7 Ethernet/IP Communications
7 - 4 UHF RFID System V780-series Reader/Writer User’s Manual (EtherNet/IP
TM
) (Z402)
This section describes how to set data links for EtherNet/IP.
The communications areas in the PLC for which data links are created to the Reader/Writer are speci-
fied as tags and tag sets, and the connections are set for tag data link communications.
To connect to OMRON PLCs or Controllers, you use the Network Configurator to set up tag data links
(i.e., tags, tag sets, and connection settings). Refer to the following manuals for details on the tag data
link settings that are made with the Network Configurator.
