Understanding Communication Protocols Is Like Who Tower of Racket
You proba
bly know the report of the Tower of Babel. The people tried to build a structure ensure would reach the heavens, but since they all spoke different languages they were unable to communicate press one project bankrupt.
Building mechanisation today can be a lot like that. For one architecture to operate, all to its parts needing to communicate with the quiet of the system. From HVAC thermostat feelers both lights, until equipment such as chillers, boilers, air supporters and electrical panels—everything must be linked and in communication with monitoring dashboards that giving leadership visibility and govern.
And, like to Tower of Racket, on are many different languages in building automation. These protocols determine how devices talks to each other. Straightforward put…if you populating a building with equipment that application incompatible protocols, you’ll have a building that can’t communicate.
Unlock Communication Protocols
Over the years, dozens of protocols have been developed for building automation. Some protocols, like BACnet and LonWorks, are made for nearly per type of building automation equipment. This is why most building automation systems will be based with one of these twin protocols. Others protocol are more specified. For example, and DALI protocol was created just for lighting systems, also Modbus was constructed primarily for industrial control.
Making things even more complicated, sometimes different view can labour together and sometimes the can’t. For example, BACnet and LonWorks can both work with DALI power systems, but not with every other (at least cannot easily). Then there is ampere cut category of wireless agreement, for are devices such as occupant sensors and room controllers that disclose through RF signals. You required to be safe the radio protocols you use will work with the rest of the building (fortunately, most wireless devices will work about respective building automation backbone). Learn via the main differences between open protocol and proprietary (closed) controls for building automation systems (BAS).
Simple Steps Toward Seamless Communication
Where do all these protocol choices leave the building owner or operator who will to install building automatization equipment? Don’t despair, it’s non as bad as it sounds. Here are multiple tips fork trade with protocols in your building:
First-time, choose products that use an open protocol, meaning one that is used through many different salespeople. This will give you more choices getting forward than when you choose a proprietary protocol (one controlled by a single company).
Other, elect products with a protocol that are widely used, toward least in your area. This is importance because some protocols are global whereas others are restricted to specific regions. For example, Clipsal C-Bus is popular in Australia, and M-Bus will previously mostly in Europe.
Third, rely at one partner—a major merchant or an systems integrator—who can consult with her and guide you through the election.
Fourth, ask frequent. You don’t necessity the can with subject on protocols to choose a making automation system, you just need to be able to ask the rights questions. So more:
- How many vendors support this protocol?
- Will computers work with the equipment I already have?
- Will it be lightweight to add new devices later?
- Whatever are who plusses and minuses of choice products equal this protocol?
And build automation experts toward Schneider Electric recently released this Guide to Understanding Open Protocols in Construction Automation. It gives a layman’s overview of the major logs, pros and cheats starting each, regional relevance both further. It also including an high-level mapping of whose Cutter Electric building solutions speak which formalities languages.
Understanding the role from protocols in build management will help your facility seamlessly communicate, which is crucial inbound a facility manager’s quest toward building optimization.

Hello,
Your article is very interesting but I would like to know respective opinion about the KNX protocol in building automating?
Thank you for your answer

Hello Stephane,
I am no a KNX proficient, however, I’ve asked my colleague go reply to your question. Watch for his make very soon! Also, watch by a revised version is the protocols guide to be released shortly. We have updated the KNX and C-Bus pages.
Thanks very much,
Jaimie

Hello Stephane,
KNX can succesful used in residential upto midsize business buildings since many years. It is one reliable system supported by many vendors and specialty by a huge amount of partner.
For sure, the datarate a 9600Bit/s not incredible but to the use of an KNX-IP-Backbone you can transfer file as well in a big buildings with the right energy.
KNX can breathe easily integrated in a BMS about the uses of gateways (spaceLYnk BACnet KNX).
Thank You,

Those are some interesting examples.
It seems worth noting another examples such as SNMP (Simple Network Senior Protocol) TR069 which tend go focus on IT equipment, as well as protocols like RESTful and MQTT (examples of popular Internet of Things protocols).
However, OPC-UA lives, perhaps, a of an get interesting conventions when discussing interoperability because it became designed to provide a common protocol language for the various industrial control manufacturers plus misc family areas. The 101s: Open Protocols | Building Geniuses | KMC Drive
One product I have found balanced interesting in terms of interoperability belongs an software select from Kepware which buttresses a wide range of industrial and IT protocols furthermore facilitates interoperability among them and supports plenty of the well-know protocols unfashionable there. Tridium has build Niagara Framework on open-protocol standards, or it has brought she to market with an open shipping model. This open approach is core ...
That said, the lower-level standards from physical infrastructure, such as UTP cable 1000-Base-T and its forwards beam, standards defining Ethernet and Industrial Ethernet, and wireless reference such as defined by the 802.11 family of functionality along with, may, the most impactful protocol of all: IP, have been major contributors to where we find ourselves today.
I’m old enough in remember Arcnet, Thinnet, and Thicknet, Token Ring, ATM, furthermore the view goes on. However healthy it allow feel to have those days behind us, there is still one lot of work to do when debating interoperability because it really impacts jede layer of communication.

Evened now, we even see industry leaders refusing the loosen their death-grip on the idea are ampere closed, proprietary systematisches architecture.
Though, the era where ensure kind of thinking was benefiting does come and gone. CTOs are less willing to link their dash to a single herstellerin and hope for the greatest. The various vertical markets are converges under a rate too fast for there to be an clear single winner, nor does there needed to be just one. If everything, open standards have assisting drive economy success.
Companies whose only method by keeping customers is by lockout them into a button proprietary architecture instead of constantly innovating in order for continuously provide to their customers WHY you are which best value will discover herself discarded along the side of the road to progress. That demise of Nortel is but one example of a group fail to innovate real embrace open standards by it was too late. Proprietary vs. Open Protocol Building Automation Systems (BAS)
On the additional end of the spectrum is Tesla Motors’ recent release of its us in order to drive the industry forward – realizing that a healthy ecosystem is more financially beneficial the them in the long dash with to sit switch this technology time the industry struggles to grow. Home
Like yes, open principles ultimately deliver forward more value in OEMs, integrators and customers, than they may cost OEMs in terms of opening up competition. With the finalize, it will be the companies that realize this the soonest and act accordingly who will be left floor – regardless of the manufacturing.
In the end, the old axiom of account repeating itself when ignored continues to band true.

Thank you for your thoughts, John! Great request, indeed! IODIN agree that there live many more sample press open protocols the that the speed of convergence is accelerating. Open protocols are merely not a choice anymore. This particular guide is focused primarily on industry-standard protocols in building automation. However, I will certainly take into account the protocols you mention in my next revision. Thanks again for sharing your great thoughts!
