TCP/IP and Link Settings Section 3-8
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.)
Domain Name
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.
IP Router Table
Set the IP router table to route EtherNet/IP communications for specific nodes
through an IP router other than the default gateway.
Settings on the Ethernet Tab Page
The following settings are provided on the Ethernet Tab Page of the Unit
Setup for the EtherNet/IP Unit or built-in EtherNet/IP port.
• Link settings (baud rate and half/full duplex)
Link Setting
Sets the communications baud rate.
Note Adjust the EtherNet/IP Unit’s link settings to match the communications set-
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.
Note Best = Recommended; OK = Allowed; --- = Not allowed.
3-8-2 Making TCP/IP Settings with the Network Configurator
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.
1,2,3... 1. Connect the Network Configurator online.
Refer to 6-2-9 Connecting the Network Configurator to the Network for
details on connecting the Network Configurator to the EtherNet/IP Unit.
Setting Meaning
Auto (default) The baud rate with the switching hub is detected automat-
ically. If possible, the Unit operates in 100Base-T (full
duplex).
10 Mbps, Half Duplex Operates in 10Base-T, half duplex.
10 Mbps, Full Duplex Operates in 10Base-T, full duplex.
100 Mbps, Half Duplex Operates in 100Base-TX, half duplex.
100 Mbps, Full Duplex Operates in 100Base-TX, full duplex.
