The Bacnet driver uses the standard NiagaraAX network architecture. See “About Network architecture” in the Drivers Guide for more details. However, a station’s BacnetNetwork is unique because of simultaneous support for multiple BACnet link layer types, using different BACnet communications protocols: BACnet/IP, BACnet/Ethernet, (and if QNX-based JACE host platform, BACnet MS/TP). Thus, depending on configuration, a BacnetNetwork may proxy BACnet devices that not only reside in different BACnet networks, but are also accessed using different physical ports on the host JACE controller.
