Abstract: A communication method between subscribers of a network having multiple components of a mechatronic system, wherein payload data are communicated between the subscribers via the network by messages, and payload data of multiple subscribers are combined in a sum frame message and the sum frame message is sent to the subscribers. To use network resources more efficiently, a configurable routing structure is used to route the messages, said routing structure containing at least one partial route, and at least one partial message pertaining to this partial route is composed that, as a sum frame partial message, contains just payload data from subscribers of this partial route, the sum frame partial message is routed via this partial route and subscribers of the partial route can each extract their payload data from the sum frame partial message and/or write said payload data to the sum frame partial message.
