Industrial IoT (IIoT) is becoming increasingly important for modernizing legacy systems and enabling businesses to remain competitive.

The benefits of using legacy systems in firms can be considerable in some cases. However, outdated systems have potential security, performance, and compliance issues. Modernizing outdated systems with Industrial Internet of Things (IIoT) technology can help reduce exposure to these dangers.

The dawn of Industry 4.0

Once upon a time, the emblem of the Industrial Revolution was the spinning wheels and steam engines of factories. These cogs are still in motion today, and not just in a mechanical sense but also in the digital realm. With the arrival of Industry 4.0, connecting older machines and systems to the cloud is becoming necessary. This process of change is influencing the direction of business as we know it.

IIoT Hardware for legacy system modernization

IIoT hardware is different from traditional IoT hardware. Designed specifically for industrial environments, IIoT hardware enables legacy systems and devices to integrate with modern networks. This makes IIoT hardware more reliable and resilient. It also has more data collection and processing capabilities than traditional IoT hardware. This enables operations such as data collection, remote machine monitoring, and performance reporting. By bringing legacy systems online, IIoT helps manufacturers better understand business performance.

Modernizing legacy systems with IIoT: Challenges and solutions

 Legacy systems can lock up data, greatly hindering automation and operational efficiency. Securing these systems can also be challenging, as many devices may need to communicate with modern networks. 

Legacy systems face a number of challenges, such as the following:

• Security risks: Security flaws are easier to exploit on older systems. This can open the door to hacking and data loss.

• Performance issues: Legacy systems may take longer to do tasks than newer ones. Both manufacturing efficiency and consumer happiness may suffer as a result. 

• Compliance issues: It's possible that older technologies won't meet the standards of today. The company may face fines and other penalties due to this action.

• Prices of IIoT adaptation: We can also add to the challenges associated with IIoT adoption by saying that IIoT solutions are expensive, complex, and difficult to install and maintain.

However, these problems are not insurmountable with proper planning and a good strategy. You can also closely examine operational legacy systems at brownfield manufacturing sites.

Strategies for upgrading: A guided approach to IIoT Integration 

Modernizing legacy systems involves a strategic approach that can be tailored to the unique needs of different industries and companies. Here are some key strategies, along with real-world examples of successful IIoT integration:

Selecting the Right IIoT Hardware

• Strategy: Choose IIoT hardware that aligns with the legacy systems' specific requirements and the business's overall goals.

• Example: General Motors implemented IIoT sensors and devices to monitor equipment health and performance in their manufacturing plants. This allowed for predictive maintenance and reduced downtime.

Determining Appropriate Computing Options

• Strategy: Decide on the best computing option, whether it's cloud, edge, or hybrid, based on the data processing needs and security considerations.

• Example: Siemens used edge computing in their IIoT integration to process data locally in their factories. This provided real-time insights and reduced the need for constant cloud communication. Also, Siemens has increased energy efficiency using IIoT. The company monitors and analyzes energy consumption in its facilities using IIoT sensors. In this way, Siemens could increase its energy efficiency by 20%.

Integrating Security Measures

• Strategy: Implement robust security measures to protect data and devices, considering the vulnerabilities of legacy systems.

• Example: Honeywell's cybersecurity solutions for IIoT ensure that legacy systems in oil and gas industries are protected from potential cyber threats.

Migrating Legacy Systems to the Cloud

• Strategy: Plan and execute a smooth migration of legacy systems to the cloud, ensuring compatibility and minimizing disruption.

• Example: GE Aviation migrated its legacy systems to a cloud-based platform, enabling seamless integration with IIoT devices for enhanced data analytics. GE also improved machine maintenance using IIoT. The company uses IIoT sensors to monitor and analyze the performance of machines. Thanks to this, GE reduced machine breakdowns by 50%.

Replacing Legacy Systems with New IIoT Hardware

• Strategy: Gradually replace or augment legacy systems with new IIoT hardware, following a well-planned roadmap.

• Example: Schneider Electric replaced old machinery with IIoT-enabled devices in their factories, leading to improved energy efficiency and production optimization.

These strategies and examples demonstrate that IIoT integration is not a one-size-fits-all solution. It requires careful planning, selection, and implementation to align with the specific needs and goals of the industry or company. By learning from successful real-world applications, businesses can navigate the complexities of modernizing legacy systems with IIoT and unlock new levels of efficiency, innovation, and growth. All of these processes can be successfully realized with the right planning and strategic thinking.

5 steps to bringing your legacy systems online with IIOT

• Develop a digital transformation map: Determine what the project aims to achieve. 
• Holistically analyze old machines and systems: Understand which equipment can be updated. 
• Choose the right IIoT hardware: Identify the hardware that fits your factory's needs and ensure that the IIoT hardware meets your requirements. Install and configure the IIoT hardware.  
• Choose the best computing option: Decide whether cloud, edge, or hybrid computing is the best fit. 
• Connect IIoT hardware to your legacy systems: Use IIoT hardware to collect data, process it, analyze it, and report on it. 
• Analyze security issues and integrate security measures: Protect your devices and data. Manage IIoT hardware securely and update IoT hardware regularly. 

The road ahead: A vision for the future

 Integrating IIoT hardware in the modernization of legacy systems is a transformational journey that will play a critical role and shape the industry's future. Modernizing legacy systems with IIoT is not just a trend but a necessity in today's rapidly evolving industrial landscape.
