KNX Protocol Simplifies Network Extension For Smart Buildings

Renesas Electronics has implemented the KNX protocol on its G3-PLC powerline communication (PLC) solution. According to the company, combining data line and power line onto one cable system and using the most efficient modulation techniques, PLC is a cost-efficient way to expand connectivity through the building over long distances and across the walls. Primarily developed for energy metering applications, the G3-PLC protocol is freely usable as an open standard and continuously maintained by the G3-PLC Alliance.

 

The Renesas Powerline Modem Solution comprises Renesas’ OFDM PLC software modem (R9A06G037), a Renesas Synergy microcontroller (MCU) and the ISL15102, which serves as the power line driver. The software stack is based on the Synergy Software package (SSP) and combines the Renesas G3-PLC stack with a KNX software stack provided by Tapko Technologies GmbH. The proof of concept allows customers to build KNX over the G3-PLC protocol, offering a smooth migration path from existing KNX standard towards upcoming KNX IoT standard.

G3-PLC is a protocol for narrow band low frequency powerline communication that facilitates high-speed, highly-reliable, long-range communication over the existing powerline grid. The protocol is developed and maintained by the G3-PLC Alliance as a potentially ubiquitous powerline communications standard to enable the smart grid vision.

 

The Renesas G3-PLC Modem Solution with complete set of software supporting KNX Protocol will be available in Q3, 2019. For more info, visit Renesas Electronics Corporation.
