PLC以微处理器为核心，具有微机的许多特点，但它的工作方式却与微机有很大不同。
微机一般采用等待命令的工作方式工作。
PLC是按集中输入、集中输出，周期性循环扫描的方式进行工作的。每一次循环扫描所用的时间称为一个扫描周期。
对每个程序，CPU从条指令开始执行，按顺序逐条地执行指令做周期性的程序循环扫描，如果无跳转指令，则从条指令开始逐条顺序执行用户程序，直至结束又返回条指令，如此周而复始不断循环。
PLC在每次扫描工作过程中除了执行用户程序外，还要完成内部处理、输入采样、通信服务、程序执行、自诊断、输出刷新等工作。PLC工作的全过程包括三个部分，即上电处理、扫描过程和出错处理。PLC工作的全过程可用图4所示的运行框图来表示。
PLC通电后，CPU在系统程序的控制下行内部处理，包括硬件初始化、I/O模块配置检查、停电保持范围设定及其他初始化处理等工作。
