Communicating signals between QD72P3C3 and each module

The following shows the outline of the signal communication between the QD72P3C3 and
programmable controller CPU, peripheral (GX Configurator-PT), and drive unit. (A
peripheral is connected to the programmable controller CPU, and communicates signals
with the QD72P3C3 via the programmable controller CPU.)
For details of each I/O signals, refer to CHAPTER 3.
