摘要
本文针对PLC接收模拟量输入信号量值转换的计算问题,推导出PLC模拟量输入模块的模拟值与传感器测量物理量之间关系的通用计算表达式,并就具体实例情况进行了演绎。笔者得出的通用计算表达式,对于使用PLC处理模拟量的量值转换计算,对教学具有指导意义。
From the compuing problems of quantity-value transformation for received input signals of analog quantitys with PLC, a general computation expression between the analog value in the analog quantity input module of PLC and the physical quantity measured by a sensor is concluded, which is deduced into some examples. For the computation of quantity-value transformation of analog values disposed by PLCs, the concluded general computation expression has universal guiding significance.
