If the device is operated with a 10 Mbit/s-only hub, the link speed should be switched from
Auto Detect
to
10Mbps/Half-Duplex
. With modern 100/10 Mbit/s switches, this setting
can be left at its default.
The settings for DNS and NTP servers should be made in the IP host settings (see Section
6.2.6). In case an IP interface runs DHCP, the DNS and NTP addresses supplied by DHCP
can be seen here. Models with one Ethernet port only do not have these settings here.
Other standard protocols that are bound to the Ethernet interface are FTP, Telnet, and
HTTP (Web server). By deselecting the checkbox, those protocols can be individually
disabled. The standard UDP/TCP ports can be changed in the respective protocol settings.
An example for the FTP server is shown for FTP in Figure 55. The FTP server is used for
instance to update the firmware. Note that HTTP for the Web server can only be disabled
on the console interface.

6.2.5 Using Multiple IP Ports
On models with multiple IP interfaces, the port configuration provides a separate port tab
for each IP port, e.g.,
Ethernet 1 (LAN)
and
Ethernet 2 (WAN)
. In the port mode setting
these interfaces can be enabled to operate as a separate IP network. As a default only
Ethernet 1 (LAN)
is enabled and configured to be switched with the Ethernet 2 port. To
enable
Ethernet 2 (WAN)
as a separate, isolated IP network, choose
Separate network
in
the port mode setting as shown in Figure 56 and save settings. A reboot is required to make
this change effective.
For each IP interface configured as a separate network, the various standard protocols can
be enabled separately. As a default, the secure protocols HTTPS, SSH and OPC UA are
enabled on a new separate IP interface. Some protocols can be enabled on multiple
interfaces at the same time, others on one interface only. If one of the latter is enabled on a
new separate IP interface, a warning will be displayed, stating on which other interface the
protocol will now be disabled (e.g., CEA-709 over IP).
The separate network mode can be used, if you want to operate an isolated building network
on the LAN and expose some aspects outside the building network (denoted as WAN).
Physically, the two Ethernet ports will be plugged into different Ethernet switches.
