摘要
针对原有生产线系统存在的通信效率低下等问题,本文开发一种基于DP现场总线及工业以太网的新的通信方式的智能化生产线系统。主要分析模块化智能化生产线系统的结构和功能,并分析基于西门子最新PLC S7-1500为一级主站,TP700触摸屏为二级主站,七个西门子PLC S7-200为从站的DP通信方式、通信方法、通信步骤、程序结构和实现DP通信的程序设计方法等。应用效果评估表明,基于DP及以太网通信的智能化生产线系统提高了系统的通信效率,简化了硬件接线,可通过触摸屏对系统进行实时监控。验证了系统的可靠性、稳定性和抗干扰能力,使智能化生产线系统能够更加稳定、高效运行。
Aiming at the problems of low communication efficiency in the original production linesystem,an intelligent production line system based on DP field bus and industrial Ethernet is developed.Mainly analyzed are the structure and function of modular intelligent production line system,andanalysis of the latest SIEMENS PLC S7-1500is based on a master station,TP700touch screen for twomaster,seven SIEMENS PLC S7-200from DP communication station,communication method,programstructure and implementation steps,communication program design method DP communication,etc.Theapplication effect evaluation shows that the intelligent production line system based on DP and Ethernetcommunication can improve the communication efficiency of the system,simplify the connection ofhardware,and can monitor the system in real time by touch screen.The reliability and anti-interferenceability of the system are verified,and the intelligent production line training system can be operated moreefficiently and stably.
