■ 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
Unit recognition method
No. of Units
Basic I/O Units
CS1 Basic I/O Units
C200H Basic I/O Units
Units with contact inputs and contact
outputs.
In the CS1 System, CS1
Basic I/O Units, C200H
Basic I/O Units, and
Group-2 High-density I/O
Units are identified by
their mounting positions
(Rack and slot).
The Units mounted must
not exceed the maximum
I/O capacity of the CPU
Unit.
Special I/O Units
CPU Bus Units
C200H Group-2 High-density
I/O Units
CS1 Special I/O Units C200H Special I/O Units
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.
Recognized by the CPU
Unit according to the unit
number (CS-series
Special I/O Units: 0 to 95,
C200J Special I/O Units:
0 to 9, or 0 to 15) set with
the rotary switches on the
front panel.
CS-series Special I/O
Units: 96 Units max.;
C200H Special I/O Units:
10 or 16 Units max. (From
1 to 4 unit numbers are
assigned per Unit,
depending on the model
of the Unit.)
CS1 CPU Bus Units
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.
Recognized by the CPU
Unit according to the unit
number (0 to F) set with
the rotary switch on the
front panel.
A maximum of 16 Units
can be mounted.
