Renesas Electronics Announces Availability of Reference Design Solution for Industrial Remote I/O Devices

As part of its lineup expansion of platform solutions for the R-IN32M3 Series of industrial Ethernet communication system-on-chips (SoCs), Renesas Electronics, a premier supplier of advanced semiconductor solutions, announced the availability of its new Remote I/O Trial Kit—a complete hardware and software reference solution for development of Remote I/O devices typically used for I/O monitoring, communication and industrial process control. The new solution supports the EtherCAT(R) protocol and is now available.

The Remote I/O Trial Kit solution will be available for limited supply to qualified system designers (Note 1) as a reference design that consists not only of an actual remote I/O module but also software, documentation, and circuit schematics. By providing this shrink-wrapped solution that has already completed all the development processes required, system designers will be able to significantly reduce the time from development to evaluation and the approval testing phase and they will profit from lower development risk and costs.

Renesas aims not only to strengthen its support for other communication standard protocols (Note 2) through collaboration with partner companies but will also continue to expand its lineup of application-oriented solutions that further contribute to reliable, fast, and timely product development of end products by system designers.

Key features of the new reference design solution:

• (1) Dramatic reduction in development time

The new reference design solution has been developed based on an optimized system configuration to help the designers reduce BOM (bill of materials) costs of the overall system and eliminate concerns for safety standards, as well as certification procedures from industrial Ethernet communication protocol organizations. This allows the number of process steps, from the start of development to certification procedures, to be reduced by approximately 60 percent or more (Renesas estimate).

• (2) Facilitates development of remote I/O equipment that supports multiple protocols in the same hardware structure

Since the R-IN32M3 Series of SoCs used in this trial kit support protocols including EtherCAT, CC-Link IE (Note 3), Ethernet/IP, and PROFINET, it is easy for designers to develop remote I/O products that support multiple protocols in the same hardware structure.

The optimized printed circuit board in the trial kit is based on the R-IN32M3-EC device, which features integrated memory and two Ethernet PHYs. This helps to develop a more compact system at lower cost.
About the Remote I/O Trial Kit:

(1) Items provided in the Remote I/O Trial Kit

Remote I/O module
          Remote I/O application processing
          EtherCAT communication processing
          ESI file for EtherCAT communication
          Documentation (application note)
          Circuit diagrams (OrCAD data, layout PDF)

The hardware information includes a power supply system structure and component values optimized for the R-IN32M3 specifications and information that both takes into account safety standards and optimized BOM costs. This can be used in end products without modification.

The software includes not only the data processing used in remote I/O equipment, but also industrial Ethernet communication processing as well. This makes it possible to quickly verify Ethernet communication operation.

The remote I/O module, software, and circuit diagram data are provided without charge on a temporary loan basis.

(Note 2)
Renesas’ EtherCAT protocol stack will be available beginning in September 2014. Renesas plans to release other protocol stacks as they are developed. (Availability is subject to change with geographic location.)

(Note 3)
CC-Link IE is supported by the R-IN32M3-CL version. Please note that this module is assembled with the R-IN32M3-EC version.
