Important
[Y1 to Y3], [Y18 to Y1F], [X2, X3], and [X18 to X1F] are used by the system, and cannot be
used by the user.
If these devices are used, the operation of the QD75 will not be guaranteed.
The QD75 uses 32 input points and 32 output points for exchanging data with the CPU
module.
The input/output signals when the QD75 is mounted in slot No. 0 of the main base unit
are shown below.
Device X refers to the signals input from the QD75 to the CPU module, and device Y
refers to the signals output from the CPU module to the QD75.
