4.3 Operating principle
The read/write heads are used for contactless data exchange with tags. For this the controller
sends commands and data via the interface to the read/write head and receives the corres-
ponding response data from the read/write head. The reading of the IDs of all RFID tags in the
read area or the writing of an RFID tag with a specific production date are examples of typical
commands. To communicate with the tag, the data of the read/write head is coded and trans-
ferred via an electromagnetic field, which at the same time supplies the tags with power.
A read/write head contains a transmitter and a receiver, an interface to the interface and a
coupling element (coil and dipole antenna) for communicating with the tag. Electromagnetic
wave propagation is used for the transmission between read/write head and tag on devices for
the UHF range.
IC
Read/write head Data carrier
UHF: electromagnetic wave
Fig.3: Operating principle of UHF-RFID
The antenna of the read/write head generates electromagnetic waves. This produces a trans-
mission window as a so-called air interface in which the data exchange with the tag takes place.
The size of the transmission window depends on the combination of read/write heads and
tags, as well as on the relevant environmental conditions.
Each read/write head can communicate with a number of tags. This requires the read/write
head and the tag to operate in the same frequency range. Depending on the power and fre-
quency used, the device ranges vary from a few millimeters up to several meters. The specified
maximum read/write distances only represent typical values under laboratory conditions
without allowing for the effect of materials. The achievable distances may vary due to compon-
ent tolerances, the mounting situation in the application, ambient conditions and the effect of
materials (particularly metal and liquids).

Product Description

4.4 Functions and operating modes
The devices operate with an integrated or external antenna (TN-UHF-Q300…) or only with an
external antenna (TN-UHF-Q180L300…). The devices enable passive UHF tags to be read or
written in single and multi-tag operation. For this the devices form a transmission zone that
varies in size and range according to the tags used and the operating conditions of the applica-
tion. Refer to the data sheets for the applicable maximum read/write distances. The devices can
be fully tested, configured and parameterized from a PC using the specified software tools.
The Linux operating system enables the device functions to be programmed with C, C++,
NodeJS or Python. It is also possible to integrate middleware functions on the device.
Sensors and actuators can be connected to the configurable digital channels. Up to four 3-wire
PNP sensors or two PNP DC actuators with a maximum output current of 2 A per output can be
connected. An external power supply is required in order to use the digital channels as outputs.
4.5 Technical Accessories
Accessories for mounting, connecting and parameterizing can be found in product database or
the Accessories List for TBEN (D301367) under www.turck.com. The accessories are not part of
the scope of delivery.

7 Commissioning
The Linux operating system enables the device functions to be programmed with C, C++,
NodeJS or Python.
Additional software tools (e.g. PuTTY) are required to access the device via the console. A file
exchange between the device and a PC can be used, e.g. via WinSCP. The following login data
is stored on the device by default:
User: user
Password: password
NOTE
The read/write head protocol is not implemented by default. The protocol must be
implemented by the user.
7.1 Setting read/write head parameters with the DTM
The UHF settings of the device can be assigned additional parameters via a DTM.
All the required Turck software components can be downloaded via the Turck Software Man-
ager. The Turck Software Manager is available free of charge from www.turck.com.
NOTE
The parameterization function is only available in English. All parameters are written
in the DTM.
The individual read/write heads are available in different variants. When a connection is made
to a connected read/write head, the DTM automatically detects the relevant device and deac-
tivates menu items that are not supported. The connection cannot be established if a different
variant than set in the project tree is connected.
NOTE
Adjustable parameters are indicated in the DTM with a green arrow. Fixed paramet-
ers are indicated by gray arrows.
