Abstract: A building management system network interface device including a processing circuit, which includes a device interface and a network interface. The device interface is configured to provide a serial communication link between the network interface device and an HVAC device. The network interface is configured to communicate with an external network, and to receive data values from the processing circuit. The device interface is configured to populate one or more attributes of an equipment object with the data values. The network interface is configured to map the attributes of the equipment object to individual data objects, and to write the attributes to the mapped individual data objects. The processing circuit is further configured to execute control logic to control the operation of the HVAC device based in part on the data received from the device and one or more commands received from the external network.
