INTRODUCTION
(2) Replacement method without changing the I/O address of the A0J2HCPU
(a) Replacing the A0J2-E56
The A0J2HCPU has I/O points consisting of 32 input points in the first half and 32 output points in the
last half for each I/O module.
When replacing with the building block type, replacement with the same I/O address is possible by
selecting a terminal block module to keep an equivalent wiring method and arranging in the order of
two input modules and two output modules.
(b) Replacing the A0J2-E32, A0J2-E24, and special module
As the input, output, and special modules are 64 point blocks,32 points will become vacant when
replacing with Q series I/O.
When replacing with the building block type, replacement with the same I/O address is possible by
arranging the modules in actual usage mode and setting the head address of each slot using the I/O
assignment of the parameter.
