Product Overview - System on Module

Description

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.

Open

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.

Open

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.

Advantages

The SoM - RIN32M3 module offers you a cost effective and easy to integrate communication solution. With just one module you have the for market leading real-time communication systems. The open interfaces allow you to react flexibly in the connector area. RJ45, M12, M8 or MiniIO - no problem. An extensive tool offer for management and integration makes the design very efficient. With the integrated update service, you are always up to date.

SPI operation

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.
