4.2.3 System settings
This is the menu item where adjustments can be made to some device settings. This menu item
can be password protected. The text fields, list boxes, and check boxes are almost the same as
in the parameters menu item except for one type of text field, the IP address field, which is found
only here in the system settings menu item.

The behavior of the system Settings sheet is very similar to the Parameters sheet. The short
description of the system settings are as follows:
System parameters -
This field is used for front panel control and power system frequency
settings.
Station bus settings
- This field includes settings for the IPv4 based communication like IP
address, IP address mode, redundancy mode, mask, gateway, and DNS addresses. The
DHCP server function can be switched on with a combo-box.
Warning: do not use the DHCP server function when other DHCP server is already in use on
the network, as it may cause serious communication failures!
Ethernet communication -
The device can communicate using several Ethernet based
protocols at the same time. Only the IEC61850 communication is licensed, all the other
protocols are available by default. The GOOSE repeat rate combo-box can be used for
adjusting T0 time of the Generic Object Oriented Substation Event messages.
Serial communication -
Only one protocol can be selected for serial communication
purposes, physical parameters can be set in this field. Note that serial communication needs
appropriate CPU card.
Time synchronization -
The device handles broad range of time synchronization protocols:
NTP server (SNTP), serial communication, and different pulse inputs. If Time sync. warning
parameter is enabled and the device is not synchronized, an alarm is raised (status LED
goes yellow).
Time zone settings -
Use this field to set the offset to the GMT time and the settings of
daylight saving.
LCD backlight -
Parameters in this field control the behavior of the LCD panel. Backlight will
switch off after its timeout. The Backlight group is useful if you have more than one device
close to each other. Touching one of them will switch on the LCD screen of all devices that
belong to the same group.
System services -
Use this field to set the web interface mode, enable secure file transfer
mode, discover devices on the local network, set up remote login feature and log server.
Client whitelist -
If this function is enabled, only the allowed clients can access the device
in the selected role.
More information can be found under the question marks located in line with the actual setting.
