程序不僅要正確，還要可靠?？煽糠从持鳳LC程序的穩(wěn)定性，這也是對PLC程序的基本要求。

有的PLC程序，在正常的工作條件下或合法操作時能正確工作，而出現(xiàn)非正常工作條件（如臨時停電，又很快再通電）或進行非法操作（如一些按鈕不按順序按，或同時按若干按鈕）后，程序就不能正常工作了。這種程序，就不大可靠，或說不穩(wěn)定，就是不好的程序。

好的PLC程序?qū)Ψ钦９ぷ鳁l件出現(xiàn)，能予以識別，并能使其與正常條件銜接，可使程序適應(yīng)于多種情況。好的PLC程序?qū)Ψ欠ú僮髂苡枰跃芙^，且不留下“痕跡”。只接受合法操作。

聯(lián)鎖是拒絕非法操作常用的手段，繼電電路常用這個方法，PLC也可繼承這個方法。
