7.2 IEC 61850 PROFILE FOR W650
7.2IEC 61850 PROFILE FOR W650
IEC61850 is a series of standards describing client/server and peer-to-peer communications, substation design and
configuration, testing environmental and project standards.
The W650 relay supports IEC61850 server services over TCP/IP. This profile requires the W650 to have an IP address to
establish communications. It is possible to have up to five simultaneous connections.
A built-in TCP/IP connection timeout of two minutes is employed by the W650 to detect "dead" connections. If there is no
data traffic on a TCP connection for greater than two minutes, the connection will be aborted by the server. Therefore, when
using IEC61850 reporting, clients should configure report control block items such that an integrity report will be issued al
least every 2 minutes. If other MMS data is being polled on the same connection al least once every 2 minutes, this timeout
will not apply.
The exact structure and values of the supported IEC61850 logical nodes can be seen by connecting to a W650 relay with
an MMS browser, such as "MMS Object Explorer and AXS4-MMS" DDE/OPC server from Sisco Inc.
Peer-to-peer communication of a digital state information ( remote inputs/outputs ) is supported using the IEC61850 GSSE
services. This feature allows digital points to be exchanged between IEC 61850 conforming devices.
MMS file services are supported to allow transfer of oscillography, event record, or other files from a W650 relay.
