Patent ID: 8855216

Claim:
A method for supplying at least one bus user via a control unit, the method comprising: transmitting data to the at least one bus user during at least one phase for data transmission; and transmitting power during at least one phase for power transmission, the at least one phase for data transmission and the at least one phase for power transmission being provided alternately; wherein at least one of a length of the phase for data transmission and a length of the phase for power transmission is set variably, wherein a control unit having a dynamic interface is used to switch over between the at least one phase for power transmission and the at least one phase for data transmission, and wherein at least one of the length of the phase for data transmission and the length of the phase for power transmission are at least one of flexibly adapted and dynamically adapted to at least one of a quantity of the data to be transmitted and to a demand for power of the at least one bus user, wherein power is provided at a first high output during the at least one phase for power transmission, and wherein power is provided at a second, lower output, in addition to the data, during the at least one phase for data transmission.
