The I/O numbers for Simple Motion module indicate those when the head I/O number
is set to "0H".
If it is set to other than "0H", change the I/O number according to setting of head I/O
number.
In addition, change the external inputs, external outputs, internal relays, data resisters,
and timers according to the system used.
