shows the GOOSE concept for three IEDs which interchange GOOSE messages
between each other.
To send GOOSE messages a GoCB must be defined and a data set is needed that contains
the data objects of single data attributes to be sent.
A GOOSE message is forced to be transmitted when a trigger change is detected for a data
attribute. All members of the data set are copied in the send buffer with their actual value
and the message is sent. The subscribers, who knows the address of this GOOSE message,
receives the telegram. The GOOSE message includes a sequence number to verify that all
messages are received.
