System Configuration
The PLCs of the MELSEC iQ-R series are modular controllers. The CPUs are
installed on base units (sometimes referred to as racks) that can also accom-
modate a power supply and up to twelve modules.
You can expand the system by connecting extension base units to the main
base unit with a bus cable.
