Abstract
The network including functional nodes (10) connected in series by a data transmitter (11; 12), in which the data assumes the form of discrete messages propagating from node to node in the network, is characterized in that the a data transmitter (11; 12) between the nodes are bidirectional to allow data to propagate in both circulation directions of the network, and each node (10) includes at least one first and one second port associated by programming, for data input/output (13, 14), connected to adjacent nodes by a corresponding data transmitter (11; 12) and the operation of which is controlled exclusively and sequentially, by a communication automaton (15), between an operating mode for the asynchronous reception of data from the adjacent nodes, and an operating mode for the synchronous transmission of data to the nodes adjacent thereto.

22. A data transmission network comprising:
-
functional nodes connected in series by at least one data transmitter, the data assuming the form of discrete messages propagating from node to node in the network; the at least one transmitter for transmitting data between the nodes being bidirectional to allow data to propagate in both circulation directions of the network, each node including at least one first and one second port associated by programming, for data input/output, connected to adjacent nodes by a corresponding data transmitter of the at least one transmitter and the operation of each node is controlled exclusively and sequentially, by a communication automaton, between an operating mode for the asynchronous reception of data from the adjacent nodes, and an operating mode for the synchronous transmission of data to the nodes adjacent thereto. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)
