Building Automation and Control Networks.<\/p>\n

BACnet.<\/p>\n

An industry staple that continues to revolutionize both building automation and the world of HVAC. Is it any wonder that more and more suppliers and distributors are broadening their spheres to keep up with the demand from customers? And for good reason!<\/p>\n

So how did BACnet get started?<\/h2>\n

During the summer of 1987, ASHRAE had an inaugural committee meeting* where the topic of conversation was focused on creating a standard open protocol for the building automation industry. The committee was comprised of three distinct working groups: Data Type and Attribute Working Group, Primitive Data Format Working Group, and Application Services Working Group. They all worked together to create a consensus regarding a standard for BACnet. And in 1995, they achieved their goal by creating ASHRAE\/ANSI Standard 135.<\/p>\n

As an important note\u2014we of course can\u2019t forget the \u201cFather of BACnet\u201d himself, Michael Newman, whose dedication and commitment to what BACnet could one day become truly helped it reach new heights.<\/em><\/p>\n

But what really makes BACnet so great? Well, as ASHRAE puts it, \u201cBACnet provides a comprehensive set of messages for conveying encoded binary, analog, and alphanumeric data between devices including, but not limited to:<\/p>\n

(a) hardware binary input and output values,
(b) hardware analog input and output values,
(c) software binary and analog values,
(d) text string values,
(e) schedule information,
(f) alarm and event information,
(g) files, and
(h) control logic.<\/p>\n

It models each building automation and control computer as a collection of data structures called objects, the properties of which represent various aspects of the hardware, software, and operation of the device. These objects provide a means of identifying and accessing information without requiring knowledge of the details of the device’s internal design or configuration.\u201d\u00a0(Read more about Standard 135-2016 here<\/a>.)<\/p>\n

Another interesting aspect of BACnet is that it\u2019s not proprietary information. So because it\u2019s an open protocol system, anyone can write it. It just needs to follow basic rules, commands, and of course industry standards. Talk about an easily accessible feat of technology that the industry is lucky to have!<\/p>\n

BTL Certification<\/h2>\n

What is BACnet Testing Laboratories (BTL)? The entity was developed and is also operated by BACnet International. They support interoperability testing and compliance testing activities when it comes to all things BACnet, while also overseeing the global product certification program and administering the BTL Working Group (BTL-WG).<\/p>\n

Some of the responsibilities of the BTL as defined by them are as follows:<\/p>\n
