CHAPTER 11: MAINTENANCE
BACK UP AND RESTORE SETTINGS
L30 LINE CURRENT DIFFERENTIAL SYSTEM – INSTRUCTION MANUAL

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.
To create a new settings file in the URS format in EnerVista Offline Window:
1.
In EnerVista, right-click in the Offline Window area and select
New Device
. A window opens.
2.
Change the file name at the end of the
Path
field, keeping the .urs extension.
3.
From the
Associate File with Device
drop-down list, select the UR device. Other fields complete automatically.
Otherwise, when you do not select a device from the drop-down list, all fields need to be completed manually and
only devices that match the entered order code and version display in the list.
4.
The
Serial # Lock
field is the serial number of the intended device. It ensures that the settings file is sent only to the
specific relay that matches the serial number.
5.
Click the
OK
button to create the .urs file in the Offline Window area.
To save settings in the IID 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
Read IID File
. The option is not present when the
device does not have the IEC 61850 option. A window opens when successful.
3.
Select or enter a file name and location, and click the
Receive
button. A .iid file is created.
To save settings in the IID format in EnerVista Offline Window:
1.
In EnerVista, right-click the device in the Offline Window area.
2.
Select the
Create IID File
option for firmware below 7.3. The option is not always available. Select the
Save As
option
for firmware 7.3 and later, and select the IID option from drop-down list.
