中断的内容有很多种，比如外部中断、通信中的发送和接受中断、定时和计数的时钟中断、还有WDT复位中断等，它们丰富了在处理各种事务时响应种类。这样讲也许你并不能完全理解中断的内部结构和操作顺序，我们做一个小小的例子来说明.
每一个设备总是不会忘记有一个按钮，它也是在我们遇到紧急情况时使用的，那就是急停按钮。当我们遇到人身事故和意外情况时我们只要按下它，机器立即停止所有的操作，并等待处理完意外后再恢复操作。急停按钮连接PLC内部的内部I/O接口上，当按钮给一个外部触发信号时，对I/O进行再次检测，当确认有外部触发信号时，保护现场并将程序计数器自动转到相应的外部I/O中断程序中去，当外部中断程序处理完毕，程序计数器返回到主程序继续工作。有一点可以说明的是我们一般会把急停按钮的外部中断升至别，从而保证安全。
当我们在工作完一个工件时，给PLC一个信号，将PLC的内部计数器加1来计算我们的工作量时，一个简单的计数器能解决问题，当然它们也能够在掉电的情况下保持数据，促使数据不丢失，这也是我们所渴望的。
PLC还具有计数器的功能，当我们在接受一些高速的数据时，这里所说的高速是在在微秒级的数据，比如条码扫描机在不断的扫描数据，数据处理器DSP计算的高速信号等，我们就要采用到计数器来帮助我们进行计数。它在PLC执行程序时一旦发现计数器对应的中断，就会立即放下手上的工作。经过再次编程的梯形图程序说明我们在执行程序时计数器会自动的执行对应的工作，从而将计数器的级别升至高一级别。
