In 2013, the UK Government Office for Science produced a report, entitled the Future role for energy in manufacturing. In this report, they identified two threats to UK-based manufacturers. The first was that the price of energy in the UK will rise, compared to the cost faced by competitor firms abroad, placing UK manufacturers at a significant disadvantage. Well, the price has risen but globally because of the Russia Ukraine war. Nevertheless, the threat to UK manufacturing is still valid. The second threat is that a low-carbon electricity supply will be unreliable, and that the cost of power cuts will rise. Well, that is certainly true if you rely solely on low-carbon electricity. But using multiple sources of power can be greatly beneficial.

The PSM system can be used for applications such as:

• Electrical power consumption monitoring and reporting
• Fault monitoring
• Generator control features for generator to power grid synchronization
• Demand penalty cost reduction/load shedding

The PSM system consists of:

• PSM module – A standard IC694 module that mounts in an RX3i main rack. The PSM module provides the DSP capability.
• Terminal Assembly – A panel-mounted unit that provides the interface between the PSM module and the input transformers.
• Interface cables – Provide the GRID 1 and GRID 2 connections between the PSM module and the Terminal Assembly

The image below shows how a basic PSM system can be connected.

PSM System Features

• Uses standard, user-supplied current transformers (CTs) and potential transformers (PTs) as its input devices.
• Accurately measures RMS voltage and current, power, power factor, frequency, energy, and total three-phase 15-minute power demand.
• Provides two isolated relays that close when the voltage phase relationships between the two monitored grids are within the specified ANSI 25 limits provided by the RX3i host controller. These contacts can be used for general-purpose, lamp duty or pilot duty loads. Voltage and current ratings for these load types are provided in GFK-2749, PACSystems RX3i Power Sync and Measurement System User’s Manual.
• Provides a cable monitoring function that indicates when the cables linking the PSM module and Terminal Assembly are correctly installed.
• PSM module and Terminal Assembly are easily calibrated by hardware configuration using the PAC Machine Edition (PME) software.

Since the beginning of the COVID-19 pandemic, businesses across the UK have faced a surge in cybercrime. In fact, research indicates that UK businesses experienced one attempted cyberattack every 46 seconds on average in 2020. Industrial businesses are a prime target for hackers and the ramifications of a data breach or denial-of-service attack are far-reaching, making system security imperative. Here, David Evanson, corporate vendor relationship manager at Novotek UK and Ireland, explains how industrial businesses can keep their vital systems secure.

For many business leaders and engineers, it is still tempting to consider large multinational companies or data-rich digital service providers to be the prime target for hackers. However, the growing volume of cyberattacks on businesses globally show that any company can be a target of malicious attacks on systems and services.

According to research by internet service provider Beaming, there were 686,961 attempted system breaches among UK businesses in 2020, marking a 20 per cent increase on 2019. Of these attacks, Beaming noted that one in ten intended to gain control of an Internet of Things (IoT) device — something that indicates a tendency to target system continuity rather than conventional data.

Both factors together are cause for alarm among industrial businesses of all sizes. Hackers are targeting all manner of companies, from start-ups to global organisations, and focussing more on the growing number of internet-connected devices and systems that were previously isolated.

The consequences of a device being compromised range from data extraction to service shutdown, and in any case the financial and production impacts to an industrial business are significant. There is no single quick fix to bolster cybersecurity due to the varying types of hacks that can take place. Some cyberattacks are complex and sophisticated; others less so. Many attacks on devices tend to fall into the latter category, which means there are some steps industrial businesses can take to minimise risk.

Novotek has been working closely with industrial businesses in the UK and Ireland for decades. One common thing that we have observed with automation hardware and software is that many engineers do not regularly upgrade software or firmware. Instead, there is a tendency to view automation as a one-off, fit-and-forget purchase. The hardware may be physically maintained on a regular schedule, but the invisible software aspect is often neglected.

Older firmware is more susceptible to hacks because it often contains unpatched known security vulnerabilities, such as weak authentication algorithms, obsolete encryption technologies or backdoors for unauthorised access. For a programmable logic controller (PLC), older firmware versions make it possible for cyber attackers to change the module state to halt-mode, resulting in a denial-of-service that stops production or prevents critical processes from running.

PLC manufacturers routinely update firmware to ensure it is robust and secure in the face of the changing cyber landscape, but there is not always a set interval between these updates.

In some cases, updates are released in the days or weeks following the discovery of a vulnerability — either by the manufacturer, Whitehat hackers or genuine attackers — to minimise end-user risk. The firmware version’s upgrade information should outline any exploits that have been fixed.

However, it’s important to note that legacy PLCs may no longer receive firmware updates from the manufacturer if the system has reached obsolescence. Many engineers opt to air-gap older PLCs to minimise the cybersecurity risk, but the lack of firmware support can also create interoperability issues with connected devices. Another part of the network, such as a switch, receiving an update can cause communications and compatibility issues with PLCs running on older versions — yet another reason why systems should run on the most recent software patches.

At this stage, engineers should invest in a more modern PLC to minimise risk — and, due to the rate of advancement of PLCs in recent years, likely benefit from greater functionality at the same time.

Firmware vulnerabilities are unavoidable, regardless of the quality of the PLC. At Novotek, we give extensive support for the Emerson PACSystems products that we provide to businesses in the UK and Ireland. This involves not only support with firmware updates as they become available, but also guidance on wider system resilience to ensure that businesses are as safe as possible from hardware vulnerabilities. The growth in cyberattacks will continue long beyond the end of the COVID-19 pandemic, and infrastructure and automation are increasingly becoming targets. It may seem a simple step, but taking the same upgrade approach to firmware that we do with conventional computers can help engineers to secure their operations and keep running systems safely.

In the age of connectivity, there is no shortage of useful information that engineers can leverage to optimise and improve operations. Everything from the speed of motors to the weather forecast can influence production. However, bringing these data sources together in a secure way is a challenge faced by many engineers. Here, George Walker, managing director of Novotek UK and Ireland, explains how engineers can bridge the gap between local process data and external data sources.

The Internet of Things (IoT) may still be a relatively new concept for many consumers and professional service businesses, but the idea of machine-to-machine communication and connectivity is nothing new for industry. In fact, it’s been more than 50 years since the programmable logic controller (PLC) first became popular among industrial businesses as a means of controlling connected systems.

The principle behind the PLC is quite simple: see, think and do. The controller will ‘see’ what is happening in a process based on the input data from the connected devices and machines. The PLC then processes this input and computes if any adjustments are required and if so, it signals these commands to the field devices. Traditionally, the field devices that could be controlled was limited, but recent developments in sensor technology have made specific components and resources much more measurable.

For example, if a water tank is almost at full capacity in a food processing plant, data from connected sensors can feed that information to a PLC. The PLC then sends the signal for the valve to close once the water volume exceeds a certain threshold, which prevents overflow. This is a simple control loop that sufficiently meets the need of the process.

Unfortunately, even as edge computing and PLC technology has advanced and offered more sophisticated data processing and control at the field-level, many plant engineers continue to setup their devices in this way. In reality, modern edge devices and industrial PCs (IPCs) are capable of providing much greater control, as well as responding to external commands or variables that were previously beyond the scope of control systems.

The outer loop

While the idea of the Industrial IoT (IIoT) is predominately a means of branding modern connectivity, the wider Industry 4.0 movement has brought with it some valuable advancements in edge and PLC technology. Among these advancements is the potential for on-premises automation and control systems to not only connect with local devices in an inner loop, but to draw from external sources: an outer loop.

The outer loop can take several forms, depending on what is most applicable or relevant to a process or operation.

For example, some more digitally mature businesses might have outer loops that feature an enterprise resource planning (ERP) system, supply chain management software or a wider manufacturing execution system (MES). These systems will share and receive relevant information or send required adjustments — such as due to raw material intake or low stock — to an edge device, which feeds into the inner loop. This allows industrial businesses to make use of more comprehensive data analysis than can be achieved in local data systems.

Alternatively, an outer loop could draw from data sources that are completely external to a plant’s operations. For example, a wind farm operator could use an outer loop that drew from sources of meteorological data for wind forecasts. This could inform the optimum pitch and yaw of a turbine, controlled by a field device.

Another example, and one that will resonate with many industrial businesses, is energy price. The cost of power from the electrical grid fluctuates throughout the day, which might mean that on-site generation — such as solar panels or heat recovery processes — become more economical during times of peak grid demand. An outer loop can communicate this data efficiently to the relevant systems in a business, and changes can then be enacted that allow the business to reduce energy costs.

Establishing secure connection

Clearly, there is a benefit for industrial businesses to establish both inner and outer loops. However, there is one barrier to deployment that most engineers encounter: hardware limitations.

Traditional PLCs were designed in a rather utilitarian manner to complete control functions effectively and in a straightforward manner. This no-frills approach persists even with modern PLCs — even with today’s technical specifications, most PLCs are not designed in a way that struggles to handle much more than a real-time operating system and some control applications.

Attempting to set up such a PLC to interact with an outer loop would either not work at all or severely hinder performance and risk failure.

Engineers can tackle this problem by introducing a separate gateway device that serves as an intermediary between the outer loop and the inner loop. However, this is a somewhat inelegant solution that requires investment in additional devices, which will require ongoing maintenance and introduce yet another device into already large system networks. Across an entire site, this quickly becomes costly and complicates network topologies.

A better solution is an unconventional one. It is possible to set up a modern automation controller in such a way that it breaks the conventions of PLCs, as long as the device is capable of multi-core processing at pace. From Novotek’s perspective, one of the best modern units that meet this need is Emerson Automation’s CPL410 automation controller.

The CPL410 can split inner and outer loop processing between its multiple processor cores. The inner loop and PLC processes can run from a single core, while another core — or even a group of cores, depending on complexity — can run more sophisticated containerised applications or operating systems. Additional cores can broker between the inner and outer loops, ensuring reliability and security.

A multi-core setup is useful because it allows the PLC processes and gateway to be consolidating into a single unit, without compromising performance capacity or speed. It also means that ageing or obsolete PLCs can be upgraded to a controller such as the CPL410 during any modernisation initiatives, minimising additional capital costs.

Although the idea behind the IoT is not a new one for industrial businesses, the fact that other sectors are embracing the idea means more external data points than ever before are available. With systems in place that can support effective inner and outer loops, industrial businesses can leverage the increased connectivity of external markets and enhance their own operations.

It’s no secret that IPCs play an essential role in modern industrial operations. These vital units undertake a range of tasks, from managing equipment performance data to motion and automated system control. It’s therefore no surprise that the IPC market continues to go from strength to strength. In fact, ResearchAndMarkets forecasts that the global IPC market will grow at a compound annual growth rate (CAGR) of 6.45 per cent, to be valued at $7.756 USD by 2026.

IPCs feature prominently on the factory floor, generally either in control cabinets or mounted onto machinery. Being on the frontline means that engineers and plant managers know that, as a minimum, they need to specify ruggedised IPCs for their operations. What sometimes gets overlooked, however, is the operating temperature range of an IPC unit.

Electronic circuits and computing components are highly susceptible to extreme temperatures, be they high or low. At high temperatures, components can deteriorate faster. In the case of IPCs, modern CPUs are designed to prevent accelerated component deterioration by throttling their processing performance. This succeeds in reducing the heat produced in processing circuits, but it means that processes running on the IPC run slowly or become unresponsive — not ideal for real-time control applications.

In certain markets, considering operating temperature range is second nature for engineers. For example, an IPC tasked with controlling or collecting data from a welding robot will be specified to withstand high temperatures.

However, temperature should be a consideration even in unassuming industrial environments. If an IPC is situated outside, the exposure to sunlight — alongside reduced airflow in an installation — can cause an increase in temperature that can reach up to 70 degrees Celsius. Both Novotek and its partner Emerson Automation have encountered industrial businesses that have experienced this problem.

Of course, the solution to the challenge of overheating in IPCs is to specify a unit that boasts good thermal performance in an extended operating temperature. Unfortunately, not all IPCs that claim to offer this feature are actually effectively tested in conditions that accurately reflect real-world operating conditions, which can lead to some IPCs failing when deployed in the field.

The reason why extended temperature IPCs fail is due to the way that the testing is undertaken. In many cases, the IPC is tested in a thermal chamber that has significant forced air flow conditions, which reduces the efficacy and the accuracy of the test itself. A more effective way of testing is for the IPC manufacturer to block the airflow, which simulates a realistic use condition in a cabinet environment.

Emerson Automation conducts its tests under these restricted airflow conditions, which allows it to accurately demonstrate that its IPCs can perform at high temperatures without throttling processing performance. The company has even shared a video of its IPC thermal testing process, highlighting the capabilities of its RXi2-BP.

It’s for this reason that Emerson’s IPCs are the go-to option from Novotek’s perspective, because they ensure reliable and consistent operation in demanding environmental conditions.

With IPCs playing such a vital role in modern industry, its important that they are up to the task not only in terms of computing capacity, but also environmental performance. When plant managers and engineers can specify an IPC with assurances of the accuracy of thermal testing, it provides peace of mind that the unit can handle the heat.

According to a report by Gartner, the worldwide manufacturing industry will spend $561 billion on IT in 2018. Emphasis on digital transformation is driving this spend. However, businesses shouldn’t blindly invest in IT without aligning it to their business goals. Here, George Walker, managing director of industrial automation specialist Novotek,  explains.

Business goals and values are important for decision making. For instance, if a company’s business objectives focus on reducing waste, maintaining sustainability or reducing overheads, its manufacturing processes — and subsequent investment — should be defined with these specific goals in mind.

Consider American brewing company Anheuser-Busch as an example. In its 2025 US sustainability goals document, the business outlines a company-wide commitment to maintaining sustainability in its manufacturing processes. Among several other sustainability schemes, the brewer recycles its spent grain into bioreactors to be broken down by bacteria and turned into fuel. By doing this, the company saves money, reduces its carbon emissions and, vitally, remains in line with its company values and objectives.

But, how can manufacturers use new IT investments to help them achieve business goals? Efforts to reduce waste in production provides a good example of this. Let’s say a manufacturer hopes to increase its profits by reducing avoidable wastages in production. A sensible investment would be a data collection software that would allow the manufacturer to identify the six big losses in its facility — a term used to describe common reasons for productivity losses in manufacturing.

The best way to identify these losses is by using an IoT platform to collate and analyse data from processes across the factory floor. A perfect example is GE Digital’s IoT platform. When companies install an IoT platform to monitor their production, they could make some shocking discoveries. Unexpected wastes, such as breakdowns, faulty setups, idling, misalignment, defects in processes and start-up losses become apparent.

With Novotek, after installing an IoT platform, we carry out an analysis based on the six big losses. This allows you to measure and track all your wastages and understand their causes and effects. We would then be able to help recommend suitable fixes.

In the case of a quality defect, the IoT platform would identify if there were any problems, such as micro stops or changeover. Then, using six-sigma-based approach methods to rework processes to reduce waste could be identified. From this analysis, a detailed long-term IT solution can be formulated based on your company values and goals. There are indications from Gartner that manufacturing spend on IT will grow by a CAGR of three per cent through to 2022. It will be more important than ever to make sure IT investments carry forward fixes inline with your business goals and values. As the emphasis on IT focused fixes continues to grow, it will become vital to form cohesive IT strategies.

An annual report by Kaspersky Lab, The State of Industrial Cybersecurity 2018, revealed several interesting facts about how industrial cybersecurity is perceived by businesses and applied to Industrial Control Systems (ICS). The survey of 230 worldwide professionals reveals disconnections between what is feared by businesses, and what’s happening in reality.

For instance, 66 per cent of the surveyed businesses were most concerned about advanced persistent threats (APT), like data leaks and spying (59 per cent), because of their perceived potential impact. In reality, APT’s make up 16 per cent of cybersecurity incidents. Actually, conventional malware and virus outbreaks are becoming the greater problem. These attacks are not overly sophisticated and made up 64 per cent of cybersecurity incidents, last year.

Aside from misconceptions about the external threat landscape, disparities also exist within organisations. In relation to Kaspersky Lab’s survey, technology website tripwire.com cited a report by the SANS Institute. SANS found that, among nearly three-quarters of firms that were confident in their ability to secure their industrial internet of things (IIoT), there were more likely to be different internal perceptions about the effectiveness of their security measures. While leaders and department managers were more likely to have a “rosy outlook” of their security, operational technology departments had a more pessimistic view.

Such misconceptions would be even more of a concern within critical national infrastructures. Cyberattacks against water, energy or chemical supplies can have very real consequences for countries and their populations.

Upgrading control systems

From a hardware and systems perspective, more than half — 54 per cent — of the surveyed businesses identified integrating ICS with IT systems and Internet of Things (IoT) ecosystems as among the most pronounced challenges. This last statistic places a wider challenge faced by plant managers into a whole new context: specifically, how best to achieve space and cost savings by reducing the size and complexity of plant equipment.

Plant managers are turning to new systems to achieve greater levels of flexibility and profitability in their production. This coincides with older programmable automation controller (PAC) systems, like trusted Series 90-30 controllers, reaching the end of their operational lifespans. In many cases, these 90-30 systems have been relied upon as integral to plant operations for upwards of 25 years.

How can plant managers effectively upgrade their systems, while ensuring that cybersecurity measures keep up with the rate of technology adoption — and the external threat landscape? Fortunately, answers lie in smart hardware and its role in helping manufacturers enhance process flexibility and performance.

Centralised security

One solution lies in better control. The RSTi-EP CPE100 is a compact controller for PAC systems — specifically, to control the RX3i CPU from Emerson which has emerged as a popular and effective upgrade for 90-30 systems. In a nutshell, the RSTi-EP CPE100 leverages the power and flexibility of PAC systems in smaller applications.

The RSTi-EP CPE100, entire PAC systems can be programmed in stand-alone applications, or the system can be used as an auxiliary controller in larger process applications that use the RX3i. Not only does the system leverage the power and flexibility of PAC systems in smaller applications, there are also benefits in terms or cybersecurity — indeed, the RSTi CPE100 is secure by design.

With the system, companies can apply optimised security right from the very start. RSTi CPE100 incorporates technologies like Trusted Platform Modules and secure, trusted, and measured boot. It allows centralised configurations, so that encrypted firmware updates can be executed from a secure central location. Specifically, a suite of cybersecurity technologies can help prevent unauthorized updates. Meanwhile, built-in security protocols can protect against man-in-the-middle attack (MITM) — where the attacker secretly inters with communications between two parties — and denial-of-service (DoS) attacks.

Speaking of the “man-in-the-middle”, another key takeaway from Kaspersky Lab’s report is that, going forward, industrial companies must also pay more attention to employees’ understanding and awareness of cyber threats. Because the RSTi-EP CPE100 can streamline application development and integration, a further benefit of the system is that it simplifies training for operators and maintenance workers.

While cyberattacks on ICS computers are misunderstood by many within industry, it’s necessary to overcome these misconceptions while keeping up with the best cybersecurity measures. Novotek recommends that managers should pay attention to system security from the very beginning of their integration. The more critical the application, the more important it is that ideas surrounding cyberattacks accurately pre-empt the realities.

Digital transformation has become a goal for many businesses in the industrial sector, as automation technologies develop and the fields of information technology (IT) and operational technology (OT) converge. However, digital transformation is also an ambiguous concept to strive towards without a clear strategy. Here, we speak with Richard Kenedi, senior vice president of manufacturing at industrial software provider GE Digital, and George Walker, managing director of industrial automation expert Novotek UK, about the ideal path to industrial digital transformation.

GE was one of the first to make serious investments in digital technology and was arguably the first digital industrial provider. What are the key lessons learned from the GE that you would share with other industrial companies?

Richard Kenedi (RK): “The first is focus. You have to know your customers and how you can best help them. It’s not about the technology, it’s about solving the problem. I think secondly, it’s about attitude. We’ve learned that customers aren’t looking for a hero to save them, they want a guide to help them solve a problem today and see around the corners for tomorrow.

“Thirdly, it’s critical to have deep domain expertise when it comes to the people, processes and technologies of each industry we serve.

“In every industry, there are organisations that are implementing at the edge of technology and others that are slower in adoption. Each organisation is at its own individual point of digital transformation maturity. Issues range from culture to investment to workforce. Digital transformation is critical but planning and implementation can’t slow ongoing production. Each company needs guidance to approach digital transformation in a way that meets their holistic situation and requirements.”

For Novotek, as a GE partner in the UK and Northern Europe, you’ve been helping businesses digitalise and increase automation in their operations for some time. What are some of the common challenges when starting that process?

George Walker (GW): “As with any early stage technology, a lot of people initially struggle to separate the hype from the practical reality. Digital transformation, Industry 4.0 and digitalisation have becoming industry buzzwords in the past few years, with a lot of companies promising the Earth if a company installs its latest widget. Often we find companies want to digitally transform, but don’t have a clear picture of why or what they’re looking to achieve.

“The reality is all these concepts are a means to an end — they shouldn’t be the goal in themselves. The end goal might be improved productivity, higher throughput, reduced downtime or lower operating expenditure. Digital transformation is the vehicle that gets industrial businesses to that destination, and the systems that are required as part of that depend on the company’s specific outcomes, focusses and current operations.”

Often, IT providers claim their offerings can digitalise the manufacturing space. What is the difference between an IT and OT setting and why do you see a need for purpose-made software in the manufacturing space?

RK: “IT and OT have come a long way in convergence. In many cases, we’ve evolved from the boundaries and barriers of the past to greater collaboration. IT has gained respect for the real-time needs and process domain expertise of OT. OT has gained an appreciation for IT’s capabilities such as security and mobility. The people and the systems have to work together.

“Purpose-made software has been important for decades. Build-your-own solution is costly, and now more than ever, with our aging workforce retiring, the knowledgebase that continued to drive and support do-it-yourself solutions is becoming unavailable. Most organisations understand the risk that they’re taking on by considering do-it-yourself today. 

“In contrast, purpose-made, out-of-the-box software provides a long-term solution with on-going innovation, maintenance, and support. Companies benefit from focussed development and best practices. For example, these out-of-the-box solutions help industrial companies support the reality of an operator’s job on the ground all the way to the plant manager, and even for global operations directors. You need to understand the failure modes and the success modes for their processes, and you need to understand how that translates into different KPIs across the organisation – for example, how OEE impacts revenue, or even new technologies.”

GW: “From our side, the biggest disadvantage of IT providers trying to fit corporate software into industrial settings is that although IT and OT are closely interlinked and complementary, they are still fundamentally different. These clear distinctions, between the environments in which they are used, mean that companies with comprehensive experience of serving industrial markets will always be better equipped to meet the needs of manufacturing software.

“GE, for example, is uniquely positioned due to its extensive history in the industrial space, as well as in digital technologies and software. Similarly, Novotek has worked closely with industry for many years and have developed modules and systems in response to industry issues and opportunities. This means we can both ensure that our software is built around the needs, wants and requirements of industrial environments, rather than being retroactively reshaped to meet a market brief.”

How does GE see itself differentiating itself from its competitors?

RK: “We are more focused on our target markets and industries, because these are the places where we believe we can best help our customers win. In those areas, it’s really about simplicity, speed and scale. Simplicity – because we’re investing across all our product lines to make it easier than ever for customers to adopt and adapt our technologies for their needs. That goes for user experience in the field, through to no-code rapid application development visualisation tools like Proficy Operations Hub.

“Speed – because really customers want return on investment as quickly as possible, and they want responsiveness if they have a problem, and scale – because with our technologies, teams and our partners we are able to bring solutions to customers not only for one line or factory but for an entire enterprise globally. When we bring simplicity, speed and scale together for customers, that’s when you see truly transformative results.”

What are the ideal first steps an industrial business can take towards digitally transforming their operations?

GW: “The first step should always be to plan and identify what you want to achieve. For example, if your focus is on innovating to develop better products and find new ways of operating, this might lead you towards systems such as a modern manufacturing execution system (MES). The MES, alongside SCADA systems on the plant floor, allows for automated feeds of data through each level of an industrial business and insight into all processes.

“Likewise, a business who wants to reduce the frequency of maintenance or downtime might opt for  a Historian software that simplifies the collection, aggregation and analysis of data from equipment and operations. A specialist can advise the best systems to ensure the right results, if the business knows what its objectives are.

“This isn’t a decision to be made by one group within a company either. It’s important everyone, from the maintenance engineers to C-suite personnel, are involved in determining what the focus is to ensure buy in at every level. That way, you increase the likelihood that systems are introduced and set up to provide the insight each level of user needs, in the most effective way.”

50 years ago, the thought that a plant manager could stay home and be able to have meaningful oversight of operations, while collaborating with other remote colleagues on the details, was unbelievable. If COVID-19 had struck at that time, most factories would have simply closed entirely.

Today, instead, with the right industrial IT solutions, plant management — along with team supervisors, quality leaders, engineers and continuous improvement managers — can work as a team as if they were together, regardless of where they are. A combination of developments in IT and OT have come together to make this possible.

There are now ways to securely deliver existing automation software applications such as SCADA via the web. Likewise, plant data repositories, or Historian software, have had the speed and power of their collection and storage capabilities supplemented with modern, web-based tools for exploring data. This includes ways to quickly add context and description to otherwise technical data points, so there can now be one source of raw truth that is accessible from anywhere, comprehensible by anyone.

Full-fledged production tracking systems or MESs have similarly had rich web-based front ends built, so that the detailed flow of events and activities can be tapped into from anywhere, regardless of how those systems may have had to be tied to on-site automation and sensors

The driving force behind the evolution of plant tech, though, was to enable greater productivity. With information from core operations readily at hand, alongside information from the broader enterprise, leading firms began to accelerate their continuous improvement efforts, undertake deeper collaboration with suppliers and other industrial partners and develop better insights into how to refine products and processes. The fact that their modern systems lent themselves to remote work and collaboration would come to be seen as a bonus aspect to these capabilities.

Despite the ready availability of modern plant IT and automation, and the numerous documented cases of manufacturers realising the benefits of modern systems, many factories remain wedded to paper, spreadsheets and ad-hoc/as-able machine data analysis efforts (often based on manual extraction and collation of data from individual assets).  The implications of this go beyond it being comparatively inconvenient to deal with remote working.

Firms that have incorporated more modern plant solutions already enjoy significant advantages in their cost of production, their operational flexibility and their predictability in relation to meeting demand. The question is whether such current advantages will be further entrenched, or whether we will see a surge of investment from others to take on these capabilities. There is also a question of whether the firms catching up will look to go beyond simply sustaining their operations and towards fine-tuning or even re-shaping them.

Lessons from leading organisations

The next wave of technology adopters can benefit from observing how organisational structures and behaviours have been changed as modernisation has unfolded. New tech has certainly changed the way line-side operators stage, execute and manage production. However, the freer flow of data to different stakeholders has also seen improvement in surrounding business processes such as supply chain coordination and product design.

One of the cultural changes common in leading firms is broad recognition that detailed operational data supports the work of many stakeholders traditionally seen as removed from the production process. This has prompted the formation of cross-functional teams responsible for ongoing learning about the continuing evolution of automation and software.

Tasked with spotting developments that could yield outsize impact, not just sustain incremental gains in capability, cross-functional teams embody the recognition that technology is not only a critical tool to enable existing strategies, but potentially the key to new ones. That behavioural change also means that tech adoption is no longer intimidating or mysterious. With IT, operations, product design, engineering and quality leaders learning together, each group’s perspective and knowledge becomes part of a common understanding of how to understand the next technology wave in the context of the firm’s challenges and opportunities.

If the COVID outbreak showed how rapidly our steady work routines and supply networks can be disrupted, this is the time to see how technology can provide UK plc with increased resilience and a renewed operational vigour. It’s vital that manufacturers adopt the tools that support better insight and collaboration for the impact they can have on productivity, flexibility and even innovation. Modern plant systems should be seen as critical to success all the time, not just as a convenience during a pandemic.

Recently, I came across the concept of hyper-automation. While it initially sounds like a buzzword akin to the industrial internet of things (IIoT) and smart manufacturing, it actually means quite the opposite. It’s a term for operating environments that are bloated with automated, ‘smart’ systems making production excessively complicated.

This is particularly poignant because it speaks to a situation we have seen time and time again while serving businesses as Novotek UK and Ireland. Plants are increasingly becoming over-automated, with numerous systems installed to perform individual parts of a single process when a single system would accomplish the same thing. This doesn’t often happen with physical automated systems, but it’s a growing problem with industrial automation software and platforms.

Unfortunately, this problem doesn’t seem like it will be going away any time soon. It’s often not due to a lack of communication in an industrial business – although this is unquestionably a factor in some cases – as much as it is the result of the wrong approach to the latest industrial revolution.

For many businesses that Novotek UK and Ireland works with, the focus seems to be on obtaining IIoT-enabled widgets to achieve greater results, whether that be increased throughput, higher production rates or better energy efficiency. But because these systems are evaluated individually for payback and for technology choices, they form a patchwork network of equipment and systems that is expensive in its excessive complexity. Customers lose the chance to understand how they could use a common approach to defining key data requirements and to defining uses for data that cross functional boundaries – and this missed chance leads to overlap of systems and duplication of IT and OT spend.

Many successful adopters of digital technology typically work to become digitally-ready first. The process of becoming ready for digitalisation is generally about setting business objectives and working backwards to the tech that will enable them, while fostering a culture of innovation and collaboration so many stakeholders see how each other’s needs are really related. But in industrial environments, it’s often expressed as if digital readiness correlates to the amount of sensors, control systems and IIoT-enabled devices are installed.

For a leading industrial business to become digitally ready, the first step is identifying what you want to achieve. What is the end goal for the operational transformation? This could be a specified reduction in energy usage across a factory, or it could be an increased rate of production. With these goals in mind, leadership must consider what is currently stopping them from achieving this, whether it’s a lack of insight into key industrial processes or a skills shortfall.

Only once this is established can a business truly look at what systems can help. Fortunately, establishing these areas of limitation involves extensive communication with different aspects of the business, which means leadership can identify overlap between departments. This makes it easier to avoid investing in multiple systems that achieve the same thing.

Illustrating the challenge: Because Novotek UK and Ireland is an industrial automation specialist, we’re often called into businesses where we find there is overlap between the field service monitoring software and plant SCADA systems. These systems provide fundamentally similar performance insights from equipment, but neither the field technicians nor plant managers were aware of the other’s system.

The result of this is bloated networks and expensive, complex automation systems. This can be avoided simply by defining business goals first and working backwards from there, making technology an enabler rather than an emphasis. Working with specialist automation consultants, such as Novotek UK and Ireland, helps ensure that an industrial company’s vision is first achievable and then, ultimately, achieved.

The fourth industrial revolution and the IIoT are industry-changing concepts, but they shouldn’t change a company’s focus. If you treat them as new opportunities to achieve core business objectives, then you’ll find that they’re more tech-enabled than tech-driven.
