functions that require a DNS server, so these settings are not used. (The
functionality required to use a DNS server is not provided on EtherNet/IP
Units with unit version 1.0. The DNS server cannot be used with these Units.)
Sets the domain name of the domain to which the EtherNet/IP Unit or built-in
EtherNet/IP port belongs. The EtherNet/IP Unit or built-in EtherNet/IP port
does not use a domain name in actual communications.
Set the IP router table to route EtherNet/IP communications for specific nodes
through an IP router other than the default gateway.
The following settings are provided on the Ethernet Tab Page of the Unit

tings of the connected switching hub. If the settings do not match, the link will
become unstable and prevent normal communications. The following table
shows the allowed settings for each switching hub communications mode.
Use the Network Configurator to change IP address settings for any device
other than a CS/CJ-series EtherNet/IP Unit or built-in port. You can also use
the Network Configurator to change IP address settings for a CS/CJ-series
EtherNet/IP Unit or built-in port.
