PLCs ensuring OT security

Process controls engineers should take note of the recent advancements in OT security as Mitsubishi and Nozomi Networks introduce ARC embedded system processors into the PLC landscape. This integration, featured in the MELSEC IQ-R family of PLCs, enables security at the chip level, aligning with Industry 4.0 trends and IoT proliferation.

By embedding real-time AI-based protection and enhanced device visibility, Control Design wrote, Nozomi Networks’ technology helps identify and respond to unauthorized access or network anomalies, a significant improvement in maintaining the health and integrity of industrial automation environments.

Engineers working in sectors with critical processes—such as nuclear, pharmaceutical or high-speed manufacturing—could greatly benefit from these enhancements, offering more robust traceability and anomaly detection capabilities. Control’s partner publication, Control Design, delves deeper into this topic in this article.
