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)存的一個區(qū)?？勺x寫）交換信息等等特點。
這里的A/D中的A，多為電流，或電壓，也有為溫度。D/A中的A，多為電壓，或電流。電壓、電流變化范圍多為0～5V，0～10V，4～20mA。有的還可處理正負(fù)值的。
這里的D，小型機(jī)多為8位二進(jìn)制數(shù)，中、大型多為12位二進(jìn)制數(shù)。
A/D、D/A有單路，也有多路。多路占的輸入輸出繼電器多。
有了A/D、D/A單元，余下的處理都是數(shù)字量，這對有信息處理能力的PLC并不難。中、大型PLC處理能力更強(qiáng)，不僅可進(jìn)行數(shù)字的加、減、乘、除，還可開方，插值，還可進(jìn)行浮點運算。有的還有PID指令，可對偏差制量進(jìn)行比例、微分、積分運算，進(jìn)而產(chǎn)生相應(yīng)的輸出。計算機(jī)能算的它幾乎都能算。
這樣，用PLC實現(xiàn)模擬量控制是*可能的?？刂频膯挝恢悼尚〉?/span>212分之一的測量程值，多數(shù)也是足夠的。
PLC進(jìn)行模擬量控制，還有A/D、D/A組合在一起的單元，并可用PID或模糊控制算法實現(xiàn)控制，可得到很高的控制質(zhì)量。
用PLC進(jìn)行模擬量控制的好處是，在進(jìn)行模擬量控制的同時，開關(guān)量也可控制。這個優(yōu)點是別的控制器所不具備的，或控制的實現(xiàn)不如PLC方便。
當(dāng)然，若純?yōu)槟M量的系統(tǒng)，用PLC可能在性能價格比上不如用調(diào)節(jié)器。這也是應(yīng)當(dāng)看到的。
