Abstract

Method for setting up a redundant communication connection, and failsafe control unit, wherein a transport and/or networking functional unit of a communication device utilizes at least one communication network address associated with a primary control device and/or a secondary control device to set up two communication connections to a failsafe control unit that includes the primary control device and the secondary control device, where data transmitted via a first communication connection are forwarded from the primary control device to the secondary control device via a first synchronization connection such that data transmitted via a second communication connection are forwarded from the secondary control device to the primary control device via a second synchronization connection.
