PRODUCT SETUP
(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 L30 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.
Create CID and settings files
When the Save button is clicked in the online IEC 61850 window, UR Setup software prepares a configured IED description
(CID) file containing all the settings of the UR and sends the CID file to the L30. Upon receipt, the L30 checks the CID file for
5
correctness, going out of service, then back into service when the CID file is accepted. The software displays a message
when the L30 is running the new settings, confirming successful transfer. This process can take a minute or so due to the
amount of processing required by the software and the L30.
Certain settings not related to IEC 61850 are indicated in this instruction manual as taking effect only when the device is
restarted, for example using the Maintenance > Reboot Relay Command in the software.
When the Save button is clicked in the offline IEC 61850 window, UR Setup software saves to local storage, for example the
hard drive, a .urs file containing all settings of the UR.
View IID/CID files
The file types are described as follows:
• IID — Instantiated IED capability description file — Actual settings on UR
• CID — Configured IED description file — Settings sent to the UR (may or may not contain the present settings)
IID and CID files are viewable. For example, after modifying settings in the IEC 61850 panels and clicking Developer IID/
CID Viewer in the software, a CID file generates and an SCL Viewer shows the updated CID file content. There are no edit
or save functions; use instead the Back Up and Restore Settings instructions later in this document to save the files.
Searches are case insensitive.
