3180-EPI
如何抉择PLC和DCS系统
    在可编程逻辑控制器（PLC）和分散式控制系统（DCS）之间如何抉择，要具体情况具体分析，因为应用场合不同，对控制系统的要求也各不相同。
    控制系统平台，对自动化系统满足优化生产、维持可用性和获取数据等需求的方式，会有一定的影响。在选择控制系统方面缺乏远见，也可能会影响未来的扩展、流程优化、用户满意度和公司利润。
    除了一些基本准则之外（比如如何控制过程），设计团队还必须考虑安装、可扩展性、维护、保养等方面的各种因素。
    目前，虽然对小设备来讲，PLC系统可能是最划算的，但DCS系统则提供了更具经济性的可扩展能力，更可能获得较高的初始投资回报。
    PLC是一种工业计算机，用于控制生产制造过程，如机器人、高速包装、装瓶和运动控制等。在过去20年里，PLC增添了更多的功能，为小型工厂和装置创造了更多的效益。PLC通常是单机系统运行，但也可以与其它系统集成，经由通信来实现彼此之间的连接。由于每个PLC都有自己的数据库，因此集成需要控制器之间某种程度的映射。这使PLC特别适用于那些对扩展没有太大需求的小型应用程序。
DCS系统则将控制器分散在自动化系统中，并提供通用的接口、先进的控制、系统级数据库以及易于共享的信息。传统上，DCS主要应用于过程工艺和比较大的工厂，在整个工厂的生命周期中，大型系统应用程序更容易护。

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。
