1．PLC程序設(shè)計(jì)的一般步驟
(1)若所采用的PLC自帶有程序，應(yīng)該詳細(xì)了解程序已有的功能和對(duì)現(xiàn)有需求的滿足程度和可修改性。盡量采用PLC自帶的程序。
(2)將所有與PLC相關(guān)的輸入信號(hào)(按鈕、行程開關(guān)、速度及溫度等傳感器)，輸出信號(hào)(接觸器、電磁閥、信號(hào)燈等)分別列表，并按PLC內(nèi)部接口范圍，給每個(gè)信號(hào)分配一個(gè)確定的編號(hào)。
(3)詳細(xì)了解生產(chǎn)工藝和設(shè)備對(duì)控制系統(tǒng)的要求。畫出系統(tǒng)各個(gè)功能過程的工作循環(huán)圖或流程圖、功能圖及有關(guān)信號(hào)的時(shí)序圖。
(4)按照PLC程序語言的要求設(shè)計(jì)梯形圖或編寫程序清單。梯形圖上的文字符號(hào)應(yīng)按現(xiàn)場信號(hào)與PLC內(nèi)部接口對(duì)照表的規(guī)定標(biāo)注。
2．PLC程序設(shè)計(jì)的一般原則
(1)保證人身與設(shè)備安全的設(shè)計(jì)永遠(yuǎn)都不是多余的。
(2)PLC程序的安全設(shè)計(jì)，并不代表硬件的安全保護(hù)可以省略。
(3)了解PLC自身的特點(diǎn)。
(4)設(shè)計(jì)調(diào)試點(diǎn)易于調(diào)試。
(5)模塊化設(shè)計(jì)。
(6)盡量減少程序量。
(7)全面的注釋，便于維修。
