Smart Grid Nodes enable remote DNP3 data aggregation and control.

Press Release Summary:

Ambient Smart Grid® Nodes fully support DNP3 protocol, enabling local data aggregation and control at distributed locations on utility grid. Nodes can act as slave to Network Operations Center (NOC) master or as master to communicate with and control multiple IEDs slaves. Use of local computing power on each node enables local decision-making and action as well as communication of select data back to centralized NOC.

Ambient Smart Grid Nodes Enable Remote DNP3 Data Aggregation and Control for SCADA and Distribution Automation Applications

Communications and applications platform avoids stranding assets and provides for the future with multiple protocol support

HOUSTON and NEWTON, Mass. -- Ambient Corporation (NASDAQ: AMBT), provider of a secure, flexible, and scalable communications and applications platform, today announced that all Ambient Smart Grid(®) Nodes fully support DNP3 protocol, which enables local data aggregation and control at distributed locations on the utility grid.

DNP3 protocol support allows the Ambient Smart Grid Nodes to collect, process, store, communicate, and act on data from DNP3-enabled Intelligent Electronic Devices (IEDs) used on the grid. The nodes can act as both "slave" to the Network Operations Center (NOC) "master," and a "master" to communicate with and control multiple IEDs "slaves." The use of local computing power on each and every node enables local decision-making and action, and/or communication of selected data back to the centralized Network Operations Center - a versatile solution for multiple grid scenarios.

"Facilitating multiple smart grid applications, in parallel, is a pillar of Ambient's solution, and we recognize that existing assets are a significant part of the grid and will be for years to come. Being able to cost-effectively combine existing and new assets in any grid modernization plan, using a common communications and applications platform, avoids single-use networks and reduces unnecessary cost," said Ram Rao, Senior Vice President and Chief Technology Officer at Ambient Corporation.

Ambient Corporation helps utilities modernize the grid with IP-based networking products and applications that integrate and connect existing and future grid assets on a secure, flexible, and scalable smart grid communications platform. Ambient's Smart Grid Node family enables real time data communication for multiple applications, in parallel:  smart metering, distributed generation and storage, demand response, and distribution automation.
