Distributed Control Node (DCN) 3000 Series

The Networked Energy Services (NES) Distributed Control Node is a data concentrator and a powerful computing platform in one. As a data concentrator, it manages smart meters and other smart grid sensors on the low-voltage distribution grid using power line communication based on OSGP, connecting them through the WAN to NES System Software. Beyond its role as a ruggedized OSGP PLC Data Concentrator, the DCN also provides a flexible and secure Linux-based application platform for future functionality expansion and evolving standards support.

  • Automatically discovers meter, segment, feeder and transformer associations using Low Voltage Grid Mapping (LVGM) feature and reports them up to the head-end system. Can identify connection of actual phase for devices in its portion of the LV grid  
  • Communicates with the NES System Software using any wired or wireless IP-capable network and supports data authentication and encryption on all data channels. Includes enhanced connectivity and modularity via USB.
  • Supports fast commissioning of supported OSGP meters in a single message exchange. Collects and reports meter and other sensor data, including consumption and power-quality measurements.
  • Monitors and reports a variety of alarm conditions, including outages, possible fault conditions and tampering.
  • Linux OS supports remotely and securely adding distributed applications and device/sensor support drivers in the field.
  • Enjoy daily communication reads delivered with 99.7- 100% reliability using OSGP (Open Smart Grid Protocol) power line technology; this technology enables four times the bandwidth of second-generation RF and is used by more smart meters than any other data concentrator in the world.
  • Resistant to vandalism and extreme weather; Translucent cover and status LEDs provide diagnostics for easier installation

The Networked Energy Services (NES) system is an open, extensible, field-proven platform for managing millions of commercial, consumer, and utility smart grid devices. The system uses our patented power line technology to communicate over the existing power line carrier system. It includes:

Echelon System Software
A secure network operating system that includes powerful application programming interfaces (APIs) for configuring, provisioning, installing, controlling, diagnosing, and reporting on NES devices, including smart meters.

Element Manager
Browser-based network-analysis software that provides visual statistics, automated-network and user-rights management, auditing, logging, and time-saving diagnostics for millions of smart grid devices. Element Manager makes it possible to solve problems in real time.

NES Smart Meters
ANSI and IEC commercial and residential meters with extensive metering capabilities, software-controlled disconnect switch, and information display. NES smart meters have been field-proven to be 99.5% reliable.

CPM 6000 - Control Point Module for Smart Grid Devices
An embedded module that enables manufacturers to add our proven power line technology to smart grid devices, such as solar panel micro-inverters, load-control modules, power-quality sensors, pool pumps, and electric-vehicle chargers.
