Conditions for Communications Applications
If the built-in EtherNet/IP port uses a private address, you can use explicit message communica-
tions service under the following conditions.
•
The explicit message communications service can be executed on the intranet between built-in
EtherNet/IP ports with private addresses only.
•
A device such as a personal computer (CIP applications including the Network Configurator) can-
not connect online and communicate over the Internet with a built-in EtherNet/IP port that has a
private address. Explicit message communications are also not possible over the Internet
between built-in EtherNet/IP ports with private addresses.

Network Security and Firewalls
To set up an intranet through a global address involves network security considerations. Be sure
to consult with a network specialist in advance and consider installation of a firewall. After a fire-
wall has been set up by a communications company technician, there may be some applications
that cannot be used. Be sure to check first with the communications company technician.
