Abstract

The present invention relates to a method for network restoration when a communication failure occurs in a RAPIEnet system. According to the present invention, through periodic transmission of a message for inspecting whether a network communication failure occurs 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 restore the network without imposing a burden on the network.

Description

technical field [0001] The present invention relates to the RAPIEnet system. In more detail, the present invention relates to a network recovery method when a communication failure occurs in a RAPIEnet system. In the RAPIEnet system, a method is used between a line network manager (Line Network Manager: LNM) device on a ring or line network or Ring Network Manager (RNM) periodically transmits messages to check whether there is a network communication failure, so that it can further accurately determine whether there is a network communication failure and correct it without burdening the network. recover. Background technique [0002] RAPIEnet refers to Ethernet-based industrial network protocol. This kind of industrial network is applicable to the automation of manufacturing processes such as semiconductors and automobiles, and the automation of power equipment. Considering temperature / chemical / noise / vibration, etc., most environments are harsh. For this reason, failures ...
