Data Access
Data Access
FTP
You can access the file structure and contents described in Table 5.5 after
logging in to the SEL-2701 as an FTP client. Files named for database regions
contain the most current values at the time you request the files. You can write
files to the SEL-400 series relay only if you are logged in at the appropriate
level. See your relay instruction manual for more information on files in the
SEL-400 series relays. Files associated with the SEL-2701 are in the
SEL-2701 directory, as described in
Section 3: Settings and Commands .
Telnet
You can establish two types of Telnet connections with the relay and the
SEL-2701.
Telnet to the Relay
For the first connection type, use the TCP/IP host port number (see setting
T1PNUM in
Table 3.6 on page 3.7 in Section 3: Settings and Commands ) to
Telnet to the relay. This connection emulates the capabilities of a connection
to the relay front port. All relay commands are available, including access
level commands. Use the
QUIT command to log out and end the Telnet
session.
Telnet to the SEL-2701
For the second connection type, use the SEL-2701 TCP/IP port number (see
setting T2PNUM in
Table 3.6 on page 3.7 in Section 3: Settings and
Commands ) to Telnet directly to the SEL-2701. This is useful for operating
the SEL-2701 user interface to collect diagnostic data and perform other
operations with the SEL-2701. Use the QUIT command to log out and end the
Telnet session.
UCA2
The SEL-2701 installed directly in an SEL-400 series relay provides a high
performance UCA2 network interface that is designed for operation in a
substation environment.
