Network Connection and Integration
Figure 16 Network Connection and Integration
Connect the SEL-487V to Local Area Networks (LANs)
using the Ethernet option. The Ethernet option allows
connection of the SEL-487V to a single or dual LAN
(see Figure 18). The integrated Ethernet card supports
both copper or fiber connections with fail-over
protection.
Ethernet
Telnet applications allow simple terminal
communications with SEL relays and other devices.
Transfer data at high speeds (10 Mbps or 100 Mbps) for
fast HMI updates and file uploads. Ethernet
communications use File Transfer Protocol (FTP)
applications for easy and fast file transfers.
Provide operations with situational awareness of the
power system using IEEE C37.118-2005 Standard for
Synchrophasors for Power Systems. Communicate with
SCADA and other substation IEDs using DNP3 or
IEC 61850 logical nodes and GOOSE messaging.
Choose Ethernet connection media options for primary
and standby connections:
➤ 10/100BASE-T twisted pair network
➤ 100BASE FX fiber-optic network
Telnet and FTP
Order the SEL-487V with Ethernet communications and
built-in Telnet and File Transfer Protocol (FTP) that
come standard with Ethernet to enhance relay
communication sessions. Telnet can access relay
settings, as well as metering and event reports remotely
using the ASCII interface. Transfer settings files to and
from the relay via the high-speed Ethernet port with FTP.
IEEE C37.118 Synchrophasors
The latest IEEE synchrophasor protocol provides a
standard method for communicating synchronized
phasor measurement data over Ethernet or serial media.
The integrated Ethernet card in the SEL-487V provides
two independent connections using either TCP/IP,
UDP/IP, or a combination thereof. Each connection
supports unicast data for serving data to a single client.
Each data stream can support up to 60 frames per second.
DNP3 LAN/WAN
The DNP3 LAN/WAN option provides the SEL-487V
with DNP3 Level 2 server functionality over Ethernet.
Custom DNP3 data maps can be configured for use with
specific DNP3 masters.
HTTP Web Server
When equipped with Ethernet communication, the relay
can serve read-only web pages displaying certain set-
tings, metering, and status reports. As many as four users
can access the embedded HTTP server simultaneously.
