RFID Read/Write Devices with IO-Link


Turck is presenting three new RFID read/write devices with IO-Link in M18 and M30 threaded barrel and Q40 rectangular designs. RFID can now be effortlessly integrated into Existing IO-Link applications with the new devices. The fast COM3 interface and 32-byte process data width enable the HF readers to significantly 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 decentralized or autonomous applications because you do not require a master, an RFID interface or a controller. With this feature you can ensure that only authorized persons have access to storage and retrieval machinery.

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, parameterization and function testing is possible via their web interface without additional tools.
