根據(jù)系統(tǒng)的控制要求，采用合適的設(shè)計(jì)方法來設(shè)計(jì)PLC程序。程序要以滿足系統(tǒng)控制要求為主線，逐一編寫實(shí)現(xiàn)各控制功能或各子任務(wù)的程序，逐步完善系統(tǒng)指定的功能。除此之外，程序通常還應(yīng)包括以下內(nèi)容：
1）初始化程序。在PLC上電后，一般都要做一些初始化的操作，為啟動(dòng)作必要的準(zhǔn)備，避免系統(tǒng)發(fā)生誤動(dòng)作。初始化程序的主要內(nèi)容有：對(duì)某些數(shù)據(jù)區(qū)、計(jì)數(shù)器等進(jìn)行清零，對(duì)某些數(shù)據(jù)區(qū)所需數(shù)據(jù)進(jìn)行恢復(fù)，對(duì)某些繼電器進(jìn)行置位或復(fù)位，對(duì)某些初始狀態(tài)進(jìn)行顯示等等。
2）檢測(cè)、故障診斷和顯示等程序。這些程序相對(duì)獨(dú)立，一般在程序設(shè)計(jì)基本完成時(shí)再添加。
3）保護(hù)和連鎖程序。保護(hù)和連鎖是程序中不可缺少的部分，必須認(rèn)真加以考慮。它可以避免由于非法操作而引起的控制邏輯混亂。
