PC Configuration
The basic PC configuration consists of two types of Rack: a CPU Rack and Ex-
pansion I/O Racks. The Expansion I/O Racks are not a required part of the basic
system. They are used to increase the number of I/O points. An illustration of
these Racks is provided in 3-3 IR Area. A third type of Rack, called a Slave Rack,
can be used when the PC is provided with a Remote I/O System.

CPU Racks
A C200HX/HG/HE CPU Rack consists of three components: (1) The CPU Back-
plane, to which the CPU Unit and other Units are mounted. (2) The CPU Unit,
which executes the program and controls the PC. (3) Other Units, such as I/O
Units, Special I/O Units, and Link Units, which provide the physical I/O terminals
corresponding to I/O points.

which executes the program and controls the PC. (3) Other Units, such as I/O
Units, Special I/O Units, and Link Units, which provide the physical I/O terminals
corresponding to I/O points.
A C200HX/HG/HE CPU Rack can be used alone or it can be connected to other
Racks to provide additional I/O points. The CPU Rack provides three, five, eight,
or ten slots to which these other Units can be mounted depending on the back-
plane used.

plane used.
Expansion I/O Racks
An Expansion I/O Rack can be thought of as an extension of the PC because it
provides additional slots to which other Units can be mounted. It is built onto an
Expansion I/O Backplane to which a Power Supply and up to ten other Units are
mounted.

mounted.
An Expansion I/O Rack is always connected to the CPU Unit via the connectors
on the Backplanes, allowing communication between the two Racks. Up to three
Expansion I/O Racks (two with the C200HE PCs) can be connected in series to
the CPU Rack.
on the Backplanes, allowing communication between the two Racks. Up to three
Expansion I/O Racks (two with the C200HE PCs) can be connected in series to
the CPU Rack.
Unit Mounting Position
Only I/O Units and Special I/O Units can be mounted to Slave Racks. All I/O
Units, Special I/O Units, Group-2 High-density I/O Units, Remote I/O Master
Units, PC and Host Link Units, can be mounted to any slot on all other Racks.
Interrupt Input Units must be mounted to Backplanes with the “-V2” suffix on the
model number.

Refer to the C200HX/HG/HE Installation Guide for details about which slots can
be used for which Units and other details about PC configuration. The way in
which I/O points on Units are allocated in memory is described in 3-3 IR Area.
