Understanding BACnet Part 2: Device Modeling

"Device Modeling" is the second 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. This video is an overview of BACnet device modeling. It presents an example of Objects, Properties and Services. www.ccontrols.com

Nice to see a DEOS controller in this video. I didn't think they were that popular

Thank You

Now if we could get you to stop letting engineers think that bacnet can do anything. They write very complicated sequences of operation and then buy bacnet only equipment not realizing that we cant control the unit with bacnet. Just give the units some setpoints and thats all. I am so tired of explaining this to commissioning agents. CX says, start the fan... I cant... CX says start a compressor....I cant..... CX says give the unit a fake outdoor air temp ...I cant.... CX says change the speed of the heat wheel....I cant... So until you get equipment manufacturers to allow us to have control of a unit as if we were hard wired to it then the only opinion of bacnet I can put forth is that it really sucks. I've been doing bacnet ever since it was invented and all I see it doing is killing our controller sales and causing great confusion about its capabilities, which it has very few in reality.

After watching this video series I am understanding that BACnet is just a highway of communication signal traffic, no command signal traffic allowed on it i.e. 0-10v, 4-20mA. Your comment confirms it, I think.
