摘要
提出一种基于网络的多模式PLC实训系统。该系统采用西门子公司新型控制器1200、1500、S7-200SMART和传统的S7-400、S7-300、S7-200控制集成,采用工业以太网和PROFIBUS-DP的通信模式,实现现场级、控制级、管理级的三层网络系统的信息传递。可以用以太网完全实现三层网络控制,也能实现各种控制器之间的以太网、PROFIBUS-DP、PPI和USS协议等通信模式。系统端口开放,具有扩展和级联其他设备的功能。该实训系统对提高师生解决复杂工程问题的能力有积极作用。
In this paper, a multiple model based on network PLC training system was researched.The system adopts the new controller 1200, 1500, Siemens S7-200 smart and traditional S7-400, S7-300, S7-200 control integration, using industrial Ethernet and PROFIBUS-DP communication mode,which implement the information transmission among site level, control level and management level.The system not only realize the three layer network control,but aslo can realize the commumication among the ethernet, PPI and uss protocol.System port is open, and have the function of extension and cascade of other equipment.The training system for improving the ability of the teachers and students to solve complex engineering problems plays a positive role.
