PLC is not a single programming technology,it is a system professional course.PLC can be broadly considered as a highly reliable PC with embedded operating system.First of all,it is necessary to deepen the programming language ladder diagram and statement list language of PLC itself.At this level,you can only read and understand the programmed programs,and can design some engineering programs.In this industry,VB and VC++are also needed to realize serial communication and distributed control system.Database knowledge is also required in some large programs.
PLC并不是一门单一的编程技术,它是一门系统专业课程。PLC可以广义的认为是一台背嵌入操作系统的高可靠性PC机。首先需要精深PLC本身的编程语言梯形图、语句表语言。达到这个水平你只能读懂编好的程序,并可以设计一些工程需要程序。在这行业还需要应用VB、VC++实现串口的通信,集散控制系统。在一些大型程序中还需要用到数据库的知识。
