PLC提供了多种编程语言，其中梯形图使用*普遍。PLC是面向用户的设备，PLC的设计者充分考虑到现场工程技术人员的技能和习惯，因此PLC程序的编制采用梯形图的简单指令形式。梯形图与继电原理图相似，这种编程语言形象直观，易学易懂，不需要专门的计算机知识和语言，现场工程技术人员可在短时间内学会使用。用户在购买PLC后，只需按说明书的提示，做少量的接线和进行简易的用户程序编制工作，就可灵活方便地将PLC应用于生产实践。
PLC是通过执行程序实现控制的。当控制要求发生改变时，只要修改程序即可，*大限度地缩短了工艺更新所需要的时间。PLC的产品已标准化、系列化、模块化，而且PLC及配套产品的模块品种多，用户可以灵活方便地进行系统配置组合成各种不同规模、不同功能的控制系统。在PLC控制系统中，只需在PLC的端子上接入相应的输入/输出信号线即可，不需要进行大量且复杂的硬接线，并且PLC有较强的带负载能力，可以直接驱动一般的电磁阀和交流接触器。
