"The combination of the R-IN Engine and CC-Link IE is
ideal for utilizing IoT / M2M"
Renesas Electronics provides 1 Gbps-compliant industrial Ethernet communication LSI
While IoT / M2M, which allows autonomous control of devices, enables production efficiency in manufacturing, it also causes concern over bloated communication traffic. To deal with this issue, Renesas Electronics developed a solution based on both "performance enhancement of devices" and "broadband support". Akira Denda of Renesas Electronics states that a new engine for the former and CC-Link IE compliance for the latter can resolve this issue.
"Among the various contexts of IoT / M2M, nothing produces larger volumes of data than manufacturing facilities. This is because sensors arranged throughout the production line continue to collect data. While a vast amount of data enables more detailed analysis, it constitutes a large load on the processing infrastructure. The increased load on the network promotes delay and decrease in data quality, and increases the power consumption of the PLC that controls devices.
Given this background, we released the industrial Ethernet communication LSI "R-IN32M3 Series" in 2013. The main feature of R-IN32M3 Series is the "R-IN Engine" which turns a part of the real-time OS function into hardware in pursuit of high-speed performance. By reducing the load to the CPU, a speed increase of 5 - 10 times the conventional speed has been achieved.
Resources vacated by the speed increase can be allotted to the device's primary processing of data. Since it uploads only the valid data after performing statistical processing of data and detection of bad data, rather than simply uploading all the raw data, the network bandwidth can be effectively utilized.
In keeping with the increased attention being paid to IoT / M2M, we have decided to ship the new LSI "R-IN32M4-CL2" in October 2015. Like the R-IN32M3 Series, it is equipped with the R-IN Engine, as well as having the new 1 Gbps PHY built in.
In the past, industrial Ethernet with 100 Mbps was thought to be sufficient. However, considering the growth of the environment in which IoT / M2M connect all devices, 100 Mbps will eventually be insufficient. In addition to the R-IN Engine implemented to suppress the amount of communication data, we have also taken an approach to implementing broadband for the network itself.
Although R-IN32M4-CL2 is compliant with the same protocols as the R-IN32M3 Series, it is not an exaggeration to say that it is essentially intended for CC-Link IE. This is because the only industrial Ethernet that supports 1 Gbps broadband at the moment is CC-Link IE. To accommodate the development of IoT / M2M, we felt it necessary to actively support the broadband CC-Link IE.
We have organized the "R-IN Consortium" to support the development of products using the R-IN Engine, promoting collaboration among vendors. We are confident that R-IN32M4-CL2, which allows CC-Link IE to realize its features to the fullest, will be the core of the collaboration."
