近年来随着工业以太网(Industrial Ethernet)技术的飞速发展,PLC之间的通信越来越多地利用工业以太网来进行数据传输。本文以西门子的S7-400、300PLC之间的通信为例,详细地介绍了ISO-on-TCP这种连接方式的组态与编程的方法。
In recent years, with the rapid development of Industrial Ethernet technology, communication between PLCs increasingly uses Industrial Ethernet for data transmission. In this paper, Siemens S7-400, 300PLC communication as an example, a detailed introduction to ISO-on-TCP this connection configuration and programming methods.
