1、理论课的任务是让学生明确PLC是什么?PLC能做什么?怎么做?教师可以通过一个简单、形象实例(如:电机的长动控制)的完整讲解、操作与演示,先让学生了解PLC控制系统包括主电路与控制电路,PLC的外部硬件连线与内部软件编程两个基本的环节仅仅充当控制电路部分,让学生整体了解PLC控制系统的构成与工作过程,再以此为基础进行外部硬件连线与内部软件编程两个基本环节的深入讲解,这样便于学生对比继电接触器控制系统对本课程的整体把握,明确课程的中心任务,有了目标也就有了学习的动力。
理论课教学过程中要使用多媒体教学手段,利用多种计算机技术制作以PPT为主体的电子课件,借助多媒体技术,用生动丰富的画面和美妙动听的音乐效果吸引学生的注意力,激发学生的学习兴趣,同时可以提高教学的效率。PLC的外部接线(包括主电路接线)首先讲原理图,结合实验、实训、实习讲解装配图与实际连线图,要让学生体会课堂上的原理图、实验中的接线与实训、实习中的接线的区别与联系,教会学生善于理论联系实践,以理论指导实践,以实践验证理论。
当前流行的三菱PLC的编程软件为FXGP_WIN-C与GXDeveloper,FXGP_WIN-C没有仿真功能,在理论讲授中缺乏直观性,而GXDeveloper编程软件加装GXSimulator6-C后具有仿真功能,在编程器件、指令与编程实例的讲解中利用仿真可以加强直观性,便于学生的理解,对于某些程序的检验与编写学生可以不用到实验室,直接利用学校机房结合软件的仿真功能完成,这样既增强了学生自主学习的能力,提高了学习兴趣,也提高了学习的效率,学生不用走进实验室也能使理论教学与实验教学同步进行,大大提高老师的教学效果以及学生的理解和接受能力。
