4.3 Operating principle
The interfaces are equipped with a fieldbus interface for EtherCAT. The interface is linked to an
(existing) fieldbus system as an EtherCAT device. The interfaces are provided with a fieldbus
interface and fieldbus-independent I/O electronics with an RFID interface. During operation,
the process data is exchanged between the fieldbus and RFID system. The read/write devices
are connected to the interfaces via the RFID interfaces. The interface signals of indicators,
sensors and actuators can also be processed via eight universal digital channels.
4.4 Functions and operating modes
The compact RFID interfaces transfer the data between the RFID level (read/write device and
tag) and the controller level. HF read/write heads and UHF readers can be connected to the
RFID channels. Parallel operation of HF read/write heads and UHF readers on the same device is
also possible.
The device enables the execution of different commands such as Inventory (single-tag and
multitag applications), read, write and password protection. Additional functions are provided
for optimizing the speed, the self triggering of the system, as well as for backup and restore
operations. In every write or read cycle, up to 128 bytes can be transferred on each channel to
the controller. The data must be fragmented in order to transfer more than 128 bytes.
Sensors and actuators can be connected to the universal digital channels. In all, up to eight 3-
wire PNP sensors or eight PNP DC actuators can be connected per input or output. The max-
imum output current per channel is 2 A.

The device supports the following EtherCAT communication profiles:
nCoE (CAN Application Protocol over EtherCAT): The object dictionary is provided via the CoE
interface. The object dictionary contains all device-specific parameters.
nEoE (Ethernet over EtherCAT): The standard Ethernet protocol is tunneled via the EoE com-
munication protocol. An IP address for EoE can be assigned to the device so that the device
can be configured via the web server or via DTM.
nFoE (File Access over EtherCAT): The firmware update is carried out via the FoE communica-
tion protocol.
4.4.3 Data transfer to the PLC
In every write or read cycle, up to 128 bytes can be transferred on each channel. The data must
be fragmented in order to transfer more than 128 bytes. The amount of write or read data
transferred per cycle can be set as follows for EtherCAT:
n8 bytes
n16 bytes (default setting)
n32 bytes
n64 bytes
n128 bytes
4.4.4 RFID channels – operating modes
Five different data interfaces can be selected for the RFID channels:
nHF compact
nHF extended
nHF bus mode
nUHF compact
nUHF extended
Different functions are available to the user, depending on the selected data interface.
HF compact mode
HF compact mode is suitable for transferring smaller data volumes of up to 128bytes (e.g. UID)
in single-tag applications.

Product description
Functions and operating modes
14 Hans Turck GmbH & Co. KG | T [phone] | F [phone] | [email protected] | www.turck.com
HF extended mode
HF extended mode contains all the functions provided in HF compact mode. It is also possible
with fragmentation to transfer more than the set data size per write or read cycle (example: 128
bytes). The operating mode is suitable for single-tag and multitag applications.
NOTE
Not all commands are supported in multitag mode.
The user can set a command timeout to define the time for the execution of a command.
HF extended mode enables the use of Continuous mode for the repeated execution of an In-
ventory, Tag info, Read or Write command. In Continuous mode the read/write head executes
the commands autonomously. Different data is stored in the internal memory of the interface.
The memory operates as a FIFO memory.
HF bus mode
In HF bus mode up to 32 bus-capable read/write heads per RFID channel can be connected to
the RFID module. An additional power supply may be required depending on the number and
power consumption of connected read/write heads. A power consumption analysis of the
connected read/write heads is required in order to determine the additional power supply
required. A tool is provided at www.turck.com/hf-busmodus for calculating the power.
Every connected read/write head supplies a “ Tag present” signal in HF bus mode. HF bus
mode is suitable for static applications and very slow dynamic applications because a com-
mand can only be processed by one read/write head at a time.
In Continuous HF bus mode, a command is performed simultaneously at all read/write heads in
a bus topology. The logged data is stored in the ring memory of the module.

Continuous bus mode supports HF read/write heads from firmware version Vx.93.
UHF compact mode
UHF compact mode enables up to 128 bytes of data to be transferred in single-tag applications
(e.g. EPC).
UHF extended mode
All functions of the UHF compact mode are included in UHF extended mode. It is also possible
to transfer more than 128 bytes of data. The operation mode is suitable for single-tag and mul-
titag applications. The user can set a command timeout to define the time for the execution of
a command.
UHF extended mode enables the use of Presence sensing mode for the repeated execution of
an Inventory, read or write command. In Presence sensing mode the UHF readers are automat-
ically switched on or off and also carry out the commands automatically. In this case, the read
data is stored in the internal memory of the interface. The memory operates as a FIFO memory.

4.4.6 Loop counter function
The loop counter function is provided for rapid command processing. The loop counter func-
tion only requires two PLC cycles to execute a command repeatedly (flow chart see [}253]).
This increments the loop counter to execute a command repeatedly. At least four PLC cycles
are required in conventional command processing. In order to execute a command repeatedly
with conventional command processing, a command has to be reset and then set again. The
loop counter function is provided for special commands. If the command was successfully ex-
ecuted, the command code is output in the response data.
4.4.7 Universal digital channels – functions
The device is provided with eight universal digital channels, which can be used as inputs or
outputs according to the application requirements. In all, up to eight 3-wire PNP sensors or
eight PNP DC actuators can be connected per input or output. The maximum output current
per channel is 2A.

Fig.6: Grounding clip (1), grounding ring (2) and metal screw (3)
The grounding ring (2) is the module grounding. The shielding of the I/O level is permanently
connected to the module grounding. The module grounding is only connected to the refer-
ence potential of the installation when the module is mounted.
I/O level shielding
In the case of direct mounting on a mounting plate, the module grounding is connected to the
reference potential of the system via the metal screw in the lower mounting hole (3). If module
grounding is not desired, the electrical connection to the reference potential must be interrup-
ted, e.g. by using a plastic screw.
