Command Description
HELP
The HELP command gives a list of commands available at the present access
level. You can also get a description of any particular command; type HELP fol-
lowed by the name of the command for help on each command.
HISTORY
The HISTORY command displays a quick synopsis of the last 100 events that
the relay has captured. The rows in the HISTORY report typically contains the
event serial number, date, time, location, maximum current, active group, and tar-
gets. (The specific content depends on the relay.) See Section 9: Reporting and
Section 7: Metering, Monitoring and Reporting in the product-specific instruc-
tion manual for more information on history reports.
HIS
Use the HIS command to list one-line descriptions of relay events. You can list
event histories by number or by date.
HIS C and HIS R
The HIS C and HIS R commands clear/reset the history data and corresponding
high-resolution/event report data on the present port. Options C and R are identical.
The relay prompts you with Are you sure (Y/N)? when you issue the HIS C
and HIS R commands. If you answer Y <Enter>, the relay clears the present port
history data.
