S4IS BACnet N2 Integration

Bridging Legacy Metasys® N2 Networks to Open BACnet Systems

BACnet S4 N2 Integration Appliance

S4IS Network Appliance

The S4IS BACnet-N2 integration offers flexibility and cost savings when integrating legacy Metasys® N2 networks to Open BACnet Systems.

The BACnet-N2 Integration avoids, or defers, costly
replacement or re-engineering of existing devices on
legacy Metasys® N2 buses.

Typical use cases would be to bring data from the
Metasys® N2 network into BACnet-based enterprise
applications, energy management applications, or adding best of breed BACnet global controllers and Operator Workstations from any BACnet manufacturer to legacy Metasys® installations.

Why This Solution?

  • Secure
    Follows Cybersecurity best practices.
  • Simple
    Streamlined UI makes configuring and maintaining the
    system easy.
  • Compatible
    The BACnet protocol provides universal interoperability
    with any BACnet client or value-added application.
  • Scalable
    The setup wizard automatically discovers and configures
    the legacy N2 devices on any size N2 bus.

Key Benefits

  • Delivered as a turnkey network appliance, hosted on an
    Industrial PC
  • Standard vendor tools are used to configure N2 devices
    on each N2 bus
  • All Metasys® N2 devices are supported including N2 Open,
    System-91, VMA, Facility Explorer, MIG, Centaurus
    Integrator, and 3rd party Metasys® Compatible devices
  • Supports BACnet discovery
  • Every N2 point is fully accessible, supporting read,
    write, override, and release operations as defined by
    the N2 device
  • Retain legacy supervisory controllers, i.e. NCM, N30,
    NAE et al., and all the logic they may be performing,
    via the Upstream N2 Port
