伴随着我国经济的快速发展,数控机床的数量越来越多,应用也越来越广泛,随着数控机床的发展需要,可编程序控制器(PLC)广泛应用于数控机床中,由于它可以通过软件来改变控制过程,而且具有体积小、功能强、可靠性高、抗干扰能力强、以及应用安装方便等优点,很快在我国的工业控制中占据了主导地位,现今已成为现代工业自动化的三大支柱(PLC技术、机器人、计算机辅助设计和制造)之一,并且还在不断发展。根据这一发展形势及需求,PLC技术已成为各类职业技术学校的一门必修课。
With the rapid development of economy in our country, the number of CNC machine tools is more and more widely used. With the development of CNC machine tools, PLCs are widely used in CNC machine tools, because it can Through the software to change the control process, and has the advantages of small size, strong function, high reliability, strong anti-interference ability, and easy application and installation, it quickly occupied the dominant position in China’s industrial control. Today it has become a modern industrial automation One of the three pillars (PLC Technology, Robotics, Computer Aided Design and Manufacturing) and is still evolving. According to this development situation and needs, PLC technology has become a compulsory course for all kinds of vocational and technical schools.
