主机部分包括处理器(CPU)、系统程序存储器和用户程序及数据存储器。CPU是PLC的核心,它用以运行用户程序、监控输入/输出接口状态、作出逻 辑判断和进行数据处理,即读取输入变量、完成用户指令规定的各种操作,将结果送到输出端,并响应外部设备(如电脑、打印机等)的请求以及进行各种内部判断 等。PLC的内部存储器有两类,一类是系统程序存储器,主要存放系统管理和监控程序及对用户程序作编译处理的程序,系统程序已由厂家固定,用户不能更改; 另一类是用户程序及数据存储器,主要存放用户编制的应用程序及各种暂存数据和中间结果。
PLC与电气回路的接口,是通过输入输出部分(I/O)完成的。I/O模块集成了PLC的I/O电路,其输入暂存器反映输入信号状态,输出点反映输出锁存器状态。输入模块将电信号变换成数字信号进入PLC系统,输出模块相反。I/O分为开关量输入(DI),开关量输出(DO),模拟量输入(AI),模拟量输出(AO)等模块。
