One Solution for PROFINET, EtherNet/IP and EtherCAT

STMicrolectronics STM32F meets real-time multi-protocol solutions from port

With the STM32F NUCLEO 144 board in combination with the ARDUINO board "SoM IoT" from port - test all functions - you will be convinced.


With the SoM IoT, port offers a cost-effective and fast solution for integration into PROFINET, EtherNetIP and EtherCAT networks. An extensive toolchain is available to help you with the integration and help you create the object data.


About SoM IoT module

The SoM RIN32M3 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 (Application Programming Interface), the protocol library can be simply accessed from an application processor in order 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.

The currently available industrial Ethernet protocols PROFINET RT, EtherNet/IP, EtherCAT and the common Fieldbus CANopen implementations are complying with the latest specification releases. An extensive tool chain covering evaluation boards (module and application processor), API source code and host application examples including extensive documentation makes the integration into your target application environment quite easy. All this enables the users for a lean and independent connection to existing or new applications, products and networks while accelerating time to market.
