7-24 Communications Date Code 20080110
SEL-387E Instruction Manual
• DEVID: reports the device identification (DID setting)
• DEVCODE: reports the Modbus
®
device code
• CONFIG: reports the device configuration (e.g., nominal current and nominal frequency)
INI (Initialize Interface Board)
Access Levels 1, B, 2
The INI command reports the number and type of interface boards in the relay from Access
Levels 1 and B. If the number or type of interface boards has changed since last power up, INI
will confirm from Access Level 2 that the interface boards present are correct.

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.
=>IRI <Enter>
XFMR 1 Date: MM/DD/YY Time: HH:MM:SS.SSS
STATION A
=>
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.
