Method for message transmission in a redundant industrial communication network and communication device for a redundant industrial communication network

摘要

The method involves configuring topology information for a subnetwork (1) that comprises a virtual network node. The topology information is configured as received topology information for the subnetwork at a respective virtual terminal connection (20) of a communication device (201). A failure of the communication device associated with the node is handled. A connection between network nodes of another subnetwork (2) is performed with one of a parallel or ring redundancy protocol. A configuration of the network node is provided as a root network node of the former subnetwork being retained. An independent claim is also included for a communication device.
