Figure 9.3 Sample VER Command Response
If an item is not installed, the VER report indicates Not installed at the
appropriate line. If a detected hardware configuration does not match the
component part number, the relay adds the statement
Warning - hardware
does not match part number
on the corresponding line.
VIEW
Use the VIEW command to examine data within the relay database. You can
view these data in three ways:
➤ Region
➤ Register item
➤ Bit
The VIEW command in the SEL-421 is very similar to the VIEW command
in SEL Communications Processors. See Section 4: Communications
Interfaces for more information on the relay database regions and data types.
SEL-421 regions are LOCAL, METER, DEMAND, TARGET, HISTORY,
BREAKER, STATUS, and ANALOGS; view this list with the MAP 1
command.
The SEL-421 is Virtual Device 1; all commands begin VIEW 1. In all
database views, if a data item is in test mode, the relay displays an asterisk (*)
mark following the data value.
