ID Sensor Unit Functions
Trigger
When a trigger is specified, communications are performed with the RF Tag when the Command
Execution Bit (CIO n, bit 0) in the Special I/O Unit Area turns ON and command execution is ended
when communications have been completed. If there is no RF Tag in the interrogation zone when the
Command Execution Bit turns ON, RF Tag Missing Error Flag (CIO n+8, bit 10) in the Results
Information in the Special I/O Unit Area will turn ON and an error code (E072) will be stored in the
Processing Results Monitor (CIO n+9). Use a sensor or other method to detect the presence of an RF
Tag before turning ON the Command Execution Bit.
