3.2用于模擬量控制
模擬量,如電流、電壓、溫度、壓力等等,它的大小是連續(xù)變化的。工業(yè)生產(chǎn),特別是連續(xù)型生產(chǎn)過程,常要對這些物理量進(jìn)行控制。
作為一種工業(yè)控制電子裝置,PLC若不能對這些量進(jìn)行控制,那是一大不足。為此,各PLC廠家都在這方面進(jìn)行大量的開發(fā)。目前,不僅大型、中型機(jī)可以進(jìn)行模擬量控制,就是小型機(jī),也能進(jìn)行這樣的控制。
PLC進(jìn)行模擬量控制,要配置有模擬量與數(shù)字量相互轉(zhuǎn)換的A/D、D/A單元。它也是I/O單元,不過是特殊的I/O單元。
A/D單元是把外電路的模擬量,轉(zhuǎn)換成數(shù)字量,然后送入PLC。D/A單元,是把PLC的數(shù)字量轉(zhuǎn)換成模擬量,再送給外電路。
作為一種特殊的I/O單元,它仍具有I/O電路抗干擾、內(nèi)外電路隔離,與輸入輸出繼電器(或內(nèi)部繼電器,它也是PLC工作內(nèi)存的一個(gè)區(qū)。可讀寫)交換信息等等特點(diǎn)。
