Abstract
There is described a communication system for reliable communication between communication stations, wherein there is at least one communication connection between the communication stations, wherein the communication connection features at least two channels for transmitting payload data telegrams, wherein only one channel acts as primary channel for the communication at any time, and wherein the other channels are provided as backup channels. A status indicator in the payload data telegram is provided for the indication of information concerning which channel is primary channel or backup channel at a given time point, wherein the communication stations adopt as primary channel that channel for which, during receipt of the payload data telegrams, the most recent status change from backup channel to primary channel was detected by the communication stations.
