Turck RFID read/write devices with IO-Link

Turck has announced three RFID read/write devices with IO-Link in M18 and M30 threaded barrel and Q40 rectangular designs. RFID can now be integrated into existing IO-Link applications. The fast COM3 interface and 32-byte process data width enable the HF readers to improve the performance of IO-Link RFID systems. The devices also provide the option of password-protected access to data carriers and RSSI signal strength recording for continuous quality control. The read/write devices can be operated in IO-Link mode or in standard I/O mode (SIO mode).

In SIO mode, the devices still provide the password protection function for access control. This function is particularly useful for decentralised or autonomous applications because a master, RFID interface or controller is not required.

Permanent measurement of the signal strength (RSSI) enables monitoring of the functional reserve in the RFID application. If a defined threshold value is not met, the alarm output switches, enabling early detection of range loss in tags or other disruptive factors such as interference from metals. This condition-monitoring function can also be easily retrofitted in existing applications.

Device parameters are easily set with Turck’s IO-Link masters since these already contain the stored IODD. All three read/write devices — TN-M18-IOL2, TN-M30-IOL2 and TN-Q40-IOL2 — utilise the same IODD. In addition, configuration, parameterisation and function testing is possible via their web interface without additional tools.
