4. CONFIGURATION

4.14.2.2. Network Configuration

On this page you can manually enter the parameters for
your corporate Ethernet connection:
• IP Address: corporate network address that is as-
signed to the controller. It must be unique.
• Subnet: subnet mask.
• Gateway: device address (such as a router) that con-
nects the controller network to other external networks.
• DNS: Domain Name Server address.
By touching one of these fields (single box), a virtual key-
board appears where you can edit the field value.
Ask your network administrator for the addresses and pa-
rameters to use to connect the multi-purpose controller to
your corporate network.
Enable DHCP enables the (Dynamic Host Configuration
Protocol). DHCP automatically retrieves information (IP
Address, Subnet, Gateway, DNS) required for network
connection. By enabling DHCP, a message appears when
saving that warns you to restart the controller. Touch the
Yes button to reboot, No to cancel the operation. After re-
booting, with the DHCP enabled, the configuration param-
eters recovered by DHCP appear in the various fields (IP
Address, Subnet, Gateway, DNS).
The Save and Cancel buttons appear when changes have
been made and allow them to be saved or cancelled, re-
spectively, leaving the previous configuration.
The NTP VNC Configuration button opens the page to
configure these two services.
The HOME button returns to the SETUP sub-menu and
BACK to the previous page.

4.14.2.3. Network NTP and VNC Configuration

Enabling NTP (Network Time Protocol) the controller's
internal clock is constantly synchronised to the time of an
external NTP server. When the external signal stops, for
any reason, the controller continues to operate using the
72
internal clock. As soon as the connection to the NTP server
is restored, the internal clock re-synchronises.
The address of the NTP server can be entered in the appro-
priate field both as a name and as an IP address.
The following table lists some free-to-use NTP servers.
Other servers may also be used, provided they conform to
the NTP standard. If an internal server is used, the Gateway
must be configured correctly.
Note
If the NTP function is active and the connection is interrupt-
ed, no error message will appear on the instrument
Server address
time.google.com
it.pool.ntp.org
europe.pool.ntp.org
The current time and date are displayed on the right while
on the left you can set the time difference with the Green-
wich time (GMT, same as the USC) with the + and - but-
tons.
There is no automatic notification of daylight savings time.
Enabling the VNC (Virtual Network Computing) you can
control the controller from a computer that has access to
the Ethernet network on which the controller is connected.
More information on the VNC is available in paragraph "2.5.
Ethernet Connections" on page 23.
Enter the password that will be used by VNC clients to au-
thenticate with the controller. The password can be from 1
to 34 characters, freely chosen from those displayed on the
keyboard.The terminal must be restarted after enabling.
The Save and Cancel buttons appear when changes have
been made and allow them to be saved or cancelled, re-
spectively, leaving the previous configuration.
The HOME button returns to the SETUP sub-menu and
BACK to the previous page.

4.14.2.4. Display Configuration

Changes the brightness of the screen and the screen saver
timer.
To edit the set value, use the - and + keys.
A time of 0 seconds as the screen saver time always leaves
