描述

870ITEC-AYFNZ-7

PLC是由摸仿原继电器控制原理发展起来的,二十世纪七十年代的PLC只有开关量逻辑控制,首先应用的是汽车制造行业。它以存储执行逻辑运算、顺序控制、定时、计数和运算等操作的指令;并通过数字输入和输出操作,来控制各类机械或生产过程。用户编制的控制程序表达了生产过程的工艺要求,并事先存入PLC的用户程序存储器中。运行时按存储程序的内容逐条执行,以完成工艺流程要求的操作。PLC的CPU内有指示程序步存储地址的程序计数器,在程序运行过程中,每执行一步该计数器自动加1,程序从起始步(步序号为零)起依次执行到最终步(通常为END指令),然后再返回起始步循环运算。PLC每完成一次循环操作所需的时间称为一个扫描周期。不同型号的PLC,循环扫描周期在1微秒到几十微秒之间。PLC用梯形图编程,在解算逻辑方面,表现出快速的优点,在微秒量级,解算1K逻辑程序不到1毫秒。它把所有的输入都当成开关量来处理,16位(也有32位的)为一个模拟量。大型PLC使用另外一个CPU来完成模拟量的运算。把计算结果送给PLC的控制器。
  相同I/O点数的系统,用PLC比用DCS,其成本要低一些(大约能省40%左右)。PLC没有专用操作站,它用的软件和硬件都是通用的,所以维护成本比DCS要低很多。一个PLC的控制器,可以接收几千个I/O点(最多可达8000多个I/O)。如果被控对象主要是设备连锁、回路很少,采用PLC较为合适。PLC由于采用通用监控软件,在设计企业的管理信息系统方面,要容易一些。
  近10年来,随着PLC价格的不断降低和用户需求的不断扩大,越来越多的中小设备开始采用PLC进行控制,PLC在我国的应用增长十分迅速。随着中国经济的高速发展和基础自动化水平的不断提高,今后一段时期内PLC在我国仍将保持高速增长势头。
  通用PLC应用于专用设备时可以认为它就是一个嵌入式控制器,但PLC相对一般嵌入式控制器而方具有更高的可靠性和更好的稳定性。实际工作中碰到的一些用户原来采用嵌入式控制器,现在正逐步用通用PLC或定制PLC取代嵌入式控制器,PLC产业一定会有一个美好的未来 。

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。
