SEL-700G Relay
Communications
SEL ASCII Protocol and Commands
Access Level 2
When the relay is in Access Level 2, the SEL-700G sends the prompt:
See the SEL-700G Relay Command Summary at the end of this manual for the
commands available from Access Level 2. Any of the Access Level 1
commands are also available in Access Level 2.
Access Level C
The CAL access level is intended for use by the SEL factory, and for use by
SEL field service personnel to help diagnose troublesome installations. A list
of commands at the CAL level is available from SEL upon request. Do not
enter the CAL access level except as directed by SEL. The CAL command
allows the relay to go to Access Level C. Enter the CAL command at the
Access Level 2 prompt:
Command Summary
The SEL-700G Relay Command Summary at the end of this manual lists the
serial port commands alphabetically. Much of the information available from
the serial port commands is also available via the front-panel pushbuttons.
Access Level
Functions
The serial port commands at the different access levels offer varying levels of
control:
➤
The Access Level 0 commands provide the first layer of security.
In addition, Access Level 0 supports several commands
necessary for SEL communications processors.
➤
The Access Level 1 commands are primarily for reviewing
information only (settings, metering, etc.), not changing it.
➤
The Access Level 2 commands are primarily for changing relay
settings.
➤
Access Level C (restricted access level, should be used under
direction of SEL only)
The SEL-700G responds with
Invalid Access Level
when a command is
entered from an access level lower than the specified access level for the
command. The relay responds with
Invalid Command
to commands that are
not available or are entered incorrectly.
Header
Many of the command responses display the following header at the beginning:
Table 7.6 lists the header items and their definitions.
