SEL-400 Series Relays Instruction Manual Date Code 20171006
ASCII Command Reference
Command Description
VIEW 1 Commands—Bit
Use commands in Table 14.145 to inspect a specific bit in the relay database. The
relay displays bit data as the bit label or number and the value logical 1 or logical
0. An example of a relay response for bit commands is
1:TARGET:ALTI = 0,
where
ALTI is the bit label and 0 is the bit value.
The command option bit is the bit number. If you access bit data, the relay dis-
plays the bit label or number and the value (logical 0 or logical 1). If you refer-
ence 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 struc-
ture 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.
