I’ve been thinking deeply about the industrial internet and the greater industrial ecosystem. A friend passed along an article from ZD Net written by Simon Bisson, “There’s A Huge Void At the Heart of the Internet of Things.”
The deck of the article reads, “Closed systems do not an internet make. It’s time to change that before it’s too late.”
He knew I was working on some white papers for MIMOSA and the OpenO&M Initiative on interoperability of standards in the larger industrial ecosystem. In the case of what I’m writing, there exists a gap in areas covered by Enterprise Business Systems, Big Data and Analytics, Automation and Control Systems, and Life-Cycle Engineering Systems. The gap can be filled with Supplier Neutral Open Standards and Specifications.
Bisson writes, “Sensors are everywhere, but they’re solitary devices, unable to be part of a holistic web of devices that exposes the world around us, giving us the measurements we need to understand and control our environments.”
He notes a few feeble movements toward developing “communication and API standards for these devices, through standards like AllJoyn and Open Connectivity Foundation, the backbone is still missing: a service that will allow us to work with all the devices in our homes.”
Industrial Internet broadly speaking
Typical of a consumer-facing publication, he’s thinking home. I’m thinking industrial in a broad scope.
He continues, “Building that code isn’t hard, either. One of the more interesting IoT development platforms is Node-RED. It’s a semi-visual programming environment that allows you to drag and drop code modules, linking them to a range of inputs and outputs, combining multiple APIs into a node.js-based application that can run on a PC, or in the cloud, or even on devices like the Raspberry Pi.”
Bisson concludes, “The road to an interoperable Internet of Things isn’t hard to find. We just need to remember that our things are now software, and apply the lessons we’ve learnt about building secure and interoperable systems to those software things. And once we’ve got that secure, interoperable set of things, we can start to build the promised world of ubiquitous computing and ambient intelligence.”
I’d take his consumer ideas and apply them to industrial systems. The work I’m doing is to explain an industrial interoperable system-of-systems. I’m about ready to publish the first white paper which is an executive summary. I’m about half done with the longer piece that dives into much greater detail. But he is right. Much has already been invented, developed, and implemented at a certain level. We need to fill the gap now.

[This article is updated as of 10/30/19. I received information that noted Google’s Tango has been shelved, but that there is still work being done on the platform. Thank you to Luke Pensworth of Daily Wireless.]
This news is a little outside my usual commentary, but it does reflect a trend. Augmented reality developments have grown steadily for many years. I first wrote about it before it had a name in the late 1990s regarding maintenance applications. Potential applications now are growing faster than the imagination right.
This “first-of-its-kind mobile augmented reality solution” creates a life-size 3D, virtual vehicle to enhance the car buying experience.
Fiat Chrysler Automobiles (FCA) unveiled a prototype of an immersive car sales application at Mobile World Congress designed and built by Accenture Digital using Google’s Project Tango developer kit. The prototype demonstrates how augmented reality can revolutionize the shopping experience for consumers by allowing them to view and interact with a full-scale virtual version of the object – or car – they are considering buying.
The prototype allows car buyers to hold a device and, using the integrated sensor technology and motion tracking, area learning, and depth perception from Project Tango, view, walk around, look inside and configure a life-size virtual car. On the Accenture demo, doors can be opened to reveal a realistic and detailed interior, where changes to upholstery colors or dashboard styles can be made with a tap on the device screen.
Project Tango technology gives mobile devices the ability to navigate the physical world similar to how we do as humans. Project Tango brings a new kind of spatial perception to Android devices by adding advanced computer vision, image processing, and special vision sensors. A Project Tango device maps the 360-degree environment around it, meaning that as it is moved it navigates and views the changing environment in the same way as a person would. As the car is viewed through the device, the virtual car moves in relation to how the user moves.
The first commercial Project Tango device is expected to be available in summer 2016 and this application will be previewed to attendees of this year’s Mobile World Congress. Accenture Interactive, part of Accenture Digital, has worked with FCA to create an application for this new technology that will transform the process of buying and configuring a new car.
Untethered Augmented Reality Experience
Users of the FCA car configuration solution will be able to walk freely around a full-scale vehicle in almost any environment because Project Tango enables an untethered, handheld experience that does not rely on external tracking technology such as markers, beacons or GPS.
“Project Tango is a new, unique technology that is set to become standard functionality in the next generation of mobile devices,” said Matteo Aliberti, Digital Innovation lead for Accenture Interactive EALA. “Accenture has been experimenting with Project Tango and potential business uses for as long as it has been in development, creating a range of potential applications, including this one for the automotive industry.”
Accenture’s design-led development of this solution means that the process of making decisions about cars will be completely transformed with the new generation of mobile devices. FCA is the first automotive brand to use this type of digital car configuration tool. Today’s car configurators are essentially flat, so with this tool FCA customers could have a more interesting and immersive experience.
This work is the latest collaboration between FCA and Accenture that aims to deliver a new and unique digital experience for FCA customers.
“Augmented reality is set to transform the way car-buyers choose and configure vehicles through the provision of immersive technology because it provides an enjoyable, delightful experience for customers,” said Luca Mentuccia, senior managing director and head of Accenture’s Automotive practice. “We believe dealers and car buyers will be quick to embrace this enhanced way of buying a car as the new devices become readily available, taking advantage of the 360-degree mapping environment to create this unique experience.”

Everyone is in a rush to get an opinion or observation published about the Internet of Things. Evidently it gets lots of page views. Recently other analysts have been publishing thought pieces on IoT in Industry. It appears they have reached the same conclusion that I first broached a couple of years ago. The IoT is not a “thing.” To make any sense of it and use it for any strategy, it must be thought of as an ecosystem encompassing a variety of technologies.
Here is an article that appeared in the Sloan MIT Management Review. Since I am a subscriber, I don’t know if you can see the article at this link.
The writer is Sam Ransbotham is an associate professor of information systems at the Carroll School of Management at Boston College and the MIT Sloan Management Review Guest Editor for the Data and Analytics Big Idea Initiative. He suggests, “The Internet of Things will bring huge changes to the way markets and businesses work — and it could get messy.”
Here is a bromide that I’ve read a thousand times, “Most businesses aren’t ready for the changes to the marketplace that the Internet of Things will bring. But the time to prepare for them is now.”
Actually most business adapt. Some are visionary and will develop new products, processes, and services–and make a lot of money. Others will adapt and survive. Still others will wonder what happened and die. That is the way of business for at least 5,000 years.
Use Case for Internet of Things
“Yes, the potential insights from IoT are enticing. For example, it’s fun to think about the potential personal and even societal benefits from self-driving cars, such as fewer accidents, no problems with parking, more productivity while traveling, car sharing, greater infrastructure efficiency, etc. But perhaps a more profound implication is the data that they can collect. These cars will also be widely distributed “things,” gathering performance data that can help manufacturers diagnose problems, operational data that can help mechanics prevent failures, driver data that can help insurers understand risk, road data that can help cities improve infrastructure, etc. These kinds of insights, we’re ready for.”
But there are a lot more changes coming with the IoT transformation than many people may recognize.
Ransbothem looks into information technology as a model for what will happen in IoT. “About a decade ago, advances in information technology converged to fuel a boom in corporate use of analytics. First, widespread implementation of information systems captured unprecedented amount of data in ways that could be used in isolation or combined. Second, tools and technologies allowed the inexpensive storage and processing. Third, savvy analytical innovators creatively combined these to show everyone else what could be done.”
We have seen all this play out in industrial systems. There remains more to be done, here, though.
He proceeds to look at Internet of Things. “First, the cost and physical size of sensor technology have dropped such that they can be incorporated into most items. Second, widespread communications infrastructure is in place to allow these distributed components to coordinate. Third, once again, savvy innovators are showing the rest of us the possibilities from the data they collect.”
Manufacturing and production are not only poised to exploit these technologies and strategies, they have already been implementing to one degree or another. But his point is valid. IoT needs the ecosystem of sensing devices, networking, communication technology, databases, analytics, and visualization.
Ransbothem identifies four areas of change. Of these, I direct your attention to the last–process changes. I think everything feeds into process changes–not just the processes to make things, but also the information technology, supply chain, and human processes that must not only adapt but thrive with the new information awareness.
- Market Power: IoT should provide a greater amount and a greater value of data, but are companies ready to align their interests in obtaining value from this data with the multiple other companies and end users who create, own, and service the products that originate the data? In the driverless car example, it is easy to see how multiple stakeholders could make use of the data from cars; the same is true for other devices. But it may not be clear who owns what data and how it can be used.
- Complexity: Few organizations are prepared to be hardware and software development companies. But that’s what the Internet of Things will enable. As products are built with embedded sensors, the component mix increases in complexity. As a result, manufacturing systems and supply chains will become more elaborate. Software embedded in products will need to be updateable when the inevitable shortcomings are found.
- Security: If we believe data is valuable, then we need to be ready for people to want to take it from us — why would data be any different than any other precious item? The IoT context intensifies the need for security requirements; for example, sensors or software that allow physical control of the product make attacks easier.
- Process Changes: Many business processes continue to be “pull” oriented. Information is gathered, then analyzed, then decisions are made. This works when change is slow. But with the IoT transition, data will stream in constantly, defying routine reporting and normal working hours. Flooding data from IoT devices will give opportunities for quick reaction, but only if organizations can develop the capacity needed to take advantage of it. Few mainstream large companies are ready for this, much less small- to medium-sized companies that lack the resources of their larger corporate brethren.
The Internet of Things is bringing and will continue to bring advances in how we do business. How well will executives, managers, and engineers execute on this vision? That is key.

Following on to last week’s quick post of PTC’s Internet of Things acquisition of Kepware, I’ve gone a little deeper into the build up to and the strategy of the acquisition.
First off, the Internet of Things is a strategy. It isn’t a “thing.” PTC management seems to “get it.” As you’ll read further down, PTC is not pursuing a simple bolt-on strategy such as what several companies have come to me to help justify. This appears to be a serious attempt to assemble a complete ecosystem / platform going beyond a simple IoT play to offer a business solution to customers.
Warning note. PTC is acquiring software companies and attempting to blend their technologies into a coherent whole. We’ve witnessed many of these seemingly simple processes go south quickly. But PTC has done this before in its core market, then again in the services market. I have confidence the company will show the way in a complete solution.
PTC is paying a large premium for Kepware–Up to $120 million for a company with about $20 million in annual sales. It obviously thinks there is a tremendous upside to its IoT business.
From the press release: PTC announced it has signed a definitive agreement to acquire Kepware, a software development company that provides communications connectivity to industrial automation environments, for approximately $100 million, plus up to an additional $18 million based on achievement of certain strategic initiatives and financial results. The acquisition will enhance PTC’s portfolio of Internet of Things (IoT) technology, and accelerate the company’s entry into the factory setting and Industrial IoT (IIoT).
Founded in 1995 and located in Portland, Maine, Kepware serves customers in more than 120 countries in such industries as manufacturing, oil and gas, building automation, and power and utilities. The company’s flagship product, KEPServerEX, connects disparate devices and control systems, providing users with a single source of industrial data.
Kepware’s KEPServerEX will become a strategic component of the PTC ThingWorx IoT technology platform. Once the companies’ products are integrated, machine data will be able to be aggregated into the PTC ThingWorx platform, integrated with a wide array of internal and external information, and then automatically analyzed using ThingWorx machine learning capabilities. The integration will allow organizations to gain enterprise-wide insight and to proactively optimize mission-critical processes – enabling them to improve operational performance, quality, and time to market.
In its June 2015 research report, entitled The Internet of Things: Mapping the Value Beyond the Hype, the McKinsey Global Institute identified the factory as one of the largest sources of potential value to be realized from the adoption of the Internet of Things. PTC has established a dedicated business segment and has formed a strategic alliance with GE to pursue this brilliant factory opportunity. The acquisition of Kepware is intended to complement the alliance with GE.
Kepware and PTC share many common customers that will be able to realize value from the acquisition. Industrial environments already leveraging Kepware technology will be able to benefit from the added breadth of capabilities available in the PTC ThingWorx IoT technology platform. The acquisition of Kepware will also provide a fast-to-value connectivity option for PTC customers to gain visibility into data from a vast range of industrial controls and production equipment, enabling them to kick-start their smart, connected factory initiatives.
“PTC is committed to helping manufacturers, infrastructure operators, and others realize the enormous value inherent in the Internet of Things,” said Jim Heppelmann, president and CEO, PTC. “With this acquisition, we will gain entry into heterogeneous factory and operating environments with robust technology, an impressive list of customers, and a high-quality, profitable company with incredibly talented employees.”
“Kepware and PTC share a common vision of helping organizations realize the potential of the Industrial Internet of Things,” said, Tony Paine, CEO, Kepware. “We believe this acquisition will benefit our customers, partners, and employees – and ultimately drive software innovation for industrial automation markets. We are excited for the opportunity to become part of PTC.”
Over the past 12 months, privately-held Kepware generated approximately $20 million in revenue. PTC expects to draw on its credit facility to finance this transaction and expects Kepware to be neutral to its FY’16 non-GAAP EPS. The transaction is expected to close in early 2016, subject to customary closing conditions, including regulatory approval. PTC intends to maintain the Kepware partner ecosystem and to continue developing and enhancing the Kepware technology, once acquired.

KEPServerEX Overview
KEPServerEX is a communications platform that provides a single source of industrial automation data to all of applications. The platform design allows users to connect, manage, monitor, and control diverse automation devices and software applications through one intuitive user interface.
KEPServerEX leverages OPC (the automation industry’s standard for interoperability) and IT-centric communication protocols (such as SNMP, ODBC, and web services) to provide users with a single source for industrial data. Designed around the four product pillars of Proven Interoperability, Centralized Communications, On-Demand Scalability, and Industrial Strength, KEPServerEX is developed and tested to meet our customers’ performance, reliability, and ease-of-use requirements.
Product Features
KEPServerEX provides critical technical features that are centralized around accessibility, aggregation, optimization, connectivity, security, and diagnostics.
Accessibility
OPC
OPC is the leading standard for industrial automation connectivity. KEPServerEX supports the OPC Unified Architecture (OPC UA) specification and many of the OPC Classic specifications, including OPC Data Access (OPC DA), OPC Alarms and Events (OPC AE), and OPC Historical Data Access (OPC HDA).
Automation Interfaces
KEPServerEX has preferred access to leading automation software, including iFIX by GE Intelligent Platforms (NIO) and InTouch by Wonderware (SuiteLink/FastDDE). KEPServerEX also supports preferred access to Oracle MES and MOC solutions through their proprietary API.
IT Interfaces
KEPServerEX supports multiple interfaces for integration with IT applications, including ODBC for logging information to a database and SNMP for providing information to a Network Management System (NMS). With the advent of IoT and Big Data applications, KEPServerEX now includes the ability to communicate with Splunk software and cloud services via the Industrial Data Forwarder for Splunk.
Cloud Interfaces
With the IoT Gateway, KEPServerEX can seamlessly stream real-time industrial control data directly into Big Data and analytic software for Business Intelligence and Operational Excellence. Its customizable data format supports most MQTT and REST applications—enabling users to choose the vendors and communication methodologies right for their system.
Exporters
Some applications require information to be made available from a file or database. This information is typically exported at a predefined rate and includes both current and historical data. KEPServerEX has the ability to export historical Electronic Flow Measurement (EFM) data (via the EFM Exporter plug-in) or historical trend data (via supported drivers) to files and/or databases.
Aggregation
Centralized Platform
KEPServerEX is a communications platform that can support connections to thousands of data sources and provide information to hundreds of applications. The platform design simplifies the configuration of the connected applications by providing a single point of entry to all information. KEPServerEX also enables troubleshooting and issue diagnosis, provides control to the access of information based on user roles, and the ability to restrict the frequency of communications over bandwidth-limited telemetry-based environments.
Unified Configuration
KEPServerEX provides a unified configuration for managing connectivity to any data source. Anything can be added, configured, or deleted while the server is on-line and operational. Users can configure projects manually using a step-by-step wizard or programmatically through the export and import of XML and CSV files.
Data Storage and Retention
KEPServerEX is capable of archiving the real-time data it collects to local storage. By leveraging the Local Historian plug-in, applications can access this historical data (via OPC HDA) for future analysis. KEPServerEX can also store information in any ODBC-compliant database using the DataLogger plug-in, which has a store-and-forward capability for when a database is unreachable or unable to process the information fast enough.
Optimization
Data Conditioning and Reduction
In addition to providing raw values to connected applications, KEPServerEX can perform linear or square root scaling, perform basic arithmetic expressions, or apply deadband calculations on raw data and provide its aggregate. This provides minimal bandwidth and resource utilization by providing only the most critical updates.
Redundancy
KEPServerEX is used in critical applications where highly-reliable systems are required for maximum uptime. It includes the ability to define redundant network paths, primary and secondary data sources, and applicable failover criteria.
Load Balancing
In large networks that have many devices and applications requiring information, flexible control is necessary to allow for customized load-balancing of data collection and information flow. KEPServerEX provides tools to schedule the frequency of communications and throttle the demand across the network.
Communications
KEPServerEX optimizes communications with devices by aggregating identical requests from different applications whenever possible. Multiple demands on data can be batched together into the fewest requests possible. These optimizations are unique to each protocol, and are designed to reduce network overhead and device processing.
Machine-to-Machine Linking
In a typical industrial automation network, devices and controllers must communicate with one another even if they are not from the same manufacturer or do not support the same protocol. KEPServerEX provides the ability to establish links between data values in different data sources, allowing Machine-to- Machine (M2M) communications as close to the device as possible.
Connectivity
Driver-Based Access
KEPServerEX offers the broadest range of drivers available, supporting devices across various verticals within the Industrial Automation Industry. While most drivers act as masters that initiate requests, there are many drivers that can emulate a device where communications are driven by a controller. KEPServerEX drivers also support a variety of wired and wireless network mediums for Ethernet, serial, and proprietary networks. Although most drivers connect directly with hardware devices, some are designed to connect with other applications—such as databases, custom software applications, or other OPC servers.
Telemetry Environments
Industrial automation equipment can be deployed in a dry and heated factory, but it can also be installed inside a vehicle, on a remote pipeline, or in a well or pump station. In these remote environments, there are often a variety of telemetry solutions in use like cellular, radio, or satellite modems. KEPServerEX supports these telemetry configurations and provides additional ways to optimize communications through virtual networks, timing parameters, device demotion, and by scheduling communications across devices.
Rapid Deployment
As automation networks have grown from ten controllers to thousands of controllers, tools that aid and accelerate deployment are critical to a solution’s success. KEPServerEX provides many tools that speed the deployment of new devices, including Automatic Tag Generation (ATG) and Device Discovery (when supported by the device and communication protocols). Users can also export, manipulate, and import an XML project file to programmatically define the configuration.
Simulation
As systems are configured, components must be implemented and tested before the entire system becomes available. KEPServerEX allows any data source to be placed into simulation mode prior to deployment. In addition, the Memory Based driver can be configured to create a range of static and dynamic data points. The Advanced Simulator driver can leverage a database and its contents to drive application-specific simulation data into connected applications.
Security
Configuration
Access to the KEPServerEX configuration can be restricted through the User Manager. This tool allows the administrator to define user groups and users with restricted access to certain project configuration tasks, and also provides the ability to disconnect client applications.
Runtime
There are various tools available within KEPServerEX to control user access to the server, data source, or data values. The Security Policies plug-in limits access based on OPC UA user credentials while supporting default handling for anonymous users (both OPC UA and other client interfaces). The ability to dynamically address information can be disabled, limiting user access to tags defined within the project. KEPServerEX supports a number of secure client standards including SNMP (v3 security), OPC UA, and OPC DA (DCOM security) to further restrict access to the server, as well as a number of secure device protocols to meet the requirements of DNP3, SNMP, and OPC UA data sources. Secure data tunnels can be configured by leveraging multiple KEPServerEX instances at remote endpoints to pass data through firewalls and meet authentication and encryption requirements across the Internet.
Diagnostics
OPC Diagnostics
OPC Diagnostics provide a real-time and historical view of OPC events between any OPC client and the server, including method calls made by the client or callbacks made by the server. The ability to view actual communications and responses is invaluable when troubleshooting client accessibility. The diagnostics tools within KEPServerEX greatly speed deployment and reduce downtime.
Communications Diagnostics
Communication Diagnostics provide real-time capturing of the protocol frames transferred between the server and any device, as well as indications on the driver’s performance. All read and write operations can be viewed or tracked directly in an OPC client application using built-in diagnostics tags. This is useful when modifying key communication parameter settings (such as baud rate, parity, or Device IDs), because corrections are immediately visible.
Third-Party Diagnostics Integration
Diagnostics information can be viewed within KEPServerEX and by third-party applications. Diagnostics information is provided through system-defined tags and accessible to the same clients connecting to the data sources. KEPServerEX logs event information, which is accessible within the configuration tool or to any application that supports the OPC Alarms and Events specification.
