• The Cimetrics BACstac (BACnet protocol stack) saves man-years of development when your company needs to create a BACnet solution!

    The BACnet standard is more than 1300 page book that is a challenging assignment for even the most skilled computer programmers.  There are concepts in the HVAC and BUILDINGS INFRASTRUCTURE world that are just not taught in computer school.  These 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 that greatly simplify 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!

    And then there is Microsoft...  everyone knows that the number of operating systems released by Microsoft has increased dramatically.  If you sell applications that combine a PC using the Windows OS and BACnet then you will need to do extensive testing on Microsoft Windows - we have tested on all OS's Windows 7 and later: 32 bit and 64 bit!   By purchasing the Cimetrics BACstac solution, we do the compatibility coding and testing!  This typically saves man-years of software developer time EVERY YEAR!
