Functions

Communications Mode

The ID Flag Sensor operates after reading the setting of the mode setting switches when the power supply is
turned ON. Set the mode for communications with the RF Tags or set the Noise Measurement Mode on the
access mode setting switch. There are three communications modes, each with different timing for completing
communications with RF Tags: Mode 1, Mode 2, and Mode 3. Also, each of these modes has two other modes
to specify when to start communications with the RF Tags: Trigger Mode and Auto Mode. Mode 2 and Mode 3
are compatible with the V600 series.

Trigger Mode
In Trigger Mode, an RF Tag on a workpiece or pallet in the communications area of the Antenna is
detected by a sensor or a switch. A control signal (called the trigger signal) is output from the PLC to
the ID Flag Sensor to trigger the ID Flag Sensor to begin communications with the RF Tag. The ID Flag
Sensor reads the RF Tag data and outputs the results to the PLC.
PLC
Only one Interface Cable (I/O connector CN1) is used to read RF Tag data. The address shift, noise check, and parity
check functions, however, are not possible when only CN1 is used.
