Data Access Settings
Access data using either the standard TCP/IP Telnet and FTP interfaces or
through the UCA2 interface. You cannot access all data through all interfaces.
Please see the appropriate interface section below for details on data access.
FTP
FTP is a standard application-level protocol for exchanging files between
computers over a TCP/IP network. The SEL-2701 operates as an FTP server.
It presents SEL-2701 and host files to FTP clients. The SEL-2701 can support
as many as three simultaneous FTP sessions, allowing simultaneous FTP
access to as many as three separate users.
The host maintains the access control list that determines FTP log-in IDs and
passwords. The host also determines which files are available. Some files are
available at specific log-in levels, while other files are read-only access.
Subsequent host-specific sections describe access control for each host.
File Structure
The basic file structure common to all hosts is organized as a directory and
subdirectory tree similar to that used by Unix, DOS, Windows, and other
operating systems. The root directory is “/” and has at least one subdirectory.
The basic file structure is shown in
The first subdirectory is for the host. Some hosts do not have a subdirectory.
The HOST_ID string, if set, determines this subdirectory name. The
SEL-2701 strips any leading or following white-space characters. The
SEL-2701 then substitutes the “_” character for any white-space or delimiter
characters. For example, if the HOST_ID is IED#983 Sub#45, then the host
subdirectory name is IED_983_Sub_45. If the converted HOST_ID is longer
than 31 characters, the host subdirectory name becomes the first 31 characters
of the converted HOST_ID. The host subdirectory contains settings, reports,
and diagnostic files for the host.
The next subdirectory is SEL-2701. This subdirectory contains the file
DIAGNOSTICS.TXT that contains records for SEL-2701 system failures.
The time and date for the diagnostics file are the same as the time and date of
the last system failure event.
The SEL-2701 creates a subdirectory for each virtual device in the host. The
subdirectory name is DDnn_substring, where nn is the virtual device number
