Smart, Internet-connected devices don’t always get the design attention they need. As a result, they may be difficult to use and lack security, and it will be hard to get different manufacturers’ devices to work together. When industry uses these devices, the problems turn into unnecessary costs and lower productivity. Leading thinkers are looking at ways to set design standards for the IIoT (Industrial Internet of Things). The aim is better and more interoperable products. 

A model-based approach

In an EE Times article, “The Problem with IIoT Design,” Rich Quinnell argues that “IoT designs are all too often piecemeal and rushed to market.” He supports an approach based on “a model-based system of systems.” A single device is just one part of the system, and the overall system is often too complex to grasp directly in full.

Model-based systems engineering provides a method of abstraction which rigorously defines how the pieces fit together. Designers can consider the model separately from the implementation. Each device will comply with the abstract design, so other devices can interact with it in a standardized way. The Industrial Internet Consortium (IIT) is working toward an interoperable IIoT architecture.

Bringing industrial groups together

Three industrial groups, OPC Foundation, OMAC, and PLCopen, have begun working together to reconcile the standards they’ve developed and allow greater interoperability. They plan to fit their efforts together with the IIC’s planned architecture. The OPC UA (unified architecture) is a protocol designed for cross-platform communication based on a service-oriented architecture. It includes both binary and web service protocol definitions. APIs are available in several programming languages.

Standardization promotes innovation

In “The Road to IIoT: What Can We Learn from Other Industries?” John Fryer calls for a standards-based approach. He argues that proprietary standards drive up costs and limit businesses to a single vendor. Using a standards-based infrastructure encourages innovation and makes upgrades easier.

Businesses often equate connectivity with risk, and certainly opening more connections opens more avenues of attack. The IIoT is all about connectivity, though. It’s necessary to work with it and make connections both easy and secure. Fryer advocates “distributed intelligence,” combining all available information gathered from the devices to optimize production and detect potential and actual failures.

Loss of data can be expensive. Fryer stresses fault tolerance, so that a failure at any point doesn’t cascade into a serious break in gathering information. A distributed architecture, rather than dependence on a single server, increases fault tolerance.

Security standards

Security has been an ongoing and embarrassing problem for the IoT. The IIT has published an Industrial Internet Security Framework report. It observes that the design of many industrial devices dates from the days when connectivity was very limited. These designs, brought over into large computer networks, carry risks that the designers never anticipated. Because the devices carry out physical tasks, a data breach could have serious physical consequences. A misbehaving device could trigger a serious industrial accident.

The report states that IIoT security needs to consider both information technology (IT) and operational technology (OT). Safety, in the physical sense, isn’t a major concern in IT, but it’s vital in OT. The framework described doesn’t call for specific technologies but defines a set of layers for building security. The emphasis is on endpoint protection, including physical security, identity, integrity, access control, data protection, and secure configuration and management.

Final thoughts

The development of standards is often a difficult process, as stakeholders each defend their own preferred approaches. It falls upon the product management function to facilitate the dynamic connection between information needed by system engineers using MBSE, evolving standards, and security risk coverage. These three areas can pull a PM in multiple directions and requires careful management. Over time, though, we can expect a consensus to develop, simply because it’s inefficient for each manufacturer’s products to work differently and not talk to the others. With growing adoption of standards, we should see more interoperability, lower costs, better security, and greater productivity.

As a provider of a modern, connected Product Management platform , we at Jama are actively developing technologies and best practices to meet this challenge. Successfully keeping engineering teams on track and tuned into the latest information related to IIoT standards will drive efficiency and cut down risk of defects dramatically.

By 2020 the FAA anticipates the skies will open for about 7,500 private drones of about the size of model planes.   What (IM)Possible things might they be doing up there?

  • Chasing Storms. A team of public-private entities (NASA, NOAA, and Northrup Grumman) entered into an experiment dubbed “Global Hawk”. Global Hawk drones have a wingspan of 116 feet. They can fly for 30 hours at altitudes over 55,000 feet and up to 11,000 miles away. They provide surveillance and data collection inside storms where piloted planes cannot go. The idea, of course, is that knowing and understanding more about how storms develop will help save lives on the ground as well as reduce the financial cost storm damage creates.
  • Safety Inspections. Drones are masters at finding structural flaws, not only because they can quickly and efficiently take high-resolution but also because they can get up close in treacherous spaces, such as the underside of an offshore drilling rig or the top of a cell tower. The technology could one day be deployed to spot-check roads, bridges, pipelines, dams, and other public works. That could allow for better use of limited tax dollars, and save hundreds of lives in the process.
  • 3-D mapping. Military and government satellites currently provide 3-D mapping but drones can change that by putting 3-D imaging into private hands. Today’s drones are no longer run by a remote; they use GPS to navigate and they have a good safety record. The 3-D maps uses range from hurricane relief, to farmers managing far away crop-bearing fields, to mining companies managing open-pit mines, to security companies keeping tabs on large crowds.
  • Search and Rescue. The Royal Canadian Mounted Police (RCMP) rescued a driver in a remote area who had rolled his vehicle over and then wandered away. The RCMP’s used a drone to locate the driver with heat-sensing equipment and saved his life. Search and Rescue missions are expensive and dangerous for rescuers. The use of drones may soon become standard especially in large inaccessible areas, at night
  • First Responders. Better yet, aerial footage provided by drones keeps early responders out of harm’s way. For example, in a SWAT scenario a camera-equipped craft can give officers a close-up look at a compound where hostages are being held—while they remain at a safe distance from the threat. Or a fireman with a thermal-­imaging drone and video-streaming capability over a four-alarm blaze can determine, in real time, where to direct his colleagues and where to help them avoid trouble.
  • Wildlife preserves.  US Department of Interior, Bureau of Land Management, and US Geological Service use drones to oversee animal populations and to map roads/wetlands in their land management duties. These agencies use government surplus drones like thermal imaging cameras to check on birds when nesting at night. And drones (in a project sponsored by Google and World Wildlife Federation) help authorities crack down on illegal poaching of ivory and rhino horns. The drones keep rangers out of harm’s way while bringing stability to areas where criminal gangs of poachers threaten national security.
  • Progressive Farming. Precise application of fertilizers and pesticides, possible with drones, is better for the environment and saves the farmer money. Drones identify the fields that need the chemicals (or water) and can deliver their payload with pinpoint accuracy. Drones with infrared cameras can monitor plant health by reporting back on the efficiency of a plant’s photosynthesis.
  • Humanitarian Aid. According to the World Health Organization, an estimated 2.1 billion people on the planet don’t have access to essential medicines due to remote access.  California drone maker Zipline has launched “Zip” drones, which cover a roughly 50-mile radius and can send a text message to order blood for a patient in need and it shows up via parachute within 40 minutes.
  • Internet Access. Well over half the planet’s population currently has no internet access. That means no Facebook or Twitter, of course, but also no email, no world news, and no access to online commerce. More than one notable Silicon Valley fixture is looking to change the game lightweight drones that will cruise high above normal airspace delivering connectivity to people within as much as a 60-mile radius. As some early setbacks indicate, this is not an easy problem to solve.  But it’s one that could pay off immensely if they can be among the first to help connect a new generation of internet users around the world. I give that a “like”.
