8.7.1 Ethernet
Ethernet is the most widely used standard for local networks
(LAN). The standardisation of this technology has created some
of the easiest and cheapest ways of creating communication
between electric units, for instance between computers or between
computers and control units.
The webserver of CU 352 makes it possible to connect a computer
to CU 352 via an ethernet connection. The user interface can
thus be exported from CU 352 to a computer so that CU 352
and consequently the system can be monitored and controlled
externally.
We recommend that you protect the connection to CU 352
according to your safety requirements in consultation with
the system administrator.
In order to use the webserver, you must know the IP address
of CU 352. All network units must have a unique IP address to
communicate with each other. The IP address of CU 352 from
factory is 192.168.0.102.
Alternatively to the factory-set IP address, it is possible to use a
dynamic assignment of IP address. This is possible by activating a
DHCP (Dynamic Host Configuration Protocol) in CU 352 or via the
webserver. See the example in figure below.
Example of setting of ethernet
Dynamic assignment of an IP address for CU 352 requires a DHCP
server in the network. The DHCP server assigns a number of IP
addresses to the electric units and makes sure that two units do not
receive the same IP address.
A standard internet browser is used for connection to the webserver
of CU 352.
If you want to use the factory-set IP address, no changes are
required in the display. Open the internet browser and enter the
IP address of CU 352.
If you want to use dynamic assignment, you must enable the
function by selecting Use DHCP and clicking [ok]. A check mark
shows that the function has been enabled.

Open the internet browser and enter the host name of CU 352
instead of the IP address. The internet browser will now try to
connect to CU 352. The host name can be read in the display, but
can only be changed by either a GSC file (configuration file) or via a
webserver. See section Change of network
A host name is required to use DHCP.
This is the first display shown when connecting to CU 352.

User name: admin
Password: admin
When you have entered the user name and password, an
application starts up in CU 352, provided that a Java Applet has
been installed on the computer. If this is not the case, but the
computer is connected to the internet, then use the link on the
screen to download and install the Java Applet.
The application on CU 352 exports the Java Applet to your browser
and gives you access to user interfaces such as display and
operating panel.
The Java Applet installation in the browser must be accepted by the
user. You can now monitor and control CU 352 from a computer.
