PLC也称之为可编程控制器,它是一种通用的自动控制装置,主要综合了计算机技术、通信技术以及自动控制技术而组成的。它能够充分将计算机的编程灵活、功能齐全、应用面广等优点进行有效的融合,从而得到广泛应用。曾有国外的专家就预感出,PLC技术必然会在自动化的三大支柱中脱颖而出。本文主要讲述了计算机和PLC通讯在自动输送线系统中的作用,从而使得人们能够对此得到进一步的了解。
PLC is also called programmable controller, it is a kind of general automatic control device, mainly composed of computer technology, communication technology and automatic control technology. It can fully computer programming flexibility, full-featured, wide range of applications and other advantages of effective integration, which has been widely used. Had foretold by foreign experts, PLC technology is bound to stand out in the three pillars of automation. This article focuses on the computer and PLC communications in the automatic transmission line system, so that people can get a better understanding of this.
