Sel SEL-421 - IEC 61850 Communications

Date Code 20111215 Reference Manual SEL-421 Relay
Section 8
R.Reference Manual
IEC 61850 Communications
Features
The SEL-421 Relay supports the following features using Ethernet and
IEC 61850:
➤ SCADA—Connect up to six simultaneous Ethernet client
sessions. The SEL-421 also supports up to six buffered and six
unbuffered report control blocks.
➤ Real-Time Status and Control—Use GOOSE with as many
as 24 incoming (receive) and 8 outgoing (transmit) messages.
NOTE: The SEL-421 supports one CID
file, which should be transferred only
if a change in the relay configuration
is required. If an invalid CID file is
transferred, the relay will no longer
have a valid IEC 61850 configuration,
and the protocol will stop operating.
To restart protocol operation, a valid
CID must be transferred to the relay.
➤ Configuration—Use FTP client software or ACSELERATOR
Architect
®
SEL-5032 Software to transfer the Substation
Configuration Language (SCL) Configured IED Description
(CID) file to the relay.
➤ Commissioning and Troubleshooting—Use software such as
MMS Object Explorer and AX-S4 MMS from Sisco, Inc., to
browse the relay logical nodes and verify functionality.
➤ Firmware Upgrades—Use FTP client software to transfer the
Ethernet port firmware upgrade file to the relay.
