摘要
本文通过现有地西门子模块和系统搭建ProfiNet IO实时以太网网络协议解析、测试和评估平台,对ProfiNet IO系统启动前寻址的实时报文结构中重要部分进行深入解析,结合Wireshark网络报文统计和分析工具,从基本内容、报文格式、工作原理等方面进行了分析。将ProfiNet中的DCP与LLDP相结合,实现控制器能够再现系统拓扑,无需组态工具进行设备替换。本文将会帮助自动化工程师加深对ProfiNet通信的理解,也为ProfiNet实时以太网数据监听、网络诊断和网络分析等打下了基础。
In this paper, through the existing Siemens module and system to build the ProfiNet IOreal time Ethernet network protocol analysis, test and evaluation platform, and the ProfiNet IO system launched before addressing the important part of the real-time message structure in-depth analysis, combined with Wireshark network packet statistics and analysis tools, from the basic content, message format, working principle and so on analysis. Combining the DCP and LLDP in ProfiNet, the controller can reproduce the system topology, and no configuration tool is needed to replace the device. This article will help the automation engineer to deepen understanding of ProfiNet communications. It also provides matting for ProfiNet real-time Ethernet data monitoring, network diagnosis and network analysis.
