The manufacturing sector is undergoing a dramatic transformation that has been dubbed the fourth industrial revolution. The first industrial revolution involved the adoption of external power generation using windmills and water wheels, the second industrial revolution included the use of motors in machinery and the electrification of factories, and the third industrial revolution incorporated control automation for the machinery in factories. The fourth wave is a data-driven revolution where data and operations play a significant role in developing and sustaining a competitive, scalable, and innovative facility. For achieving the benefits of Industry 4.0, having a good amount of usable data is important, but what you do with it gives you the edge to stay ahead.
In 2020, during the onset of the pandemic, many traditional industrial sectors like oil and gas, power and utilities, and manufacturing began adopting digital tools to transform, address vulnerabilities and digitize. However, in many of these industries, data was inaccessible and disconnected, and finding usable data was a bigger roadblock than building solutions. To resolve this issue, we need a new hassle-free solution that enables industries to aggregate, standardize and contextualize industrial data from sensors, controls, etc. for business users across the organization. This is exactly what DataOps has to offer.
The term DataOps can be defined as a framework that addresses issues with data architecture and integration and offers data standards and contextualization for use across the organization. In order to securely deliver reliable, intelligible, and ready-to-use data across the organization, DataOps orchestrates people, processes, and technology in a repeatable and scalable manner. In an industrial setup, DataOps enables collaboration among data stakeholders across the organization.

Prior to Industry 4.0, industrial data architecture had evolved over the years into a complicated layered approach defined in the Purdue Model or ISA-95. In this model, data flew from sensors to automation controllers to supervisory control and data acquisition (SCADA) or human-machine interfaces (HMI) to manufacturing execution systems (MESs) and finally to enterprise resource planning (ERP). The data volume drastically decreased on moving up the stack. At each point of connection between levels, communication protocols tended to be proprietary and one-of-a-kind rather than reusable ones. Additionally, data integrity was so poor that many businesses updated their MES and ERP systems manually and did not even link them to their manufacturing equipment.

For many years, processing data through multiple layers of systems worked, mostly because the volume of data was manageable. The amount of data being moved up the stack was limited and most of the data used by the system were generated in the previous system. However now, the situation has changed drastically. Pushing excess unused data through systems that do not need it will complicate and slows down data processing capabilities and compromise data security. This is where Industry 4.0 comes to the rescue. Today, data is required close to the equipment, in local data centers, and occasionally in cloud-based systems. A new class of software solutions is emerging to address these issues with data architecture and the need for data contextualization and standardization. These software solutions might hold the key to encouraging businesses to adopt Industry 4.0. When created exclusively for Industrial data, this category is known as Industrial DataOps, or just DataOps.
By now, we have established what Industrial DataOps means, but we still have to define the capabilities of DataOps in order to achieve value. An Industrial DataOps platform should have five essential functionalities:
From a manufacturing perspective, motors, valves, conveyors, machinery, and other similar pieces of equipment produce industrial data. A factory may have hundreds of PLCs and machine controllers, many of which were likely acquired from various suppliers at various points in time. The data points available on the controllers vary from one controller to the next, and very few organizations can enforce any consistency. The data available is still disconnected and inaccessible for a large number of industrial organizations.
Finding usable data is a time-consuming task that often becomes a bottleneck. To be used effectively and yield useful insights, data needs context to be examined across machinery, processes, and products. The data points on industrial machinery were designed for the efficiency of communications and use by industrial software solutions and generally do not include any contextualization, standardization, or documentation of the data packets. This “contextualization” is often stored in an MES, asset management system, or other database system—or may just be known by the operations technology (OT) team. The context must be efficiently merged with real-time data to make the data usable.
To manage the data volume generated across multiple devices and controllers, correlate the data, and provide it to the consuming apps, the DataOps solution needs a set of standard models which correlate the data by machinery, process, and products and present it to the consuming applications.
Information technology (IT) systems and industrial devices and systems have different communication protocols. Despite growing support for OPC UA and other open protocols, industrial devices, and systems still frequently employ proprietary protocols. With the widespread use of APIs and custom integrations, IT systems communicate using their own protocols. IT systems have started using MQTT to communicate with edge devices. In order to reduce cybersecurity exposure and protect encrypted communications with low overhead, MQTT offers a highly flexible pub/sub approach. With the addition of the Sparkplug specification, MQTT has been enhanced to be more practical in industrial settings and to facilitate integrations.
On the IT side, numerous systems are connected directly with databases and through RESTful APIs. Using industry standards and adding value to business applications that follow current IT best practices, an industrial DataOps solution must be able to interact smoothly with devices and data sources at the OT layer.
Information flows must be controlled and managed through a system that allows for their identification, activation, deactivation, and modification. Machine modifications must appropriately reflect in the data collected and translated in order to ensure that usable data is being stored. Knowing what data is being transferred from one system to another and having the ability to stop it to avoid vulnerabilities are crucial from a security standpoint. Nowadays, a lot of external vendors seek machine data to offer improved service. The team in charge of running the machine will need to have control over the data flowing and the frequency or set of circumstances under which it does so. Additionally, the operations team will need the ability to stop the data flow if the vendor no longer requires it. Consequently, controlling the information flow is a crucial part of any industrial DataOps solution.
Industrial data differs from the conventional transactional data kept in most IT systems in terms of its immense volume and scope. Industrial data is generated by thousands of different devices and in order to meet the objectives of analytics or visualization, this data must be gathered, contextualized, and delivered at a resolution that is specific to each use case. Industrial data is often used within milliseconds to seconds post creation. As a result, extract, transform, and load (ETL) batch processing methods designed for transactional data do not perform well for industrial data. Before being kept, industrial data needs to be vetted or contextualized close to the machinery. The intellectual understanding of a manufacturing plant is frequently stored in industrial data.
Industrial equipment comes in many shapes and sizes and runs in many different environments. The processing of the data might take place in the cloud, on-premise data centres, or close to the machinery, depending on the analytical or visualization application. The industrial DataOps solution must be running close to the device and feed the specified frequency or conditions of data to the applications. To enable data normalization and standardization, the system must also allow for model sharing throughout the organization.
So far it can be concluded that for a manufacturer, an effective DataOps practise might mean the difference between capturing a growing market and holding excess inventory as a result of unintentionally entering the market at the other end of a trend. Manufacturers can leverage it to remain on top of shifting consumer needs, supply chain and logistics information that could have a significant influence on the business, and anything else that uses data fast and accurately. But we still have one big problem- how do organizations handle the large volumes of disorganized manufacturing data in a manner such that it becomes usable?
We have discussed how DataOps is the key to an industrial transformation, we have defined DataOps and the essential components of a DataOps platform, but we still need to define how to handle data and make it available for processing. We are all aware of the large volumes of data being generated every day from manufacturing processes that are highly disconnected and practically unusable and that data stays fundamentally meaningless and of no economic use unless it can be converted into valuable insights.
That’s where the Four C’s enter the picture.
The Four C's stand for how businesses manage data and make it accessible for analytics processing which can then be used to derive valuable insights for the organization. The Four C’s of the Industrial DataOps methodology, according to the Manufacturing Leadership Council are:
Connected Data: This is where data mingles and silos collapse. This makes it possible to conduct in-depth and complicated analysis that would not otherwise be possible. IIoT, cloud, and edge technologies utilize connected data. It is widely accepted that data kinetics enables value maximization, which means that decisions about where to store data should be based on where it can be best accessible and curated rather than on the lowest cost.
Curated Data: Curated data refers to the moment the data gets combined into a usable form. As massive amounts of structured and unstructured data continue to get stored in data lakes, unattended data flows to create an environment that is quite similar to a data swamp, making it challenging to identify the relevant data. To ensure the results are as accurate as possible, data engineers simply gather relevant data and clean it up for analysis. They take massive data sets and filter them to the data that is required for a particular scenario. It is important to note that curation is a data engineering activity that includes a lot of sub-activities like data extraction, data cleaning, normalization, and data standardization
Contextualized Data: This indicates that the data has added layers of information and an industry expert is required to give the data more context. In order to derive actionable value from data, organizations must develop the ability to handle both structured and unstructured data, with a focus on contextualizing data depending on specific operational circumstances. The data qualifiers that are included will enhance the meaning of the original data, adding another layer of value beyond simply blending and curating the data that is received. By combining data in novel ways that reveal fresh light on a business or operations issue, contextualization enables the company to be more agile. As with other areas of digital transformation, expanding this maturity across the organization and addressing data quality issues will require new skills and prioritization, understanding business scenarios, and developing automated/ML approaches to help apply context at scale.
Cyber-Confidential: This refers to the requirement for cybersecurity to scale along with increasing connection and customization levels of data initiatives. The possibility of mass customization is one of Industry 4.0's most exciting promises. Combining data from numerous sources, including data from customers among many others, is necessary to fulfill that promise. The importance of safeguarding and securing data will increase since businesses will be dependent on incorporating data from customers into production. Customer data must be protected at all costs, but this can add more complexity for specialists in data governance and security and can raise concerns about data privacy. As more and more connected devices are incorporated into our existing manufacturing process, the threat surface increases exponentially. Every product, sensor, and edge device can be a vulnerability that must be safeguarded. This indicates that resource allocation to cybersecurity, data privacy, and compliance issues will need to keep pace with the digital transformation of the manufacturing industry. Increasing vulnerability and threats like advanced malware, worms and advanced persistent threats coupled with GDPR compliance issues will require training the new workforce to specialize in the field of data security.
An agile DataOps platform that captures, organizes, structures, stores and performs analysis of data can go a long way in unlocking the full potential of Industry 4.0. From data sources to consumers, an industrial DataOps platform can handle data at every stage of the production process and convert data into insights that can be used to make business decisions.
