BACnet International and BTL Implement Protocol Revision Requirement
Testing and Listing Policy to Keep Pace with BACnet Standard Advancements
GA (PRWEB) June 13, 2012 - BACnet International and the BACnet Testing
Laboratories (BTL) announced today that they will be implementing a
minimum protocol revision requirement for testing of products that are
applying for BTL Listing. As the BACnet standard advances, the BTL
wants products displaying the BTL Mark to advance with it to offer
optimal interoperability between BACnet-based devices. This policy is
being coordinated on a global basis and will be instituted starting in
2014 giving vendors more than a year to prepare for this change.
Detailed information about the BTL and the policy change can be found
The new policy will go into effect starting on Jan 1, 2014. All products and devices that are already BTL listed will be able to keep their current listing. When a listed product is submitted for re-testing due to modification made to the product, the product will have to meet the minimum protocol revision requirement in effect at that time. Products that are submitted to the lab before the minimum protocol revision is updated will be allowed to be tested at the protocol revision that was in effect when they made their testing application.
Duffy O’Craven, Manager of the BACnet Testing Laboratories (BTL), discussed the new policy. “The periodic policy changes are a necessary and good thing for the BACnet community. The reasoning is that the BACnet standard is intended to be a single standard, but over time the small differences in protocol revisions accumulate, and those differences can hamper compatibility. This is BACnet International’s endeavor to limit the number of protocol revisions in practical use at any given time.” Mr. O’Craven added, “As the standard moves forward, it is important that products also advance to ensure that the user community gets the benefit of the newer features of the protocol.”
Andy McMillan, President of BACnet International and General Manager of Philips Teletrol, commented on the protocol revision, “The last few years have seen a steady increase in both the number of BACnet-based products and the capabilities of those products. To ensure device interoperability and maximum value for end users we need to continually adjust the protocol requirements for testing.” He added, “The BTL has devised a plan that will help advance the standard in a manageable way for manufacturers."
