The SETTING_CHANGES.LOG file stores all the setting changes. A total of 1024 events are stored in a circular buffer in non-
volatile memory.

10.4 Convert device settings

Settings files can be upgraded or downgraded to other firmware versions. For example, version 7.4 settings can be
upgraded to version 7.6.
Settings are reset to factory default upon conversion.
When using IEC 61850, additional configuration is required. Contact GE for guidance before converting settings.
To convert settings:
1. If not already in the Offline Window area, right-click the online device in the EnerVista software and select the Add
Device to Offline Window option. This copies the settings to the Offline Window area. Any message about file repair
usually means that settings were missing in the original file and have been added with default values to the new file.
2. Make a copy of the settings file in the Offline Window area by right-clicking the file and selecting Duplicate Device. A
copy of the file is made and the file name start with "Copy of." Optionally rename the file by right-clicking it and
selecting the Rename Device option.
3. Convert the settings by right-clicking one of the files in the Offline Window and selecting the Convert Device Settings
option.
GE recommends converting settings in firmware steps, for example when converting from 6.0 to 7.4x, convert first to
7.0 then 7.4 in order to follow embedded conversion rules and keep settings.
The settings convert and a report generates.
