A subscriber
station (10; 30) for a serial
bus system (1) and a method for communication in a serial
bus system (1) are provided. The subscriber
station (10, 30) has a
communication control device (11, 31) for controlling communication of the subscriber
station (10, 30) with at least one other subscriber station (10, 20, 30) of the
bus system (1), and a transmitting / receiving device (12; 32), which is designed to transmit data to the
communication control device (11; 31) to a bus (40) of the bus system (1), and which is designed to serially receive signals from the bus (40) of the bus system (1), the
communication control device (11; 31) is designed to generate a transmission
signal (TXD) in accordance with a frame (450) and to insert a header
checksum (HCRC) into the frame (450), in which only bits of a frame header located prior to a
data field (455) set for valid data in the frame (450) are included, 31) is designed in such a way that the communication control device (11; 31) is designed to use, for the calculation of the header
checksum (HCRC), a predetermined start value (RS) and a predetermined
checksum polynomial (CRCP), in which case the intermediate result of the calculation of the header checksum (HCRC) for the portion of the frame header in which the dynamic padding bits are used is not equal to a zero vector.
