Method for testing of safety of transmission paths within technical device, involves determining safety relevance of transmission paths on which outgoing signal is transferred based on safety relevance data of assigned outgoing signal

摘要

#CMT# #/CMT# The method involves examining the safety relevance of outgoing signals of technical function units (11-13) and storing safety relevance data for outgoing signals. The transmission paths (U11-U13) on which the outgoing signal is transferred are identified, and the outgoing signal is assigned to the identified transmission paths. The safety relevance of the identified transmission paths is determined based on the stored safety relevance data corresponding to assigned outgoing signal. The safety of the identified transmission path is tested based on the determined safety relevance. #CMT# : #/CMT# An independent claim is included for device for testing of safety of transmission paths within technical device. #CMT#USE : #/CMT# Method for testing of safety of transmission paths such as controller area network (CAN) bus within technical device used in modern complex facility such as process-technological plant, motor car, programmable controller, information-technical plant and railway vehicle. #CMT#ADVANTAGE : #/CMT# Since the safety relevance of the transmission paths on which outgoing signal is transferred is determined based on the safety relevance data corresponding to assigned outgoing signal, a determination can be made whether the transmission path is sufficient to transfer the signals safely so that usage of the transmission paths that does not correspond to the safety requirements of the signals which can be transferred to transmission path, into the technical device can be prevented. Hence the cost of the technical device can be reduced and the safety rating of the transmission paths in cross-linked technical facilities can be determined precisely. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a block diagram of the technical device. 1 : Technical device 11-13 : Technical function units U11-U13 : Transmission paths.
