To handle transient faults of the communication in industrial Ethernet effectively,a multi-level fault-handling mechanism based on chip,node and system is proposed.According to characteristics in transient faults of the communication in Industrial Ethernet,causes of transient faults are analyzed from different hierarchies.Then,the correspond disposal methods are designed,in which the chips working condition could be changed automatically due to hardware logic and software control are used in the chip level,the software watchdog and software redundancy are employed in the node level,defining a special frame format and setting the timer is applied in the system level.The experimental results indicate that packet loss is decreased by using the multi-level transient fault-handling mechanism.Thus the reliability of the system is enhanced.
