ASCII Command Reference
Command Description
The following examples illustrate some possible option combinations.
EXIT
Use the EXIT command to terminate a Telnet session and revert to Access Level 0
(exit relay control).
FILE
The FILE command provides a safe and efficient means of transferring files
between IEDs and external support software (ESS) by providing Ymodem file
transfer. The FILE commands are especially useful for retrieving high-resolution
sampled data in binary COMTRADE format from the relay.
All text enclosed in [brackets] indicates optional command line parameters. The
specific directories available in the relay depends on the relay model, but typi-
cally includes EVENTS, REPORTS, SETTINGS, and SYNCHROPHASOR
directories. For FILE READ operations, specify the directory parameters as
needed. The FILE WRITE command is available only for the SETTINGS directory.
