INTECH MARCH/APRIL 2017 25 SYSTEM INTEGRATION rhetorically asked the audience if IoT had peaked and also wondered if "cyber" would be the next area for innovation. This article explores the nexus of "domestic" IoT and how product evolution will drive its development toward that of IIoT. U.S. government to promote IIoT evolution? On 1 September 2016, the National Telecommuni- cations and Information Administration within the U.S. Department of Commerce (DOC) conducted an IoT workshop. Discussions included how IoT and IIoT were set to converge around common threads. An important area of convergence will oc- cur around onboard components and subsystems, with software as a runner-up because of cost and the innate drive to be first to market. However, as the recent Samsung Note 7 battery failure and sub- sequent recall has shown, releasing a product with flaws that are later discovered in the field by your customers is a bad idea. Despite this, the hype sur- rounding IoT is truly at its peak relative to other emerging technologies. President Trump has targeted infrastructure as a key agenda item in his administration. This proposed infrastructure buildout combined with growth in U.S. industrial capacity would benefit from incorporation of IIoT sensors and systems. At the Consumer Electronics Show (CES) in January 2017 in Las Vegas, many companies demonstrated attempts to deploy IIoT in industrial facilities—of - ten with woefully inadequate performance and cybersecurity. The rush to develop and deploy will no doubt increase consumer IoT being used for IIoT (again, as on display at CES 2017), accelerat - ing the IoT and IIoT convergence. At the DOC IoT workshop, participants spent a significant amount of time discussing the im- portant role government can play in setting IoT standards. IoT experts at the workshop made it clear that with assistance from the federal govern- ment—specifically the U.S. Department of Energy (DOE) and DOC and their national laboratories— guidelines for cybersecure and robust IoT could be developed. With help from the government and or- ganizations such as ISA, industry will have a clearer path to develop industry-centric IIoT rather than rushing to field consumer IoT devices. The ques- tion is that, even with this framework, will simple cost and a discount of risk dominate, so that IIoT essentially becomes IoT wrapped in a harder shell? We propose that this is what will occur. However, we must take heed when it comes to cy- bersecurity and realize that with commercial IoT, an industrial target could be attacked in a manner simi - lar to an attack on a commercial target—but with very different consequences. The solution? Although we should accept that IoT and IIoT will converge, there must be clear distinctions in cyberarchitecture and associated protections. This goes for implemen - tation as well as regulations and guidelines proposed by governments and industry standards developed by organizations like ISA. Industrial Internet of Things Could seemingly trivial items, such as Amazon Echo/Alexa, be worthy of consideration for industri- al automation and applications? Many stalwarts of the status quo voice concerns about safety standards and dangers of this technology in the industrial set- ting. Although these are valid concerns, a more im- portant concern is that commercial IoT standards or best practices do not always apply to IIoT concerns. IIoT is a specialized IoT implemented in rug- gedized packages suitable for industrial applica- tion environments. In fact, legacy industrial control devices, such as programmable logic controllers, will be compatible—for the time being—with IIoT running alongside. IIoT benefits from data flowing through standards-based and common networks. From a networking standpoint, the IIoT systems will break the ongoing practice of using proprietary networks and bring into place a common standards- based networking technology. The convergence of IT and operational technology (OT) operation knowledge for industrial automation environments FAST FORWARD l IIoT may essentially become IoT with components wrapped in a harder shell. l IIoT benefits from data flowing through standards-based and common networks. From a networking standpoint, the IIoT systems will break the practice of using proprietary networks and put into place a common standards-based networking technology. l The convergence of the IT and OT knowledge for industrial automation environments is well underway. Soon IIoT will approach the network edge for almost every industrial application.
