The sending data set is defined with the GOOSE control block. With the IEDs of this product series, the sending GOOSE data set can have a maximum of 20 data attributes to minimize the message-handling load in the receiving and sending IEDs.
All data sets must be configured under the logical node LLN0 and must be provided with names unique within the IED. The IEDs allow a maximum of four GOOSE control blocks, which effectively limits the IED to four data sets for GOOSE, as there is a one-to-one correspondence between the GOOSE control blocks and GOOSE data sets. Typically, it is 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.
