HF Bus Mode – Overview
6Hans Turck GmbH & Co. KG | T [phone] | F [phone] | [email protected] | www.turck.com
2 HF Bus Mode – Overview
In HF bus mode, up to 32 bus-compatible read/write heads per RFID channel can be connected
to the TBEN module. Depending on the number of read/write heads connected and the power
consumption of the connected heads, an additional power supply may be required. In order to
determine whether an additional power supply is required, a power consumption analysis of
the connected read/write heads must be performed. A tool to help calculate the power con-
sumption of the read/write heads is available at www.turck.com/hf-busmodus.
Every connected read/write head supplies a "tag present" signal in HF bus mode. By default, a
command can only be processed by one read/write head, making HF bus mode suitable for
static applications and slow dynamic applications.
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.

HF bus mode supports the HF read/write heads from firmware version Vx.90. Continuous HF
bus mode supports the HF read/write heads from firmware version Vx.93. On the TBEN-
S2-2RFID-4DXP module, continuous HF bus mode requires firmware version V3.6.1.0 or later.

4HF Applications – Setting HF Bus Mode
HF bus mode supports the HF read/write heads from firmware version Vx.90. Continuous HF
bus mode supports the HF read/write heads from firmware version Vx.93. The read/write heads
can be addressed as follows:
nAutomatic addressing
nManual addressing via the command Set read/write head address
nManual addressing via the Turck Service Tool
The addresses must be assigned per channel from 1 to 32.
Automatic addressing of read/write heads
NOTE
Turck recommends making the bus address of the read/write head visible on the
device.
Read/write heads with the default bus address 68 can be addressed automatically. For this to
happen, the corresponding XCVR bit must be set in the parameter data.
Switch on the RFID interface power supply.
Activate the required read/write heads in the parameter data via the appropriate XCVR
bit.
Connect the read/write heads to the interface one after the other in a line.
aAddresses are allocated in ascending order to the read/write heads in the order in which
the heads were connected. The lowest address is automatically assigned to the next
read/write head with the default address 68 that is connected.
aThe addressing is successful if the LED of the read/write head is permanently lit.
Manually addressing read/write heads — Setting the HF read/write head address command
NOTE
Turck recommends making the bus address of the read/write head visible on the
device.
Information on addressing the read/write heads via the RFID interface with the Set HF read/
write head address command is provided in the operating instructions. With manual address-
ing via the Set HF read/write head address command, the read/write heads must not be activ-
ated until the addressing is completed.
Activate the required read/write heads in the parameter data via the appropriate XCVR
bit.
Manually addressing read/write heads using the Turck Service Tool
NOTE
Turck recommends making the bus address of the read/write head visible on the
device.
The following accessories are required to address the read/write heads in HF bus mode using
the Turck Service Tool. Accessories are not supplied with the device and must be ordered sep-
arately.

5 Operation
5.1 Executing commands in HF bus mode
Set the parameter data.
Select the HF Bus Mode operating mode.
Activate the connected read/write heads.
Set the input data.
Specify the command code.
Set the start address for the command.
Set the required read/write head address.
Send the command to the read/write head.
5.2 HF applications — Using continuous HF bus mode
In Continuous mode (HF), the read/write head can read or write up to 64bytes (see table "User
data areas for the HF tag").
The following parameters must be set in Continuous mode:
nTag type
nCommand in Continuous mode
nLength in Continuous mode
nStart address for the command in Continuous mode
nOptional: Start address in the process output data for activating the grouping
For Read or Write commands: Enter the tag type. Automatic detection is not possible.
Select the command in Continuous mode (CCM): Inventory, read, tag info and write are
possible.
Enter the length in Continuous mode (LCM): Enter the length of the data to be read in
bytes. The start address must be a multiple of the block size of the tag used.
Enter the start address for the command in Continuous mode (ACM). The start address
must be a multiple of the block size of the tag used. The block size of the tags can be
found in the table below. Odd bytes cannot be addressed.
Optional: Set the grouping via the Start address parameter in the process output data:
Set the value for the Start address parameter to 1. If the grouping is activated and there
is still a UID saved in the FIFO memory of the module, a UID is no longer saved as a new
reading after it is first read. For subsequent readings, only the address of the read/write
head that was last read by the tag and the number of readings are updated.
For a Write command, enter the data to be written in the write data area.
Execute the Continuous mode command.
aThe set command is preloaded and executed for all active read/write heads as soon as a
tag is in the field.
When executing the Read command and retrieving UIDs, the data received from the
read/write head is retrieved cyclically and stored in the FIFO memory of the interface as
follows:
Type Name Meaning
uint8_t data[8] uint8_t UID [8]
uint8_t Reserved
uint8_t Address Read/write head address
uint16_t Number of readings (only if grouping is activated)
Execute the Idle (0x0000) command. The Idle command does not end Continuous mode.

Operation
14 Hans Turck GmbH & Co. KG | T [phone] | F [phone] | [email protected] | www.turck.com
To transfer data from the FIFO memory of the interface to the controller, execute the
Read data from the buffer (0x0011) command. In addition to the read data, the address
of the read/write head that is being used is also transferred. The length of the data avail-
able in the FIFO memory is displayed in the input data under Data (bytes) available
(BYFI). The length of the data must be consistent. Example: If the UID, reserved byte and
read/write head address for each tag are being written to the FIFO memory, at least
10bytes of data must be read from the buffer.
NOTE
Data in the FIFO memory is not overwritten until it has been transferred to the con-
troller. New readings are stored in the FIFO memory.
To end Continuous mode, execute the End Continuous mode (0x0012) command.
or
To end Continuous mode and clear the FIFO memory of the interface, send the Reset
(0x0800) command.
NOTE
The data must be transferred from the device to the higher level on a regular basis. If
the 16-KB ring buffer is full, no further data can be saved and the device displays an
error message.

5.3 Replacing bus-capable read/write heads
Remove the faulty read/write head.
Connect the new read/write head with the default address 68 (delivered with …/C53).
If multiple read/write heads are being replaced: Replace the read/write heads in the or-
der in which they were connected.
aAddresses are allocated in ascending order to the read/write heads in the order in which
the heads were connected. The lowest address is automatically assigned to the next
read/write head with the default address 68 that is connected.
aIf the LED on the read/write head is permanently lit, this indicates that the addressing is
complete.
5.4 Typical times for processing a command (HF bus mode)
The time required to cyclically process the command depends on how long the tag is in the de-
tection range of the read/write head (bypass time). The bypass time is set at 48 ms by default.
The bypass time can be set by the user. If the bypass time is set differently, the difference from
the time taken to process a command must be added or deducted.
The time taken for all read/write heads to be addressed once by the interface is calculated as
follows:
Number of read/write heads × bypass time
This time corresponds to the update rate for the Tag in detection range bit and must also be
taken into account when calculating the total time taken to process a command.
The inventory command must be executed separately for all read/write heads.
Command System cycle time Time required Dependence on factors such as
protocol, system, etc.

the individual read/write
heads are accessed varies.

Operation

5.5 Continuous HF bus mode — Data retrieval
All activated read/write heads are triggered within a time frame of bypass time + 10ms. Within
this time frame, the set command (e.g. inventory, read, write) is processed in Continuous mode.
While a command is being executed by all activated read/write heads, only one read/write
head sends data to the RFID interface. The other read/write heads store the read data for sub-
sequent retrieval. When a new tag is detected by the same read/write head, any data in the buf-
fer of the read/write head that has not yet been transferred to the RFID interface is overwritten.
During the time between two requests and when sending data to the RFID interface, the read/
write heads do not recognize any tags. The required waiting times are given in the following
table:
Command Waiting time
Inventory 15ms
Read 25ms
Write 35ms
By default, the bypass time in HF bus mode is 48ms.
The following table shows when commands are executed (CMD) and data is exchanged (DATA).
nCMD: Command is being executed.
nDATA: Data is being exchanged.
nDATA or CMD: If data is stored on the read/write head, the data is sent to the TBEN module. If
no data is stored on the read/write head, the command is executed.
