869 MOTOR PROTECTION SYSTEM – COMMUNICATIONS GUIDE

IEC 61850

The optional communications processor supports both the IEC61850 GOOSE and IEC
61850 MMS Server service as per IEC 61850 standard Ed. 2. The GOOSE messaging service
provides the 869 unit the ability to Publish/Subscribe Digital Input Status and its Quality
and Timestamp to/from other IEDs with supporting GOOSE messaging service, while the
server support allows remote control center, RTU/Gateway, local HMI or other client role
devices access to the relay for monitoring and control. The configuration of IEC61850
services is accomplished using the 869 configuration software, EnerVista 8 Series
Setup software. A rebooting MUST be done before any changes made take affect.
IEC61850 SERVER
The IEC 61850 Server (i.e., 869 relay) reports data to the IEC 61850 Client, such as Local
HMI, RTU and Gateway with the information of logical device, data sets, data control block,
logical nodes and their data attributes.
The following tables list the logical nodes and number of instances for each of the LNs that
are supported within the 869 relay.
