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.
步进顺序控制是可编程序控制器的优势功能，编制步进顺序控制程序的有效方法是画出功能表图。
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.
省去了中间逻辑运算控制环节，这对复杂的顺序程序控制尤为适应，使得顺序程序控制编程数据化。
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.
本文通过引入现代软件工程的思想，紧密结合可编程序控制器独特的周期扫描运行机制，提出了梯形图的结构化设计方法。
