D101763 - BL ident® – Start-up with CANopen
D101831 - BL ident® – Installing the UHF system
The manuals listed are available for download from the Internet at http://www.turck.com.
2.2 Compatibility
All technical data refers to the BL ident® system, i.e. the combinations of BL ident® data carriers, read/
write heads and fieldbus modules. Different values may apply to data carriers of other vendors.
2.3 Transmission frequency
The TURCK BL ident® system operates at nationally specified transmission frequencies in the UHF range
(840...960 MHz) between the data carriers and the read/write heads. These national transmission
frequencies for UHF are specified by the relevant national regulation authorities according to the
frequency ranges individually allocated.
UHF systems in this frequency range achieve a longer read/write range than HF systems, of typically
several meters. The operating frequency of devices in the UHF band is, for example, 865...868 MHz in
Europe and 902...928 MHz in the USA. BL ident® read/write heads for the UHF band can only be used in
the specified countries and must not be put into operation outside of these regions. As BL ident® UHF
data carriers are passive devices, they do not radiate any of their own radio waves and are therefore
suitable for worldwide use.
TURCK offers data carrier variants that are specially designed and optimized for specific national
frequency bands in order to achieve as large a communication range as possible.
Alternatively broad-band multi-range data carriers are available for international use.
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/Canada)
840...845 MHz and 920...925 MHz (e.g. for China)
902...907.5 MHz and 915...928 MHz (e.g. for Brazil)
917...920.8 MHz (e.g. for Korea)

These national transmission 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 further information please contact the relevant authorities in the country in which you wish to use
the UHF RFID system.
2.4 Approval of data carriers and read/write heads
The read/write heads mostly require an approval from a national regulation body, depending on the
specific national regulations (in Europe and India, however, no approval is required). A corresponding
approval of the data carriers is not required.
2.5 General information on the UHF data carriers
The UHF data carrier memory hierarchy is divided into four logical areas acc. to ISO 18000-6C (also
called domains) and can take several blocks – each block consisting of 2 bytes.
Domain 0 – reserved area: This bank includes (depending on the data carrier type) the passwords
for accessing the memory and for deactivating the data carrier. The passwords for deactivating are
stored in the memory addresses 00hex to 1Fhex. The passwords for access are stored in the memory
addresses 20hex to 3Fhex. Memory access is normally executed with special protocol commands.
Domain 1 – EPC (electronic product code) or UII (unique item identifier): This bank contains the es-
sential 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
information (protocol control byte, from address 10hex). The actual data range of the UIIs starts at
address 20hex. The data carriers are identified within the BL ident® system via the first eight bytes of
the data range, i.e. from address 04hex to 0Chex.
Domain 2 – TID (tag identification): This bank contains one of three values for identifying the class
code (E0hex, E2hex or E3hex) in accordance with ISO/IEC 15963, contained in the memory addresses
00hex to 07hex. If the class ID is E0hex, the TID contains a 48-bit serial number.
The composite 64-bit data carrier ID is assigned once within all data carrier classes that are defined
in ISO/IEC 15963 and are write protected by the manufacturer. If the class ID is E2hex, the TID contains
a 12-bit data mask ID 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
user memory for different data lengths, the 48-bit serial number, the 1-bit XTID and the 15-bit XTID
header data. The composite 80-bit data carrier ID is assigned once within all data carrier classes that
are defined in ISO/IEC 15963 and are write protected by the manufacturer.
Domain 3 – User area: This bank is optional and contains a memory area of varying size for use as
required by the user.
Attention
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.

D101925 0412 - BLident® UHF 2-3
General information on the UHF data carriers
BL ident® UHF data carriers with the following memory types are currently available:
EEPROM-U-Code G2
EEPROM-Monza
EEPROM-Higgs
2.5.1 Multiple access (multi-tag detection, bulk reading)
With UHF-RFID the data carriers in the BL ident® system are identified by the first eight bytes of the UII,
i.e. from address 04hex to 0Chex. These must be different for multiple access! (multiple access means that
a read/write head can communicate with different data carriers simultaneously. The read/write head
can therefore specifically address a data carrier by means of its UII)
If the data carriers are all factory set with the same UII, these must be written individually with different
UIIs before being used for the first time in applications with multiple access.

memory hierarchy
Note
The number of banks for the different memory types varies in part.
For example the Impinj Monza 3 only has three banks (the user bank is missing here), while
the Alien Higgs 3 has all four banks.

General information on the UHF read/write heads
2.5.3 Read range/write range
The achievable read/write distances depend on the relevant combination of data carrier and read/write
head. 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 normally
have a read/write range of several meters.
2.6 General information on the UHF read/write heads
The operating frequency in the UHF band is between 840 MHz and 960 MHz depending on the region
of use.
All TURCK UHF read/write heads are suitable for single and multiple access of the data carriers.
2.6.1 Connecting the read/write heads
Note
Only read/write heads with a type label on the back (as in Figures 2 and 3) can be used on the
devices with the TURCK BL20, BL67 and BLcompact systems.
Refer to the enclosed instruction leaflets of the devices for further information on the
connection.

Note
The maximum read/write distance of several meters is only an idealized value under
laboratory conditions.
Component tolerances, mounting location in the application, ambient conditions and the
effect of materials (particularly metal and liquids) can reduce the achievable distances.
The parameters for achievable traversing speed (read and write operations on the fly) and
the maximum transmittable data volume also vary, depending on the actual transmission
curve 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.
For this reason, the application must be tested under real conditions!

Attention
Possible device damage with BL20!
The power supply of the read/write heads must not be connected via the BL20 base modules,
since the current via the RFID I/O modules is not sufficient. Whilst the wiring of the data
cables is routed via the base modules, the power supply must be fed directly via the supply
lines of the cables .../S2500, .../S2501 and .../S2503!

2.6.2 LED functions of the read/write heads
Refer to the enclosed instruction leaflets of the devices for the LED function of the read/write heads.
Note
The functions of the LEDs can be assigned as required and differently to the standard
configurations described in the enclosed instruction leaflets. For this use the RDemo and
WebConfig software tools in conjunction with the STW-RS485-USB interface converter
(Ident no. 7030354).
