Important
[Yn1 to Yn7], and [Xn3 to Xn7] are used by the system, and cannot be used by the user.
If these devices are used, the operation of the QD70D will not be guaranteed.

The table below shows I/O signals of the QD70D.
For the QD70D I/O assignment, the first16 points and other 32 points are reserved for
free space and for intelligent function modules accordingly.
When the QD70D is installed to slot No.0 of the main base unit, device No.Xn0 is
regarded as X10. Note that, if 0 point is set for the first 16 points in the I/O assignment
setting of GX Developer, device No.Xn0 is X0 (n = 0).
