Intro to BACnet
BACnet is a communications protocol for Building Automation and Control (BAC) networks that leverage the ASHRAE, ANSI, and ISO 16484-5 standard protocol.
BACnet was designed to allow communication of building automation and control systems for applications such as heating, ventilating, and air-conditioning control (HVAC), lighting control, access control, and fire detection systems and their associated equipment.
The BACnet protocol defines a number of services that are used to communicate between building devices. The protocol services include Who-Is, I-Am, Who-Has, I-Have, which are used for Device and Object discovery. Services such as Read-Property and Write-Property are used for data sharing.
The BACnet protocol consists of a number of data link/physical layers referred to as BACnet flavours. They include BACnet IP, BACnet MSTP, BACnet ARCNET, BACnet Ethernet, BACnet IPv6, BACnet PTP, and ZigBee.
Of these flavours, BACnet IP and BACnet MSTP are the most popular with BACnet Ethernet rapidly declining. The last few are relatively rare.
Chipkin provides solutions for all flavours of BACnet including Gateways, Routers, Data Clients, Software, and Stacks.

CAS BACnet Explorer is the perfect utility for testing, debugging and discovering BACnet® networks and devices. It is great for network diagnostics and discovering who is the problem. No more pointing fingers.
CAS BACnet Explorer performs the following functions within BACnet Networks:
The BACnet Router provides stand-alone routing between BACnet/IP, BACnet Ethernet and BACnet MS/TP.
BACnet utilizes the same protocol whether it is over RS-485 Serial, Ethernet or IP. In order to interconnect between the various levels a BACnet Router is required. The FieldServer BACnet Router can easily interconnect between BACnet MS/TP, BACnet Ethernet or BACnet/IP. Interested? Read More!
