As the management of manufacturing plants and other assets grows more complex, integrating automated monitoring of key performance indicators (KPIs) at the discrete level provides a built-in safeguard against unplanned downtime or consequential damages.
And it addresses one of the roadblocks many have discovered with a top-down enterprise-level path to IoT: the requirement for significant investments in infrastructure around equipment and business processes, with little ROI to show for it in the near term.
A detailed analysis by Accenture and GE revealed that in the Connect-Monitor-Analyze-Predict-Optimize continuum, companies reported a higher percentage of Analyze activity than Connect and Monitor over the course of IoT’s time in their industrial space. In an increasingly connected world, these findings point to an out-of-sequence disconnect.
They suggest that efforts to understand the voluminous amount of data have come before establishing the connected infrastructure needed for data-driven decision making – and well before making a coherent business case for the data collection. In other words, the raw data available often has not been connected to the specific insights required.
The discrete IoT approach to ROI
Discrete IoT views a large machine asset as a collection of systems and subsystems with data onboard that can be given a voice with sensors, and deliver ROI in short order. Every subsystem contributes to the overall performance of an asset, and knowledge in that subsystem can be harnessed to assess its health or predict its failure. Consider which products in a motion control subsystem could provide safety, reliability and productivity insights. Pumps, actuators, valves, and filters all contain current-state performance and diagnostic data.
Having a current-state view of machine health is better than nothing, but simply publishing it on a dashboard screen stops short of being able to optimize a system or a process. The greatest power of IoT stems from the ability to perform historical analysis with time-series data, whether it be KPI-driven alerts and alarms to maintenance personnel; profiles and trend curves that pinpoint root causes of failures; or notifications to ordering systems. One primary goal is to be able to examine the conditions preceding work orders, unplanned downtime or other failures as data is correlated and presented on user-friendly interfaces that make the decision options very clear.
What is the sensor?
In motion control subsystems, pumps, actuators, valves, and filters all contain current-state data about a machine’s health that can be inspected, unlocked and sent from the equipment to a decision-maker via networked, wireless sensors. A sensor converts a physical condition such as air pressure, in-line and ambient temperature, flow or vibration into an electrical signal capable of being analyzed via the cloud or local applications for a manufacturing system.
Sensors are plugged into a machine’s existing ports or through a custom integration, and trigger alerts or alarms when tied into a control system or gateway programmed to observe when thresholds for defined performance parameters are exceeded. In this way, plant professionals can safeguard the peak performance of their operations.
With today’s wireless sensors and powerful software, it is possible to:
Notify responsible parties of an event requiring preventative or corrective action through text alerts
View real-time actionable data in graphical form from a dashboard
Export data for further analysis of historic trends to any internet-connected device

The ever-changing industrial Internet of Things has revolutionized the traditional landscape and business model of the construction machinery industry. Domestic and foreign parts and service providers have increased their investment and continuously launched innovative products and technical solutions based on the industrial Internet of Things.
From November 27th - 30th, 2018 Parker brought its Voice of the Machine™ industrial IoT platform to the Shanghai Bauma Exhibition. The technology covers the "last mile" of discrete IoT with a focus on interoperability, security and scalability.
In addition, Parker’s booth featured four models to fully demonstrate the powerful and comprehensive traditional hydraulic technology, covering the cab control system, chassis drive system, vehicle implement system and engine power system.
"Aligned with the new industrial landscape brought by the industrial Internet of Things, Parker created a breakthrough platform, Voice of Machine, to deliver connected products and systems. Our system integration capabilities will help address the increasingly demanding application needs of customers worldwide."
Hou Yifei, president of Parker’s Transmission and Control Group, Asia Pacific
Covering the "last mile" of the Industrial Internet of Things
At present, Internet of Things technology focuses on enterprise-level solutions, but the key component data identified and collected by the enterprise-level Internet of Things is only 10%, which greatly limits the potential of mechanical equipment to predict failures and optimize performance. Discrete IoT can deliver the remaining 90% of the core component data, which is the "last mile" that the Industrial IoT does not reach.
To this end, Parker initiated a centralized strategy to ensure that all IoT-based products and systems use the same communication standards and best practices to deliver interoperability, security, scalability and visibility.
An ecosystem of connected products and services
Through the Voice of the Machine online platform, users can interface with products, systems and professional engineers to ensure global monitoring and asset management for critical system operations.
Both IQAN® and PTS are software products based on the Voice of the Machine platform, which was also unveiled at the Shanghai Bauma Show. IQAN® Interconnect Software integrates intelligent hydraulic components and electronically controlled hardware and software to optimize device performance and simplify remote monitoring.
No matter where you are, users can use the IQAN® Interconnect Software to remotely diagnose vehicle faults and learn about current performance status through the Parker Vehicle System Gateway. IQAN® Interconnect Software provides a large number of standard function modules and a custom configuration interface. It features an adaptive web interface, which is convenient for users to view from multiple channels such as a PC, tablet or mobile phone and can easily publish data to the cloud.
The PTS Parker Tracking System is an asset management solution for critical wear components. The PTS software records detailed information about parts and assets, and users can connect to the Internet for secure access from multiple sources. The PTS generates a unique identification code printed on the barcode or RFID tag for each hose assembly.
Record and extract hose information through barcode and RFID traceability system to quickly, regularly and accurately perform equipment maintenance and repair, reducing downtime of engineering equipment. PTS can also establish an asset location database, customize inspection templates, store retrieval history inspection results, and set up scheduled maintenance reminders.
Improve system integration capabilities of traditional hydraulic technology
The EcoReach forklift assembly system is the highlight of Parker’s traditional hydraulic technology. The electric forklift is usually handled by an electro-hydraulic system. The powertrain consists of a series of separate components: an inverter that converts battery energy into alternating current; an induction motor that outputs torque and speed; and a hydraulic pump that provides flow and pressure; and a hydraulic system controls the valve block to control the flow and pressure of the required hydraulic function.
The EcoReach Forklift Assembly System integrates and optimizes these components to improve performance and efficiency, extend battery life and increase loading and unloading speed. The Parker Hannifin EcoReach Forklift Assembly system uses a fully integrated electro-hydraulic system assembly that plugs and uses to minimize the complexity of upgrading the forklift through the EcoReach system.
A large number of test results show that the system brings great potential benefits: the time to stabilize the oscillating load is reduced by 60%, the handling efficiency of the operator is improved, the time required for the entire lifting cycle is shortened, the production efficiency is increased by 13%, and the energy consumption of the entire lifting cycle is reduced by 48%. If you use the same battery to charge, the electric forklift works longer.

It seems like every industrial company is at some stage of planning for or deploying industrial Internet of Things (IoT) technology. According to a survey of IoT decision makers and influencers in the manufacturing, oil, and gas, and transportation industries by Bsquare for their 2017 Annual IoT Maturity Survey, 86 percent of participants had adopted IoT solutions. Almost all believed that the technology will provide a significant or tremendous impact on their industry.
Yet, while there is certainly good news on the IoT front, you can also find plenty of articles suggesting that IoT adoption is proceeding slower than many expected. A 2017 Cisco study found that 60 percent of IoT initiatives stall at the Proof of Concept stage and only 26 percent of companies considered their IoT initiatives a complete success.
The difference in those two surveys may result from who was surveyed. For their report, Bsquare surveyed “experienced, senior-level IoT decision makers” in select industries with a well-defined IoT value proposition, while the Cisco report was based on a broader survey of IT and business decision makers.
Still, there is no denying the complexity of deploying IoT broadly. It requires installing sensors or replacing legacy equipment with IoT-enabled equipment, as well as an implementation of software to support sensor management, data collection and visualization and, in some cases, machine learning. Plus, many organizations will need to address the skill gap that currently exists in the areas of IoT implementation and management.
All of that makes the move from small pilot programs, where conditions and unexpected consequences can be carefully managed, to broad deployments one of the most significant challenges we face as an industry.
Planning for scale
If you are coming off a successful pilot, you have proven the technology based on your use case and have the opportunity to build on that momentum to make a significant, positive impact on your business. Capitalizing on that opportunity starts with conducting a thorough capability and needs assessment across functional departments. Based on this assessment, you’ll need to assemble a dedicated cross-functional team to plan for and manage the deployment.
There are two factors I want to emphasize in regard to that team. First, collaboration across the business, particularly IT and OT personnel, along with engaged executive sponsorship, is crucial to a successful deployment. Second, don’t hesitate to bring in consultants and partners as needed. As the Cisco survey found, “organizations with the most successful IoT initiatives leverage ecosystem partnerships most widely. They use partners at every phase, from strategic planning to data analytics after rollout.”
One of the first questions this team must address is, what exactly does scale look like for our organization? Be clear and set expectations with executive sponsors and division leaders on what success looks like and what is required to achieve it.
This is where an IoT planning framework becomes a powerful tool. There is the experience to be gained from other adopters, but there is no off-the-shelf plan you can plug into your organization. The framework I’ve found most effective is one built around the five core components of an IoT solution. These include:
The “things” that will generate data.
How those things will be connected to the internet.
How data from those things will be collected.
Where that data will go.
Who is responsible for managing the data.
It sounds simple, but this framework can impose the necessary discipline to minimize unexpected consequences, ensure consistent collaboration and support the successful transition from limited to broad deployment.
Planning and managing the deployment
Once you have your team and framework, it’s time to begin planning the deployment. In terms of the things that will be generating data, you need to gain an understanding of their shape, operating specifications, and environmental limits. Where do sensors currently exist and where do they need to be added? For sensors that need to be added, is the most economical choice to retrofit legacy equipment or replace that equipment if it is already approaching the end of its functional life? Carefully analyzing the specific requirements of your things during the planning stage can save huge amounts of time and hassle later in the process.
The same is also true for connecting things and collecting data. This is one of the areas where collaboration between IT and OT personnel is essential. Identify exactly who from each group will be required to support the installation and commissioning and the time commitment required. Also, develop contingency plans for addressing equipment failure so you can react to those situations, if they occur, in a controlled manner that minimizes consequences.
Another important consideration is opening communication channels with on-site personnel. If they aren’t on board with the plan, the chances for success are diminished. As with any new technology, you may face resistance and skepticism, and this should be addressed early in the process.
When you’re ready to begin the deployment, the same framework used for planning can be employed. In terms of things, the challenge shifts from defining requirements to managing logistics. Who is responsible for ensuring the sensors, equipment and other technology required to support the deployment get where they are supposed to be when they are supposed to be there? The complexity of this task should not be underestimated, particularly for multi-site deployments.
This same challenge extends to the human resources required to support the “connect” and “collect” functions of the framework. Do you have the installation resources lined up, contracts in place and wiring diagrams harmonized?
Deployment is also an additional opportunity to connect with on-site resources to reinforce the why behind the new technology. Again, human factors play a key role in the success of IoT and should be addressed at every stage. Finally, take the time to practice the contingency plans you developed during the pre-deployment phase.
As you move into the post-deployment, this framework allows you to address key questions associated with system health monitoring, the integrity of data collection and internet connectivity systems and who is responsible for each, how results are reported to various stakeholders and who makes decisions about changes to the system.
Crossing the bridge
The challenge of moving from a successful pilot program to a broad deployment can be daunting and shouldn’t be undertaken lightly. But, if you have identified high-value use cases it is one that must be addressed. Developing a deployment framework that considers things, connectivity, collection, learnings and action at each stage can help impose discipline across the process and increase the likelihood of success.

As a company that has produced motion and control components and subsystems in core industrial sectors for 100 years, Parker has recently taken a significant step forward by embarking on a digital transformation. Between our own journey and working with customers seeking to leverage the Industrial Internet of Things, we’ve arrived at certain truths about the process of building digital ecosystems of connected products. One of those truths is that an effective enterprise of connected “things” must have oversight and buy-in from a broad spectrum of stakeholders.
A culture of silos has no place in a digital transformation
Going digital affects too many aspects of an organization, often in ways that only become apparent later on. That’s why it makes sense to marshal perspective and talent from every corner of the enterprise when determining how best to participate in what has essentially become another Industrial Revolution.
At its most simplistic, deploying IoT effectively can achieve two things for your organization: improve your ability to save money, or improve your ability to make money. That’s the power of understanding the health of your machine assets before they break down, and carving out a market advantage based on the intelligence provided by connected devices. The decision to move into this realm requires a clear-eyed assessment of where your business is now, and where you want it to go, with input from everyone whose functional experience would or could be altered as a result of that transformation.
For example, if your responsibility is to ensure the highest level of uptime and safe operation for a fleet of off-highway work trucks or an entire manufacturing organization of factory assets, you know it would be valuable to have parts and components in that equipment enabled to alert you when service or replacement is needed. So you would want to be sure that the enterprise was selecting a parts supplier with the ability to design, manufacture, integrate and easily service such components – a partner rather than a vendor, essentially. That would involve a meaningful conversation with colleagues outside of the operations silo.
Procuring the solution is just the beginning
But what about managing the never-ending data stream created as a result of liberating the information contained within the now-intelligent parts? Can you integrate it with other databases to generate insights and drive value? What about data security and privacy? Do you have people with the right skills working for you now; can they be trained or should new talent be recruited? What about paying for all of this?
These questions and many more inform what should become part of an ongoing cross-functional conversation within the enterprise. The idea of 24/7 connectivity can be very appealing, but the key to success is having a well-thought-out strategy to tie connected products to your specific core business and deliver those solutions to the end users who can benefit from them. That only comes from having a diverse group that is well informed and connected to the process because its members fully appreciate the stake they have in it.
Our IoT roadmap to success started with customers
Our near-term IoT objective for our own OEM customers was to provide better reliability and higher performance for the components and systems they source from us (such as pumps, hoses, connectors). Built on a common platform, our IoT-empowered solutions all recognize and communicate with each other, simplifying deployment. The resulting Voice of the Machine offering makes it possible to identify what we call a serviceable event, determine the recommended next steps, and through our ebusiness capability, make it easy to remedy. That is Parker’s play in this stage of the evolution of the IoT revolution.
In our case, engaging expertise across the company when we began our journey was a nuanced process of change management. We had a lot of leaders already who had to be brought along because, while the focus in IoT may initially emphasize the “build” part of a new solution, the “operate,” “sell” and “service” elements of the solution are critical for a company like ours.
That meant engaging our head of sales, CIO, the tech office and the P&L executives closest to the customer. Providing the support they need to achieve alignment means something different to each of these functions. To deliver on the promise of true collaboration that we ascribe to at Parker, we maintained close working relationships and a high degree of transparency as we worked on what our smart product offering would ultimately look like. And it remains a living, breathing organism to this day.
So what is the digital strategy to be for your company? What current and future customer use cases should you be envisioning today to improve your customers’ experience and who in your organization should be involved in shaping those experiences? It will never be too late to get the conversation started.

Last year, PwC found that 85 percent of U.S. manufacturers are already delivering, or planning to deliver, products with IoT capabilities. Considering the promise of IoT, this should come as no surprise.
Manufacturers, including Parker, are moving quickly to IoT-enable their products because of the exciting new capabilities IoT technologies deliver. For example, equipping off-road industrial equipment with telematics systems that send data to a centralized fleet management platform provides the visibility fleet operators need to increase equipment utilization, reduce maintenance costs and increase safety.
Similar benefits are available for in-plant equipment. When subsystems, such as pumps and power units, are factory-equipped with sensors and network connectivity, plant operators suddenly have the visibility they need to improve efficiencies and reduce downtime.
Delivering value in manufacturing
Deployed broadly, these capabilities deliver significant value in manufacturing. In fact, according to McKinsey, factories and other production environments have the potential to realize the biggest financial impact from the application of IoT. They predict the IIoT will generate an economic value of between $1.2 trillion and $3.7 trillion by 2025. This value will be created through new energy efficiencies, labor productivity, inventory optimization, and improved worker safety.
But, what happens when these IoT-enabled systems take their place alongside legacy systems? Do plant managers and engineers risk creating islands of intelligence within their plants that leave out the legacy systems that make up the bulk of their equipment and limit the return on their investment in IoT infrastructure? Or, will they be forced to replace critical legacy systems prematurely to expand the reach of their IoT initiatives?
Fortunately, the answer to both of these questions is no. “First-fit” – meaning components or subsystems that have intelligence and connectivity designed into them – still receive the lion’s share of the attention when it comes to the future of IoT. However, in many cases there is an opportunity to retrofit legacy devices with IoT technology to allow them to take their place alongside first-fit components in smart machines and processes. In the short term, these retrofit opportunities may prove even more valuable than first-fit opportunities because they can be applied to aging equipment with a higher risk of failure or inefficient operation.
For example, air compressor inefficiency is a common source of wasted energy in manufacturing. New air compression systems have sensors designed into them that allow leaks within the system to be identified to eliminate inefficiencies. But legacy systems can also be instrumented with similar sensors to achieve the same objective.
Key to success of IoT retrofits
Key to the success of legacy system IoT retrofits is the ability to integrate the data from the retrofitted system with other systems, both new and old, to simplify IoT management. This is one of the values of the discrete approach to IoT provided by Parker’s Voice of the Machine™.
It allows each system to act as a standalone application through the Voice of Machine cloud platform and user interface. It also allows the data from the component or subsystem to be delivered to an existing cloud platform through cloud and edge-based integrations and presented in context with other machine data, regardless of whether that data was created by a Parker component or a component from another manufacturer.
In today’s increasingly connected world, it seems short-sighted to not have IoT capabilities included in new equipment that is being installed in either brownfield or greenfield environments. However, it’s also very limiting to restrict IoT to only new components or subsystems, particularly those whose operation have a significant impact on operating costs or productivity.
Parker and its distribution partners have the IoT expertise and toolset to help you develop a plan that focuses IoT on the systems or components where the greatest value can be realized, new or legacy, and create an integrated solution that maximizes return on investment.
