CAS BACnet Stack

Chipkin’s BACnet Stack (CAS BACnet Stack) is an application layer BACnet library for embedded systems and application development. The BACnet Stack can function both as a server (Field Device, etc…) or as a client (HMI, etc…)

The BACnet Stack is a transport layer independent library, making it easy to use with any transport layer such as MSTP, IP, Ethernet and even PTP and ARCnet. By giving you control of the transport layer, you can optimize bandwidth and performance by exploiting resources at your disposal such as mutli-threading and multiple simultaneous connections.

The BACnet Stack is particularly well-suited to most contemporary programming styles as the API uses XML to transfer requests for packet building as well as for handling back-parsed packets.

The CAS BACnet Stack can save man-years of development when your company needs to add BACnet to their products.

Features
  • OS independent (tested with WinCE/Win32/Win64, Linux, FreeRTOS)
  • Transport layer independent
  • Client/Server functionality
  • Example code for both client/server on a variety of transport layers; TCP/IP, Ethernet (IEEE 802.3), RS232 (EIA-232, Serial) and RS485 (EIA-485, MSTP)
  • XML strings for all incoming/outgoing messages
  • Build with modern coding practices and design patterns.

OSI Model

The CAS BACnet stack implements the Application, Presentation and Session layers of the OSI model. The BACnet stack is transport layer independent. This allows you to use any transport layer that you want to including; TCP/IP, Ethernet (IEEE 802.3), RS232 (EIA-232, Serial) and RS485 (EIA-485, MSTP), PTP or ARCnet.

Licensing and Price

The CAS BACnet stack is royalty free, and free of charge.

Instead of charging for the BACnet Stack, we charge for 100 hours of support to help you integrate the BACnet stack in to your device or application.

Another option that is highly recommended is sending one of our engineers to work along side your engineers at your offices, for the cost of air travel and accommodation.

Communication Interfaces

The CAS BACnet stack is transport layer independent and can be implemented on top of any transport layer you provide. We have working examples of the CAS BACnet stack working with IP, Ethernet, RS232 and RS485.
