The NCE provides support for the same communications protocols
as the NAE, but also offers the Input/Output (I/O) point
connectivity and direct digital control capabilities of a
Metasys Field Equipment Controller (FEC). The NCE provides a
cost-effective solution designed for central plants and large
built-up air handler applications. All NCE models provide IP
Ethernet network connectivity, the Site Management Portal UI,
and the network supervisory control functions featured on
network automation engines. Depending on the model and software
release, an NCE supports either a BACnet MS/TP Bus, an N2 Bus,
or a LonWorks network trunk. The NCE also provides built-in
support for third-party protocols, including Modbus, M-Bus, and
KNX.
Note: Starting at Release 10.1, the SNC Series Network
Controllers succeed the NCE Series of the Network
Control Engine family. For more information about
the SNC see SNC Series Network Control Engines.
