SoM Provides Real Time Industrial Communication

PORT’s RIN32M3 System on Module (SoM) is based on a RIN32M3EC CPU and the company’s GOAL technology. Providing communications in real time, the SoM offers PROFINET, EtherNetIP, EtherCAT and CANopen on board. It connects via the SPI of a host controller and user applications are automatically multi-protocol capable.


The RIN32M3 module offers a cost effective and easy-to-integrate communication solution. It is a ready to use, pre-certified (with example application) dual port Ethernet module solution currently available for PROFINET RT, EtherNet/IP, EtherCAT and CANopen real-time protocols, including an embedded 2-port Ethernet switch with a 3rd internal port for bus and ring network topologies. In the SoM – RIN32M3 module a Renesas microcontroller is integrated running a protocol library which supports various kinds of real-time industrial Ethernet communication protocols. With a well-documented generic API, the protocol library can be accessed from an application processor to exchange real-time network data with the user application via a lean SPI module interface.

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