2. In the window that opens, enter a path/file name at the bottom o f the window.
3. Select the second device.
4. Click the OK button. The file generates, and the differences are highlighted in red, which is for the first device.

11.8 Back up and restore settings

Back up a copy of the in-service settings for each commissioned UR device, so as to revert to the commissioned settings
after inadvertent, unauthorized, or temporary setting changes are made, after the settings defaulted due to firmware
upgrade, or when the device has to be replaced. This section describes how to backup settings to a file and how to use
that file to restore the settings to the original relay or to a replacement relay.

11.8.1 Back up settings

The following file types can be saved:
• URS — UR settings file — When the IEC 61850 option is not present
• IID — Instantiated IED capability description file — Actual settings on UR
• ICD — IED Capability Description file — Default settings on UR
• CID — Configured IED description file — Settings sent to the UR (may or may not contain the present settings)
UR device settings can be saved in a backup URS file using the EnerVista UR Setup software. The URS file is the standard
UR settings file. For an introduction to settings files in the URS format, see the beginning of the Interfaces chapter.
When the IEC 61850 option is present, the settings can be saved alternatively in a backup IID file either using the EnerVista
UR Setup software in online mode or by using any of the supported file transfer protocols. The IID file is one of several IEC
61850 Substation Configuration Language (SCL) file types; see the IEC 61850 chapter in the UR Series Communications
Guide for an introduction to SCL.
"TBD" displays when a setting in a modeled element is configured with a non-modeled operand. For example, Phase IOC is
modeled in a firmware release, while the LED operands are not modeled. If the block setting of the Phase IOC is configured
with LED operands, its displays as TBD in IID and CID files, the web interface, or in an MMS client.
The options that display in the EnerVista software when right-clicking depend on device options.
Preferences are set in the File > Preferences > IEC 61850 menu. There are two options as follows:
• Preserve custom attributes when importing SCD/CID files — Applies to the Add Device to Offline Window option.
When enabled, the IID file also is to be copied to the computer. The IID file that is retrieved from the relay is therefore
assumed to be in synchronization with the resulting .urs file, and in fact in this situation the IID file on the computer is
a copy of the IID file that was read from the online device. When disabled, the IID file on the computer is to be left
unchanged. The location of the IID file is C:\ProgramData\GE Power Management\urpc\Offline, for example.
• Do not update IID file when updating SCL files — When enabled (default), an IID file is not to be created on the
computer and if one is already present there, it is neither removed nor updated. Have this option enabled when you
want to keep the IID file from the UR device instead of from another tool. The location of the file is C:\ProgramData\GE
Power Management\urpc\Offline, for example.
An Environment backup stores a list of sites and devices in the Online and Offline Window areas. Settings files are not
contained within the environment file. If a settings file is moved, renamed, or deleted after the backup, it is removed from
the Offline Window during the restore.
To save a settings file in the URS format in EnerVista Online Window:
1. In EnerVista, connect to the device in the Online Window area.
2. Right-click the device name in the Online Window area and select Add Device to Offline Window. A window opens.
3. Select or enter a file name and location, and click the Receive button. A .urs file is created in the Offline Window area.
