BACK UP AND RESTORE SETTINGS

10.1.3 Unscheduled maintenance (system interruption)

1. View the event recorder and oscillography or fault report for correct operation of inputs, outputs, and elements.
10.2 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.

10.2.1 Back up 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 alternatively be saved 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 an IEC 61850
Substation Configuration Language (SCL) file; see the IEC 61850 chapter in the UR Series Communications Guide for an
introduction to SCL.
The options that display in the EnerVista software when right-clicking depend on device options.
To save a settings file in the URS format:
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 Device Settings. 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 save settings in the IID format in EnerVista:
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 using TFTP:
1. On a computer on the same subnetwork as the UR device, open a command window.
2. Enter
TFTP <IP address> GET ur.iid <destination>
where
<IP address> is the IP address of the UR device
ur.iid is the internal name of the IID file in the UR device
<destination> is the path and file name of the IID file. If omitted, the file is saved as ur.iid in the command window
default directory.
An example is
TFTP 192.168.1.101 GET ur.iid Feeder1.iid
