Bus participant device for connection to a line-redundant, serial data bus and method for controlling the communication of a bus participant with a line-redundant, serial data bus

摘要

The device (16,18,20) has a line selection logic, and two bus communication interfaces for connecting with number of lines (12,14) of the data bus (10). The data receiving units (22,24,26,28,30,32) are connected through assigned bus communication interface to associated line of data bus. The data receiving units receive data block from associated line, and forwards received block of data to line selection logic. The logic selects one line of data bus as receiving line and forwards received data block through selected line. The data receiving units are provided with own timer device. An independent claim is included for method for controlling communication of bus device with redundant line serial data bus.
