BACnet - A Data Communication Protocol for Building Automation and Control Networks - see bacnet.org. BACnet is a standard data communication protocol for Building Automation and Control Networks. BACnet is an open protocol, which means anyone can contribute to the standard, and anyone may use it. The only caveat is that the BACnet standard document itself is copyrighted by ASHRAE, and they sell the document to help defray costs of developing and maintaining the standard (just like IEEE or ANSI or ISO).


Our BACnet protocol stack implementation is specifically designed for the embedded BACnet appliance, using a GPL with exception license (like eCos), which means that any changes to the core code that are distributed are made available, but the BACnet library can be linked to proprietary code without it becoming licensed under the GPL. See the eCos license overview for easy to read details about this exception to the GPL. The license does not require users to release the source code of any applications that are developed with this BACnet stack - only portions of the BACnet stack that have been modified. Note that those files in this BACnet stack that are expected to be modified are licensed using the MIT License. The text of the GPL exception included in each source file is as follows:


The BACnet stack was functionally tested using VTS (Visual Test Shell), another project hosted on SourceForge, as well as various BACnet controllers, BACnet workstations, and through BACnet routers. Some versions of the BACnet stack were BTL tested.Demo BACnet Applications Using a master Makefile in the project root directory, a dozen demo applications can be created that run under Linux or Win32. Linux supports BACnet Ethernet, BACnet/IP, or ARCNET data link layer for communication, and BACnet/IP is supported under Win32. BACnet Ethernet can also be used under Win32 with the WinPcap library. Root priveleges are required to run the Ethernet or ARCNET interfaces on Linux, but are not needed to run BACnet/IP. MS/TP support under Windows or Linux using a USB to RS-485 device is a work in progress.


The demos can be compiled under Win32 using MinGW - Minimalist GNU for Windows, Borland C++, or Microsoft Visual C++, which are free command line compilers. Be sure to pick up the free patches (service packs) for the Borland C++ compiler (SP1, SP2), as well as the free turbo debugger. It is also possible to create Win32 projects using the free Visual Studio Express Edition after downloading the platform development kit for your operating system. You can also use MinGW - Minimalist GNU for Windows which comes with Code::Blocks. I frequently use Code::Blocks for compiling the unit tests using the MinGW compiler and created some Code::Block projects for some of the demos. I have also used Code::Blocks with the Borland C++ compiler and it successfully compiles and runs the code.


The BACnet stack currently implements the following services listed in the the table. We plan to add the rest of the services as we go. With the services that are implemented, you could build a BACnet device that meets the standardized profile for a BACnet Smart Sensor, BACnet Smart Actuator, or a BACnet Application Specific Controller.


The BACnet stack currently implements an example Device Object, and handles all of the ReadProperty and ReadPropertyMultiple inquiries for the required Device Object properties. The stack handles Who-Is inquiries with an I-Am, WhoHas with I-Have, and handles reject messages for services not currently supported or implemented by your device. There is built-in handling for DeviceCommunicationControl.


You can get the latest BACnet protocol stack source code using the Subversion version control system. The main development branch is at: -stack/. This has the absolute latest code and features. Anyone doing development on the BACnet protocol stack should be using this branch. The stable release tags are at: and the stable release branches are at: This matches the released version downloadable through SourceForge. Anyone doing project development using the BACnet protocol stack should be using the tags branch and an appropriate version tag.

BACstac/DN is a BACnet protocol stack designed for the development of BACnet-compliant Windows applications that run on the Microsoft .NET 6. It was designed for the development of managed code applications and has ready examples of projects for Microsoft Visual Studio.Our software team has created a BACnet library for Microsoft .NET 6 that greatly simplifies the task of developing BACnet-compliant applications. Many Building Automation and Controls manufacturers use a Cimetrics BACstac protocol stack because of our reputation for delivering high-quality software and excellent technical support. Cimetrics does the heavy lifting of testing the BACstac with all of the latest Microsoft operating systems and implementing the new Addenda approved by the BACnet Committee in a timely fashion.


At SCADA Engine we have developed software for Building Automation compatible with BACnet products sold by a large number of manufactures. Our software supports both Linux and Windows operating systems and evaluation copies are available for download.


Dear experts. By using hyper-V, I run virtual machine win 11(guest) on the real machine win10(host). I made the internal virtual switch, so the ip of guest is "179.29.32.7", the ip of host's internal virtual switch is "179.29.32.1". In guest, I run the bacnet server builted by bacnet stack and in host, I want to send and receive bacnet data by using VTS. In VTS, parameters are, "TD's port: 179.29.32.1, "IUT's port: 179.29.32.7". When I send "whois", IUT doesn't respond anything. Could you help me...

Is there documentation of any kind about the various pieces of the VTS project/solution? I have finally gotten things to build using VS 2015 and the result creates a runnable application, so far. (I haven't yet tried to run it thru its paces to see if it runs like the executable that I downloaded and have been using.) I had to edit the PTP project options and a couple of source files to get it to even compile. It wasn't difficult but I was doing things essentially blind. So, having gotten to here...

hi how can i setup DeviceObjectReference property type? it is a stuct in bacnet standard : BACnetDeviceObjectReference ::= SEQUENCE device-identifier [0] BACnetObjectIdentifier OPTIONAL, object-identifier [1] BACnetObjectIdentifier But i can't coose this type when i define a new property for an object in Device Configuration. how can i construct it with opening tag/closing tag etc? this property type is used by many object, sometime as simple value (example acces point, structured view) simetimes...


Thank you, I'm now working on the version 3.6.7 :-) I will be glad to help but I didn't know if I will get reaction, so I kept it short. Let's get into the rabbit hole: 1) It needs to upgrade to .NET Framework 4.5 2) I get 3 errors: Error 1 error MSB8031: Building an MFC project for a non-Unicode character set is deprecated. You must change the project property to Unicode or download an additional library. See =286820 for more information. C:\Program Files...


I still can't commit, or log in to do the full release. I WAS able to upload my build. I didn't mark it as "official" pending checkin, but you can get it by clicking on the "Files" tab, selecting VTS 3.x, selecting VTS 3.6.7, and download the ZIP.


I need to create a bacnet client . developing the client in python using bacpypes. how to send and receive packets from VTS to bacpypes using VTS as a device simulator ? Testing using VTS simulator and using wireshark for network monitoring. PC1: running bacpypes based bacnet client and wireshark . PC2: running VTS bacnet simulator and wireshark. both pc1 and pc2 connected to same network and bacpypes and VTs connected to same port. 1) sending 'whois' from bacpypes in PC1 - packet received in PC2...
