If the ID tag leaves the detection zone, the data bytes remain constant in the process image in
accordance with the data hold time. After the data hold time has elapsed and when the ID tag leaves
the detection zone, the data bytes in the process data input image are reset to “0x00”. If the ID tag
remains in the detection zone, the re-writing of the data is triggered by setting the status bit “Cmd
Start”.
If the bytes to be written already exist on the ID tag, the write command is not executed and not
acknowledged.
In the operating mode “WRITE DATA AUTO”, writing is executed on all detected ID tags,
independently of the EPC. The ID tag selection (Ò ID tag selection/41) and RSSI filter (Ò
RSSI filter/42) functions are used for selection.
Under adverse conditions, write operations are repeated. The block counter then does not
correspond to the number of ID tags in the detection range.
The smaller the set data length, the less time the device needs to perform an operation. As a
result, the ID tag's dwell time in the detection zone is shorter.
