Network Security and Firewalls
Setting up an intranet through a global address involves network security con-
siderations. Before doing so, be sure to consult with a network specialist and
consider installing a firewall.
Once a firewall has been set up by a communications company, on the other
hand, there may be some applications that cannot be used. Be sure to check
first with the communications company.

The PLC can send the Ethernet Unit's IP address to the SMTP server by
mail via the intranet.
The PLC can receive the Ethernet Unit's IP address from the POP3 server
by mail via the intranet.
The PLC can acquire clock data through the Ethernet Unit's IP address
from the SNTP server via the intranet.
The PLC can acquire the server IP address for the Ethernet Unit's IP ad-
dress from the DNS server via the intranet.
