BACnet Protocol Stack BACstac 7.2

BACnet Protocol Stack BACstac 7.2

July 09, 2019

Cimetrics now has a new version of the BACnet protocol stack: BACstac 7.2. The Cimetrics BACstac saves man-years of development when your company needs to create a BACnet solution!

BACstac software was the first third-party BACnet implementation in the industry and is now the leading third-party BACnet protocol stack used by many major brands in the HVAC and lighting controls industries worldwide. We have been developing BACnet Stack BACstac for more than 20 years and helped customers all over the world to implement BACnet in their products. Cimetrics has been a significant contributor to the design of the BACnet network protocol (ASHRAE Standard 135) and the BACnet test standard (ASHRAE Standard 135.1). In 2000, Mr. Butler, Cimetrics CTO, established the BACnet Testing Laboratories for the BACnet Manufacturers Association (now BACnet International) and managed its product testing program for six years. So as you can see, we know BACnet as nobody else and know how much work it takes to implement.

Our software team has created a set of BACnet libraries which greatly simplifies the task of interfacing to BACnet. 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 committees. For example, many hundreds of protocol modifications, requirements, and enhancements have taken place in just the past year. By keeping track of those and implementing changes we typically save man-years of software development time EVERY YEAR!

The BACstac products include over 30 code examples that you can use to speed development.

Scalability:
- One BACnet device in the BACstac database can contain thousands of BACnet objects.
- A BACstac gateway application can emulate thousands of BACnet devices.
- A BACstac-based client application can poll over 10,000 BACnet devices in parallel.

Check out the different versions of BACstac Cimetrics offers.*

*The features of BACstac 7.2 differ from the features of uBACstac (B1150) and BACstac/DN (B1070, B1080).
