多协议通信的远程PLC网络实验平台设计

Design of Remote PLC Network Experimental Platform for Multi-protocol Communication

基于西门子全集成平台,根据工业现场网络通信的特点,设计了一种多协议通信的远程PLC网络实验平台。以工业以太网为主干网,兼顾PROFIBUS-DP及串口通信模式,利用局域无线通信和远程VPN访问的模式,实现远程访问功能;采用虚拟工厂Factory IO和全集成自动化软件平台TIA,破解无法还原真实工业场景的难题。经过实验验证,该多协议通信远程PLC网络实验平台能实现远程访问,进行多种通信模式实验,观测到工业场景真实的控制效果。

Based on the fully integrated platform of Siemens and the characteristics of industrial field network communication,a remote PLC network experimental platform with multi-protocol communication was designed.The platform uses industrial Ethernet as the backbone network,taking into account PROFIBUS-DP and serial communication modes,and utilizes local wireless communication and remote VPN access modes to achieve remote access functions.By using virtual Factory IO and fully integrated automation software platform TIA,we can solve the problem of not being able to restore real industrial scenarios.After experimental verification,the multi protocol communication remote PLC network experimental platform can achieve remote access,conduct multiple communication mode experiments,and observe the real control effect in industrial scenarios.
