摘要
本文提出了一种基于误差理论及PLC编程指令 ,剔除脉冲干扰信号的软件方法。以FX0N系列为例 ,编制了软件梯形图。保证了PLC采集数据的可靠性 。
A practical software method of filtering out pulse disturbing signal based on error theory and PLC's programmed instruction is presented,the software echelon chart of FX0N series is workouted and ensuring the reliability of PLC data sampling ,improving control precision of system.
