Industrial Ether Connectable IoT Sensor Hub

This design showcases an easy-to-build industrial Ethernet-connectable sensor hub that utilizes Renesas’ MPU, power products, and sensors. The system efficiently collects data from sensors connected to the MPU and transmits it to programmable logic controllers (PLCs) and/or controllers that comply with specific industrial Ethernet protocols.

System Benefits:

• Supports multiple industrial Ethernet protocols, including EtherCAT^®, Ethernet/IP™, PROFINET^®, Modbus TCP, and OPC Unified Architecture (OPC UA), for seamless PLC and controller communication.
• Sensors can be connected via several interfaces, such as CAN, RS-485, and I²C.
• The MPU features dual CPU cores: Arm^® Cortex^®-A7 and Arm Cortex-M3, allowing for the implementation of communication software on the Arm Cortex-M3 core and application software on the Arm Cortex-A7 core separately.
• The MPU includes features that help reduce the BOM and the size of the PCB.
