P0400ZE-FOXBORO

 ***处理单元(CPU)是可编程逻辑控制器的控制***。它按照可编程逻辑控制器系统程序赋予的功能接收并存储从编程器键入的用户程序和数据；检查电源、存储器、I/O以及警戒定时器的状态，并能诊断用户程序中的语法错误。当可编程逻辑控制器投入运行时，首先它以扫描的方式接收现场各输入装置的状态和数据，并分别存入I/O映象区，然后从用户程序存储器中逐条读取用户程序，经过命令解释后按指令的规定执行逻辑或算数运算的结果送入I/O映象区或数据寄存器内。等所有的用户程序执行完毕之后，***后将I/O映象区的各输出状态或输出寄存器内的数据传送到相应的输出装置，如此循环运行，直到停止运行。
