描述
CPU模塊相當(dāng)于人的大腦和心臟，它不斷地采集輸入信號，執(zhí)行用戶程序，刷新系統(tǒng)的輸出；存儲器用來儲存程序和數(shù)據(jù)。
1．CPU芯片
CPU模塊主要由CPU芯片和存儲器組成。PLC使用以下幾類CPU芯片：
(1)通用微處理器，如Intel公司的8086，80186到Pentium系列芯片；
(2)單片微處理器(單片機)，如Intel公司的MCS51／96系列單片機；
(3)位片式微處理器，如AMD2900系列位片式微處理器。
2．存儲器
PLC的存儲器分為系統(tǒng)程序存儲器和用戶程序存儲器。系統(tǒng)程序相當(dāng)于個人計算機的操作系統(tǒng)，它使PLC具有基本的智能，能夠完成PLC設(shè)計者規(guī)定的各種工作。系統(tǒng)程序由PLC生產(chǎn)廠家設(shè)計并固化在ROM內(nèi)，用戶不能直接讀取。PLC的用戶程序由用戶設(shè)計，它決定了PLC的輸入信號與輸出信號之間的具體關(guān)系。用戶程序存儲器的容量一般以字(每個字由16位二進制數(shù)組成)為單位，三菱的FX系列PLC將用戶程序存儲器的單位稱為步(Step，即字)。小型PLC的用戶程序存儲器容量在lK字左右，大型PLC的用戶程序存儲器容量可達數(shù)M(兆)字。
