What is BACnet architecture?

BACnet consists of a collapsed architecture that corresponds to four layers of the Open Systems Interconnection (OSI) model. The seven layer reference model is an international standard for conceptualizing network communication protocols and is widely used as the basis of many data communications standards.

How do you secure BACnet?

For devices that don’t implement BACnet/WS or devices with minimal memory where it is not possible to implement BACnet/WS with TLS or BACnet Network Security, a separate device like an IP router implementing VPN can provide security.

Which are the special features of BACnet?

BACnet provides a way to convey data including, but not limited to: hardware binary input and output values; hardware analog input and output values; software binary and analog values; schedule information; alarm and event information; files; and control logic.

What is BACnet used for?

BACnet is “a data communication protocol for building automation and control networks.” A data communication protocol is a set of rules governing the exchange of data over a computer network that covers everything from what kind of cable to use to how to form a particular request or command in a standard way.

What is the function of BACnet?

BACnet is a standard data communication protocol that enables interoperability between different building systems and devices in building automation and control applications.

What is the BACnet architecture?

The BACnet architecture is predominately limited to HVAC, lighting controls, and gateways. BACnet emphasizes efficient, lightweight communication and is optimized for small networks, small inter-networks, and short messages. BACnet consists of a collapsed architecture that corresponds to four layers of the Open Systems Interconnection (OSI) model.

What is BACnet secure connect?

A Secure Data Communication Protocol for Building Automation and Control Networks BACnet Secure Connect (BACnet/SC) is an addendum to the existing BACnet specification and utilizes the TLS protocol to authenticate devices on your building automation network and encrypt their communication.

How does BACnet/SC work?

Encryption: All of the information going through the BACnet/SC network is end-to-end encrypted, preventing bad actors from intercepting and decoding traffic. This prevents hackers from altering system performance and operation.

What is the BACnet Testing Laboratory?

The method that the American Society of Heating and Air-Conditioning Engineers chose to achieve this was through the BTL or BACnet Testing Laboratory. The BTL created a series of listings that define the objects, properties, and functionality that a device can support.
