ASCII Command Reference
Description of Commands
the output; if the output is closed, the PUL command momentarily opens the
output. The control outputs are OUTnnn, where nnn represents the 100-
series, 200-series, and 300-series addresses.
If the circuit breaker control enable jumper BREAKER is not in place, the
relay aborts the command and responds,
Aborted: the breaker jumper is
not installed
.
When you issue the PUL command and the breaker jumper is in place, the
relay responds,
Pulse contact OUTnnn for s seconds (Y/N)? If you
answer Y <Enter>, the relay asserts OUTnnn for the time you specify.
During the PUL operation, the Relay Word bit corresponding to the control
output you specified (OUTnnn) asserts; Relay Word bit TESTPUL asserts also
during any PUL command, so you can monitor pulse operation by
programming TESTPUL into event triggers and alarm outputs.
QUIT
Use the QUIT command to revert to Access Level 0 (exit relay control).
Access Level 0 is the lowest access level; the relay performs no password
check to descend to this level (or remain at this level).
In a Telnet session, QUIT terminates the connection.
RTC
Use the RTC command to display a description of all data being received on
synchrophasor client channels. This report will list the analog quantity and
Relay Word bits the data gets stored in locally, matched up with a label
provided by the sending PMU. Use this information as aid to understanding
the local values.
SER
The SER command retrieves SER (Sequential Events Recorder) records. The
relay SER captures state changes of Relay Word bit elements and relay
conditions. Relay conditions include power up, relay enable/disable, group
changes, settings changes, memory queue overflow, and SER autoremoval/
reinsertion. For more information on the Sequential Events Recorder, see
Section 8: Oscillography, Events, and SER.
