SEL-2701 Ethernet Processor Instruction Manual Date Code 20020501
Introduction
Applications
File Exchange
Use the SEL-2701 to exchange files with SEL hosts across an Ethernet
network. The SEL-2701 provides FTP access to files in the SEL host. You can
use a PC to collect event reports, sequential events recorder (SER) reports,
settings, and snapshots of metering data.
As with Telnet, there are free FTP applications included with several
operating systems and web browsers. Start the FTP application, log in, and use
point and click operations to exchange files with SEL hosts.
UCA2 Networking
Use the SEL-2701 to provide UCA2 connectivity to SEL hosts including the
SEL-2030 and SEL-400 series relays. Data in the host are presented in
GOMSFE models. In an SEL-400 series relay, the SEL-2701 automatically
populates GOMSFE models with relay measurements and other data. For
IEDs connected to the SEL-2030, you must configure the SEL-2030 to collect
data. Then the SEL-2701 automatically populates GOMSFE models with the
available data.
GOOSE peer-to-peer messaging is part of the GOMSFE model called
GLOBE. GOOSE is used for peer-to-peer control and protection messages.
The SEL-2701 generates outgoing GOOSE messages based on information in
the host. The SEL-2701 also monitors incoming GOOSE messages and passes
selected information to the host. If your host is an SEL-2030, the GOOSE
messages can be used to transmit information from and pass controls to the
connected IEDs.
Application
Examples
Networking for Installed SEL Relays Without Card Slots
By adding an SEL-2701 installed in an SEL-2030 to your design or adding an
SEL-2701 to your existing SEL-2030 as shown in Figure 1.3 on page 1.7, you
can quickly and inexpensively gain the advantages of Ethernet and UCA2
network connectivity:
➤ Use Telnet for engineering connections to the SEL-2030 and
connected relays.
➤ Use FTP to collect snapshots of data regions in the SEL-2030
with FTP file exchange.
➤ Use UCA2 master devices to collect data from the SEL-2030
and connected relays.
➤ Use GOOSE to exchange control data between relays
connected to the SEL-2030 and other UCA2 IEDs.
