6-10 Multi-Reader/Writer Function

6-10-1 Outline

The Multi-Reader/Writer function allows connection to multiple Reader/Writers, and performs com-
munications with RF Tags.
It can connect to a maximum of eight Reader/Writers, and performs master/slave control with one
Reader/writer as the master, and the other Reader/Writers as slaves. Because multiple slave
Reader/Writers can be jointly controlled simply by controlling a master Reader/Writer, it is possible
to easily perform complicated controls from the host device.

mands or Reader/Writer setting commands.
Also, it does not accept Modbus/TCP port connection from other than the Master Reader/ Writer.

command will be accepted.
*2. Connection from the web port will be accepted.
• The slave reader/writer (V780-HMD68-ETN--S) can not be used as a master reader/writer.

When changed, "Communications error between Reader/Writers (200B hex)" is detected.
