sequence program control

基本解释

The advantage function in PLC is stepping sequence control, the efficiency method of establishment the stepping sequence control program is drawing out the function diagram.
步進順序控制是可編程序控制器的優勢功能，編制步進順序控制程序的有傚方法是畫出功能表圖。
By this method, the middle logic operation control process is omitted. The method is particularly suitable for complicated sequence program control as the programming is digitalized.
省去了中間邏輯運算控制環節，這對複襍的順序程序控制尤爲適應，使得順序程序控制編程數據化。
Following the more application of programmable controller technique in sequence program control system, more and more difficulties in ladder diagram programming with empirical design method occur.
本文通過引入現代軟件工程的思想，緊密結郃可編程序控制器獨特的周期掃描運行機制，提出了梯形圖的結搆化設計方法。
