描述

IC754VSI12CTD

功能强,性能价格比高
一台小型PLC内有成百上千个可供用户使用的编程元件,有很强的功能,可以实现非常复杂的控制功能。与相同功能的继电器相比,具有很高的性能价格比。可篇程序控制器可以通过通信联网,实现分散控制,集中管理。
硬件配套齐全,用户使用方便,适应性强
可编程序控制器产品已经标准化,系列化,模块化,配备有品种齐全的各种硬件装置供用户选用。用户能灵活方便的进行系统配置,组成不同的功能、不规模的系统。楞编程序控制器的安装接线也很方便,一般用接线端子连接外部接线。PLC有很强的带负载能力,可以直接驱动一般的电磁阀和交流接触器。
可靠性高,抗干扰能力强
传统的继电器控制系统中使用了大量的中间继电器、时间继电器。由于触点接触不良,容易出现故障,PLC用软件代替大量的中间继电器和时间继电器,仅剩下与输入和输出有关的少量硬件,接线可减少互继电器控制系统的1/10–1/100,因触点接触不良造成的故障大为减少。
 PLC采取了一系列硬件和软件抗干扰措施,具有很强的抗干扰能力,平均无故障时间达到数万小时以上,可以直接用于有强烈干扰的工业生产现场,PLC已被广大用户公认为最可靠的工业控制设备之一。
系统的设计、安装、调试工作量少
PLC用软件功能取代了继电器控制系统中大量的中间继电器、时间继电器、计数器等器件,使控制柜的设计、安装、接线工作量大大减少。
PLC的梯形图程序一般采用顺序控制设计方法。这种编程方法很有规律,很容易掌握。对于复杂的控制系统,梯形图的设计时间比设计继电器系统电路图的时间要少得多。
PLC的用户程序可以在实验室模拟调试,输入信号用小开关来模拟,通过PLC上的发光二极管可观察输出信号的状态。完成了系统的安装和接线后,在现场的统调过程中发现的问题一般通过修改程序就可以解决,系统的调试时间比继电器系统少得多。
编程方法简单
梯形图是使用得最多的可编程序控制器的编程语言,其电路符号和表达方式与继电器电路原理图相似,梯形图语言形象直观,易学易懂,熟悉继电器电路图的电气技术人员只要花几天时间就可以熟悉梯形图语言,并用来编制用户程序。
梯形图语言实际上是一种面向用户的一种高级语言,可编程序控制器在执行梯形图的程序时,用解释程序将它“翻译”成汇编语言后再去执行。
维修工作量少,维修方便
PLC的故障率很低,且有完善的自诊断和显示功能。PLC或外部的输入装置和执行机构发生故障时,可以根据PLC上的发光二极管或编程器提供的住处迅速的查明故障的原因,用更换模块的方法可以迅速地排除故障。
体积小,能耗低
对于复杂的控制系统,使用PLC后,可以减少大量的中间继电器和时间继电器,小型PLC的体积相当于几个继电器大小,因此可将开关柜的体积缩小到原来的确1/2-1/10。
PLC的配线比继电器控制系统的配线要少得多,故可以省下大量的配线和附件,减少大量的安装接线工时,可以减少大量费用。学得辛苦,做得舒服

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。
