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，是用戶針對具體控制對象編制的程序。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。
