可编程控制器(Programmable Cont roller)简称PC,是一种以微处理器为核心的固态电路装置,是在传统的继电接触控制的基础上,结合先进微型计算机控制技术发展起来的新型工业控制器。它不仅可以取代以继电器、控制盘为主的顺序控制器,成为出色的《继电器库》,而且正在逐步应用于大规模的生产过程控制,近年来发展极为迅速,应用面愈益广泛、国外专家预言,作为工业自动化三大技术支柱之一的PC技术将跃居主导地位。
Programmable Cont roller (PC) is a microprocessor-based solid-state circuit device. It is a new type of industrial control developed on the basis of the traditional relay contact control combined with advanced microcomputer control technology Device. It can not only replace the relays, control panel-based sequence controller, become excellent “relay library”, and is gradually applied to large-scale production process control, the rapid development in recent years, more and more widely applied, foreign experts predict , PC technology, one of the three pillars of industrial automation, will take the lead.
