| 详细介绍： ＰＬＣ机型选择的基本原则是，在功能满足要求的前提下，选择最可靠、维护使用最方便以及性能价格比的最优化机型。
在工艺过程比较固定、环境条件较好（维修量较小）的场合，建议选用整体式结构的ＰＬＣ；其它情况则最好选用模块式结构的ＰＬＣ。
对于开关量控制以及以开关量控制为主、带少量模拟量控制的工程项目中，一般其控制速度无须考虑，因此，选用带Ａ／Ｄ转换、Ｄ／Ａ转换、加减运算、数据传送功能的低档机就能满足要求。
而在控制比较复杂，控制功能要求比较高的工程项目中（如要实现ＰＩＤ运算、闭环控制、通信联网等），可视控制规模及复杂程度来选用中档或高档机。其中高档机主要用于大规模过程控制、全ＰＬＣ的分布式控制系统以及整个工厂的自动化等。根据不同的应用对象，表１列出了ＰＬＣ的几种功能选择。
现在的 PLC 能够支持多种通信协议。比如现在比较流行的工业以太网等 对通信有特殊要求的用户
对于一个大型企业系统，应尽量做到机型统一。这样，同一机型的ＰＬＣ模块可互为备用，便于备品备件的采购和管理；同时，其统一的功能及编程方法也有利于技术力量的培训、技术水平的提高和功能的开发；此外，由于其外部设备通用，资源可以共享，因此，配以上位计算机后即可把控制各独立系统的多台ＰＬＣ联成一个多级分布式控制系统，这样便于相互通信，集中管理。
