6. HOW TO COMMUNICATE WITH ID TAGS
6.3.3 Repeat auto
With the repeat auto communication specification, communication is performed while
the ID tag is being moved.
Communication is performed with the ID tags that enter the antenna communication
area one after the other, until the ID command execution request (RYn4) is turned OFF.
1. When the ID command execution request (RYn4) is turned ON, ID-BUSY (Rxn3) is
turned ON and ID tag detection is started.
2. When an ID tag enters within the antenna communication area, communication with
the ID tag is started.
3. After communication with the ID tag ends, ID command complete (RXn4) turns ON.
4. When result reception (RYn6) is turned ON, ID command complete (RXn4) turns OFF
and detection of the next ID tag within the antenna communication area is started.
5. Subsequently, Steps 2 to 4 are repeated.
6. When the ID command execution request (RYn4) is turned OFF, ID-BUSY (RXn3) is
turned OFF and ID tag detection is ended.
7. With the repeat auto communication specification, communication cannot be
performed normally, bit 12 of the error details storage area (RWrm+1H) turns ON,
and error detection (RXn5) turns ON when multiple ID tags are within the antenna
communication area at once. Thus, make sure there is only one ID tag within the
antenna communication area.
If the time set in the auto system command wait time setting area (RWwm+3H)
elapses during waiting for the communicable ID tag, bit 10 of the error details
storage area (RWrm+1H) turns ON and error detection (RXn5) turns ON.
