3.3 Specifications of input/output signals with CPU module
3.3.1 List of input/output signals with CPU module
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.
