描述了AISD62/AISD62E/AISD62D型高速计数模块的规格、处理和编程情况，这些模块与MELSEC-A系列CPU模块一起工作。
AISD62、AISD62E与AISD62D是分别为DC输入漏型输出型、DC输入源型输出型及差分输入漏型输出型计数模块。最大计数速度为lOOkpps(AISD62(E))或200kpps(AISD62D)。
AISD62 (E/D)对单相与2相脉冲输入进行计数时，如下所示：
单相脉冲输入乘以一：在脉冲的上升沿或下降沿计数
单相脉冲输入乘以二：在脉冲的上升沿与下降沿计数
2相脉冲输入乘以一：在A相脉冲的上升沿或下降沿计数
2相脉冲输入乘以二：在A相脉冲的的上升沿与下降沿计数
2相脉冲输入乘以四：在A相与B相脉冲的上升沿与下降沿计数
