PRODUCT SETUP CHAPTER 5: SETTINGS
The IEC 61850 window is divided into a navigation pane on the left and a settings panel on the right. You expand and click
an option on the left to display its panel on the right. The following figure shows an example for Server Configuration. The
SETTING column contains the names of the settings, and the PARAMETER column is used to enter the settings. Hovering
the mouse over a setting name displays a tool-tip showing the 61850 information model name of the setting or its location
in SCL files.

Opening the IEC 61850 window while online causes the UR Setup software to retrieve and import an SCL file from the G30.
This System Configuration Description (SCD) file contains all the settings in the UR at the time of the file request, both those
that are mapped into the IEC 61850 information model (that is, the "public" sections) and those that are not in the model
(that is, the "private" section). The UR EnerVista Setup software imports all of these settings into the current session, not just
those in the IEC 61850 window. To avoid loss of any unsaved setting changes made in other panels during the current
session, all other panels for the G30 must be closed before the IEC 61850 panel can be opened, and the software prompts
for this when applicable. Panels for other devices can be open concurrently to facilitate parameter coordination.
When CyberSentry security is enabled, editable settings depend on the user role logged in. For example, an Administrator
and Engineer can change settings. If prompted for a "Settings password," it means the Administrator or Engineer
password.
The Restore button restores settings in the window to their last saved values. The Default button reverts settings in the
window to factory default values or Oscillography, Data Logger, or FlexLogic Equation Editor pre-configured values. The
Reset button reverts all IEC 61850 settings to the factory default values, not just the current window. (In other settings
windows, the button reverts settings in the window to factory default values.)
When a setting is enabled, its panel continues to read Disabled until relaunched. There is no polling capability to update
automatically the IEC 61860 readings, so the panel needs to be closed then opened for the correct status to display. Good
practice is to close any panel not in use because changes being made by other users too are reflected only upon relaunch
of the panel.
Some of the IEC 61850 settings use floating point data, which guarantees accurate representation of real numbers up to
seven digits. Numbers with more than seven digits are approximated within a certain precision. This can result in
differences between what is entered and what is saved, and for example results in differences shown on a settings
comparison report.
