DTI801 DTI901 DTI911 DTI961 3 Intended use The device is an RFID read/write head for reading and writing ID tags in industrial environments. The read/write head is configured and data is exchanged via the integrated IO-Link interface. Possible applications: • Material flow control in production lines • Warehouse management by the automatic detection of stored products • Tank management, order picking or product tracking.
DTI801 DTI901 DTI911 DTI961 4 Items supplied • Compact DTI RFID device • Package insert 'general information’ • Package insert 'radio approval' The device is supplied without installation and connection accessories. Available accessories: www.ifm.com. The optimum function is not ensured when using components from other manufacturers.
DTI801 DTI901 DTI911 DTI961 5 Function The ID tags are operated passively without battery. The energy required for operation is provided by the compact RFID device. The energy is transferred via an electromagnetic wave. The receiving antenna takes up the wave and transforms it into voltage which supplies the data carrier with energy. GB The radiated power is specified in ERP (Effective Radiated Power) and in EIRP (Effective Isotropic Radiated Power) for the devices.
DTI801 DTI901 DTI911 DTI961 DTI961 Article number: DTI961 Function: compact RFID device Type designation: DTRUHFA HLRWPNUS04 Type: rectangular Operating frequency: 916.8 – 920.4 MHz Typical transmitter power: 25.2 dBm EIRP (331 mW) 5.2 IO-Link 5.2.1 General information This device has an IO-Link interface which enables direct access to process and diagnostic data. It is also possible to set the parameters of the device while it is in operation.
DTI801 DTI901 DTI911 DTI961 The parameter does not affect data transmission in the following operating modes: - "EPC LIST (Ò Operating mode "EPC LIST / 30)" - "WRITE EPC (Ò Operating mode "WRITE EPC” / 32)" - "READ DATA (Ò Operating mode "READ DATA / 35)" - "WRITE DATA (Ò Operating mode "WRITE DATA” / 38)" GB - "LOCK DATA (Ò Operating mode "LOCK DATA” / 40)" 5.2.3.
DTI801 DTI901 DTI911 DTI961 5.2.3.5 Parameter “ID Tag Access Password" (Index 1906, subindex 0) The ID tags can be provided with read/write-protection. Then a password is required for access. The parameter stores the password in the device. The password is used for all read and write access to the ID tags. The password is 4 bytes long. If all 4 bytes have the value "0x00", no password is used to access the ID tags. The password is used for all ID tags. Individual passwords per ID tag are not possible. 5.
DTI801 DTI901 DTI911 DTI961 5.2.3.10 Parameter "RSSI Filter Lowest Value” (Index 1914, subindex 1) The RSSI filter spatially classifies ID tags based on their received signal (RSSI). A typical application is the limitation of the spatial detection area. The parameter sets the lowest value for the RSSI filter. All ID tags with a reception signal below the set value are filtered out. GB 5.2.3.
DTI801 DTI901 DTI911 DTI961 Detection mode Typical number of ID tags in the field at the same time Moving ID tags <4 This mode is particularly suitable for an ID tag that moves quickly through the detection field of the device. The "coming/going messages" can be output with a delay. Multiple ID tags 4-16 This mode is particularly suitable if there are several ID tags in the detection field at the same time.
DTI801 DTI901 DTI911 DTI961 The position of the data is specified by the parameters "Selection start bit" and "Selection length” in each case. If the data matches the comparison bit mask, the ID tag is selected and further processed by the device. Examples Only ID tags with a certain EPC value are detected in the selection. This makes it possible to distinguish between ID tags on a transport pallet and ID tags directly on the goods on the transport pallet.
DTI801 DTI901 DTI911 DTI961 Memory bank Description USER The memory bank USER can be freely used for the user's data. RESERVED The memory bank RESERVED contains configuration data of the ID tag and cannot be used by the user. The memory banks have different sizes depending on the type of ID tag, so the maximum data length that can be used varies. Further information can be found in the data sheets of the ID tags.
DTI801 DTI901 DTI911 DTI961 6 Mounting ATTENTION Radiated electromagnetic field strengths w The device sends ultrahigh frequency electromagnetic waves. It complies with the country-specific limit values for the public and workers. GB u Disconnect the device in the vicinity of medical equipment. 6.1 Installation instructions for devices Devices installed next to each other interfere if they are not configured correspondingly.
DTI801 DTI901 DTI911 DTI961 The UHF field is attenuated if there are people or objects (cables, metal profiles, etc.) between the device and ID tag. u Keep the area between the device and ID tag clear during reading or writing. 6.4 Mechanical design 1 2 1 Sensing face 2 Connections (can be rotated by 270°) 6.5 Mounting options The device can be mounted without the accessories. u For installation, please use the threaded sleeves on the back of the device.

DTI801 DTI901 DTI911 DTI961 The smaller the set data length, the less time the device needs to perform an operation. As a result, the ID tag's dwell time in the detection zone is shorter.
DTI801 DTI901 DTI911 DTI961 The message is transmitted as a process value until the controller confirms the block counter. The controller confirms the block counter by mirroring the block counter value in the output image. If there is no confirmation, the message is automatically confirmed after the data hold time has expired and the new message is transmitted. The rapid changing of ID tags generates many messages in a short time.
