Units
An I/O Control Unit and I/O Interface Units are used to connect Expansion Racks to expand the system.
Precautions for Correct UsePrecautions for Correct Use
Attached the enclosed cover to the I/O Connecting Cable connector on the I/O Interface Unit
when it is not being used to protect it from dust.
3-5-1 Component Names
3-5-2 System Configuration
The I/O Control Unit is connected directly to the
CJ2 CPU Unit. If it is not immediately to the
right of the CPU Unit, correct operation may not
be possible.
The I/O Interface Unit is connected directly to
the Power Supply Unit. If it is not immediately to
the right of the Power Supply Unit, correct oper-
ation may not be possible.
