Figure 2: RX3i Genius Dual Bus Interfaced to RX3i via Genius Gateway Modules
(GCG001)
A typical system consists of at least two RX3i racks, with the following components in each
rack:
•
One or more power supplies.
•
One PLC CPU module (IC695CPE330 or equivalent).
•
Two RMX reflective memory exchange modules (for CPU synchronization)
.
•
Fiber optic cables for the RMX modules.
•
One or more PROFINET Controller modules.
Additionally, the system will require the following items to interface with each dual Genius
I/O network:
•
Four Genius Communications Gateway modules (two associated with the Primary
PLC interface and two with the Secondary PLC interface).
•
Cat5 or 6 Ethernet Cables to interconnect the Gateways with the PROFINET
Controllers.
•
Optional - interposing Ethernet switches that may be installed to provide additional
MRP ring functionality.
If a CPE400 is used, the RMX links are replaced with LAN3 links.
