Based on a RIN32M3EC CPU in combination with GOAL technology from PORT, this SoM offers PROFINET, EtherNetIP, EtherCAT and CANopen on board. Simply connect via the SPI of your host controller - and your applications are already multi-protocol capable.start enquiry
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.
The SoM module has been designed for use in industrial applications
The SPI of the SoM-RIN32M3 module is intended to interface the module to the external application processor. Because of the independency between the module clock and the clock of the external application processor the serial transfer with the SPI interface is executed in asynchronous mode by the following 3 module pins:
MOSI (master out, slave in)
MISO (master in, slave out)
SCLK (RSPI clock) signals
SS (slave select)
The application controller as SPI master determines the SPI communication mode. The SPI data format can be switched between MSB first and LSB first. The number of bits in each transfer can be changed to any number of bits from 8 to 16, or to 20, 24, or 32 bits. Communication bases on a 128-byte transfer buffer, which can transport multiple requests.
Communication is based on a cyclic scheme, where process data can be transmitted cyclically with each request of the application controller. Non-Realtime communication (RPC) uses the same transport, however processing is decoupled from the Realtime ommunication. Thus, real time data can be exchanged independently from function calls of the API.
For comfortable and easy configuration and object dictionary management, port provides its Unified Design Tool Platform which enables the user to develop communication solutions using port stacks rapidly.
The individual functionality for each stack is realized by plug-ins for each protocol. So the user has only to learn how to work with one tool.
The PROFINET / EtherNetIP Design Tool contains the unified Design Tool platform as well as the plug-in for port’s PROFINET IO & EtherNetIP stack.
