With the advancement of Industry 4.0 and the Industrial Internet of Things (IIoT), the various systems (things) need to connect to and communicate with each other. As a result, the use of Ethernet-based networks in factories is becoming more widespread, as deterministic, safe communications across all levels of the factory are more critical than ever.

To meet these trends, Renesas is working on realizing the OPC Unified Architecture (OPC UA) on various Renesas MCU/MPU/ASSP. OPC UA is a machine-to-machine communication protocol for industrial automation developed by the OPC Foundation. Renesas already has various communication technologies for industrial ethernet, industrial fieldbus, sensorbus, and more. By adding OPC UA, Renesas will continue to contribute to a smart society via a secure, real-time, end-to-end gateway solution.
