Figure 61: IEC 61850: Horizontal communication principle
Figure 61 shows an example with three IEDs where each one communicates with all
the others.
When a GOOSE message is to be sent is defined by configuring the data set with the
defined trigger option and the GOOSE control block (GoCB). This engineering process
is done in the IET600 station configuration tool. The task involves configuring lists
with the signal, value and quality (data attributes) that belong to the GOOSE message
dataset.
In the opposite direction the standard only defines the IED as a receiver of the GOOSE
message. How the GOOSE input signals are handled must be defined in the IED
application configuration. The SCD file generated by the IET600 station configuration
tool contains these GOOSE data sets as input data. The input data must be connected to
a GOOSE receive function block (GOOSEBINRCV, GOOSEINTLKRCV,
GOOSESPRCV, GOOSEDPRCV, GOOSEINTRCV or GOOSEMVRCV) in SMT.
7.1.3 Station configuration description file types
The IEC 61850 standard defines SCL-file types in the sequence of engineering. These
files have a different definition, which is explained in IEC 61850–6. Three of these file
types are used in the engineering process for an IED.
