Why the difference counts.
BACnet Excellence - made by MBS
There are many BACnet stacks. And there is the CS-Lab BACnet stack.
Many providers deliver code.
We deliver a solution - and a promise.
Because for us, it's not just about function, but about trust, quality and longevity.
A BACnet stack is just one part. We deliver the whole.
A product of CS-Lab GmbH
- distributed and supported by MBS
Our BACnet stack is a powerful software solution for integrating devices and systems into BACnet networks - from small field devices to complex automation systems.
The stack is being developed by CS-Lab GmbH, the service company for all aspects of data communication in building automation. CS-Lab was founded in 2012 as a spin-off of MBS GmbH. In order to be able to react flexibly to customer requirements, the software developers were transferred to the young company as part of a business transfer. This close relationship with the Krefeld-based building automation manufacturer, which has been successful on the market for over 35 years, has shaped CS-Lab through and through.
MBS takes care of sales, consulting and technical support - so you have an experienced contact person at your side and at the same time benefit from the technical depth of a specialized development partner.
What our BACnet stack does
The BACnet stack makes it possible to integrate devices and systems reliably and efficiently into BACnet networks. It supports all relevant data link layers - BACnet/IP, BACnet MS/TP and BACnet/SC - and can be used on any platform.
The Stack API provides all functions required for the implementation of all BACnet objects and BIBBs according to revision level 26.
The object functionality is implemented as a database. Mechanisms and fallbacks for obtaining values from the field are already integrated.
Thanks to its modular architecture, comprehensive documentation and simple integration, the stack shortens development times and significantly reduces effort.
Your technical advantages at a glance:
Compatible with BACnet/IP, MS/TP and BACnet/SC.
Platform-independent use.
Scalable - from control technology systems to the smallest devices (e.g. heat meters)
Implementations for various operating systems - from older Windows versions to modern Linux variants
Integrated security mechanisms.
Part of the BACnet Test Framework (BTF) - used worldwide by all accredited test laboratories for conformity testing
Always up-to-date, continuous further development.
Simple adaptation to project-specific requirements
