摘要
在工业控制的实际应用中经常遇到两台或多台PLC之间的数据传送,随着现场总线技术的发展,以太网通信受到广泛关注。通过TIA Porta全集成自动化软件,本文以两台西门子S7-1200 PLC为研究对象,对现在常用的以太网通信中的两种典型通信方式S7通信和PROFINET IO通信进行了对比研究与介绍。
In the actual application of industrial control,communication between two or more PLCs is often encountered.With the development of fieldbus technology,Ethernet communication has attracted widespread attention.Through TIA Porta fully integrated automation software,this article takes two Siemens S7-1200 PLCs as the research object,a comparative study and introduction to the two typical communication modes S7 communication and PROFINET IO communication in the commonly used Ethernet communication.
