Abstract
A method for setting up communication links to redundantly operated controllers in an industrial automation system, in which a first controller is in an active operating state for controlling or regulating a technical process, and a second controller is in a reserve operating state, from which it is placeable into an active operating state in the event the first controller fails, where the first/second controllers respectively store a device identifier associated with the first/second controllers, information about associations between device names and communication network addresses of the first/second controllers is provided in accordance with a name service protocol within at least one subnetwork associated with the first/second controllers, and where retrieval of a piece of address or name information for one of the two controllers involves automatically providing the piece of address or name information to setup a communication link to the other controller based on the respective device identifier.
