While SubSubEvent-IDs are equal to the network address of the corresponding board by design, the SubEvent-IDs can be choosen freely, but are defined to be equal to the network address of the board sending the SubEvent via Gigabit Ethernet. The first digit of each SubSubEvent-ID is sufficient to determine how the following data has to be handled: -- 2.43.0
