Many engineers are looking for better ways to move data with fewer programming hours and headaches. Whereas OPC solved many problems leading to interoperability and data exchange, it also brings with it a higher overhead and programming load. For those searching for a something lighter, and also open source, along comes Sparkplug.
Cirrus Link authored the Sparkplug specification and provided it to the Eclipse Foundation, and several other companies support the group as founding members including Chevron, Canary Labs, HiveMQ, Inductive Automation, and ORing. Now additional companies are developing their products using Sparkplug for interoperability.
I recently received a paper authored by Arlen Nipper, president and CTO of Cirrus Link “Sparkplug: Open Source Technology to Bridge the OT-IT Gap”. He begins:
One of the primary pain points in Industrial IoT (IIoT) is disparate systems with both modern and legacy assets. Companies in any industry ranging from oil and gas to manufacturing can hardly imagine a world where they can choose any vendor’s hardware, plug it into their network, and have the hardware 100 percent self-discovered by their SCADA system and every application in the enterprise. True vendor interoperability for both data producers and data consumers is the vision, and new open-source technology may be the answer.
These days, everything relates back to digital transformation. Nipper write, Digital transformation requires devices in the field to be connected, with data made available that can speak the language of both OT and IT for improved business intelligence. In order for this type of digital transformation to be successful, data must be decoupled from a single application so it can flow to enterprise applications in a one-to-many approach.
From the first time I met Nipper, he has evangelized MQTT—a protocol he helped write—as an IT-friendly messaging protocol. It is lightweight. It is a publish-subscribe network protocol allowing for multiple data consumers.
MQTT is a messaging protocol. It does not describe the data traversing the wire (or air). While it provides an excellent engine for delivering IIoT data, MQTT doesn’t make the data interoperable across the enterprise. Thus, a new open source standard has been created and the IIoT industry should understand its importance for bridging the gap from OT to IT.
Nipper explains the next step:
The Internet expanded rapidly thanks to two open technologies – first HTTP, a data exchange protocol, and then HTML, which was used to define the data sent by HTTP. Both were needed. MQTT has needed its “HTML” for years in order for IIoT to explode in growth and adoption. In order to solve this problem of OT-IT interoperability, the Eclipse Sparkplug working group was launched in February 2020 to bring device communications standardization to IIoT.
The Eclipse Foundation states, “The Sparkplug Working Group was established to ‘improve the interoperability and scalability of IIoT solutions, and provide an overall framework for supporting Industry 4.0 for oil and gas, energy, manufacturing, smart cities, and other related industries.’ ”
Sparkplug is an open source software specification that provides MQTT clients with a framework to integrate data. The specification articulates three goals:
1. Define an MQTT Topic Namespace optimized for IIoT.
2. Define MQTT State Management to take advantage of continuous session awareness.
3. Define the MQTT Payload.
Sparkplug adds features including birth certificate and death certificate (session awareness) to help with contextualization of data.
Sparkplug makes this process fast, secure, and open standard so anyone can make use of the framework for MQTT interoperability. Many device manufacturers are supporting Sparkplug, which means it is built in natively on the device on the OT floor.
Nipper concludes:
With Sparkplug, machine learning and artificial intelligence applications can utilize the same standard interface for data without having to know and understand the entire OT environment. They can subscribe to the OT data, and use it immediately for IT functions.

• Enables telcos to monetize 5G networks and edge infrastructure by delivering new low latency cloud services at the edge via an app catalog
Remember two things if you meet the typical profile of a reader of this blog—it’s all happening at the edge and production/manufacturing are the edge; and data is the gold we’re mining and hype of the cloud is so over, it’s about gathering, analyzing, orchestrating, and sending all the data gathered at the edge to some sort of cloud.
I’ve been watching developments of 5G (and not so much WiFi6, but it’s a partner) for some time. It’s hard to separate the hype from reality—something that always happens at the early stage. Marketers can’t prevent themselves from trying to hype their companies as ahead of the curve, while engineers have been quietly pushing the curve.
So I was able to watch some sessions at the Hewlett Packard Enterprise (HPE) Discover Virtual Experience on this very topic. HPE’s Aruba is a leading supplier of communication products. Following is the lead announcement from last week.
HPE Edge Orchestrator, a SaaS-based offering enables telcos to deploy innovative new edge computing services to customers via IT infrastructure located at the edge of telco networks or on customer premises. With the HPE Edge Orchestrator solution, telcos can extend their offerings to include a catalog of edge computing applications which customers can deploy with a single click, across hundreds of locations. HPE Edge Orchestrator enables telcos to monetize the 5G network and telco cloud while bringing lower latency, increased security and enhanced end-user experiences to their customers.
Analysts expect the next decade to see the rise of edge computing where data intensive workloads such as AI, machine learning (ML), augmented and virtual reality apps will be hosted at the edge. Telcos already have thousands of edge sites powering mobile and fixed networks, so they are uniquely positioned to lead the edge services market. In fact according to a recent IDC study, 40% of enterprises trust their telco to be their main provider of edge solutions. However, until now telcos haven’t had the tools to do this themselves without relying on public cloud providers.
HPE Edge Orchestrator gives the power back to telcos. Now they can offer value-added edge services in their own right and can move from being primarily bandwidth providers to offering innovative edge computing applications, such as AI-powered video analytics, industrial automation and VR retail services. New revenue from these high-value enterprise services will also help to cover the significant cost of deploying new 5G infrastructure.
• Telcos can move from being primarily bandwidth providers to offering innovative edge computing applications
HPE Edge Orchestrator unleashes the deployment and configuration of customer applications, provided as virtual machines or containers, at geographically distributed edge locations owned by telcos, such as existing central offices or on customer premises. Customers can access edge applications via a self-service app catalog for simple management, monitoring and the deployment of an app to an edge device with one-click operation.
HPE Edge Orchestrator enables enterprises to easily combine their applications with network services offered by telcos, thus creating an end-to-end flow across the edge. Today, HPE Edge Orchestrator supports Multi-access Edge Computing (MEC) with other network-as-a-service (NaaS) functions being added to the catalog over time. The MEC platform enables applications to run at the edge, while delivering network services that ensure a dynamic routing of edge traffic in 4G, 5G, and Wi-Fi environments.
To capitalize on the edge services opportunity, telcos need to bring applications from the cloud out to the edge where the data exists. With HPE Edge Orchestrator, along with HPE Edgeline and ProLiant servers, telcos can position application intelligence at the edge and unlock major business benefits for their customers:
- Lower latency: When applications can process requests locally instead of routing them to a data center, they can deliver much better performance. This translates to a better user experience for any business application. For the new generation of ultra-low-latency use cases like augmented reality and industrial automation, short round-trip times are absolutely essential.
- Bandwidth optimization: Positioning application intelligence out at the edge, such as doing number-crunching closer to where the numbers are generated, greatly reduces the wide-area network (WAN) bandwidth the application requires. This translates to lower WAN costs for businesses and less traffic congestion in telco core and metro networks. Applications like video analytics become much more efficient and, as a result, applicable to use cases that might not have been viable in the past.
- Improved security and privacy: Any time businesses transmit data over a network, they’re potentially exposing it to security threats. For the most sensitive information, some businesses want to keep everything onsite. In regions with strict privacy protections like the European Union, some applications may simply not be viable unless they can process all personally identifiable information (PII) locally.
New edge computing offerings start with compute platforms optimized for deployment at remote operator sites (central offices, radio towers, other point of presence (POP) locations), or even directly at the customer premises. For example, HPE Edgeline Converged Edge Servers, such as the EL4000 and EL8000, have been specifically designed to run at the edge. Platforms like these host all of the components needed to manage the edge computing workloads in containers or VMs.
HPE Edge Orchestrator provides a centralized, comprehensive, hardware agnostic orchestration platform to provision, configure, and perform general management functions for all components of edge computing. HPE Edge Orchestrator is also multi-tenant by design.
Telcos can give diverse enterprise customers their own “private” interfaces to manage their workloads, sites, edge devices, and services, while their own teams manage the entire CSP edge computing portfolio as a single system. HPE Edge Orchestrator can also work in conjunction with the recently announced Aruba Edge Services Platform (ESP), enabling enterprises to easily integrate both Wi-Fi-based and telco services.

I picked this news item up from The Economist Espresso app.
For years, technologists have gushed about the promise of the “Internet of Things”, enabling ordinary objects—from kettles to cargo ships—to communicate autonomously with each other. The two essential technologies speeding the IOT’s arrival, inexpensive sensors and super-fast networking kit, are advancing rapidly. Gartner, a research group, predicts that the global number of devices embedded with sensors will leap from 8.4bn in 2017 to 20.4bn in 2020. So is 5G, a telecoms-networking technology superior to today’s 4G mobile networks. But the world’s 5G system could split into two different and potentially incompatible entities. One has been developed by Huawei, a Chinese telecoms-equipment giant, at a cost of $46bn. But some are worried about the company’s links to the Chinese Communist Party. Several countries, led by America, have banned the use of Huawei’s gear in their systems for security reasons. The year 2020 could herald the arrival of the Splinternet of Things.
I daresay that most likely many countries in the world are concerned about the ability of the US government to monitor internet traffic through the technology of American companies. These swords always cut two ways when you take the larger view.
More relevant to this topic, though, could a potential splintering into two 5G systems globally impact IoT?
In the short term from what I can gather interviewing technologists, benefits from 5G will accrue from the ability for private, plant-wide broadband rather than from some global linking of sensors.
Perhaps we are a bit early for journalists’ raising fear, uncertainty, and doubt. Listening to people actually building out the technology, I think we are going to experience much benefit from 5G in the not-to-distant future.

Sander Rotmensen of Siemens automotive test center in Nuremberg, Germany and Yongbin Wei of Qualcomm recently discussed the birth of 5G networks for industrial applications. The occasion concerned the press release announcing implementation of a 5G private industrial network.
We’ve all heard about 5G and worries from a variety of national governments about whether another country is embedding spy firmware in its local company’s products. Personally, I think the worry is both silly and well-founded. Every country that houses a company in the market most likely has intelligence agents trying to do the same thing. (I could go into my university education and acquaintance with a professor with “former” CIA ties, but that goes too far afield.) And all companies will deny any tie.
And…we are going to use 5G because the benefits are great. A benefit everyone mentions is the ability to build private networks for a local facility. The network has very low latency and built-in 5-9s (99.999%) uptime.
And what are some of the use cases we can anticipate? Rotmensen and Wei provided a list of ideas:
- Mobile equipment (tablets, etc.)
- Assisted Workers (remote video/audio to experts, etc.)
- Backhaul depending upon geography
- Autonomous machines–robots, cobots with communication and low latency
- Autonomous logistics
- Edge computing, larger amounts of data with low latency
With the final release of IEEE Time Sensitive Networking still years away, 5G is looking very good. We are on release 15 presently. Release 16 is anticipated in June, 2020. With release 17, the increased capacity would easily handle pretty dense machine-to-machine and IoT applications.
First Private Standalone Industrial 5G Network
Showing the benefits of today’s trend toward cooperation and partnerships, this joint proof-of-concept network will explore the capabilities of 5G standalone networks for industrial applications.
The private 5G standalone (SA) network in a real industrial environment uses the 3.7-3.8GHz band. Both companies have joined forces in this project: Siemens is providing the actual industrial test conditions and end devices such as Simatic control systems and IO devices and Qualcomm is supplying the 5G test network and the relevant test equipment.
The 5G network was installed in Siemens’ Automotive Showroom and Test Center in Nuremberg. Automated guided vehicles are (AGV) displayed here which are primarily used in the automotive industry. New manufacturing options and methods are also developed, tested and presented before they are put into action on customer sites. This allows Siemens’ customers, such as automated guided vehicle manufacturers, to see the products interact live.
The Automotive Showroom and Test Center enables Siemens and Qualcomm to test all the different technologies in a standalone 5G network under actual operating conditions and to come up with solutions for the industrial applications of the future. Qualcomm Technologies installed the 5G test system comprising infrastructure and end devices in less than three weeks. Siemens provided the actual industrial setup including Simatic control systems and IO devices.
“Industrial 5G is the gateway to an all-encompassing, wireless network for production, maintenance, and logistics. High data rates, ultra-reliable transmission, and extremely low latencies will allow significant increases in efficiency and flexibility in industrial added value,” says Eckard Eberle, CEO Process Automation at Siemens. “We are therefore extremely pleased to have this collaboration with Qualcomm Technologies so that we can drive forward the development and technical implementation of private 5G networks in the industrial sector. Our decades of experience in industrial communication and our industry expertise combined with Qualcomm Technologies’ know-how are paving the way for wireless networks in the factory of the future.”
“This project will provide invaluable real-world learnings that both companies can apply to future deployments and marks an important key milestone as 5G moves into industrial automation,” said Enrico Salvatori, Senior Vice President & President, Qualcomm Europe/MEA. “Combining our 5G connectivity capabilities with Siemens’ deep industry know-how will help us deploy technologies, refine solutions, and work to make the smart industrial future a reality.”
The German Federal Network Agency has reserved a total bandwidth of 100 MHz from 3.7 GHz to 3.8 GHz for use on local industrial sites. German companies are thus able to rent part of this bandwidth on an annual basis and to make exclusive use of it on their own operating sites in a private 5G network whilst also providing optimum data protection. Siemens is using this principle to evaluate and test industrial protocols such as OPC UA and Profinet in its Automotive Showroom and Test Center together with wireless communication via 5G.
