The Cimetrics BACstac (BACnet protocol stack) saves man-years of development when your company needs to create a BACnet solution for Linux OS.
Implementation of the BACnet standard is a challenging assignment for even the most skilled computer programmers. The 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 simplifies the task of creating BACnet-compliant products. 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 standard. Numerous BACstac-based products are now BTL listed.
