The world is going crazy for connected devices and the Internet of Things (IoT): Nearly 25 million smart speakers were sold last year, with about 11 million moved in the holiday season alone.1 So why the fuss around Industrial IoT? Instead of a dumb device getting smarter (as with Bluetooth-connected speakers), you now have the potential to make a smart device — an industrial temperature controller — truly brilliant. But, how do you also protect from cyber-threats?
An earlier Process Heating article2 outlined how it is possible to wrap modern technology solutions around existing assets. Doing so allows users to leverage cloud technology to improve the maintenance of burner tuning through predictive methods — and ultimately save energy. Such upgrades were achieved by using a tablet or smartphone to take field readings, and that information is analyzed over time to predict when burner adjustments are necessary to optimize combustion performance. Unfortunately, these solutions do not have a physical connection to the temperature control system that manages the industrial burner operation.
