Basic Relay Operations
Making Simple Settings Changes
The TERSE Option
You can avoid viewing the entire class settings summary the relay displays when
you type END <Enter> midway through a settings class or instance.
On slow data speed links, waiting for the complete settings readback can clog
your automation control system or take too much of your time for a few settings
changes. Eliminate the settings readback by appending TERSE to the SET command.
Text-Edit Mode Line Editing
Some relay settings present multiple input lines to your terminal; you use basic
line text editing commands to construct the setting. For display, the relay refer-
ences each line of the setting by line number, not by the setting name. See Mak-
ing Text-Edit Mode Settings Changes on page 3.22 for an example of a text-edit
mode setting.
While in the text-edit mode, you see a prompt consisting of the line number and
the present setting for that line. You can keep the setting, enter a new setting, or
delete the setting. Table 3.6 lists the commands for text-edit mode.
Use commas to separate the items in a text-edit mode setting when you are enter-
ing multiple items per line. After you enter each line, the relay checks the validity
of the setting. If the entered setting is invalid, the relay responds with an error
message and prompts you again for the setting.
Making Text-Edit Mode Settings Changes
The procedure in the following steps familiarizes you with basic text-edit mode
line editing.
Table 3.6 Actions at Text-Edit Mode Prompts
Action Relay Response
<Enter> Accept the setting and move to the next line; if at the last line or at a
blank line, exit settings.
>n <Enter> Move to line n. If this is beyond the end of the list, move to a blank line
following the last line.
^ <Enter> Move to the previous line; if at the first line, stay at the present line.
< <Enter> Move to the first line.
> <Enter> Move to a blank line following the last line.
LIST <Enter> List all settings and return to the present action prompt.
DELETE [n]
<Enter>
Delete the present line and subsequent lines for a total of n lines; n =1
if not provided. Lines after deletion shift upward by the number of lines
deleted.
INSERT <Enter> Insert a blank line at the present location; the present line and subse-
quent lines shift downward.
END <Enter> Go to the end of the present settings session. Prepare to exit settings via
the
Save settings (Y,N) ? prompt.
<Ctrl+X> Abort editing session without saving changes.
NOTE: To begin an entry with one of
these keywords, especially in notes
settings, put the string in quotes: e.g.
"END OF REPORT".
