基于以太网下的PLC与上位机通讯

随着科学技术的快速发展,中国的通讯技术、计算机技术和网络技术也不断地发展壮大,中国的工业自动化控制领域也得到了快速发展,通过运用一些先进的科学技术,把计算机技术,通信技术相结合成功的运用到工业技术中,并利用TCP/IP协议编程实现上位机的数据交换和数据通讯功能,不仅可以形成局域网络体系,而且通过对设备和Internet相连,也可以实现远程监控。这里主要介绍了PLC如何在以太网的基础之上实现与上位机的通信。

Ethernet-based PLC Communication with Host Computer

With the rapid development of science and technology,China＇s communications technology,computer technology and network technology grow uninterruptedly and China＇s industrial automatic control field also receives rapid development.By using the advanced science and technology,computer technology and communication technology are integratedly applied in the industrial technology,and also by using the TCP / IP protocol programming,the host computer data exchange and data communication function are realized,thus constituting a local area network system and through the connection of equipment and Internet,implementing the remote monitoring.This paper principally describes how to implement the Ethernet-based PLC communication with the host computer.
