Omron V680S Series User Manual

Section 2 Functions
 Field Extension Mode
You can use this mode to link Reader/Writers in order to extend the effective communications field.
Even if the workpieces are not all the same height or not oriented in the same direction, the placement
of more than one Reader/Writer enables communicating with the RF Tags without worrying about the
positions or orientation of the RF Tags.
This enables communications over a wide communications field and is therefore recommended for
applications in which the locations or orientation of the RF Tags is not consistent.
If you use Field Extension Mode, you can use only three RF Tag communications commands: READ
DATA, WRITE DATA, and READ ID. Also, you can specify only the Once or Repeat communications
option. If you use the FIFO Repeat communications option in Field Extension Mode, an execution
status error will be indicated in the response.
Applicable RF Tag Communications Commands
Applicable Communications Options
