在很多工厂应用中，需要对现场采集过来的脉冲信号进行计数。如果使用专用脉冲计数模块，可以采集到高速脉冲信号。但是脉冲模块价格昂贵，在一些采集低速脉冲信号的场合其实可以使用普通的开关量输入模块代替脉冲计数模块。这样可以降低系统成套费用和系统的复杂程度，也提高了系统的可维护性。如果使用普通开关量输入模块代替脉冲计数模块，就存在一个问题:普通开关量输入模块采集脉冲信号的速度的极限是多少？存在哪些制约条件？以下将以AB公司的ControlLogix 1756系列PLC系统为基础，就这个问题谈一些分析存储器是具有“记忆”功能的设备，它用具有两种稳定状态的物理器件来表示二进制数码“0”和“1”，这种器件称为记忆元件或记忆单元。记忆元件可以是磁芯，半导体触发器、MOS电路或电容器等…
