*1: A program used before replacement can be utilized by setting the start I/O signal numbers of the modules mounted to the right
of the QD62-H02 so that they can be the same with that of the module before replacement.
(Set the start number at "Start XY" of the I/O assignment tab. The number of occupied points of the QD62-H02 cannot be changed.)
*2: The rise/fall time of a pulse affects the counting speed. Countable counting speeds are as follows.
Counting a pulse whose rise/fall time is long may result in a miscount.
