Abstract

A redundantly operable communication system for an industrial automation system, wherein a first communication device is redundantly connected to a third communication network connection of first and second network infrastructure devices, the second communication device is redundantly connected to a third communication network connection of a third and fourth network infrastructure device, where the first and third network infrastructure device and the second and fourth network infrastructure devices are interconnected via their first and second communication network connections such that, while the first and second communication device identify data frames to be redundantly transmitted via a first indicator, the first and third network infrastructure devices and the second and fourth network infrastructure devices identify data frames to be redundantly transmitted via a second or third indicator that differs from the first indicator, and reject data frames received on the third communication connection and identified via the second or third indicator.
