描述

PLC就是一个商品房，她是模块结构的产品，集成了控制需要的各种软硬件，包括指令、功能块、通信、IO接口、模拟量、温度、运控等各种功能。用户拿到后只需要进行简单的二次开发就可以满足要求，整个过程就像用积木搭一个房子一样。相反用单片机开发一个专用控制系统，从表面的物理成本上是降低了，但是人工和开发进度却不容乐观，一个最简单的单片机系统开发也需要四周左右，而使用PLC可能只需要一个小时。

PLC的可靠性是多年应用和严格实验保证的，无数不同行业不同厂商的应用使其的BUG减至最少，而单片机系统无法保证这一点。所以单片机系统的稳定性和可靠性要低很多，特别是系统刚开发的这一两年内，庞大的维护和升级费用将使你的成本急距上升。

当然如果你的控制对象量很多，而且对于可靠性要求不高，那么单片机一定是你最好的选择，比方说刚才说的空调、电视之类，这些产品的年产量都超过千万台，用单片机开发完全可以做到最低的成本，并且家用电器对于可靠性要求也不高，按两下按键不动，大不了再重新按一下，而在工控场合这是绝不允许的，比方说锅炉该动不动就有可能造成很大的事故。
