Figure 62: IEC 61850: Horizontal communication principle
Figure 62 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 engineered 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.
If the quality of the value is needed in the receiver IED, the quality must be included in the
GOOSE data set. The receiver side will connect this automatically and if the quality is not in the
data set, a warning message will occur in PCM.
7.1.3 Station configuration description file types
SEMOD58549-93 v5
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.
• ICD = IED Capability Description
The IED name in an exported .icd file is always named TEMPLATE.
• Capability description of the IED in logical nodes and their data. No information
about communication configuration, for example, is included.
• An IED is already extended by default data sets. They are predefined by ABB.
Changes or additional data sets, for example, have to be done with the IET600
station configuration tool.
• SCD = Station Configuration Description
