■ CS1 CPU Rack
A CS1 CPU Rack consists of a CPU Unit, Power Supply Unit, and Configuration Units (Basic I/O Units, Special I/O Units, and CPU Bus
Units).

● Types of Units
In the SYSMAC CS Series, Units are classified into the following three types. The number of Racks differs depending on the type.

Description
Units with contact inputs and contact
outputs.
Special I/O Units provide more
advanced functions than do Basic I/O
Units, including I/O other than contact
inputs and contact outputs.
Examples of Special I/O Units are
Analog I/O Units and High-speed
Counter Units. They differ from CPU
Bus Units (including Network
Communications Units) in having a
smaller area for exchanging data with
the CPU Unit.
CPU Bus Units exchange data with
the CPU Unit via the CPU Bus.
Examples of CPU Bus Units are
Network Communications Units and
Serial Communications Units.
They differ from Special I/O Units in
having a larger area for exchanging
data with the CPU Unit.
