ASCII Command Reference
Description of Commands
CAL
Use the CAL command to gain access to Access Level C. See Access Levels
on page U.4.6 for more information. Only go to Level C to modify the default
password or under the direction of an SEL employee. The additional
commands available at Level C are not intended for normal operational
purposes.
CASCII
The CAS command produces the Compressed ASCII configuration message.
This configuration instructs an external computer on the method for extracting
data from other Compressed ASCII commands. See Section 5: SEL
Communications Protocols for an example of the CAS command
configuration message and for further information on the Compressed ASCII
command set.
CBREAKER
The CBREAKER command provides a Compressed ASCII response circuit
breaker report that is similar to the BREAKER command. You must enable
the Breaker Monitor function for either Circuit Breaker 1 or Circuit Breaker 2
to generate the Compressed ASCII report. You can specify Circuit Breaker 1
or Circuit Breaker 2 to retrieve a report for one circuit breaker only. See
Section 5: SEL Communications Protocols for information on the Compressed
ASCII command set.
CBR
Use the CBR command to gather the comprehensive circuit breaker report in
Compressed ASCII format. For a detailed example, see Section 2: Monitoring
and Metering in the Applications Handbook.
