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。

执行器故障；
下面以FX系列PLC为例，来说明根据LED指示灯状况以诊断PLC故障原因的方法。
设计输入电路时，应尽量采用常开触点，如果只能用常闭触点，梯形图中对应触点的常开/常闭类型应与继电器电路相反。
在选择设备时，首先要选择有较高抗干扰能力的产品，其包括了电磁兼容性（EMC），尤其是抗外部干扰能力，如采用浮地技术、隔离性能好的PLC系统；其次还应了解生产厂给出的抗干扰指标，如共模拟制比、差模拟制比，耐压能力、允许在多大电场强度和多高频率的磁场强度环境中工作；另外是靠考查其在类似工作中的应用实绩。在选择国外进口产品要注意：我国是采用220V高内阻电网制式，而欧美地区是110V低内阻电网。由于我国电网内阻大，零点电位漂移大，地电位变化大，工业企业现场的电磁干扰至少要比欧美地区高4倍以上，对系统抗干扰性能要求更高，在国外能正常工作的PLC产品在国内工业就不一定能可靠运行，这就要在采用国外产品时，按我国的标准（GB/T13926）合理选择。
6、断电延时的时间继电器的处理，
顺序控制是PLC**基本、应用**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。

胶囊硫化工艺包括合模、紧模、保压硫化、启模等。胶囊硫化机通过控制上芯杆、下芯杆和主油缸的动作，组合成一定的芯模腔，形成胶囊硫化所需的压力，同时通过控制蒸汽的进入以控制硫化所需的温度。大部分胶囊硫化机采用液压系统。液压站通过油路管道来控制上芯模、下芯模和主油缸的升降动作。
