R-IN32M3 Industrial Ethernet Module

Certified Multiprotocol Industrial Ethernet Solution for PROFINET® and EtherNet/IP™

The Renesas R-IN32M3 Industrial Ethernet Module is a certified hardware and software solution that speeds up product development and brings it to the market quickly. Based on Renesas technology and quality standards, the module includes certified software of leading Industrial Ethernet protocols PROFINET® and EtherNet/IPTM. Other industrial protocols such as EtherCAT® are under preparation and will be available soon.

The R-IN32M3 Module includes a Renesas microcontroller running a protocol library which supports various kinds of real-time industrial Ethernet communication protocols. A well-documented generic application programming interface (API) allows for simple access to the protocol library by an application processor in order to exchange real-time network data with a user application via a lean SPI module interface.

The generic API is an abstraction platform for real-time communications offering scalable multi-protocol solutions such as PROFINET RT, EtherNet/IP, and EtherCAT. The external application processor has full control of the protocol stacks running on the module’s CPU without interfering with the modules’ real-time communications or wasting the CPU performance of the host processor.

The implementations of the currently available industrial Ethernet protocols, PROFINET RT, EtherNet/IP, and EtherCAT, comply with the latest specification releases. An extensive tool chain, covering an evaluation board (module and application processor), API source code, and host application examples including extensive documentation, eases integration into your target application environment. All this enables users to set up a lean and independent connection to existing or new applications, products, and networks while accelerating times to market.
