Command Description
MAP
Use the MAP command to view the organization of the relay database. The MAP
command in the relay is very similar to the MAP command in the SEL-2020 and
SEL-2030 Communications Processors.
MAP 1
The MAP 1 command lists the relay database regions. Typical database region
names are LOCAL, METER, DEMAND, TARGET, HISTORY, BREAKER,
STATUS, and ANALOGS.
MAP 1 region and MAP 1 region BL
Use the MAP 1 command with the region option to view the layout of a specific
region.
The region option is the database region name shown in the simple MAP 1 com-
mand response. The region map consists of columns for data item labels, data-
base 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. The TARGET region is usually the only region containing bit labels.
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).
All SEL-400 series relays support a METER command, but the options and
responses are device specific. See the product-specific instruction manual for
details of the METER command. Included below are the variants of the
METER command that are common.
