DLMS Direct Connect


Power Line Carrier (PLC) based systems are proving an attractive and cost-effective solution for Smart Metering deployments in the residential domain. In Europe, PLC solutions have already been implemented widely in some countries, while others are at an advanced stage of planning for large-scale roll-out. While typical approaches to PLC-based Smart Meter Systems are identical, there are differences in the underlying technology employed in each market – namely in respect of the physical modulation of and access to the carrier signal itself.

In this paper, Elster elaborates on the different elements that require attention within a PLC-based Smart Metering infrastructure, and presents the DLMS Direct Connect concept as a technology enhancement to conventional Data Concentrators that will resolve several of the key challenges posed by current Smart Metering architectures.
