Abstract :
Ethernet networks for automation systems promise standardized interworking between completely different devices from field level up to office level without connection and conversion difficulties. As Ethernet was not originally developed considering automation system requirements, its qualification, especially regarding topology and determinism demands, has to be examined. Theoretical calculations on topology influence are completed by measurements on switch hardware. A special software for configuring, monitoring and testing the switch hardware was developed. Further experiments for the evaluation of the Ethernet Medium Access Control Pause operation in automation systems are also described
