10.7 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.
10.7.1 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.
