Network node in a ring bus and method for operating it connects to a bus with first and second inputs and first and second outputs while linked to a network microcomputer.

摘要

Network node (K0) connects to bus (B) with first (K0E1) and second (K0E2) inputs and first (K0A1) and second (K0A2) outputs and is provided with network microcomputer. First detector fits on first input of network node in signal path. First switch unit between first input and output of network node connects or disconnects node's second output and first input when reacting to control signals from first detector.
