This article will present BACnet resources to aid and inform the automation developer. The internet offers a wide variety of sites related to BACnet development from personal to commercial sites. Two of the more impressive, detailed websites will be the focus of this article. All the items discussed in this article will be available through links on both websites for easy access.
The first website to be profiled will be the official BACnet site, which offers a webpage specifically for the developer. The links on the developer webpage includes:
- CAS BACnet Explorer is a BACnet utility that can be used to Explore, Test, Monitor, and Debug BACnet networks. Its easy to use and free to download.
- The SCADA Engine is a commercial resource that offers software development for Client and Server applications for a variety of operating system platforms.
- BACnetSim is a portable implementation of BACnet for the developer to evaluate functionality before final large-scale implementation of the protocol.
- BACpypes is a BACnet library for the application and network layers. BACpypes were drafted in “Python” for scripting and graphical interfaces. Python is a programming language for application domains, and similar other such languages as Scheme, Java, etc.
- The Visual Test Shell (VTS) will allow the developer to evaluate BACnet device functionality in automation applications. VTS was developed by the BACnet Testing Laboratories (BTL), and often upgraded to maintain this application tool.
- The Wireshark provides the developer an open-source protocol analyzer. The site also includes protocol development and educational information for the developer as well.
The BACnet International website is the second important site for the BACnet developer. This site like the first examined site offers a page geared for the developer. The links on this webpage includes:
- BACnet Standard and Implementation guides , and through another link to the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) bookstore for these and other related publications.
- A link to an email list server called BACnet-L, which is an open list to all and provides a discussion forum for BACnet development. Note that advertising and other such activities are not allowed on the list. For a subscription to BACnet-L.
- The BACnet International Product Catalog provides the automation developer with detailed information on the most recent BACnet devices.
