The networking protocol options supported by the CG/CV and FEC equipment controller families include:

  • BACnet MS/TP: Applies to installations where a high-speed, industry-standard, open communication protocol is preferred.
  • BACnet/SC: Applies to installations where Ethernet cabling with improved cybersecurity and network infrastructure integrity is preferred. This communication protocol is available with the Metasys CVE, CGE, VMA1930, and FAC4911 controllers. Metasys supports the following networking topologies, each with their own cost and network resiliency characteristics:
    • Star
    • Daisy chain
    • Ring, using Media Redundancy Protocol (MRP) and selected Cisco® IE switches
  • BACnet/IP: Applies to installations where Ethernet cabling with a high-speed, industry-standard open communication protocol is preferred. This communication protocol is available with the Metasys CVE, CGE, VMA1930, and FAC4911 controllers. Metasys supports the following IP networking topologies, each with their own cost and network resiliency characteristics:
    • Star
    • Daisy chain
    • Ring, using Media Redundancy Protocol (MRP) and selected Cisco® IE switches
  • Wireless ZFR: Applies to installations where a less invasive, more flexible networking alternative to hard wiring is preferred or is more affordable.
  • N2: Applies to legacy Metasys system installations that have equipment controllers added, where they can share the same N2 bus as legacy Metasys controllers, such as UNTs, VMA14xx, and DX-9100s.
