The concept is based on sending a multicast over Ethernet. The receiver detects the
telegram by its multicast destination address and application identifier, and decodes
the telegram for further processing by the application.

When a GOOSE message is sent, it is defined by configuring the data set with the
defined trigger option and GoCB. This engineering process is done in a station
configuration tool, for example, IEC 61850 Configuration tool or IET600. The task
involves configuring lists with the signal, value and quality (data attributes or data
objects) that belong to the GOOSE message data set.
In the opposite direction, the standard only defines the IED as a receiver of a GOOSE
message. How the GOOSE input signals are handled must be defined in the device's
application configuration. The SCL data generated by the IEC 61850 Configuration
tool or IET600 (or any other station configuration tool) contains the GOOSE data sets
as input data. The input data must be connected to a GOOSE receive function block
in Signal Matrix.

Function view for IEC 61850 in PCM600

The IED design is directly based on IEC 61850. Thus, the function blocks in PCM600
use IEC 61850 logical node naming for function blocks. This relation is automatically
handled by the PCM600 tools.
In the IED, the IEC 61850 data for each function instance is available in the data
model, even when the function is not used in the application. This means that it is not
necessary to handle any instance information for the functions regarding IEC 61850.
