SEL-387E Instruction Manual
If a warning or failure state occurs, the next time the
STA
command is issued, the warning state
is reported. If a warning or failure occurs, it will not be cleared until relay power is cycled and
the problem is fixed. Saving relay settings also warm boots relay logic. This may clear some
warnings, but do not ignore warnings; contact the factory.
The
STA C<ENTER>
command also clears any out-of-tolerance condition from the status
report and reboots the relay. Do not ignore the warning; contact the factory.
If the Analog Input Label settings (IAW1, etc.) have been renamed, these will appear in the
report as set. For the STA report format see the example following
Status Reporting Function
in
Section 5: Metering and Monitoring

TAR (Show Relay Word Targets On Screen)
Access Levels 1, B, 2
The
TAR
command displays the default row of the Relay Word showing the Relay Word bit
names and their value, which is either a logical 1 (asserted) or logical 0 (deasserted). The syntax
of the
TAR
command follows:
TAR n k X<ENTER>
n
specifies a new default Relay Word row by entering the row number or the specific
Relay Word bit name (except names of target elements in rows 0 and 1). If n is
not specified, the last default row is displayed.
k
specifies a repeat count for the command. The default is 1.
X
allows viewing a Relay Word row without changing the default row.
The default row number can also be changed by the
TAR F
command, but each serial port has
independent defaults. The default row number returns to 0 when the port times out, the
QUI
command is executed,
TAR 0
command is executed, or the
TAR R
command is executed.
The
TAR
command does not remap the front-panel LEDs. See the
TAR F
command.
The following examples demonstrate the
TAR
command:
