工控机技术应用概述20世纪80年代,随着PLC技术的发展,继电器的控制方式逐渐被PLC所代替,大大减小了控制柜的体积,控制方式可以软件编程,简洁且易于维护。所以,当时大部分工控产品都尽可能采用了PLC技术。到20世纪90年代,随着人们对工控精度要求的不断提高,PLC控制方式越来越显示出它的局限性:图形显示困难、不能进行复杂的数学运算,人工的键盘干预不方便、计算速度偏慢、很难进行复杂的模拟量控制等。同时计算机技术在飞速发展,并开始涉及工业控制领域,产生了既有PLC满足工业
Industrial computer technology application overview In the 1980s, with the development of PLC technology, the relay control method was gradually replaced by PLC, greatly reducing the size of the control cabinet, the control mode can be software programming, simple and easy to maintain. Therefore, when most of the industrial products are used PLC technology as much as possible. By the 1990s, with the continuous improvement of industrial precision requirements, the PLC control method showed its limitations more and more: difficult to display graphics, complicated mathematical operations, inconvenient manual keyboard intervention and calculation speed Slow, it is difficult to carry out complex analog control. At the same time the rapid development of computer technology, and began to involve the field of industrial control, resulting in both PLC to meet industrial
