EMAIL INTERVIEW – Svetlana Lyons and Ken Sinclair
Svetlana Lyons, Project Manager, Cimetrics, Inc.
Why would anyone need a BACnet
Lyons: BACnet is the
most popular open communication protocol for building automation
systems. BACnet’s global market share has continued to rise over the
last years and no wonder more and more manufacturers want to add a
BACnet capability to their products. But implementing BACnet is not a
trivial task. The BACnet standard is more than 1000 pages long, and a
developer needs to familiarize him/herself with the BACnet protocol.
You might need to port it to multiple platforms. That’s where the
BACnet Stack comes into play.
So, the purpose of
the BACnet stack is to help developers to integrate BACnet into their
Lyons: Yes. The BACnet
stack is an implementation of the BACnet protocol for use by anyone who
wishes to give their products BACnet communication capability.
Cimetrics’ BACstac greatly simplifies the task of interfacing to
BACnet. Some of the largest companies in the HVAC industry use our code
because it is a very complex and time-consuming task of keeping up with
the ongoing changes that are taking place in the BACnet committee. For
example, plenty of protocol modifications, requirements, and
enhancements have taken place in just the past year. This typically
saves man-years of software developer time EVERY YEAR!
How long have you
been doing BACstac development?
Lyons: Since 1995 when
the BACnet was initially published. Can you believe it? Cimetrics knows
BACnet like no one else. Our CEO, Jim Lee is a founder and former
President of the BACnet Manufacturers Association (now BACnet
International), the leading open systems networking consortium in the
building automation industry. Our CTO, Jim Butler, has been an
innovator in embedded networking technology for building automation. In
2000, Mr. Butler established the BACnet Testing Laboratories for the
BACnet Manufacturers Association and managed its product testing
program for six years. So yes – we have been doing BACnet development
for over 20 years now.
What is special about
your BACnet Stack?
Lyons: Our BACnet Stack covers the broad range of operating systems from Workstations and Servers on Windows OS and Linux all the way down to simplest devices on the smallest platforms. You can see that in this chart of different versions of BACstac and their different features:
There are other
BACnet protocol stacks on the market. Why would a developer choose your
Lyons: Here are just
some features which set us apart from the rest. The BACstac products
include over 30 code examples that you can use to speed development.
- One BACnet device in the BACstac database can contain hundreds of thousands of BACnet objects.
- A BACstac gateway application can emulate thousands of BACnet devices.
- A BACstac-based client application can poll over 10,000 BACnet devices in parallel.
- BACstac has been used by many companies and manufacturers, and it’s been thoroughly tested in the field for many years.
Modern Product Development:
- BACstac development is feedback driven – we work closely with customers and set priorities for the BACstac future development based on their feedback. If you need any features the BACstac currently does not have; we can always do custom development for you.
Above all, we have a very mature stack that comes with detailed
documentation and great technical support. The price and licensing
model make choosing the BACstac a no-brainer.
Can the customer who
uses BACstac pass a BTL test?
Lyons: Sure. The
majority of our BACstac customers submitted their devices for BTL
testing and passed it.
Do you provide
Lyons: Yes, we do. The
first year is included with the BACstac purchase, and we answer any
questions within a day.
Where can I learn
more about Cimetrics BACstac?
Lyons: Just go to
