The invention relates to a method for operating a transmission system () that comprises a first network () and at least one additional network (), in which data are exchanged between said at least two networks () by means of data of the first network () being fed to duplication means () in the form of data packets, these fed data packets being wirelessly transmitted to separator means () via at least two transmission paths () using PRP, and being forwarded from said separator means () to the connected additional network () in the form of a data stream. The invention is characterized in that the data packets are temporarily stored in a memory once they have been transmitted via the at least two transmission paths ().

Method of operating a redundant PRP

A method of operating a transmission system () having a first network () and at least one second network () where data is exchanged in that data of the first network () is inputted between these at least two networks () into duplication means (), and the inputted data is transmitted wirelessly via at least two transmission paths () using PRP to separator means () and forwarded from the separating means () to the connected second network (), characterized in that the data is transmitted as data packets and each data packet is transmitted several times via the same transmission path ().

Redundant transmission system for PRP and multiple data packets

A method of operating a transmission system () having a first network () and at least one second network (), data being exchanged between these at least two networks () in that data of the first network () is fed to duplication means (), the inputted data being transmitted wirelessly to separator means () via at least two transmission paths () using PRP and forwarded from the separator means () to the connected second network (), characterized in that the data is transmitted in the form of data packets, and it is ascertained whether or not a data packet was transmitted, and it is determined based thereon whether or not the transmission system () is operating in a fault-free manner.
