M13912-3 v4
IEC 61850-8-1 communication protocol allows vertical communication to HSI clients and allows
horizontal communication between two or more intelligent electronic devices (IEDs) from one
or several vendors to exchange information and to use it in the performance of their functions
and for correct co-operation.
GOOSE (Generic Object Oriented Substation Event), which is a part of IEC 61850–8–1 standard,
allows the IEDs to communicate state and control information amongst themselves, using a
publish-subscribe mechanism. That is, upon detecting an event, the IED(s) use a multi-cast
transmission to notify those devices that have registered to receive the data. An IED can, by
publishing a GOOSE message, report its status. It can also request a control action to be
directed at any device in the network.

shows the topology of an IEC 61850–8–1 configuration. IEC 61850–8–1 specifies only
the interface to the substation LAN. The LAN itself is left to the system integrator.
