SEL ASCII Protocol and Commands
GROUP Command
Use the GROUP command (see Table 7.23) to display the active settings
group or try to force an active settings group change.
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–SS3 are set when you issue the
GROUP n command, the group change will fail. The relay responds:
Command
Unavailable: Active setting group
SEL
OGIC
equations have
priority over the GROUP command
.
HELP Command
The HELP command (see Table 7.24) 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.
HISTORY Command
Use the HIS command (see Table 7.25) to view a list of one-line descriptions
of relay events or clear the list (and corresponding event reports) from
nonvolatile memory. For more information on event reports, see Section 9:
