PLC可编程控制器系统RAM存储区包括I/O映象区以及各类软设
备（例如：
逻辑线圈、数据寄存器、计时器、计数器、变址寄存器、累
加器等）存储区。
（A）I/O映象区
由于PLC投入运行后，只是在输入采样阶段才依次读入各输入
状态和数据，
在输出刷新阶段才将输出的状态和数据送至相应的外设。因
此，它需要有
一定数量的存储单元（RAM）以供存放I/O的状态和数据，这
些存储单元称
作I/O映象区。一个开关量I/O占用存储单元中的一个位（bit
）, 一个模拟
量I/O占用存储单元中的一个字（16个bit)。因此，整个I/O
映象区可看作
由开关量的I/O映象区和模拟量的I/O映象区两部分组成。
