Abstract

A process for the localization of defective stations in local networks which consist of several locally distributedly operating stations is proposed, particularly for use in automobiles. The process is characterized by station-internal, statistical evaluation of external and/or internal error signals. The redundancy necessary for a self-monitoring of the stations interconnected by a serial bus need not be available locally in the respective station, rather only the redundancy existing in any case in a network due to the presence of protocol-compatible stations is utilized.
