The CS-series and CJ-series PLCs use the same architecture and are basi-
cally the same in terms of program structure (tasks), instruction system, I/O
memory, and other functionality. They do differ, however in that the CJ-series
PLCs have a different Unit structure, support different Units, do not support
Inner Boards, have different Expansion Racks, have a different I/O allocation
method, etc. These differences are outlined in the following table.
