A CPU Rack consists of a CPU Unit, a Power Supply Unit, a CPU Backplane,
Basic I/O Units, Special I/O Units, and CPU Bus Units. A Serial Communica-
tions Board and Memory Card are optional.
Note 1. The Backplanes required depend on which CPU Racks, Expansion I/O
Racks, and Slave Racks are used.
2. Expansion Racks cannot be connected to a 2-slot CPU Rack.
3. A maximum of four C200HS-INT01 Interrupt Input Units can be connected
to one CPU Unit.
The Expansion Racks required for the C200H CPU Units and CS-series CPU
Units are different.
• C200H Expansion I/O Racks can be connected to CPU Racks, CS-series
Expansion Racks, or other C200H Expansion I/O Racks.
• CS-series Expansion Racks can be connected to CPU Racks or other
CS-series Expansion Racks. A CS-series Expansion Rack consists of a
Power Supply Unit, a CS-series Expansion Backplane or C200H Expan-
sion I/O Backplane, a Basic I/O Unit, a Special I/O Unit, and a CS-series
CPU Bus Unit.
Note a) CS-series Expansion Racks cannot be connected after C200H
Expansion I/O Racks.
b) CS-series Basic I/O Units, CS-series Special I/O Units and CS-se-
ries CPU Bus Units cannot be mounted to C200H Expansion I/O
Racks.
c) Interrupt Input Units cannot be mounted to CS-series Expansion
Racks or C200H Expansion I/O Racks.
I/O Control Units and I/O Interface Units can be used to create systems con-
taining CS-series Long-distance Expansion Racks. Up to two series of Long-
distance Expansion Racks can be connected, each measuring up to 50 m, for
a total coverage of 100 m.
Up to 5 SYSMAC BUS Slave Racks can be connected to one SYSMAC BUS
Remote I/O Master Unit. A maximum of 5 Units, however, can be connected
to one CPU Unit.
A SYSMAC BUS Slave Rack consists of a Remote I/O Slave Unit, a Remote
I/O Slave Rack Backplane, a Basic I/O Unit, and a Special I/O Unit.
Note 1. C200H Group-2 High-density I/O Units, Interrupt Input Units, CS-series
Basic I/O Units, CS-series Special I/O Units and CS-series CPU Bus Units
cannot be mounted to SYSMAC BUS Slave Racks.
