SECTION 6
Controlling the ID Sensor Unit
Copy (Two-channels ID Sensor Units Only)
This command is supported by Two-channels ID Sensor Units only. Data is read from the RF Tag for
one Antenna and written to the memory of an RF Tag in the interrogation zone for the other Antenna.
Writing to the second RF Tag is always performed with a trigger
• If the Command Execution Bit is turned ON in the Unit Controls for Antenna 1, data will be read from the RF Tag for
Antenna 1 and written to the RF Tag for Antenna 2.
• If the Command Execution Bit is turned ON in the Unit Controls for Antenna 2, data will be read from the RF Tag for
Antenna 2 and written to the RF Tag for Antenna 1.
• The Communications Specification for the Antenna that writes data will always be a trigger regardless of the specified
communications method.
• The Status Flag (CIO n+8, bit 04) in the Results Information will turn ON if an error occurs in the Antenna that writes
data.
• Confirm that the Antenna that writes data is not communicating before turning ON the Command Execution Bit. If the
Antenna that writes data is communicating, the Status Flag (CIO n+8, bit 04) in the Results Information will turn ON.
• Confirm the capacity of both the RF Tag being read and the one being written before using this command. If the
Processing Address and Number of Processing Bytes for the Antenna that write data are not suitable for the RF Tag
being communicated with, the Status Flag (CIO n+8, bit 04) in the Results Information will turn ON.
