描述

P-HA-RPS-32200000

良好的接地是保证PLC可靠工作的重要条件,可以避免偶然发生的电压冲击危害。PLC的接地线与机器的接地端相接,接地线的截面积应不小于2mm2,接地电阻小于100Ω;如果要用扩展单元,其接地点应与基本单元的接地点接在一起。为了抑制加在电源及输入端、输出端的干扰,应给PLC接上专用地线,接地点应与动力设备(如电机)的接地点分开;若达不到这种要求,也必须做到与其它设备公共接地,禁止与其它设备串连接地。接地点应尽可能靠近PLC。在石油、化工、冶金等行业的某些系统中,要求控制装置有极高的可靠性。如果控制系统发生故障,将会造成停产、原料大量浪费或设备损坏,给企业造成极大的经济损失。但是仅靠提高控制系统硬件的可靠性来满足上述要求是远远不够的,因为PLC本身可靠性的提高是有一定的限度。使用冗余系统或热备用系统就能够比较有效地解决上述问题。

为了使各位初学者更方便地了解PLC,本文对PLC的发展、基本结构、配置、应用等基本知识作一简介。
    在自动化控制领域,PLC是一种重要的控制设备。目前,世界上有200多厂家生产300多品种PLC产品,应用在汽车(23%)、粮食加工(16.4%)、化学/制药(14.6%)、金属/矿山(11.5%)、纸浆/造纸(11.3%)等行业。为了使各位初学者更方便地了解PLC,本文对PLC的发展、基本结构、配置、应用等基本知识作一简介,以期对各位网友有所帮助。  在工业生产过程中,大量的开关量顺序控制,它按照逻辑条件进行顺序动作,并按照逻辑关系进行连锁保护动作的控制,及大量离散量的数据采集。传统上,这些功能是通过气动或电气控制系统来实现的。1968年美国GM(通用汽车)公司提出取代继电气控制装置的要求,第二年,美国数字公司研制出了基于集成电路和电子技术的控制装置,首次采用程序化的手段应用于电气控制,这就是第一代可编程序控制器,称ProgrammableController(PC)。

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。
