The NAE/NCE is a component of the Metasys® system. In terms of the BACnet protocol, the NAEs/NCEs are building controllers and support many operator workstation services.
The NAE/NCE can monitor and supervise a network of BACnet and non BACnet devices. An operator views the data on a web browser that is logged on to the web-enabled user interface of an NAE/NCE. As a building controller, other BACnet devices on the network can read and write to the BACnet objects within an NAE/NCE.
