描述

ECPA81-2

PLC以微处理器为核心，具有微机的许多特点，但它的工作方式却与微机有很大不同。
    微机一般采用等待命令的工作方式工作。
    PLC是按集中输入、集中输出，周期性循环扫描的方式进行工作的。每一次循环扫描所用的时间称为一个扫描周期。
    对每个程序，CPU从第一条指令开始执行，按顺序逐条地执行指令做周期性的程序循环扫描，如果无跳转指令，则从第一条指令开始逐条顺序执行用户程序，直至结束又返回第一条指令，如此周而复始不断循环。
    PLC在每次扫描工作过程中除了执行用户程序外，还要完成内部处理、输入采样、通信服务、程序执行、自诊断、输出刷新等工作。PLC工作的全过程包括三个部分，即上电处理、扫描过程和出错处理。PLC工作的全过程可用图4所示的运行框图来表示。
    PLC通电后，CPU在系统程序的控制下先进行内部处理，包括硬件初始化、I/O模块配置检查、停电保持范围设定及其他初始化处理等工作。
    PLC有很强的自诊断功能，PLC每扫描一次执行一次自诊断检查，确定PLC自身的动作是否正常，如电源检测、内部硬件是否正常、程序语法是否有错等。如检查出异常时，CPU面板的LED及异常继电器会接通，在特殊寄存器中会存入出错代码；CPU能根据错误类型和程度发出信号，甚至进行相应的出错处理，使PLC停止扫描或强制变成STOP状态。
    PLC运行正常时，扫描周期的长短与用户应用程序的长短、CPU的运算速度、I/O点的情况等有关。通常用PLC执行1KB指令所需时间来说明其扫描速度（一般1-10ms/KB）。值得注意的是，不同指令执行时间是不同的，故选用不同指令所用的扫描时间将会不同。若用于高速系统要缩短扫描周期时，可从软硬件上同时考虑。PLC周期性循环扫描工作方式的显著特点是：可靠性高、抗干扰能力强，但响应滞后、速度慢。

选择深圳长欣，选择放心，售后无忧大量现货，当天顺丰发货！
主营：本特利，英维思，伍德沃德，福克斯波罗、西屋、瑞恩、施耐德莫迪康、ABB、AB、西门子、摩托罗拉、GE发那科、安川、博世力士乐，ACSO，力士乐等各大品牌的DCS系统配件，机器人系统配件，大型伺服系统备件。

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。
