Abstract: The present disclosure relates to a method for network recovery when a communication failure has occurred in a RAPIEnet system. According to the present disclosure, through periodic transmission of a message for inspecting whether a network communication failure has occurred between LNM devices or between RNMs in a ring- or line-shaped network in a RAPIEnet system, it is possible to accurately determine whether a network has a communication failure, and recover the network without imposing a burden on the network.
