3 Functions and features
In combination with the IO-Link master the read/write head DTI430/DTI431 is used
for non-contact reading and writing of RFID tags that conform to the system�
The data is available as process data at the IO-Link interface�
4 Functions
4.1 Operating principle
The ID tags are operated passively, i�e� without battery� The energy required for
operation is supplied by the read/write head�
The physical principle of the energy transfer is based on 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�
