The TURCK BL ident® UHF System
D101831 0713 - BLident® Installation of the UHF System14
2.1 BL ident® – Modular RFID system
BL 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 concept
The 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 conditions
2.1.4 BL ident® interfaces
The 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 compact
Gateways (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.

BL ident® – Modular RFID system
Interface modules: electronic and base modules
The individual interface modules of the modular I/O systems each consist of a passive base module and
an electronic module.
The base modules consist of the connection technology for connecting the field devices such as read/
write heads, sensors and actuators. 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)

D101831 0713 - BLident® Installation of the UHF System16
The 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.

2.2.1 Networking with BL ident® UHF systems
BL 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® system
In 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 protection
Some 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 23
Features and application areas of the BL ident® system
2.4.2 Lifespan
The 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 frequency
The 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.pdf
For more detailed information please contact the relevant authorities of the country where you wish to
use the UHF RFID system.

2.4.4 Mounting types
Data carriers
Data 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 heads
Different 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 Memory
EEPROM 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 head
The 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.

User data areas of the UHF data carrier variants
2.6 User data areas of the UHF data carrier variants
2.7 General information on the UHF data carriers
The 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.
Caution
Possible 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.

BL ident® UHF data carriers are currently available with the following memory types:
EEPROM-U-Code G2
EEPROM-Monza
EEPROM-Higgs
Note
The number of areas for the different memory types currently varies.
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.

Speed of the data carrier at the read/write head on RFID systems
2.8 Speed of the data carrier at the read/write head on RFID systems
The 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 range
The 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.
Note
The 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!

2.10 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-
ment
All 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.

D101831 0713- BLident® Installation of the UHF System40
3.1 Selection criteria for data carriers, read/write heads and interface module
In 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 distance
UHF 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 zone
As 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 41
Transmission zone and read/write distance
Reserve 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
distances
Dread_ideal
Dread_real_max
Dwrite_max
ca. 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.
Note
Appropriate range tests in real conditions must be carried out in all cases!
3.2.2 Minimum distance of data carrier to the read/write head
With 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 carriers
The 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..
Note
The 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 – Planning
D101831 0713- BLident® Installation of the UHF System42
3.2.4 Reading and writing in static mode
In 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.
Note
Reading 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 rate
The 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 writing
The 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).
Note
TURCK 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 mode
In dynamic mode (on the fly) the minimum distance of successive data carriers depends on the data
volume and the bus cycle time.
Note
Appropriate tests to determine the minimum distance of successive data carriers must be
carried out before startup.
D101831 0713- BLident® Installation of the UHF System 43
Transmission zone and read/write distance
3.2.9 Minimum distance between two adjacent data carriers in multiple access
Multiple 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.
Note
Information 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.
Note
The number of automatic retries can be set via the offline parameters of the higher-level
controller (PLC).

4.1.1 Minimum / maximum distance between read/write heads
The 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.

4.1.2 Minimum distance of read/write heads to conductive materials
A 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.

Note
The 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.

4.1.6 Interaction when using several read/write heads
If several RFID read/write heads are in operation, there is a danger that RFID data carriers are also read
by other read/write heads. 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 agility
In 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 procedure
With 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 guidelines
D101831 0713 - BLident® Installation of the UHF System50
Other 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.

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.
Note
When 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 51
Effect 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:

For applications in Europe, the read/write heads should be assigned to and use equally the

Effect 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 distance
The 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 carriers
The 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.
Note
Appropriate range tests in real conditions must be carried out in all cases!

4.1.9 Data carrier orientation in the room
The 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
alignment
If 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.

Behavior of electromagnetic waves in the UHF range
4.2 Behavior of electromagnetic waves in the UHF range
4.2.1 Effect of reflections and interference
Reflections and interference
Electromagnetic 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.
Note
Appropriate range tests in real conditions must be carried out in all cases!
Reducing the effect of reflections/interference on data carrier detection
Reduce 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 substances
Non-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 components
The 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 interference
Electromagnetic 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 guidelines
D101831 0713 - BLident® Installation of the UHF System56
Third party components in the same frequency band
Third 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.

6.1 Target group
These 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,

6.2 Propagation of electromagnetic interference
Electromagnetic 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

source of interference
e.g. motor
susceptible equipment
e.g. read/write head
link
e.g. cable connector
The 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 63
RFID interference
6.3 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 paths
There 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 – Definition
The 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 Guidelines
D101831 0713 - BLident® Installation of the UHF System64
As 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 EMC
Observe 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 65
Basic rules for ensuring EMC
6.5.1 Installation in a control cabinet
Magnetic 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 sources
Prevent 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 bonding
Potential 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 Guidelines
D101831 0713 - BLident® Installation of the UHF System66
6.5.4 Shielding the cables
Signal 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 band
D101830 0713 - BLident® Installation of the UHF System68
7.1 Function
The 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:

data carrier
UB
modulator
demodulator
control logicsmemory
7.1.1 Memory module
The 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 °C
Electrical 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 antenna
UHF 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.

Type overview of the data carriers
7.2 Type overview of the data carriers
The 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.

BL ident® read/write heads for the UHF band
D101831 0713 - BLident® Installation of the UHF System74
8.1 Function
The 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).
Note
For 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 head
Modulator
Demodulator
Generator
8.1.1 Read/write head antenna
The 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.

8.3 Connecting the read/write heads
The read/write heads are connected with the BL ident® RFID electronic module via M12 × 1 male
connectors. The power supply (24 VDC) and function are implemented with the BL ident® RFID
electronic module.
Caution
Possible device damage with BL20 due to incorrect connection of the power supply to the BL
ident® RFID electronic module
The power supply of the read/write heads must not be connected via the BL20 base modules
because the current via the RFID I/O modules is not sufficient.
While the wiring of the data cables is implemented via the base modules, the power supply
must be implemented directly via the .../S2500, .../S2501 and .../S2503 supply cables!
Note
Only read/write heads with a sticker on the back (as shown in figures 22 to 24) can be used
on the devices with the TURCK systems BL20, BL67 and BLcompact).
Refer to the enclosed packing slips for further information on connecting.

CC
CPU
Acronym for “Central Processing Unit”. Central unit for data processing, the core of a computer.
D
dBm
The 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)
Distribution
Distribution comprises all activities related to the transfer of goods between economic entities.
DIN
German acronym for German Industrial Standard.
DP master class 1
The 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 2
Exclusive transmission of acyclical demand data. This data transmission can be carried out, for example, using an engineering
tool (PC application program).
DPV1
Functional 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.
E

EEPROM 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.
Glossary
D101831 0713 - BLident® Installation of the UHF System84
EMC
Electromagnetic 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.
EPC
The 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.
Ground
In 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”.
Grounding
The connection of an electrically conductive component to the ground using a grounding device.
Grounding device
One or several components that have direct and good contact with the ground.
ERP/EIRP
The 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).
F
Fieldbus
Data 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 hopping
This 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.
G
GSD - 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.

This 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.
S
Read/write head
The 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.

T
Tag
RFID tags (data carriers) are small transponders in a housing suitable for the application, e.g. stickers, chip cards, label.
TID
This memory area contains specific data carrier information that was written beforehand by the manufacturer.
TDMA
The 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.
Transceiver
Combination 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.
Transponder
Combination 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.
