System Configurations
The following figure shows an assembled C500 CPU Rack and one Expan-
sion I/O Rack. When three Expansion I/O Racks are connected to a CPU
Rack, a maximum of 512 I/O points are available. (Include the Remote I/O
Units)

Where I/O Units Can Be
Mounted
The table below summarizes the Units that can be used in the systems de-
scribed in this manual.
Special I/O Units
The number of Special I/O Units that can be used depends
upon the number of points available and the number of
points the Special I/O Unit requires.
Host Link Units
Up to one Host Link Units can be mounted. Only one
Rack-Mounting Host Link Unit can be mounted to the CPU
Rack. A CPU-Mounting Host Link Unit can also be mounted
directly to the CPU. Host Link Units cannot be mounted to
Expansion I/O Racks.
However, these Units cannot be mounted when the
SYSMAC Net Link Unit is mounted.
I/O Units
Standard I/O Units are available with 16, 32, or 64 points.
Refer to
Section 2 Description of All Components for details.
Memory Packs
RAM or ROM Packs are available. The ROM Pack requires
a separately available EPROM chip.
Remote I/O Master
Unit
Up to four Remote I/O Master Units can be mounted to both
the I/O Rack and the Expansion I/O Racks. When the
Remote I/O Unit is mounted to a Rack, a Rack number must
be set so that the CPU can identify the Remote I/O Unit.
Mount the Remote I/O Slave Unit to the leftmost position
(the I/O Interface Unit position) on the Slave Rack. For
details, refer to the C500 Operation Manual.
