Abstract:
1. A method for transmitting and changing a data telegram from a non-realtime domain into a realtime-data telegram for a realtime domain, comprising: creating a non-realtime data telegram with a useful data zone, the useful data zone including useful data and an identification for designating the data telegram as realtime or non-realtime; transmitting the data telegram via a non-realtime network to a switching coupling unit; receiving the data telegram through a first port of the switching coupling unit, the first port of the switching unit arranged to couple the switching coupling unit to the non-realtime network, the first port further arranged to pass exclusively non-real time data; checking, by the switching coupling unit, the data telegram to determine whether the identification designates realtime or non-realtime; if the identification designates realtime, separating the useful data and the identification from the useful data zone of the data telegram and transferring the useful data and the identification from the useful data zone to a communication memory; storing the useful data in a storage zone of the communication memory; cyclically processing the useful data to create a realtime-data telegram from the useful data stored in the communication memory, thereby changing a data telegram from a non-realtime domain to a realtime-data telegram for use in the realtime domain; and forwarding the realtime-data telegram in the realtime domain through a realtime network coupled to a second port of the switching coupling unit, the second port arranged to pass at least realtime data.
