Measurements in Switched Ethernet Networks Used for Automation Systems
نویسندگان
چکیده
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. In this paper 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

Analysis of Switched Ethernet Networks with different Topologies used in Automation Systems
Ethernet is the most famous type of communication network used for office applications. Currently, networks used on field level and on office level are different due to their specific requirements. Especially for real-time systems, the deterministic behavior of the network is very important. Now Switched Ethernet seems to be applicable also on field level, because collisions can be avoided and ...
متن کاملAnalysis of Network Traffic in Switched Ethernet Systems
A 100 Mbps Ethernet link between a college campus and the outside world was monitored with a dedicated PC and the measured data analysed for its statistical properties. Similar measurements were taken at an internal node of the network. The networks in both cases are a fullduplex switched Ethernet. Inter-event interval histograms and power spectra of the throughput aggregated for 10ms bins were...
متن کاملRETHER: A Software-Only Real-Time Ethernet for PLC Networks
The networking technologies used in industrial automation are required to support real-time performance guarantees to ensure that sensor/command data reach target nodes within a delay bound. With the continuing popularity and thus the accompanied price drop of the Ethernet technology, replacing the typically closed and proprietary automation networks with Ethernet is emerging as a very attracti...
متن کاملReal Time Characteristics of Ethernet and Its Improvement
There is a growing interest of using Ethernet to support time constrained communication raised from process control, factory automation and other real-time applications. This paper first presents a comprehensive analysis of the temporal characteristics of traditional Ethernet and the improvements for them, then summarizes the interesting features offered by a switched Ethernet for supporting ti...
متن کاملLow-latency Hard Real-Time Communication over Switched Ethernet
Ethernet, the most widely used commodity network, increasingly moves toward switches as implementation technology thus replacing busses. This allows to use traf£c shaping techniques to implement hard real-time distributed systems on commodity networks. However, because Ethernet switches lack build-in policing features, nodes connected by Switched Ethernet need to be cooperative. Although the th...
