SEL-421 Relay Reference Manual Date Code 20111215
ASCII Command Reference
Description of Commands
All text enclosed in [brackets] indicate optional command line parameters.
The FILE command allows access to second level subdirectories as the
optional directory2 parameter.
File directories in the SEL-421 are the EVENTS directory, the REPORTS
directory, and the SETTINGS directory. For FILE READ operations, specify
the directory1 (and directory2) parameters as needed. The FILE WRITE
command is available only for the SETTINGS directory and its second level
subdirectories.
GROUP
Use the GROUP command to view the present group number or to change the
active group.
When you change the active group, the relay responds with a confirmation
prompt:
Are you sure (Y/N)? Answer Y <Enter> to change the active
group. The relay asserts the Relay Word bit SALARM for one second when
you change the active group.
If any of the SEL
OGIC control equations SS1–SS6 are set when you issue the
GROUP n command, the group change will fail. The relay responds
No
group change:
SELogic equations SS1-SS6 have priority over GROUP
command
. For information on SELOGIC control equations SS1 through SS6,
see Multiple Setting Groups on page R.3.8.
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
followed by the name of the command for help on each command. For
information about access levels and passwords, see Access Levels on
page U.4.6.
