BAS and IOT
It is fairly probable that the movement to IOT is also going to change how we look at BAS, controls and integration.

is a fair amount of press about the concept of the “Internet of Things”
– or as it is commonly abbreviated, IOT. The concept of IOT is
simply defined as a network of physical devices. Analysts are
tripping over each other to estimate how pervasive this trend will
be. One predicts 20 billion devices to be connected by 2020 while
another counters that it will be 30 billion. Certainly this seems
like a phenomenon! Still, for those of us involved in building
automation systems (BAS), this seems like a rehash of the same trend
played out over and over again. Remember when it was called M2M
(machine to machine), and back before that when we just called it
controls? After all, is IOT really any different than what we
have been doing with networked, and in many cases, Internet connected
controls for the last several decades?
The answer to this question is complicated. In many ways, building and industrial control systems have largely pre-dated IOT. What is a BAS other than a network of sensors, actuators and control logic? The evolution of BAS has included moving from proprietary to open protocols, and from the use of exclusively dedicated networks to the ability to co-exist on an enterprise network. In many ways, the many millions of connected nodes on BAS networks are already part of the IOT trend.
At the same time, it is fairly probable that the movement to IOT is also going to change how we look at BAS, controls and integration. Here are some likely changes to expect:
Of course, all of
this raises an interesting question: “Will we have a BAS in the future
or is it just part of the IOT?” My opinion is that we will
continue to need a way to safely, efficiently and reliably control
building systems. The need to have qualified designers, suppliers,
contractors, and operators who understand electrical and mechanical
systems as well as controls and IT doesn’t go away. Perhaps what
we call a building control system in the future changes, but the basics
of good control remain the same.
