摘要
实时以太网自动化系统通讯要求的逐步提高,如何测试实时以太网设备通讯性能至关重要。本文在深入研究实时以太网技术的基础上,借助于德国赫优讯最新实时以太网分析仪netANALYZER,通过搭建PROFINET实时以太网网络通讯平台,结合PROFINET的技术协议,利用Wireshark网络报文分析工具,对PFOFINET时间抖动进行了深入的研究和分析。
For the requirement of automation communication becoming more and more strict, the research on real-time Ethernet becoming more and more deep, the device based on real-time Ethernet also becoming more and more, but the problem is how to test these real-time Ethernet device, it is the most important process. This article is to resolve this question by netANALYZER from Hilscher, which is analysis device for realtime Ethernet, and the article take PRQFINET system for example, after setup the platform of PROFINET system, and by wireshark software, we will analysis and deep research the Time-Jitter of PROFINET.
