5 Function
5.1 ID tags
The ID tags are passively operated without a battery. The energy required for operation is provided by
the read/write head.
The energy is provided via an inductive coupling. The integrated antenna coil in the read/write head
generates a magnetic field which partly penetrates the antenna coil of the ID tag. A voltage is
generated by induction that supplies the data carrier with energy.
The device supports ID tags according to ISO 15693.

6 Installation
6.1 Notes on the unit installation
When mounting several RFID units adhere to the minimum distances between the systems.
Flush mounting of a read/write head in metal reduces the read/write distance.
Device performance can be affected if positioned in the immediate vicinity of powerful HF
emission sources such as welding transformers or converters.
6.2 Avoiding interference
The device generates a modulated electrical field with a frequency of 13.56 MHz.
Avoid interference with data communication:
uDo not operate any devices in the vicinity that use the same frequency band.
wSuch devices are for example frequency converters and switched-mode power supplies.
If there are other devices in the same frequency band in the vicinity:
uThe mounting distances between the devices should be as large as possible.
uUse the devices in alternating operation.
uSwitch the HF field of the device on/off.

9 Parameter setting
The parameters of the device are set using a software via IO-Link (for example ifm moneo configure
SA).
More information can be found in the IODD of the unit: www.ifm.com
9.1 Parameter
9.1.1 Data block size
The memory area of an ID tag is organised in data blocks. The parameter specifies the size of a data
block. The set value must correspond with the value of the ID tag indicated in the data sheet.
The following values are permissible:
4,8,16 and 32 bytes per block.
The data block size is only required for the internal data processing in the device. The user can
access the process data images byte by byte on the memory area of the ID tag.
9.1.2 Data alignment
The parameter sets the order of the data in a data block of the ID tag.
Example
For an ID tag with block size 4 bytes the data can be ordered as in the tables:
Data block 0 Data block 1
Byte 3 Byte 2 Byte 1 Byte 0 Byte 3 ...
Tab.1: Normal order
Data block 0 Data block 1
Byte 0 Byte 1 Byte 2 Byte 3 Byte 0 ...
Tab.2: Reversed order
9.1.3 Data hold time
The data hold time indicates the time during which the data of the process data input image can be
held constant. Depending on the operating mode, this concerns
• the UID,
• the "Tag present" bit,
• the data in Auto read and Auto write mode.
The parameter “Data hold time” does not influence data transfer in the operating modes "Read data"
and "Write data".
Example
When the data hold time is set to 500 ms, the UID and the "Tag present" bit are transferred for min.
500 ms via IO-Link.
This also applies if the ID tag is no longer within the range of the device.

DTI600
16
9.1.4 Address for automatic read/write
The parameter "Address for automatic read/write" sets the start address of the memory area that is
accessed in the operating modes "Auto read" and "Auto write".
The address is provided in bytes.
In the operating modes “Auto read" and "Auto write" the device reads and writes a specified number of
data of the ID tag automatically.
The addressed memory area must be within the available memory area of the ID tag:
Auto Read and Write Address +
Auto Read and Write Data Length ≤
Number of available bytes on the ID tag
The number of available bytes is indicated in the data sheet of the ID tag.
9.1.5 Data length for automatic read/write
The parameter "Data length for automatic read/write" sets the length of the memory area that is read
and written.
The length is indicated in bytes. The minimum length is 1 byte and the maximum length is 29 bytes.
In the operating modes “Auto read" and "Auto write" the device reads and writes a specified number of
data of the ID tag automatically.
The addressed memory area must be within the available memory area of the ID tag:
Auto Read and Write Address +
Auto Read and Write Data Length ≤
Number of available bytes on the ID tag
The number of available bytes is indicated in the data sheet of the ID tag.

10 Operation
The device supports several operation modes selected with the command value in the process data
output image:
Operating mode Command value Description
Read UID 0x00 Operating mode Read UID (Ò/18)
Auto read data 0x01 Operating mode Auto read data
(Ò/19)
Auto write data 0x02 Operating mode Auto write data
(Ò/20)
Read data 0x03 Operating mode Read data (Ò/21)
Write data 0x04 Operating mode Write data (Ò/25)
For all operating modes, the same status bits and error values in the process images apply.
10.1 Deactivate internal antenna
The internal antenna of the unit can be deactivated at any time. With antenna deactivated
• the device can still be accessed via IO-Link,
• no high-frequency magnetic field is generated by the unit,
• the unit does not recognise ID tags.
Interference between units mounted next to each other is reduced by deactivating the antenna.
Deactivate the internal antenna:
uSet the "Cmd Antenna deactivate" bit in the process data output.
The status of the internal antenna is queried via the bit “Antenna deactivated“ in the process
data input image.
10.2 Operating mode Read UID
In the operating mode "Read UID" the UID of an ID tag is read. Then the UID is available in the
process data input. If no ID tag is in the range of the device, the 8 bytes of the UID get the value
"0x00".
As soon as an ID tag is detected by the device, the UID is transferred. The transfer is continued for the
min. length of the data hold time. If a new ID tag appears in the detection range during the data hold
time, the UID of the new ID tag is transferred.
The default operating mode after the unit is started is "Read UID".

30 ignored 0x00
31 ignored Error value
10.3 Operating mode Auto read data
In the operating mode "Auto read data" the bytes 0 to 28 represent the data in the memory area of the
ID tag. The memory area is set by the parameters "Address for Auto Read/Write" and "Data Length for
Auto-Read/Write".
For memory areas with a data length of < 29 bytes the data remaining in the process image is filled
with the value 0x00.
The data in the process image is updated as soon as an ID tag enters the detection range. The data in
the process image is valid as soon as the status bit "Cmd End" is set.
If the ID tag leaves the detection range, the data is held in the process image according to the data
hold time. If the data hold time is exceeded and there is no ID tag in the detection range, the data is
filled with the value 0x00.
If the ID tag remains in the detection range, the data can be read with the status bit "Cmd Start". If
reading was unsuccessful, the error value is shown in the process image.
The smaller the "Length for Auto Read/Write" is set, the less time is needed for reading. That
means that the dwell time of the ID tag in the detection range can be shorter.

10.4 Operating mode Auto write data
In the operating mode "Auto-write data" the data to be written is defined by the process data output
image. The data is set with the parameters "Address for Auto Read/Write" and "Data Length for Auto
Read/Write".
The data is written with the address and length to an ID tag as soon as the ID tag enters the detection
range.
Max. 29 bytes become defined in the process data output image (bytes 0 to 28). For memory areas
with a data length of < 29 bytes the remaining data is ignored and not written to the ID tag.
If writing was successful, the written data is copied to the process data input image and the status bit
"Cmd End" is set.
If the ID tag leaves the detection range, the data is held in the process image according to the data
hold time. If the data hold time is exceeded and there is no ID tag in the detection range, the data is
filled with the value 0x00.
