OSCILLOGRAPHIC, FAULT, AND OPERATION RECORD RETRIEVAL USING THE FTP
BROWSER.
Oscillographic records can be extracted from the TPU2000R by using a standard web browser from Netscape or
Internet Explorer Version 5.0 from Microsoft, from an initiated FTP session. The waveform file will be in Comtrade
file format and can be immediately imported by ABB's Wavewin package for examination by the user.
Since theTPU 2000R Ethernet card is both a client and a server, the TPU 2000R can act as an FTP server for
data file storage.
