Unit Installation Section 3-2
Note When installing several CS-series CPU Bus Units at the same time, a total of
16 CS-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
Controller Link Unit Models
and PLCs on page 16 . For details on current consumption of each Unit, refer
to the SYSMAC CS Series Programmable Controllers Operation Manual
(W339).
The following table provides an example of current consumption
Example: Using the C200HW-PA204 Power Supply Unit supplying a maxi-
mum current of 4.6 A (5 V) and maximum power of 30 W.

The Unit can be mounted to the 2/3/5/8/10
slots shown in the diagram on the right.
