• 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
• Optional – Connectors that provide Hand Held Monitor attachment points for each of the Genius
busses. (GE catalog number 44A736310-001-R001. Refer to Genius Hand-Held Monitor User’s Guide,
