简述工业控制中PLC的一些关键应用技术

Briefly Describe Some Key Application Technologies of PLC in Industrial Control

现在及未来10-20年,电气自动化将会越来越体现出它的作用与重要性!电气自动化为什么会在工业控制中起到如此重要的作用,正是因为它的灵活性、基于电子技术及互联网开发的控制器的先进性,往往在非标机械实现控制应用的场合中代替机械所不能实现的一些功能;在电气自动化控制中通讯技术的作用更为突出,它能实现设备与设备之间数据的传输、随着技术的发展,通讯的方式多种多样,速度越来越快,稳定性也越来越高,在工业控制中大大降低了投入成本;本次论述主要围绕PLC在工业控制中的一些关键技术的应用,进而表明它的重要性。

Now and in the next 10-20 years,electrical automation will increasingly reflect its role and importance!Why does electrical automation play such an important role in industrial control?It is precisely because of its flexibility and the advanced nature of controllers developed based on electronic technology and Internet that it often replaces machinery in the occasions where non-standard machinery realizes control applications.Some functions that cannot be realized;the role of communication technology in electrical automation control is more prominent,it can realize the transmission of data between equipment and equipment,with the development of technology,communication methods are various,and the speed is getting faster and faster.The stability is also getting higher and higher,which greatly reduces the input cost in industrial control;this discussion mainly focuses on the application of some key technologies of PLC in industrial control,and then shows its importance.
