Recent History on How We Got to the Edge
Since every object is a real life device, programming methodologies will completely change. Every equipment manufacturer will store and build essential algorithms into their devices which will give them an edge.

While reading our
August lead article the Era of
Hybrid Edge Controllers I gained a better
understanding of the power of the edge. This is a very
evolutionary article with a lot of head shakes that question how
we now do stuff, and is embedded with insight to the changes
It got me thinking about a conversation Alper and I had several years ago that inspired me to write this endless article.
“The Past and Future of Control Languages”
A call to the industry to speed their evolution to open protocol for
Many industry experts contributed to this never ending article. Both Alper and Toby talked to the movement to the edge in 2008 and 2009.
From this column by Toby Considine, Clouds and Rain comes this wisdom:
For Brandl, nearly everything is a cloud; only the core control processes are on the ground. I think this is right; for buildings, only the core processes, those elements on the traditional low voltage protocols such as BACnet and LON, are on the ground.
Therefore the core control
language must be on the ground and closely coupled with DDC control. The
optimization of this language will come from web services in the cloud.
Optimization will no longer be contained in the DDC control language. Optimization and the necessary Interaction will come from complete web services solutions and smart grid interaction from the cloud.
The complex dynamic optimizing control coding of the past will be part of actual major equipment control and part web services.
Optimization and the necessary Interaction cannot exist with our existing proprietary control languages but only exist in a mash up of dynamic web services that will provide the results we are looking for.
Alper's August 2011 article Controls Spring What if the controls contractor had a standard open programming language? When they are building DDC code they are actually generating the O&M manual and graphics by definition and the code is vendor independent. When the new controls contractor walks into the building, they see all the data digitally about the building. They can actually query the system. - Alper Uzmezler, BAS Services & Graphics, LLC keeps defining the future of control Languages and how they will shared between the edge and cloud.
In this 2009
article Future of Building Automation from Alper Uzmezler comes these thoughts:
Pure object oriented programming for Building Controls
Since every object is a real life device, programming methodologies will completely change. Every equipment manufacturer will store and build essential algorithms into their devices which will give them an edge over their competitors. For example, a VFD manufacturer will essentially create algorithms that will optimize their PID loops inside their equipment. Damper actuators will have more optimized PID loops based on their communication skills to the cloud.
I think this new Era of Hybrid Edge Controllers article is a evolution of the history of Alper predicted. Wow, 2009 he told us this was going to happen.
Then all he had to do was make it happen.....smile.
I find this an interesting twist of recent history that is evolving
here on our web site.
I am still smiling inside that I am reporting the history of that young energy guy at connectivity week.
Flash back to 2009
was originally unsure he would be able to attend Connectivity Week but
life on hold to come late but to add to the YoungEnergy group and is
not in the picture but as you can see by his article of last month and
his reaction to the stuff he saw at CW he is positioned to change the
industry. Go Alper go!
Future of Building Automation
Alper Uzmezler, BAS Services & Graphics, LLC.
It is clear that now for the history of things we need to not look too far back and those that will change the world are already in our industry.
I will say it again "He is positioned to change the industry. Go Alper go!"
In March of this year he wrote
Energy Analytics Controllers Edge devices now have the intelligence and data storage they need for local analytics and machine decision-making. They’ll soon be the thing that the rest of the BAS universe revolves around. - Alper Üzmezler, BASSG LLC.
people say that we are living in the post-PC era they mean that the
personal computer is being eclipsed as the center of the IT universe by
Operations technology is experiencing a similar reordering. In this new
era of the Internet of Things (IoT), compute resources equivalent to a
PC or smartphone are being integrated into all sorts of equipment and
devices. For commercial buildings, a new category of IoT device is
Energy Analytics Controller (EAC).
Smart building applications development should revolve around the
enormous possibilities of these edge devices.
Fun stuff for sure
