IRI (IRIG-B Synchronization)
Access Levels 1, B, 2
The
IRI
command forces the relay to read the demodulated IRIG-B time-code input at the time
of the command.
If the relay reads the time code successfully, it updates the internal clock/calendar time and date
to the time-code reading. The relay then transmits a message with relay settings RID and TID,
and the date and time.

If no IRIG-B signal is present or the code cannot be read successfully, the relay sends the error
message “IRIG-B DATA ERROR.”
Note:
Normally, it is not necessary to synchronize using this command because the relay
automatically synchronizes approximately once a minute. The
IRIG
command is
provided to prevent delays during testing and installation checkout.
MET (Metering Report)
Access Levels 1, B, 2
The
MET
command displays currents, voltages, demand currents, peak demand currents, or
differential data, depending on the command statement. There are several choices for the
MET
command, listed briefly below. Refer to
Section 5: Metering and Monitoring
for a complete
description of the metering reports.
MET
Displays winding voltage and current metering data, in
primary amperes
MET D
Displays winding demand ammeter data, in primary amperes
MET DIF
Displays differential current metering data, in multiples of
tap
MET E
Display energy metering data (see
MET E
below)
MET H
Displays harmonic spectrum of currents and voltages (see
MET H
below)
