BACnet protocol support

BACnet is a Data Communication Protocol for Building Automation and Control Networks. Developed under the auspices of the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), BACnet is an American national standard, a European standard, a national standard in more than 30 countries, and an ISO global standard.

CSWorks installation package includes a sample that demonstrates how a CSWorks-based solution can be integrated with a room thermostat that supports BACnet protocol.

CSWorks supports only that version of BACnet protocol that uses network for communication - BACnet/IP. Another popular version of BACnet protocol is BACnet/MSTP, which works over a serial communication. If you want CSWorks to work with BACnet/MSTP devices, you will have to use a BACnet/IP to MSTP adapter - a device that connects to the local network on one side and to a number of BACnet/MSTP devices on the other. There is a well-established market for this kind of devices and a few models to choose from. The sample mentioned above uses this kind of device to access a BACnet/MSTP thermostat.

You do not need any additional software or middleware to make your CSWorks applications talk to BACnet devices. In CSWorks LiveData Service settings, specify the ID (BACnet ID) of the Modbus device, and specify which type of input/value and address your data items should use. The BACnet/IP to MSTP adapter will route all communication to the device with the specified ID.
