简化的程序结构：PLC的程序结构通常很简单，典型的为块式结构，不同块完成不同的功能，使程序的调试者对整个程序的控制功能和控制顺序有清晰的概念。
4.简化应用软件生成过程：使用汇编语言和语言编写程序，要完成编辑、编译和连接三个过程，而使用编程语言，只需要编辑一个过程，其余由系统软件自动完成，整个编辑过程都在人机对话下进行的，不要求用户有高深的软件设计能力。
5.强化调试手段：无论是汇编程序，还是语言程序调试，都是令编辑人员头疼的事，而PLC的程序调试提供了完备的条件，使用编程器，利用PLC和编程器上的按键、显示和内部编辑、调试、监控等，并在软件支持下，诊断和调试操作都很简单。
总之，PLC的编程语言是面向用户的，对使用者不要求具备高深的知识、不需要长时间的专门训练。
- 2编程语言的形式
本教材采用常用的两种编程语言，一是梯形图，二是助记符语言表。采用梯形图编程，因为它直观易懂，但需要一台个人计算机及相应的编程软件；采用助记符形式便于实验，因为它只需要一台简易编程器，而不必用昂贵的图形编程器或计算机来编程。
虽然一些的PLC还具有与计算机兼容的C语言、BASIC语言、专用的语言（如西门子公司的GRAPH5、三菱公司的MELSAP），还有用布尔逻辑语言、通用计算机兼容的汇编语言等。不管怎么样，各厂家的编程语言都只能适用于本厂的产品。
