描述

MPL-B540K-SJ22AA/A

编程器是PLC的重要外围设备。利用编程器将用户程序送入PLC的存储器,还可以用编程器检查程序,修改程序,监视PLC的工作状态。
常见的给PLC编程的装置有手持式编程器和计算机编程方式。在可编程序控制器发展的初期,使用专用编程器来编程。小型可编程序控制器使用价格较便宜、携带方便的手持式编程器,大中型可编程序控制器则使用以小CRT作为显示器的便携式编程器。专用编程器只能对某一厂家的某些产品编程,使用范围有限。手持式编程器不能直接输入和编辑梯形图,只能输入和编辑指令,但它有体积小,便于携带,可用于现场调试,价格便宜的优点。

计算机的普及,使得越来越多的用户使用基于个人计算机的编程软件。目前有的可编程序控制器厂商或经销商向用户提供编程软件,在个人计算机上添加适当的硬件接口和软件包,即可用个人计算机对PLC编程。利用微机作为编程器,可以直接编制并显示梯形图,程序可以存盘、打印、调试,对于查找故障非常有利。

CPU是可编程控制器的控制中枢,相当于人的大脑。CPU一般由控制电路、运算器和寄存器组成。这些电路通常都被封装在一个集成的芯片上。CPU通过地址总线、数据总线、控制总线与存储单元、输入输出接口电路连接。CPU的功能有:它在系统监控程序的控制下工作,通过扫描方式,将外部输入信号的状态写入输入映象寄存区域,PLC进入运行状态后,从存储器逐条读取用户指令,按指令规定的任务进行数据的传送、逻辑运算、算术运算等,然后将结果送到输出映像寄存区域。
CPU常用的微处理器有通用型微处理器、单片机和位片式计算机等。通用型微处理器常见的如Intel公司的8086、80186、到Pentium系列芯片,单片机型的微处理器如Intel公司的MCS-96系列单片机,位片式微处理器如AMD2900系列的微处理器。小型PLC的CPU多采用单片机或专用CPU,中型PLC的CPU大多采用16位微处理器或单片机,大型PLC的CPU多用高速位片式处理器,具有高速处理能力。

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。
