The sending data set is defined with the GOOSE control block. A maximum of 120 data attributes can be added to the IED's GOOSE data sets. The recommendation is to divide the attribute amount to 20 per GOOSE data set, for maximum performance in sender and receiver.
All data sets must be configured under the logical node LLN0 and must be provided with unique names in the relay. For more information on GOOSE data sets, see Table 2. In simple GOOSE applications it is often sufficient to define a single data set and control block for an application. However, it is recommended to use a separate data set and corresponding control block for analog values.

To add a new data set, right-click the area containing the data set names and select New.
Figure 2. Creating a new data set -
Define the LN where the data set is to be placed (accept preselected “ LD0/ LLN0”) and give the data set a unique name.
Figure 3. Naming the data set
After creating the GOOSE data sets, define the data set entries (data attributes or data objects) for the data sets.
The received GOOSE data set can contain signals on the data attribute or data object level. However, it is strongly recommended that GOOSE data sets be made on the data attribute level for faster data processing.
