Abstract

Some of the devices (2-5), connected to the bus (1), have associated bus supplies (10), and determine for themselves whether to supply the bus or not depending on the current flow. A transmitting device determines the current flowing in the bus and switches off its internal current supply to the bus when the detected current exceeds an upper current limit. If the current is below a lower limit, it switches on its supply, if it is not already on. If the current is between the two limits, the internal supply state remains unchanged.
