Abstract (en)

[origin: WO03104036A1] Disclosed are a method for switching a serially linked system (100), particularly a serial data bus system, from subnetwork operation (T) in which at least one node (22, 28) and/or at least one user (32, 38) of the system (100) is/are in a state of reduced energy consumption and is/are not addressed and/or activated by the signal levels (40, 42, 44) of the data communication in the system (100), to full network operation (G) in which all nodes (20, 22, 24, 26, 28) and/or all users (30, 32, 34, 36, 38) of the system (100) are addressed and/or activated by the signal levels (46, 48) of the data communication in the system (100), and a corresponding system (100). In order to further develop said method and system (100) in such a way that the nodes (22, 28) and/or users (32, 38) of the network, i.e. on the data bus (10), can be awakened in a simple and effective manner, the system (100) is switched from subnetwork operation (T) to full network operation (G) when a zero signal level (50) and/or no modification of the signal level is detected in the system (100) for a period of time (<t) which is greater than a predefined or adjustable critical period of time (?tk).
