| | BACnet International recently hosted its 25th PlugFest Interoperability Workshop, October 14th – 16th, at the University of New Hampshire’s Interoperability Laboratory. PlugFest allows participants to test the interoperability of their company’s BACnet products with other vendors in a friendly and neutral environment. Attendees can discover and fix implementation errors during PlugFest before they are found in the field. Twenty-eight companies sent 68 total attendees, consisting of 33 teams and 24 first-time attendees. | | |
Attendees also attended the educational panel discussion, “Testing, Certification, and the Future of BACnet”. The panel brought together industry experts to address key topics in BACnet testing, certification, implementation, and deployment. Through a series of targeted questions, the panelists shared their experiences, best practices, and insights into the evolving BACnet landscape. Attendees gained a deeper understanding of the importance of conformance and interoperability testing, strategies for efficient BTL testing, and the steps required for successful product submissions. The discussion also explored BACnet’s ongoing relevance, anticipated advancements, and practical solutions to implementation and deployment challenges—including datalink pain points, proprietary property integration, and BACnet/SC certificate management.
The discussion was moderated by Emily Hayes, BTL Manager, and the speaker panel included Osborne; Dave Robin, BSC Softworks; Coleman Brumley, LumenRadio; Patrice Hell, Sauter; and Chris Howard, Schneider Electric. The panel discussion is available to view in The BACnet Institute (TBI) Resource Library.

Need a refresher on our BTL Mark
Guidelines before the AHR Expo?
| | This year's AHR Expo will feature 1,104 BTL Listed Products from 121 companies, 102 of which are BACnet International Corporate Members. | | The BTL Mark provides users with confidence that a product has passed the industry standard BACnet conformance tests conducted by a recognized, independent testing organization. The BTL Mark is a mark of distinction, achieved by more than 1,460 products, that many building owners and control system designers consider a must-have to be eligible for a project. The BTL Mark is trademarked and its use is strictly regulated. Products that have been successfully tested by a Recognized BACnet Testing Organization (RBTO) and successfully received the BTL Certification are eligible to display the BTL Mark as part of the listing process. | | |
Minimum Protocol Revision
Reminder for BTL Testing
| | |
The current Minimum Protocol_Revision for BTL Testing is PR_18. It will remain the minimum Protocol Revision for BTL Testing in 2026. January 1, 2027, the Minimum Protocol_Revision for BTL Testing will become PR_23.
As stated in the BTL Testing Policies:
The minimum Protocol_Revision is determined each January 1st and is the highest Protocol_Revision which has been available in a BTL Test Plan for at least 4 years. The schedule below indicates the specifics of how this will work for the next few years.
All products that are at their Recognized BACnet Testing Organization (RBTO) and are ready to begin testing before the end of 2026, may test at Protocol_Revision (PR_18).
For general questions concerning BTL Testing, please contact Emily Hayes, BTL Manager.

BACnet Cybersecurity Course is now
available on The BACnet Institute (TBI)
| | The BACnet Cybersecurity course provides an overview of BACnet Secure Connect (BACnet/SC), focusing on its significance in enhancing the security of interoperable building automation systems. Participants will gain an understanding of how BACnet/SC differs from existing security measures, its technical aspects and its interaction with other BACnet devices. This course also addresses the cybersecurity challenges and future strategies for improving BACnet security. This course also places BACnet/SC in the context of the larger building automation cybersecurity landscape. | | |
Every month, BACnet International
will highlight a resource from
The BACnet Institute (TBI) Resource Library!
| | This month's featured TBI resource is "Guide to the Network Port Object," from BACnet International. This guide discusses the differences between hierarchical and non-hierarchical Network Port objects and the benefits of each. It dives into the changes to the Network Port object when Standard 135-2020, Addendum cc (Protocol_Revision 24) was published, and the consequences of choosing between pre and post Addendum cc Network Port objects. | | The BACnet Institute (TBI) is an online portal for BACnet-focused learning and knowledge sharing. It provides an easy path to BACnet information and learning for everyone involved with BACnet systems. The portal includes three on-demand FREE courses and over 200 resources including white papers, articles, presentations, and a community forum. TBI Resources are free, but registration for an account is required. Courses are eligible for CEUs and PDHs. | | |
