Some parameters have an edit-copy. If editing is cancelled, the values with an edit-copy
are immediately restored to the original value. The values without an edit-copy, such as
string values, are restored to the original value only after a reboot even though the edited
value is not stored in the flash memory.
1. Click Write to IED after editing parameter values to put the values into protection
relay's database for use.

The values are not stored to the flash memory.
2. Click Commit to write the values to the flash memory.
• Click Reject to cancel saving settings.
• If the parameter has an edit-copy, the original parameter value is
restored.
• If the parameter does not have an edit-copy, the edited parameter value
remains visible until the protection relay is rebooted. However, the
edited value is not stored in the nonvolatile memory and thus the reboot
restores the original value.
