Why Are Microcontroller Boards Like Arduino Not Common in Industrial Settings?

Microcontroller boards like Arduino are indeed used in some industrial applications but they are not as prevalent as other solutions for several reasons. This article delves into the specific challenges and requirements that make dedicated industrial controllers more suitable than Arduino boards in many scenarios.

Robustness and Reliability

Industrial environments often demand highly reliable and robust systems. While microcontroller boards like Arduino can be perfectly adequate for prototyping and hobbyist projects, they may fall short in industrial applications due to their lack of stringent reliability and durability standards.

Performance

Arduino boards typically have limited processing power and memory compared to industrial controllers like Programmable Logic Controllers (PLCs). In complex applications that require high-speed data processing or intricate control systems, more powerful solutions are preferred.

Safety Standards

Many industries are subject to strict safety and regulatory standards such as ISO and IEC. Industrial controllers are specifically designed to meet these standards, while Arduino boards do not typically come with the necessary certifications for safety-critical applications.

Real-Time Processing

Some industrial applications require real-time processing capabilities that Arduino boards may not provide effectively. Dedicated industrial controllers are specifically designed to handle time-sensitive tasks reliably.

Scalability and Integration

Industrial applications often need to integrate with existing systems and scale easily. Professional-grade hardware typically offers better options for integration and scalability, including support for industrial communication protocols.

Support and Documentation

Industrial solutions frequently come with extensive documentation, support, and training resources that are crucial for businesses. In contrast, Arduino is largely supported by a community, which may not be sufficient for large-scale industrial implementations.

Cost Considerations

While Arduino boards are inexpensive, the total cost of ownership in an industrial setting includes factors like maintenance, support, and potential downtime. These considerations can make dedicated industrial solutions more economically viable in the long run.

Conclusion

While Arduino boards are excellent for prototyping, education, and hobby projects, their limitations in robustness, performance, safety, and support make them less suitable for many industrial applications. However, they can still be found in specific use cases, particularly in small-scale automation, research, and development environments.

This article highlights the key differences between Arduino boards and industrial controllers, providing insights into why dedicated controllers provide better solutions for demanding industrial applications.
