Method and system for coupling data networks

摘要

The invention relates to a method and a system for transmitting data by means of a first data network 1 having first means for transmitting data in at least one first transmission cycle, the first transmission cycle being subdivided into a first area 4 for transmitting real-time-critical data and a second area 5 for transmitting non-real-time-critical data, and by means of a second data network 2 having second means for transmitting data in at least one second transmission cycle, the second transmission cycle being subdivided into a third area 7 for transmitting real-time-critical data and into a fourth area 8 for transmitting non-real-time-critical data, and with a switching unit 13 for transmitting real-time-critical data of the first area into the third area.
