Abstract

A method and a system for transmitting data over a switchable network, especially Ethernet, in the field of industrial installations, in which real-time critical data and non real-time critical data is transmitted. The switchable data network has at least one wireless transmission link between at least two users, especially a transmitter and a receiver. When a communication interface is created by way of a coupling unit of the data network between cyclically clocked communication connections differing in performance, the data is forwarded according to a “store and forward” method. The method and system enable a parallel transmission of real-time critical and non real-time critical data.
