Success Story: Product Development based on the netX 90

To develop its first own product, the engineering firm kumkeo GmbH chose the world‘s smallest multiprotocol chip from Hilscher, the netX 90.

The requirements for the desired solution were clear to the customers from the wind energy sector: two rotary encoders of a wind turbine provided their data via a BiSS safety interface, while the higher-level controller expected the measurement data to be provided via PROFINET and PROFIsafe. A reliable and, above all, secure protocol converter had to be developed to convert the data received from the sensors to a signal expected by the controller.

kumkeo developed a series production-ready product, the BiSS Safety 24 Volt > PROFINET/PROFIsafe protocol converter in a record time of just nine months. The protocol converter supplies two BiSS safety sensors with 24 volts and reliably reads out their values. The data obtained as a result, based on the netX 90, is made available to the safety controller via PROFINET/ PROFIsafe.

One further hallmark of the netX 90 SoC is its multi-protocol capability. This flexibility enables the engineering firm to develop further customized versions of the protocol converter as well as other products within a short space of time.

We were able to put our first protocol converter into series production in a record time of just nine months based on the netX 90 as a certified product. The multi-protocol capability of the netX 90 allows further products and variants of the converter to be developed quickly. The decision to opt for the netX 90 proved to be the right one for us.
