The Internet of Things (IoT) has been around for over a decade, yet its full potential remains unrealized. While significant progress has been made—such as the rise of wearable devices, smart sensors, and smartphones—users have not yet fully experienced the transformative benefits that connected systems can offer. Cloud computing, big data, and artificial intelligence are now driving IoT forward, but they also introduce new challenges. Today, the main hurdles in IoT commercialization include cybersecurity threats, privacy concerns, and economic trade-offs. PICMG’s standardized solutions play a crucial role in accelerating the deployment of Industrial IoT (IIoT), making it more accessible and efficient.
This doesn’t mean the future of IoT is uncertain. On the contrary, current applications are already demonstrating value, with many of the previously mentioned challenges being manageable or even less impactful. This holds true for industrial markets served by PICMG, such as military, medical, transportation, and automation. Embedded computing and control systems have long been essential in these sectors. Today, PICMG technology operates on land, air, and sea, controlling critical infrastructure like military equipment, transportation systems, and smart factories, supporting scientific and medical instruments with reliability and precision.
PICMG is actively working to bring IIoT closer to reality. By offering open computing specifications and design guidelines, it empowers companies to develop high-quality, interoperable solutions. Leveraging its expertise in industrial computing, PICMG is expanding into the IoT space and collaborating with other standards organizations to shape the future of IIoT.
**Industrial IoT: Unique Features**
Compared to traditional industrial automation, IIoT stands out with three key characteristics: ubiquitous perception, advanced data analysis, and IT methodology.
**Ubiquitous Perception**
Unlike conventional automation, which relies on sensors at critical points, IIoT uses widespread, interconnected sensors and actuators across various operations—from machine health monitoring to environmental tracking. This extensive sensing capability forms the foundation for advanced analytics and real-time decision-making.
**Advanced Data Analysis**
By collecting vast amounts of sensor data, IIoT systems enhance operational efficiency. Smart factories, for example, use this data to improve uptime, optimize asset usage, reduce costs, and boost productivity. These improvements are driving the rapid adoption of IIoT across industries.
**IT Methodology**
The integration of information technology into industrial systems brings numerous benefits. It enables access to a broader talent pool, promotes standardization, and allows IIoT systems to leverage existing IT hardware and software. This convergence of IT and OT (Operational Technology) is a major driver of IIoT growth.
**Obstacles to IIoT Adoption**
Despite its promise, IIoT faces several challenges. According to the 2017 Automation World survey, the top issues are cybersecurity, lack of standards, and the presence of legacy systems.
**Cybersecurity**
With IoT devices controlling critical infrastructure, security is a top priority. A breach in a smart factory or power grid could lead to catastrophic consequences. As a result, most IIoT systems operate on secure, private networks with strict access controls.
**Lack of Standards**
Proprietary systems create information silos, making integration difficult. Open standards, such as those promoted by PICMG, help bridge these gaps and enable seamless communication between devices and platforms.
**Legacy Systems**
Many industrial environments still rely on older equipment. Effective IIoT strategies must accommodate these systems through backward compatibility and interoperability, ensuring smooth transitions without disrupting operations.
**IIoT Architecture Overview**
Smart factories represent one of the fastest-growing segments of the IIoT market. These facilities integrate robots, automated testing equipment, and other smart devices, all connected through standardized networks. Real-time data from sensors ensures optimal performance and quality.
**Smart Factory Case Study**
In a smart factory, every component—from production lines to inventory systems—is monitored and controlled. Environmental factors like lighting and temperature are also tracked to optimize energy use. All this data flows into a central control system, where IT tools visualize and manage operations efficiently.
At the lowest level, sensors and controllers collect and transmit data. These devices are designed to withstand harsh industrial environments. Traditional systems can be upgraded gradually, using gateways to translate old protocols into modern IIoT formats.
The ultimate goal is a converged network that integrates all functions seamlessly. With low data traffic, even basic gateways can support IIoT operations effectively.
**PICMG’s Role in IIoT**
As IIoT depends heavily on industry standards, PICMG’s experience in industrial computing makes it a natural fit. By developing sensor network specifications and leveraging proven technologies like COM Express and CompactPCI Serial, PICMG helps build reliable and scalable IIoT solutions.
Through standardization, PICMG accelerates IIoT adoption, making it easier and faster for companies to implement smart, connected systems.
