描述

A06B-6114-H207

PLC的基础技术的进展,主要集中在两个基本方面:执行多任务和程序互换。

所谓执行多任务,就是在一个PLC系统中可同时装几个CPU模块,每个CPU模块都执行某一种任务,控制与其所执行任务相关的I/O模块的存取。其实,按照IEC61131-3的概念,我们应该更确切地称之为通过多配置执行多任务。例如,三菱电机的小Q系列最多可以在一个机架上插4个CPU模块;富士电机的MICREX-SX系列最多可以在一个机架上插6个CPU模块。这些CPU模块可以是专门用于逻辑控制、顺序控制的,也可以是运动控制用的,还可以是做过程控制用的,上述在Windows操作系统的环境下执行PC机任务的模块,也是供用户选择的一种选项。从某种意义上讲,这也是一种混合式的控制系统。
PLC的传统软件模型包括一个资源,运行一个任务,控制一个程序,且运行于一个封闭系统中。而在IEC61131-3可编程控制器编程语言标准的软件模型中,在其最上层把解决一个具体控制问题的完整的软件概括为一个“配置”。它专指一个特定类型的控制系统,包括硬件装置、处理资源、I/O通道的存贮地址和系统能力,等同于一个PLC系统的应用程序。在一个由多台PLC或由多个CPU构成的PLC控制系统中,每一台PLC或每一个CPU的应用程序就是一个独立的“配置”。在一个“配置”中可以定义一个或多个“资源”。可把“资源”看作能执行IEC程序的处理手段,它反映PLC的物理结构,在程序和PLC的物理I/O通道之间提供了一个接口。只有在装入“资源”后才能执行IEC程序。一般而言,通常资源放在PLC内,当然它也可以放在其它支持IEC程序执行的系统内。在一个“资源”内可以定义一个或多个任务。任务被配置后可以控制一组程序或功能块。这些程序和功能块可以是周期地执行,也可以由一个事件驱动予以执行。

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。
