Power supply module
One power supply module is required to be installed
on a base module.
CPU module(s)

Special module(s)
Many types are available such as analog input/output
and communication.
A location where you install a module is called a slot.
Main Unit
A unit with a CPU module is called a main unit.
Install the power supply module in the slot on the left end of the base module and install
the CPU module(s) in the slot(s) immediately to the right of the power supply module.
Subunit
A subunit is an extension unit for accommodating additional I/O modules, and is
connected to a main unit using an optical FA bus module. Thus, a subunit has no CPU
module installed. Up to seven subunits may be connected to a main unit.
Slot Number
