As a consequence, a great need for communication solutions with regard to those application functions arose. These had to be executed as software, which was logically connected but technically allocated to distributed equipment. In this paper the influence of this development on automation systems will be discussed, particularly the special subject of Industrial communication with its high demand on the Quality of Service.}, identifier = {06004567}, }
