Siemens joins up with smart meter manufacturer EMH

November 9, 2010 | By Craig Pearson

In the lead-up to making its meter data communication protocol AMIS DLC available to the public in January 2011, Siemens Energy is working with EMH Metering GmbH & Co. KG (Wittenburg, Germany) in the field of smart metering.

“This cooperation agreement is a further step toward open communication in the context of smart metering,” said Richard Hausmann, CEO of the Siemens Company Project Smart Grid Applications.

By opening its previously proprietary Distribution Line Carrier communication protocol (DLC) for public use in January 2011, Siemens is creating an option for connecting meters made by other manufacturers with its automated metering and information system (AMIS). The aim with the EMH partnership is to integrate this manufacturer’s meters into the AMIS system so as to be able to offer an all-round smart metering solution.

“Siemens and EMH are two skilled partners with innovative system solutions and products who are ready and willing to assist power providers and grid operators with their smart metering projects,” added Hausmann.


The DLC communication protocol developed by Siemens Energy especially for providing smart metering and smart grid solutions can cope with all kinds of changes in the physical communication parameters of a low-voltage distribution network, such as signal damping, noise, network disturbances, signal coupling and network configuration changes. In this way, the DLC protocol promises 100% availability to this communication technology. It also ensures smooth, trouble-free functioning of smart metering solutions within smart grids.

Furthermore, the application offers ample scope for the integration of future smart grid functions, says Siemens, and enables the incorporation of an existing network automation structure based on IEC protocols.
