Renesas Electronics simplifies automation network for buildings

At this year’s Embedded World, Renesas Electronics will show a proof-of-concept G3-PLC modem with KNX protocol that is claimed to simplify building automation for smart buildings.

The company has implemented KNX protocol on its G3-PLC powerline communication (PLC) solution. Based on the Powerline Modem Solution, Renesas will demonstrate a proof of concept to illustrate how to implement KNX networks and take advantage of the flexibility and efficiency of modern G3-PLC technology while eliminating the need for new network cable deployment.

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 in particular over long distances and across the walls.

Most commercial buildings have areas where RF and tradition network cabling do not reach. The Renesas Powerline Modem Solution demonstrates the possibilities for G3-PLC technology to address these needs without requiring new cable deployment by combining the advantages of the open G3-PLC standard with the popular KNX protocol. The result, says Renesas, will enable the deployment of reliable and cost-effective networking solutions for HVAC, lighting, fire and safety, and building access security.

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. 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.

The Renesas G3-PLC Modem Solution with complete set of software supporting KNX Protocol will be available in Q3, 2019.
