摘要
从工程实际出发,介绍了PLC(可编程序控制器)控制系统中模拟量信号的采样和滤波方法,并以S7300 PLC语句表(STL)编程为例,给出了部分程序或程序流程图,并用仿真和应用实例证明了其有效性和可行性。
Based on the practical application, the sampling and filtering method of the continuous signal for PLC control systems are introduced in this paper. And the relevant programs written in STL (Statement Table List) of S7300 PLC or program flow charts are given as examples. Meanwhile emluator and practical example were used to prove its validity and feasibility.
