顺序控制是PLC最基本、应用最广泛的领域。所谓的顺序控制，就是按照工艺流程的顺序，在控制信号的作用下，使得生产过程的各个执行机构自动地按照顺序动作。由于它还具有编程设计灵活、速度快、可靠性高、成本低、便于维护等优点，所以在实现单机控制、多机群控制、生产流程控制中可以完全取代传统的继电器接触器控制系统。它主要是根据操作按扭、限位开关及其它现场给来的指令信号和传感器信号，控制机械运动部件进行相应的操作，从而达到了自动化生产线控制。比较典型应用在自动电梯的控制、管道上电磁伐的自动开启和关闭、皮带运输机的顺序启动等。例如我分厂的原料混料系统就是利用了PLC的顺序控制功能。
目前，PLC制造厂家相继推出了一些具有特殊功能的I／O模块，有的还推出了自带CPU的智能型I／O模块，如高速计数器、凸轮模拟器、位置控制模块、PID控制模块、通信模块等。
其他功能模块
实验、实训与上机课可以采用自主学习方式。自主学习方式是一种学习者在总体教学目标的宏观调控下，在教师的指导下，根据自身条件和需要自由地选择学习目标，学习内容和方法，并通过自我调控的学习活动完成具体学习目标的学习方式。自主学习离不开教师的适时指导与评价，学生只有在教师的适时帮助下，才能不断地完成一个又一个实验与实训项目，获得越来越大的成就感，增加自己自主学习的动力，从而保证自主学习方式的良性发展。教师还必须结合理论课程的进程，结合实验实训设备编写由浅入深、逐步递进、面向不同层次学生的实验实训指导书，为学生的自主学习提供有力的理论支撑。
根据工作功能图表或状态流程图等设计出梯形图即编程。这一步是整个应用系统设计的核心工作，也是比较困难的一步，要设计好梯形图，首先要十分熟悉控制要求，同时还要有一定的电气设计的实践经验
