ASCII Command Reference
Description of Commands
The region option is the database region name shown in the simple MAP 1
command response. The region map consists of columns for data item labels,
database address, and data type.
If you specify the BL option and the region contains items with bit labels, the
relay lists these bit labels in MSB (most significant bit) to LSB (least
significant bit) order. Examples of database bit label names are M1P,
25W1BK2, and ASV256.
METER
The METER command displays reports about quantities the relay measures
in the power system (voltages, currents, frequency, remote analogs, and so on)
and internal relay operating quantities (math variables and synchronism-check
values). For more information on power system measurements, see Section 2:
Monitoring and Metering in the Applications Handbook. For information on
math variables, see Section 3: SEL
OGIC Control Equation Programming. Find
a discussion of synchronism check in Section 2: Auto-Reclosing and
Synchronism Check.
LINE, BK1, and BK2 command options generally measure feeder lines
parameters and circuit breaker currents, depending on relay configuration (see
Current and Voltage Source Selection on page R.1.2).
MET
Use the MET command to view fundamental metering quantities. The relay
filters harmonics and subharmonics to present only measured quantities at the
power system fundamental operating frequency.
The MET command without options defaults to the LINE fundamental
metering data. Specify Circuit Breaker 1 and Circuit Breaker 2 by using the
BK1 and BK2 command options, respectively.
Some situations require that you repeatedly monitor the power system for a
brief period; specify a number after any MET command to automatically
repeat the command.
