描述

KJ3204X1-BA1

 近几年来，可编程序控制器(PLC)以其可靠性高、适应性强、灵活性好、编程简单、容易掌握等特性，在各个领域发挥越来越重要的作用。在PLC控制系统中，PLC作为主要控制设备，必然与控制对象中各种输入信号(如按钮、限位开关、拔动开关、继电器的触点及其它检测信号等)和输出设备(如继电器线圈、接触器线圈、电磁阀等执行元件)相关联。在实际工作中，由于受PLC应用系统规模的限制，PLC输入/输出点数往往不够用。为此若采用扩展输入/输出单元或更换点数更多的PLC来解决有时又不合算，为了降低系统硬件的成本，常常采用各种技巧减少系统占用的输入/输出点数，相当于扩展了PLC的I/O点数。本文从硬件、软件两个方面介绍在不增加硬件情况下“扩展”PLCI/O点数的几种方法。
    2“扩展”I/O点数的方法
    2.1分组输入
    有些PLC控制既有“手动控制”又有“自动控制”，而自动控制程序和手动控制程序不会同时执行，这时可将自动与手动信号按不同控制状态要求分组接入PLC输入端子，如图1所示(本文以三菱FX2小型PLC编号分配为例进行梯形图设计)。图1中SA用来选择自动/手动程序，供自动/手动切换之用，SB2和SB1按钮都使用X0输入端，但它们不会同时起作用，图1中的二极管用来切断寄生信号，避免错误信号的产生。这样，通过PLC的硬件公共点(COM)接线的转换和软件分时执行各自不同的用户程序段的方法，使得PLC的一个输入点可分别反应两个输入信号的状态，起到两个输入点的作用，来完成PLC在两种工作状态下的输入功能，提高了PLC输入点的利用效率，相当于扩展了PLC的输入点的实际数量。其它X1-X7端相似。

先介绍几点经验。
1、先通读一遍“系统手册”（不管能不能看懂，先了解个大概，以便学习编程时查找）；
2、由位控逻辑入手，逐渐增加定时、计数等条件，把或、与、非关系理顺；
3、进而练习整数运算、实数运算、类型转换；
4、量程转换、PID调节回路的建立及P、I、D参数的理解（最好是有个物理回路验证，比如变频器+电机+测速传感器）；
5、循环、顺序、跳转等程序控制（尽量避免跳转，非跳不可时也是跳的越近越好）；
6、中断、通讯、位置控制....

本人以ABB工业机器人配件DSQC系列和Motorola MVME系列，GE 卡件 模块 驱动器系列为主攻。各位电工朋友可根据自己的条件选择适合自己的PLC品牌，由于PLC的基本框架大同小异，学会一种至于其它的学习起来也就简单了。
