6-10 Multi-Reader/Writer Function
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.
In the Multi-Reader/Writer function, the slave Reader/Writers connected to the master Reader/Writer
are differentiated by the following Reader/Writer numbers.
Precautions for Correct Use
• When using this function, the Reader/Writers connected by the Multi-Reader/Writer function
must all be Version 3.0 or later.
• When using this function, the Reader/Writers connected by the Multi-Reader/Writer function
must all be the same model (country of specification).
• The Slave Reader/Writer (V780-HMD68-ETN-
-S) does not accept communications com-
mands or Reader/Writer setting commands.
* 1
Also, it does not accept Modbus/TCP port connection from other than the Master Reader/ Writer.
* 2
*1. When using a standard Reader/Writer (V780-HMD68-ETN-
) as a slave Reader/Writer, the Getting
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.
• The Modbus/TCP port number of the slave Reader/Writer must be set the default (502).
When changed, "Communications error between Reader/Writers (200B hex)" is detected.
