This year, we  received high attention on our Functional Safety over EtherCAT (FSoE) Solution.

The importance of functional safety are the same throughout the world. It protects employees and equipment, eliminate unexpected downtime, thereby effectively improving the overall equipment efficiency and the manufacturing capacity.

FSoE, which further enhanced the safety of machines, has been the key factor to further increase the production capacity of machineries and factories.

Tips : Industrial Ethernet must not only realize the transmission of data, but also the transmission of the most critical safety control data. EtherCAT uses the Safety over EtherCAT (FSoE) protocol to achieve efficient transmission of safety data, simplify the system, increase flexibility, and reduce the cost of the system.

However, there are two challenges highlighted by our customer when installing FSoE into their safety system.

In short, it is all about how easy and fast they can get into the market.

  1. FSoE Stack can be purchased via stack supplier. However, implementation not only limited to customer’s tuning to adapt their own safety system, but also involves a huge amount of work other than the  FSoE network development, like preparation of certification documents. “This is actually the bothering part for me !”
  2. In case of limitation / challenge during development, customer needs to contact each and every party: stack supplier, device supplier, and might involve IDH or consultant. “This takes too long!”

That’s where Renesas comes in.

As you may know as an  MCU/MPU supplier, Renesas also have SW solutions dedicated for Functional Safety too that are TUV certified.

This FSoE Application SW Kit for RX, together with SIL3 System SW and Self-test SW Kit, enables easier and faster development than conventional process.

Renesas solution


How does Renesas FSoE Application SW Kit helps you?

  1. One stop shop: Renesas supplies SW that includes FSoE slave stack : ETG S (R) v1.2.0 compliant and is IEC61508 SC3/SIL3 certified.  .
  2. Network communication interface SW: Smart API to interface between safety and non-safety I/Os. It also simplifies the interface with Renesas's EtherCAT Slave MCU.

Furthermore,  with the certified Self-test SW and SIL3 System SW, the MCU can do all the safety monitoring diagnosis taski so that you can focus on developing your network application. In addition, the Reference Document onIEC61508 Standard certification guidebook to help you make your certification preparation and process smoother
These total safety package, which only Renesas can offers, makes the whole process much simpler and faster to release to the market.

Before closing this blog, let me share a system example.
Below is the example with RX72M and RX23T, a dual MCU configuration which runs both EtherCAT and FSoE system with our Functional Safety SWs.

Would you want to try it? Yes, free evaluation version of the software is made available to download from Renesas’s website.

By purchasing the Renesas Reference Board, you can try it by setting up and run.

In summary, Renesas FSoE Application SW Kit for RX, along with our SIL3 System SW and Self-test SW Kit will help to solve your challenges much easier and faster.

For those who are now considering developing  safety system, this solution can also be your door opener too.

Today, the functional safety solutions are based on 32-bit high-performance microprocessors RX and RA series MCUs. Depending on market feedback, we will further expand Functional Safety solution toward higher performance device too.
