Up to a total of four Controller Link Units for CJ-series PLCs can be connected
in a CPU Rack or a Expansion Rack. (Be sure to secure the Units with the top
and bottom sliders.)
Note When installing several CJ-series CPU Bus Units at the same time, a total of
16 CJ-series CPU Bus Units maximum may be installed.
Up to eight CS/CJ-series Controller Link Units with unit version 1.2 or later
can be connected to a single CPU Unit. When connecting multiple Controller
Link Units to the CPU Unit, consider the current consumption of the CPU Unit
and each CPU Bus Unit before selecting the Power Supply Unit. For details on
Controller Link Unit current consumption, refer to

and PLCs on page 16 . For details on current consumption of each Unit, refer
