可编程控制器（programmable logical controller，简称PLC）已经越来越多地应用于工业控制系统中，并且在自动控制系统中起着重要的作用。所以，对PLC的正确选择是重要的。
面对众多生产厂家的各种类型PLC，它们各有优缺点，能够满足用户的各种需求，但在形态、组成、功能、网络、编程等方面各不相容，没有一个统一的标准，无法进行横向比较。下面提出在自动控制系统设计中对PLC选型的一些看法，可以在挑选PLC时作为参考。
可以通过以下几方面的比较，挑选到适合的产品。
这一点尤为重要。在自动控制系统设计之初，就应该对控制点数（数字量及模拟量）有一个准确的统计，这往往是选择PLC的首要条件，一般选择比控制点数多10%~30%的PLC。这有几方面的考虑：
1、可以弥补设计过程中遗漏的点；
2、能够在运行过程中个别点有故障时，可以有替代点；
3、将来增加点数的需要。
工作环境是PLC工作的硬性指标。自控系统将人们从繁忙的工作和恶劣的环境中解脱出来，就要求自控系统能够适应复杂的环境，诸如温度、湿度、噪音、信号、工作电压等，各款PLC不尽相同。一定要选择适应实际工作环境的产品。
