Ethernet Address Notation
A specific Ethernet address is allocated to all devices connected to the Ether-
net network. The EtherNet/IP Unit’s address is listed in 12-digit hexadecimal
on the right side of the Unit.
Note
(1) The Ethernet Address can also be checked with the CONTROLLER
DATA READ command. For details, refer to Appendix E FINS Commands
Addressed to EtherNet/IP Units or Built-in EtherNet/IP Ports.
(2) An IP address label is included with the EtherNet/IP Unit, so the user can
record the user-set IP address and subnet mask on the label, and affix
the label to the front of the Unit. When this label is affixed to the front of
the Unit, it is easy to confirm the Unit’s IP address and subnet mask.
