Abstract

An automation network comprises at least one primary subscriber, at least one switch, and at least one network subscriber. The primary subscriber comprises primary ports, the switch comprises switching ports, and the subscriber comprises subscriber ports, each comprising a transmitter and a receiver. The primary subscriber is configured to output first and second telegrams to first and second switching ports via first and second primary ports and first and second primary communication paths. The switch is configured to forward the first telegram to a first port of a network subscriber via a first subscriber communication path, and to forward the second telegram to a second port of a network subscriber via a second subscriber communication path. In an error mode, the switch and network subscriber are configured to return the first and/or second telegrams to the primary subscriber via the first and/or second primary port.
