Detailed product information
Turck’s HF Bus Mode Enables up to 128 Read/Write Devices to be Connected on Four RFID Ports
Turck’s TBEN-L-RFID interface combines easy handling with the rapid integration of the compact TBEN-S-RFID and the robustness of the larger TBEN-L design. Its HF bus mode can connect up to 32 compatible HF read/write devices in series on each port. This reduces the wiring effort and costs required in applications involving a large number of read and/or read positions.
Several predefined commands and operating modes for the most common application scenarios reduce the programming required in the PLC. Filters and different data export options also often make any middleware unnecessary. The mixed operation of HF and UHF read/write heads is also possible.
Key Facts
Up to 32 bus-compatible read/write devices per RFID channel can be connected to the TBEN module
Depending on the number of read/write heads connected additional power supply may be required
By default, a command can only be processed by one read/write device, 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 devices in a bus topology
HF bus mode does not require any point-to-point connection
Available for RFID interfaces TBEN-L, TBEN-LL, TBEN-S and TBEC-LL
Applications:
HF bus mode is suitable for all applications with a high amount of RFID read/write Points. Without HF bus mode these applications are usually not only comparatively expensive in hardware due to the interface modules, but also complex to install and maintain.
