Renesas enhances PLC network layer

Designed to specifically address requirements for efficient communication over smart metering networks, the Renesas PLC solution comprises a physical layer, a data link layer and Run-M, the Renesas ubiquitous network layer for metering.

The features of Run-M include intelligent network setup (plug and play), self-healing capabilities (response to changing field conditions), intelligent repeating mechanisms (ensuring optimal communication), and unique NWK topology memory (to minimise unnecessary network traffic).

The updated version, Run-M2.1, offers a number of additional features for smart metering customers.

Line quality information is provided to the application to allow network statistics to be intelligently used for communication path analysis and management.

Cross-network communication enables communication between different logical networks, allowing comfortable access of hand-held units to meters/nodes within range for manual read out/control and simplified load balancing management through communication between concentrators.

Impostor detection prevents the network from sharing information with intruders and helps avoid the use of the same NWK and node ID within range.

Adjustable gain control allows a more energy-efficient communication.
