SEL-421 Relay Reference Manual Date Code 20111215
ASCII Command Reference
Description of Commands
The command option bit is the bit number. If you access bit data, the relay
displays the bit label or number and the value (logical 0 or logical 1). If you
reference the data by label with the BL and bit_label options, the relay returns
the data according to the data type.
Use the VIEW 1 bit_label command as a shorthand method to inspect a
specific data bit in the relay database. The relay searches the entire relay
database structure for the bit label you specified; this process takes more time
and processing than narrowing the search by using the VIEW 1 region
command and the VIEW 1 addr command with the bit label option bit_label.
