.GGSD - General Station Description(previously device master file) The GSD file describes the characteristics of the devices used in PROFIBUS-DP. The GSD file is a readable text file and is supplied in different languages. Configuration tools require the device information in order to complete the configuration and commissioning. The GSD file normally contains general information (e.g. vendor name and version) and with modular devices the communication features (e.g. module designations, texts for diagnostic messages, parameter options, parameter names) of the individual modules. HHexadecimalNumerical system with a base of 16. The sequence begins with 0 to 9 and continues with the letters A, B, C, D, E and F.
D101831 0713 -  BLident® Installation of the UHF System 85IEC 61131LIIEC 61131 is an international standard that covers the basic requirements of programmable controllers.InitializationDuring initialization, the memory space is reserved and filled with initial values (such as variables, code, buffer, ...) required for the execution.IP - International ProtectionThe degree of protection (IP) specifies the suitability of electrical equipment (such as devices, installation material) for different environmental conditions in addition to the protection of persons from potential hazards during use.CConfiguringSystematic arrangement of the I/O modules of a station.LLSBLeast significant bit. Bit with the lowest numerical significance.LogisticsLogistics is the science of the overall planning, control, implementation, provision, optimization and monitoring of processes for the relocation of goods, data, energy and persons, as well as the necessary methods of transport. MMasterIn a master-slave process on the fieldbus, the master controls the access relationships.ModeOperating mode.MSBMost significant bit. Bit with the highest numerical significance.PParameterizationThe setting of parameters for the individual bus stations and their modules in the configuration software of the DP master.PIBAcronym for Proxy Ident Block. This function block represents an ID system in the controller. This provides a standard program interface to the actual application.Bulk readingSimultaneous and unambiguous reading of several RFID data carriers that are led past a read/write head (transceiver).RRepeaterIn digital communication technology, the repeater is a signal regenerator which receives a signal in the bit transmission layer, reconditions it and sends it on. Noise and distortion during the runtime (jitter) and the pulse shape are removed from the received signal during this conditioning process.Reserved areaThis memory area is used for storing passwords for accessing data carriersRDemoSoftware tool for initiating various transponder actions including read/write operations
GlossaryD101831 0713 -  BLident® Installation of the UHF System86RFIDRadio Frequency Identification.RFID technologyThis technology enables a contactless transmission of data by means of an electromagnetic alternating field. This transmission method is also called radio frequency technology. A tag is used as a data carrier.SRead/write headThe read/write head (also read/write device) generates an electromagnetic high frequency field. This is used to transfer data and the power supply for the data carriers (transponder). The data is represented by the modulation of the electromagnetic field.PLCAcronym for programmable logic controller.StationFunctional unit or assembly consisting of several elements.STEP 7STEP 7 is the latest programming software of the Simatic-S7 PLC series from Siemens AG and is the successor to STEP 5.TTagRFID tags (data carriers) are small transponders in a housing suitable for the application, e.g. stickers, chip cards, label.TIDThis memory area contains specific data carrier information that was written beforehand by the manufacturer. TDMAThe Time Division Multiple Access (TDMA) procedure defines specific time slots for the transmission of the responses of different data carriers on a channel. The read/write head defines the number of time slots for the responses of data carriers, for which each data carrier selects a time slot randomly. The read/write head checks the time slots with the respective data carrier responses in succession until the data carrier is detected. If the time slot is exceeded without the corresponding data carrier being detected, the process is repeated until all data carriers in the sensing range are identified. TransceiverCombination of transmitter and receiver.In RFID technology, transceivers are used in the form of so-called “readers” or read/write heads. These devices first send a signal to which a response is sent from the data carrier (e.g. RFID tag), the so-called transponder. This response is then received by the transceiver and forwarded to a (computer) system for further processing.TransponderCombination of Transmitter and Responder Transponder. A transponder consists of a microchip (with a unique identification number), a transmission / receiving aerial and a housing. Data is transmitted between a reader device and the transponder via electromagnetic waves.UUHF - Ultra High FrequencyUHF RFID is implemented in Europe at 865..868 MHz / USA 902..928 MHz / China 840..845 MHz and 920..925 MHz.UIDAbbreviation for “Unique Identifier”. A UID is an unambiguous serial number for a transponder. As an address it indicates the data belonging to the transponder i.e. the tagged product. This data can, for example, be stored in a database.
