PLC的基本組成

　　1. 中央處理器

　　中央處理器(CPU)由控制器、運(yùn)算器和寄存器組成并集成在一個(gè)芯片內(nèi)。CPU通過數(shù)據(jù)總線總線、地址總線、控制總線和電源總線與存儲(chǔ)器、輸入輸出接口、編程器和電源相連接。

　　小型PLC的CPU采用8位或16位微處理器或單片機(jī)，如8031、M68000等，這類芯片價(jià)格很低;中型PLC的CPU采用16位或32位 微處理器或單片機(jī)，如8086、96系列單片機(jī)等，這類芯片主要特點(diǎn)是集成度高、運(yùn)算速度快且可靠性高;而大型PLC則需采用高速位片式微處理器。

　　CPU按照PLC內(nèi)系統(tǒng)程序賦予的功能指揮PLC控制系統(tǒng)完成各項(xiàng)工作任務(wù)。
