Bus system and method for allocating addresses of bus nodes in a bus system

Abstract

The invention relates to a control node (3) for a bus system (1), wherein the control node (3) is adapted to control a number of devices (6); comprising: a control unit (31) configured to send an address-request-signal as soon as supply power is applied onto the control node (3) via at least one power supply line (7) at a first or second power supply terminal (33, 34) and to receive an address-allocation-signal including a unique address via at least one data line (8); a switching unit (32) which is configured to electrically interconnect the first and second power supply terminal (33, 34) immediately and directly after control unit detects that the address-allocation-signal has been received.
