RF Tag
(V680 Series and V680S Series)
Ethernet Cable (Max. length: 100 m)
(Recommended: XS5W-T42 - MC-K from OMRON)
Power Cable
(Recommended: XS5F-D42 - 80-F from OMRON)
Connect the Ethernet Cable to a host device (e.g., Switching Hub or PLC) that supports STP and ground the host device to
100 Ω or less.
Always use a Switching Hub on any network where tag data links are used.
If you use a repeater hub on a network on which EtherNet/IP tag data links (cyclic communications) are used, the network
communications load will increase causing frequent collisions and unstable communications.
Use a host device (PLC) that can set connections as the originator (i.e., the side that requests opening a communications line for
tag data links).
