Note Although the CJ-series PLCs do not require Backplanes, the term "slot" is still
used to refer to the relative position of a Unit in the Racks. The slot number
immediately to the right of the CPU Unit is slot 1, and slot numbers increase
toward the right side of the Rack.
A CJ-series CPU Rack consists of a CPU Unit, a Power Supply Unit, various
I/O Units, and an End Cover. Up to 10 I/O Units can be connected.
(I/O Control Unit, See note.)
