Is it possible to implement BACnet using AD's line of PLCs?

If it is a serial protocol, I bet you could implement it using a Basic Co-Processor.
Sad, but I never heard of the protocol http://forum1.automationdirect.com/board/eek.gif . I found the organization's website and it appears to be a well established protocol for Building Automation.
I wonder if elevmike knows anything about it!

Did you find a solution, DuctSoup?
I have to provide a BACNet connection to a DL06. I'm guessing that a buy either an ECOM or a a D0-DCM and a black box. I really don't want to use the DCM if I don't have to -- I'm hoping that I'm done with serial MODBUS.

Paul,
For the small PLCs like the DL06 at least it seems BACnet is not supported. Our solution was to use a Raspberry Pi and some custom gcc code as a protocol translator.
If you want any of the details just ask.
Good luck, Craig

Real Time Automation has BACnet gateways to various protocols. While we have not used the BACnet devices we have used other RTA Gateways. The setup is dirt simple. The price is well worth the time you would spend trying to put together something on your own.

Looks interesting. What do they cost roughly?

On the order of $300 - $400 if I remember correctly. Just call, you may end up tlking to the president of the company.

I love those kinds of places as they take what they do very seriously and crank out a solid product. Control Solutions offers something similar that holds up very well in our heavy industrial setting.
In this case I just couldn't bring myself to spend that kind of change on something so simple when it could technically cost under $100. At the time I also hadn't coded anything in C for over 20 years and had never wrote an application for contemporary Linux so it was a chance to brush up. With open source BACnet and MODBUS stacks available it didn't take much to glue them together. Originally the code was developed on a SheevaPlug but we switched to the $35 RasPi (we get them from Newark) mostly because setting up the Marvel development platform is a complete pain in the neck and, they kept making the devices more and more capable and expensive. All that extra hardware wasn't necessary for this purpose.
