Chapter 2: Overview

Genius Dual Busses are typically deployed in applications such as that diagrammed in Figure
1, where high availability, ability to withstand faults in the I/O network and in the PLC CPU
system, is required.
In the RX3i environment, Genius devices must be interfaced via the Genius Communications
Module (GCG001), which then communicates over PROFINET with the host PLC.
GCG001 supports several different Genius head-ends, allowing other types of I/O rack to be
attached to the Genius bus.
