"Network Types" is the third in our Understanding BACnet Series. The series is an overview intended for those who are encountering BACnet for the first time or those who simply wish to review basic BACnet concepts.
BACnet is a communications protocol for Building Automation and Control Networks.?One of its primary appeals is that it provides "interoperability" among different vendor's equipment. This frees the building owner from dependence on one vendor when the time comes for system expansion.
The prior video introduced the concept of Device Modeling. This video shows how, by collapsing the seven-layer Open Systems Interconnect model, BACnet adopts a four-layer model and shows how BACnet is implemented in the Application, Network, Data Link and Physical layers.
