Signal Engineering
Signal engineering consists of DataSets, Report Control Blocks (RCB), and Goose Control Blocks
(GoCB).
DataSets
IEC 61850 has defined DataSets for signal transmission in Report Control Blocks. DataSets are also used
for GOOSE messages. Figure 12 shows a DataSet where all position information of the apparatuses of a
bay are put into one DataSet.
Figure 12. DataSet Example
General rules for DataSet configuration:
•
All data objects or their data attributes can be selected for a DataSet.
•
Only those data attributes of a data object are selected which have the same functional constraint
(FC).
•
Data objects with different FC can be selected for a DataSet. For example DOs with FC=ST and
DOs with FC=MX can be members in one DataSet.
•
A single data attribute can be selected when it is specified with a trigger option. For example the
data attribute stVal of the data object Pos can be selected as a member of a DataSet, because it
is specified with the trigger option data change detected (dchg).
The description of the DataSets and the list of data object members or FCDAs (Functionally Constrained
Data Attributes) is included in the SCL file in the IED section in the Logical Device subsection. FCDAs are
