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.

Abstract: The present disclosure relates to a method for managing a parameter of a communication-based master-slave control system, and has an effect of storing and applying parameters of all slave devices in a non-volatile memory in a master device, thereby enabling the slave devices to be set-up in a position where an operator is difficult to access or dangerous by a parameter stored in the master device, thereby simplifying maintenance of the slave devices and ensuring safety of a user.

Abstract: A communication device according to an embodiment of the present disclosure comprises: a communicator; and a processor configured to: if a network composed of a first topology including a star topology or a line topology is included on a communication path connecting the communication device and the other communication device, configure data to be transmitted to the other communication device through a first interface for accessing a RAPIEnet (Real-time Automation Protocol for Industrial Ethernet)-based upper layer and an Internet Protocol (IP)-based lower layer, and transmit the data to the other communication device through the communicator using the communication path.
