• An internal run-time Event Log created by the Archiver, that records all the
operations performed by the Archiver.
Documented in this Event Log is:
•
Communication failures between the Archiver and the DDFRs.
•
Communication re-connects between the Archiver and the DDFRs.
•
Date and Time of each instance of data archiving from each of the
DDFRs.
Once the Archiver has archived data from a DDFR to its storage location, the original data
on the DDFR is not deleted. The function of cleansing the data on the DDFR is undertaken
by the DDFR’s automatic record clearing function.

Archiver Directory and File Structure
The DDFR Archiver stores the retrieved files in a defined directory structure that branches
out from a Root Folder, which you can configure (see section 5.2.3 below).
The Root Folder is
defaulted
to:
C:\Documents and Settings\All Users\Documents\GE Power
Management\DDFRArchiver\Data\
<DDFR folders>
Below the Root Folder, a separate folder is created for each DDFR. Each folder name uses
the exact name of a DDFR.
Within each DDFR folder there are three folders:
1.
<DDFR name>\Waveforms
: Contains the CFG, DAT and HDR files created for
each oscillography record generated by any relay.

files use the following naming convention:
