Hello,
I am currently working on this, initially just to read some BACnet values into an EPICS Linux IOC, though progress is slow as I'm just fitting it in around other jobs. When I inquired it seemed as if nobody had done much work on BACnet for a couple of years or more.
 
My development is following as closely as possible the work done at TRIUMF in Canada, by Rod Nussbaumer. (Rod, I hope you don't mind me mentioning you.)
 
Marty Kraimer also developed BACnet support for the javaIOC, for DESY. I believe this needs some updating to work with the latest javaIOC, but that should not be too onerous. (Marty, sorry for another name drop.)
 
Regarding the TRIUMF work, Rod has been very helpful sending me large amounts of code and answering lots of questions but I have not yet got everything working. The route is a little tortuous due to all the different tools required and my lack of knowledge, but having gone through it recently it should be less painful again. The BACnet part of the code is a modified version (0.3.10) of bacnet4linux.(http://sourceforge.net/projects/bacnet4linux/) See also, http://bacnet4linux.sourceforge.net/.
However this is now obsolete regarding further development (even the later 0.3.12 version) and replaced by the BACnet Stack project, see http://bacnet.sourceforge.net/ and http://sourceforge.net/projects/bacnet/
 
I chose to stick with Rod's method however as it provides far more than just a BACnet stack. The bacnet4linux package includes a web server which was very useful initially for checking communications on the BACnet interface. Then the browsing and selection of PVs is web based, using a Perl script to talk to a PostgresQL database. This script also generates EPICS records and EDM panels, making it much easier to change the set of PVs we want to monitor.
Let me know if you want more detail of the whole system. It could be much more complex than you need.
 
If you wished to develop EPICS BACnet support yourself, I think there are several other BACnet stacks available, but mostly commercial and mostly geared up to adding BACnet support to the remote servers, interfacing to hardware and not specifically for the client (management) side.
It depends exactly what you want to do with the BACnet support as to whether these are any use.

EPICS Colleagues,

 

Is any one currently using and/or developing EPICS support for BACnet data communication protocol? More specifically, EPICS-to-BACnet driver that is used with commercial heating and ventilation control systems.

 

Thanks,
