Method for operating a slave node of a digital bus system

摘要

A method for operating a slave node of a digital bus system is described. The slave node comprises two sending and receiving devices. In the bus system, an input data frame is sent to a master node in input direction. The slave node receives the input data frame by the first sending and receiving device. The slave node stores service data packets contained in the input data frame in a FIFO memory. The slave node attaches at least one process data packet of its own to a last process data packet in the input data frame. The slave node attaches the service data packets to the process data packet, which is now last, in the input data frame. The slave node sends the input data frame, which was changed in this manner, to the next node in input direction by the second sending and receiving device.

1. A method for operating a slave node of a digital bus system, wherein the slave node is configured to operate a high-power semiconductor switching element, wherein the slave node comprises a first sending and receiving device and a second sending and receiving device, wherein an input data frame is sent to a master node in the bus system in an input direction, the method comprising:
receiving the input data frame by the first sending and receiving device; storing service data packets contained in the input data frame in a FIFO memory; attaching at least one process data packet of the slave node to a last process data packet in the input data frame; attaching the service data packets stored in the FIFO memory to the last process data packet in the input data frame; and sending the input data frame comprising the last process data packet to a next node in the input direction by the second sending and receiving device.
