BACstac/32 - BACnet protocol stack for 32-bit embedded controllers (B1140)

This product is only available upon request. Contact us for a quote.


  • The Cimetrics BACstac (BACnet protocol stack) saves man-years of development when your company needs to create a BACnet solution for a 32-bit and 64-bit embedded platform.

    Implementation of the BACnet standard is a challenging assignment for even the most skilled computer programmers.  The differences between BACnet and traditional IT protocols can lead to a significant learning curve when starting from scratch.

    Our software team has created a set of BACnet libraries which greatly simplify the task of creating BACnet-compliant products.  Even the largest companies in the HVAC industry use our code because it is a very complex and time-consuming task keeping up with the ongoing changes that are taking place in the BACnet standard.  Numerous BACstac-based products are now BTL listed..

    This is a BACnet protocol stack, a BACnet development kit designed for the creation of BACnet-compliant applications that run on 32-bit and 64-bit embedded platforms. Complete C-language source code is included.  The customer is responsible for porting the BACnet software to the target platform.

    New in V7.2: BACstac 7.2 supports all required functionality of BACnet 2016 (protocol revision 19) for all BACnet profiles. Most optional functionality of BACnet 2016 is also supported with the following exceptions:

    - Network Security (Chapter 24).
    - Support of IPv6 (ANNEX U).
    - Virtual Terminal services.
    - Slave Proxy functionality.
    - Extended MS/TP Frames (Addendum 135-2012an).

    This release has added two new addenda: 135-2012am and 135-2012ba.

    Supports following profiles: B-XAWS, B-AWS, B-OWS, B-OD, B-ALSWS, B-LSWS, B-LSAP, B-AACWS, B-ACWS, B-ACSD, B-BC, B-AAC, B-ASC, B-SA, B-SS, B-ALSC, B-LSC, B-AACC, B-ACC, B-RTR, B-GW, BBBMD, B-ACDC, and B-ACCR.

    Data links: BACnet/IP with Foreign Device and BBMD support, Ethernet (IEEE 802.3), MS/TP, PTP.

    BACnet routing: This product supports BACnet routing functionality and the creation of multi-device gateways.

    Operating system requirements: The target platform must support threads (tasks), semaphores, recursive mutexes, dynamic memory allocation, time, persistent storage (for configuration data), and the required network interfaces; please refer to the Porting Guide for more information. BACstac 7.2 has been verified on Debian GNU/Linux 8.0 (Jessie), Debian GNU/Linux 9.0 (Stretch), Ubuntu 16.04 (Xenial), Ubuntu 18.04 (Bionic), STM32F7 (ARM Cortex M7 + FreeRTOS + LWIP).

    Development tools: For Linux-based target platforms, supported development environments are gcc version4.1 or later, Perl 5.6 or later (5.8 is recommended). For lower-end ARM Cortex M microprocessors (M0 to M4) suggest using uBACstac,
    BACstac/32 is good for Cortex M7. ARM Cortex family includes very powerful Cortex-A series, which run  Linux and are perfectly supported by both BACstac/32 and BACstac/Linux.

    Code provided: Example programs, unit tests, makefiles for both, and complete C-language source code.

    Documentation provided: User's Guide, Porting Guide, and Programmers Reference.

    Customers that want to develop a BACnet-compliant device that will run on Microsoft Windows should also consider the B1091 BACnet Software for Windows (source code).
