The Internet of Things (IoT) has been around for over a decade, but its full potential is still far from being realized. While there have been notable advancements—such as wearable devices, smart sensors, and smartphones—users haven’t fully experienced the transformative benefits that connected systems can offer. Technologies like cloud computing, big data, and artificial intelligence are pushing the IoT forward, yet they also introduce new challenges. Today, the main barriers to widespread IoT adoption include cybersecurity threats, privacy concerns, and economic factors such as cost and return on investment. PICMG’s standards-based solutions are playing a key role in accelerating the deployment of Industrial IoT (IIoT), making it easier for industries to implement reliable and scalable systems.
This doesn’t mean the future of IoT is uncertain. On the contrary, current applications are well-suited for today's needs, and many of the obstacles mentioned are not as critical now as they might become in the future. This is especially true for the industrial markets served by PICMG, including military, medical, transportation, and automation sectors. These industries have long relied on embedded computing and control solutions, and PICMG technology is already used across land, air, and sea, controlling everything from military equipment to smart factories and scientific instruments.
PICMG is actively working to bring IIoT into reality by developing open computing specifications and design guidelines that enable companies to build interoperable, high-quality solutions. Leveraging its expertise in industrial computing, PICMG is expanding into the IoT space and collaborating with other industry organizations to create a more unified ecosystem.
**Industrial IoT Unique Features**
Compared to traditional industrial automation, IIoT has three defining characteristics: pervasive perception, advanced data analysis, and IT methodology.
**Pervasive Perception**
Unlike traditional automation, which relies on sensors at key control points, IIoT uses a wide array of interconnected sensors and actuators throughout the system. These devices monitor everything from machine health to environmental conditions, enabling real-time insights that drive better decision-making. Pervasive perception is the foundation of IIoT, allowing for deeper data collection and more accurate predictions.
**Advanced Data Analysis**
By collecting and analyzing sensor data, IIoT systems can significantly improve operational efficiency. Smart factories, for example, use this data to increase equipment uptime, reduce costs, and optimize resource use. This level of insight is a major driver behind the rapid growth of IIoT.
**IT Methodology**
The integration of information technology into industrial systems brings several advantages. It allows access to a broader talent pool, promotes standardization, and enables companies to leverage existing IT infrastructure. This approach makes IIoT more scalable, flexible, and cost-effective.
**Obstacles to IIoT Applications**
Despite its promise, IIoT faces several challenges. According to the 2017 Automation World survey, the top three hurdles are network security, lack of standards, and the presence of legacy systems.
**Cybersecurity**
With billions of connected devices, securing IIoT systems is a critical concern. Vulnerabilities in smart factories, power grids, or transportation networks could lead to serious safety risks. Most IIoT deployments require private, secure networks to protect against cyber threats.
**Lack of Standards**
Many industrial systems rely on proprietary solutions, creating isolated "information silos." Open standards like CompactPCI help bridge these gaps, but more work is needed to ensure seamless integration between different devices and platforms.
**Legacy Systems**
Older equipment often coexists with new technologies, requiring backward compatibility and interoperability. PICMG addresses this by ensuring its solutions support both legacy and modern systems.
**IIoT Architecture Overview**
Smart factories represent one of the fastest-growing segments of the IIoT market. These facilities integrate robotics, automated testing, and real-time monitoring to boost productivity and quality. All devices are connected through Ethernet or Industrial Ethernet, allowing centralized control and data analysis.
In a smart factory, everything from inventory systems to environmental controls is monitored and optimized. Sensors gather data on machine performance, energy usage, and more, feeding into a central control system that visualizes and manages operations.
**Smart Factory Case**
A typical smart factory includes multiple robot lines, test equipment, and process tools, all integrated with standardized interfaces and data models. Real-time monitoring ensures optimal production levels and quality. Inventory systems and environmental controls are also managed through IIoT, enabling smarter purchasing and resource allocation.
At the bottom of the IIoT architecture, sensors and controllers collect physical data, which is then processed and analyzed. These systems are designed to be robust, capable of operating in demanding industrial environments.
Traditional equipment can be upgraded gradually, with PLCs serving as intermediaries before full IIoT integration. The ultimate goal is a converged network gateway that unifies all data sources, enabling efficient and scalable IIoT operations.
**PICMG’s Contribution to IIoT**
As IIoT continues to evolve, standardization becomes increasingly important. PICMG, with its long history in industrial computing, is helping shape the future of IIoT through specifications like COM Express and CompactPCI Serial. These proven technologies provide a solid foundation for IIoT gateways and controllers.
By promoting open standards, PICMG is making it easier and faster for companies to adopt IIoT. Its solutions enhance interoperability, reduce complexity, and support the long-term scalability of industrial systems.
