Assignee: ROBERT BOSCH GMBH
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 9:
10. A user station for a serial bus system, comprising:
a communication control device configured to control a communication of the user station with at least one other user station of the bus system; and
a transceiver device configured to serially transmit a transmission signal, generated by the communication control device, onto a bus of the bus system, and configured to serially receive signals from the bus of the bus system;
wherein the communication control device is configured to generate the transmission signal according to a frame and to insert a header check sum into the frame, only bits of a frame header that is situated in front of a data field provided for useful data in the frame being included in a computation of the header check sum, the communication control device being configured to insert dynamic stuff bits into the frame header in such a way that an inverse stuff bit is inserted into the bit stream of the frame after 5 identical bits in succession, and for computing the header check sum, the communication control device is configured to use at least one switching element of an electrical circuit which is settable to a predetermined starting value, a predetermined check sum polynomial being implemented by the switching element or the electrical circuit, the predetermined check sum polynomial being equal to x13+x12+x11+x8+x7+x6+x5+x2+x1+1.
