Read/Write Functions
 Read/Write Command Processing
The normal (not auto) read/write functions are used for communications with Tags within a fixed area.
Therefore, check that the Tag is within the Antenna's communications area before sending read/write
commands. If a Tag is not present, a Tag missing error response will be returned.
1. Confirm that the Tag is within the
communications area before sending the
command from the host device.
2. The ID Controller performs read or write
processing according to the command.
3. After processing has been completed, the ID
Controller returns a processing completed
response to the host device. The host device
receives the response and then moves the
workpiece (with Tag) along the production line.
Auto Read/Write Functions
 Auto Command Processing
The ID Controller does not return a response for AUTO commands until a Tag is within range. The
communications path with the host device is busy during this time.
1. An AUTO command is sent for an Antenna from
the host device.
2. The ID Controller does not return a response
while the Tag is not in range, so the host device is
in busy status.
3. Read or write processing is performed when the
Tag passes in front of the Antenna.
4. After processing has been completed, the ID
Controller sends a processing completed
response for the AUTO command to the host
device.
