INTRODUCTION
(2) Using the existing wiring
Although the CPU module, A0J2HCPU is replaced with the QCPU, the external wiring terminal block
attached to the existing A0J2 I/O module can be utilized to the interface module.
It allows to replace the modules without external wiring change.
Also, new wiring is unnecessary since the Q series I/O module is connected to the interface module with
the dedicated cable.
