工業(yè)控制中，除了用數(shù)字量信號(hào)來控制外，有時(shí)還要用模擬量信號(hào)來進(jìn)行控制。模擬量模塊有三種：模擬量輸入模塊、模擬量輸出模塊、模擬量輸入/輸出模塊。
(Ⅰ) 模擬量輸入模塊
模擬量輸入模塊又稱A/D模塊，將現(xiàn)場(chǎng)由傳感器檢測(cè)而產(chǎn)生的連續(xù)的模擬量信號(hào)轉(zhuǎn)換成PLC的CPU可以接收的數(shù)字量，一般多為12位二進(jìn)制數(shù)，數(shù)字量位數(shù)越多的模塊，分辨率就越高。
(Ⅱ) 模擬量輸出模塊
模擬量輸出模塊又稱為D/A模塊，把PLC的CPU送往模擬量輸出模塊的數(shù)字量轉(zhuǎn)換成外部設(shè)備可以接收的模擬量（電壓或電流）。模擬量輸出模塊所接收的數(shù)字信號(hào)一般多為12位二進(jìn)制數(shù)，數(shù)字量位數(shù)越多的模塊，分辨率就越高。
1.3.2 PLC的軟件組成
PLC控制系統(tǒng)的軟件主要包括系統(tǒng)軟件和用戶程序。系統(tǒng)軟件由PLC廠家固化在存儲(chǔ)器中，用于控制PLC的運(yùn)作。用戶程序由使用者編制錄入，保存在用戶存儲(chǔ)器中，用于控制外部對(duì)象的運(yùn)行。
1）、系統(tǒng)軟件

系統(tǒng)軟件包括系統(tǒng)管理程序、用戶指令解釋程序、標(biāo)準(zhǔn)程序模塊及系統(tǒng)調(diào)用。整個(gè)系統(tǒng)軟件是一個(gè)整體，它的質(zhì)量很大程度上影響了PLC的性能。通常情況下，進(jìn)一步改進(jìn)和完善系統(tǒng)軟件就可以在不增加任何設(shè)備條件下大大改善PLC的性能，使其功能越來越強(qiáng)。
2）用戶程序
PLC的程序一般由三個(gè)部分構(gòu)成：用戶程序、數(shù)據(jù)塊和參數(shù)塊。用戶程序是必選項(xiàng)，數(shù)據(jù)塊和參數(shù)塊是可選部分。
用戶程序即應(yīng)用程序，是用戶針對(duì)具體控制對(duì)象編制的程序。PLC是通過在RUN方式下，循環(huán)掃描執(zhí)行用戶程序來完成控制任務(wù)的，用戶程序決定了一個(gè)控制系統(tǒng)的功能。
一個(gè)完整的用戶程序應(yīng)當(dāng)包含一個(gè)主程序、若干子程序和若干中斷程序三大部分。
