Starkly stated sustainability targets such as ‘Net-Zero by 2030’ imply an inherent struggle, and while this may be true in certain arenas, there is a genuine opportunity to achieve environmental goals, automate accountability and improve profitability within manufacturing – all at once.

In this article, we’ll outline exactly how the right capabilities, infused with expertise, can offer a profitable and intelligent pathway to a brighter business and environmental future. Carbon is cash, and reducing your output means retaining capital and growing profitability for the future.

So how is this achieved? Firstly, by fostering a different mindset when conceptualising sustainability measures. Data on utility usage can tell you when you’ve used more or less, but this aggregated data doesn’t have the granularity to explain why. While this is fine for quantifying and reporting on consumption to participate in a carbon exchange, this approach offers no mechanisms to improve these figures. But it doesn’t have to be this way.

In decades past, manufacturers in various sectors have embraced initiatives focused on continuous improvement, aiming to enhance production yields, improve equipment reliability, and minimise waste in materials, labour, and capital. Advanced measurement systems that track metrics like machine downtime and material usage, leading to the establishment of comprehensive factory data infrastructures, all support manufacturers’ end goals.

These systems contextualise raw data by associating it with specific details such as order numbers and product codes. Advanced platforms like Proficy Plant Applications from GE Vernova can integrate data from primary sources like water flow meters into this contextual framework. This practice of collecting detailed data related to core equipment and products results in a robust dataset, which serves multiple purposes:

1. Automating Environmental and Compliance Reporting: Using directly measured consumption data to create regulatory reports and calculate incentives.
2. Enhancing Carbon Accounting: With varying standards for translating energy consumption into emissions, having granular data allows for flexibility in reporting and adapting to evolving auditing requirements.
3. Incorporating Footprint Analysis in Continuous Improvement: Analysing measured environmental factors alongside traditional performance metrics reveals the interplay between operational changes and environmental impact. Comparing a product’s footprint data across different times or locations helps identify significant variations.

This approach allowed a major North American brewer to spot cases where energy consumption varied when all other factors were equal. Measuring energy consumption next to production orders meant it could hunt for root causes through its efficiency management system.

Root causes for relative spikes in usage ranged from inefficient process control algorithms for heating or chilling equipment, inconsistent adherence to recipe setpoints, and poor power management relative to down or idle times. The brewer utilised this insight to make recipes and procedures consistent across all sites.

The result? The brewer met a 5-year energy-savings target in just three years!

Operator Behaviour, Transparency and Compliance

As more firms conclude that a functional information strategy is a critical first step in their sustainability journey, gaining the correct capabilities to gather and process data is essential. In times gone by, multiple data collection regimens assembled reports for different purposes, such as customers or regulators, which led to inconsistencies and undue workload on operators and analysts.

The alternative is a single data platform that serves multiple stakeholders, such as GE Vernova’s Plant Applications. Through a single platform, data is gathered once at an appropriate resolution, and the same data can then be repacked for multiple purposes.

Through this method, operations can automate the management and delivery of regulatory data. Adherence to future carbon passport schemes also becomes a process through which you already have the tools to deal with.

Turning to transparency, increasingly, customers are willing to pay a premium for ‘green’ products, where you can demonstrate a complete genealogy and the positive credentials of your products in total confidence. With a comprehensive data platform in place, you have the power to track and demonstrate the exact journey a product has gone through, from raw materials to finished goods. And that is not to overlook the power of transparent data on your operation.

With greater process visibility, automated with real-time data collection, operations gain the insight required for intelligence decision-making from the shop floor to the top floor. Ingesting and utilising this data with a powerful analytics platform drives an understanding of the cause-and-effect relationships between asset performance and input consumption. This granular data is then fed into corporate EHS and carbon accounting systems, allowing true utility cost profiles to be a part of production costing and planning exercises. Manufacturers then use cross-plant metrics to accelerate best-practice identification and dissemination.

But that’s not where it ends; by embedding analytics into control and visualisation programs, operators can be presented with rich information to drive decision-making at the shopfloor level. By using intelligent systems in this way, operations can also ensure they are not held hostage to the availability of specialists.

Innovative Strategies in Sustainability

To demonstrate how adopting a manufacturing execution system can offer a ‘many birds for one stone’ solution, we can look at the capabilities and conditions of an operation both before and after implementation.

Before

Without a detailed understanding of how changing utility inputs will affect processes, efforts to be ‘green’ can cause efficiency and material losses while also potentially introducing quality or product safety risks.

The differences between equipment and processes also present difficulties in formulating an effective strategy. With better data collection, all elements of variability can be profiled – including materials used in processes.

After

Data-driven decision-making brings cost, quality and carbon footprint into balance. With the confidence to act backed by information, tuning processes and utility infrastructure ensures sustainability efforts do not compromise operational performance.

The root causes of overconsumption are more easily understood, and strategies to mitigate them can be formulated and actioned at pace.

The ‘Many Birds’ at a Glance

If we’ve demonstrated anything in this article, we hope it’s the broad scope of what’s possible when looking to drive sustainability – and reap the real rewards on offer for manufacturing! Here are the key takeaways of what’s on the table as we progress towards environmental goals:

1. Expose hidden relationships between production and sustainability factors.
   • A single MES solution provides insight into materials, recipes, assets and processes to find the root causes of the overconsumption of utilities.
2. Gain a single source of truth and improve the visibility of your consumption.
   • Granular data gathered by the single platform can be packaged, analysed and presented to serve many needs.
3. Integrate metrics and analysis to provide additional insight.
   • Automating analytics within a single, scalable platform provides value from the shop floor to the top floor and drives fast, accurate decision-making powered by information.
4. Automate regulatory compliance and power transparency and traceability.
   • Gain competitive capabilities to demonstrate green credentials to customers and other stakeholders.

Last but not least, and in a nutshell, why select Plant Applications from GE Vernova?

• Flexibility in Data Management: The platform can easily link basic time-series data from meters to a wider range of elements like materials, products, and events, all through straightforward configuration.
• Support for Multiple Stakeholders: Plant Applications offers a variety of reporting and analytics capabilities, catering to both internal stakeholders focused on improvement and external stakeholders, ensuring their diverse needs are met.
• Open and Layered Approach: Unlike many sustainability metrics systems that are manual or limited to specific sensors, Plant Applications enhances existing sensor, automation, and software investments, offering a more integrated solution.

A vital convergence

Cybersecurity is a crucial concern. OT equipment has become more IT aligned by necessity through standard protocols and ethernet/IP connectivity. Like a bucket of cold water, this fact woke the IT world to the significant vulnerabilities presented by connected operational systems. Furthermore, the press has continued to fill with stories of backdoors exploited by nefarious actors and the dire consequences of which to reputations, service, and profitability.

It was time for OT to be taken seriously and become part of the IT estate with the same high standards and best practice approaches to security.

So, what does this mean for you as a manufacturer?

Firstly, you must ensure that your control systems, such as PLC, SCADA etc., are secure from threats by keeping systems up to date and only providing connectivity between systems that require it. Leaving your entire operation wide open, with everything connected to everything else, is particularly hazardous. The optimal solution is to establish communication channels secured via switches and routers, allowing protocols to be enabled and disabled as required. Through this method, you can install firewalls between departments to further mitigate the threat of a cybersecurity breach.

The second point to consider is access control. Users should only be granted permissions to systems they require within an IT-supported domain. Paired with appropriate password complexity, a policy of regularly changing those passwords can minimise a potential vector of attack.

Next is virtualisation. By abstracting OT systems from the IT hardware, you can install physical hosts in an environmentally controlled data centre; rather than the old method of putting server racks under desks in control rooms, where they were subject to dust, heat, and the occasional accidental kicking from a steel-toe-capped boot.

Rounding out this brief overview is patching and backups. Patching regularly, at the same frequency as IT systems, ensures systems are constantly kept up to date and reduces the impact of ‘timely’ vulnerabilities such as Log4j. We still visit sites where Windows XP, NT and Server 2000 are still in use. These operating systems are running long after official support has ended, meaning security patches are no longer available and the vulnerabilities are well known and widely published.

Because OT should now be firmly on your IT department’s radar, creating a thorough backup regime will mean your systems are recoverable in the event of data loss due to a ransomware attack, operator error or any other disruption.

Food production is truly a sector that operates under the mantra of “reinvent the everyday, every day”. The sector is constantly evolving, whether manufacturers are innovating new product ranges that meet changing consumer tastes or switching packaging materials to extend shelf-life or reduce waste. And these are just examples of substantial shifts; food manufacturers are also regularly making smaller challenges by refining recipes, adapting processes or adjusting ingredient and material supply lines.

Despite — or perhaps because of — the environment of constant change, food processors can benefit more than many other manufacturers from carefully targeted use of data collection, visualisation and analysis solutions. After all, yesterday’s optimisation isn’t particularly optimal if today means a new stock-keeping unit (SKU), a new critical ingredient supplier or a new recipe.

The approach that many businesses take to becoming data-driven is to extensively map out their digitalisation journey, with each aspect comprehensively planned. This doesn’t generally support the flexibility needed in food manufacturing.

Rather than taking this approach, modern solutions make it possible to build or buy micro-applications that share common data infrastructure and even app-building or visualisation tools. This means that impactful new capabilities can be adopted through fast initial works that create re-usable building blocks. Later works then become incremental, rather than potentially having different systems creating overlapping capabilities.

Micro-apps in practice

We can see how this micro-app approach can be put into action by considering one of the most common challenges in food processing: managing the effect of variability in key ingredients, so that yields are maximised with minimal re-work or ingredient waste. It’s likely that a manufacturer would already have some of the information needed to address the challenge. The question is, how can you quickly supplement what’s in place?

It’s a safe bet that the factory has automation and maybe supervisory control and data acquisition (SCADA) systems, so there is an abundance of machine-generated data to tell us about the details of how processes are performing. Focussing more closely on yield performance, we can assume our manufacturer has a lab system where in-process and finished good tests give very clear indicators of how well a product is being made.

From Novotek’s experience, the most common gaps in tackling yield issues come from two areas. The first is supplier quality data, which is often provided either written down or in an electronic format that doesn’t mesh with existing systems. This makes analysis more difficult, because there’s no actual database to work from.

The second area is that the variations in raw materials that affect yields may actually be within the specifications defined for those materials. As such, there may not be an obvious fix. It’s likelier that material data needs to be analysed alongside several process performance and quality performance data points. Understanding the relationships between more than two or three variables will probably mean adding a new kind of analysis tool.

Micro-apps can be highly focussed on the core capabilities required. In this case, the micro-app would provide three core functions. First, it would provide a simple means to capture ingredient quality data as it’s received, into a system that also holds the specific material characteristic specifications and limits – all on a “by-lot” basis. It would also offer a machine learning tool that can help clarify how the range of material quality variation can be managed in relation to what machine settings or recipe adjustments might allow for good final yield and quality results.

Finally, the micro-app would be able to alert production staff to make recommended changes to a recipe or process as different raw material lots are staged for use – an automated monitor of yield/quality risk from material variation. This could be as simple as a new smart alarm sent back to existing SCADA, or a notification on a smartphone.

Industrial software vendors are adapting their offers, in recognition of the trend towards micro-apps aimed at specific business processes. So, the software licensing needed to enable material data collection and quality specification monitoring on a key process would be built around a low user count and narrow set of underlying configuration and integration points, rather than a comprehensive plant-wide project. That can mean starting investments in the low thousands for software and some deployment work.

Some of Novotek’s customers are now progressing through projects defined by such very specific functional needs. Our job at Novotek is to ensure that any new solutions serve the purpose of being able to act as supplements to other such micro-apps in the future.

Next stages

A strategic advantage of micro-apps is that the planning and execution stages are less time-intensive than a far-reaching, plant-wide digitalisation project. Food engineers can do several things to begin reinventing their everyday processes. For example, food manufacturers can deploy predictive downtime applications on key processes. These are apps that can even take into consideration whether the products made have their own impact on failure modes.

Each micro-app reflects an opportunity to make the overall food manufacturing operation more adaptable. This means that innovation in products, processes and business models can be done, all the while knowing that refining and optimising the “new” won’t be held up by tools and practices that are too difficult to adapt from the “old”.

The best approach may be to let the data dictate where to focus your innovation efforts. Or, if there’s a lack of useful data, then that itself may be the answer.

In this whitepaper, Novotek UK and Ireland explains how utilities operators can get to grips with data management to create an effective data-driven approach to innovation. Covering how to consolidate and modernise assets for data collection, how to make sense of utilities data and which method to use to get the most long-term value from data, the whitepaper is an invaluable resource for utilities operations managers and engineers.

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.
