（2）调整编码器的频率至20HZ。重复（1）的操作，观察计数器的当前值，与（1）有什么不同？为什么？
电源电路画成水平线，三相交流电源相序L1、L2、L3由上而下排列，中线N和保护地线PE画在相线之下。直流电源则正端在上，负端在下画出。
第一部分是上电处理。PLC上电后对系统进行一次初始化，包括硬件初始化和软件初始化，停电保持范围设定及其他初始化处理等。
小型PLC的CPU采用8位或16位微处理器或单片机，如8031、M68000等，这类芯片价格很低；中型PLC的CPU采用16位或32位微处理器或单片机，如8086、96系列单片机等，这类芯片主要特点是集成度高、运算速度快且可靠性高；而大型PLC则需采用高速位片式微处理器
（3）可编程控制器有监视定时器等自检功能，检查出异常时，输出全部关闭。但当可编程控制器CPU故障时就不能控制输出，因此，对于能使用户造成伤害的危险负载，为确保设备在状态下运行，需设计外电路加以防护。
在作出系统控制方案的决策之前，要详细了解被控对象的控制要求，从而决定是否选用PLC进行控制
