Data Concentrator Unit
The ANG100 is an AetherNexus™ data concentrator unit (DCU) for advanced metering infrastructure. It reads meters on a schedule over a plug-in down-link module (G3-PLC, BPLC, BPSK or RF), stores the data and exchanges it with the head-end system over a plug-in 2G, 3G or 4G cellular up-link module, using DLMS/COSEM. The values on this page come from the Rev1.0 user manual, a draft for approval.

Key features
- Plug-in down-link module (G3-PLC, BPLC, BPSK or RF) and plug-in up-link module for 2G, 3G or 4G cellular networks.
- DLMS/COSEM and IDIS 2.0 support for interoperability with the meters.
- Two operating modes, gateway and scheduled task reading, with concurrent meter reading over different communication channels.
- Scheduled pull and push tasks based on flexible cron expressions; event and alarm monitoring and data storage.
- Local maintenance through the DCU web portal over Ethernet; local or remote software upgrade.
DCU functions
Up-link communication
- DLMS-compatible communication with the HES in server mode (SIM card with a static IP address) or client mode, for meter archive management, DCU information and time synchronisation, on-demand meter operations, collection of meter data and firmware upgrades.
Down-link communication
- DLMS/IDIS2 communication with the meters: scheduled reading of load profiles, daily and monthly frozen data and meter events; forwarding of on-demand HES requests; meter and module firmware upgrades.
Firmware upgrade
- DCU firmware upgrade via the HES or from a USB flash drive; meter firmware upgrade via the DLMS protocol; communication-module upgrade via an internal protocol.
Security
- Encryption of all communication channels to the HES and to the meters, with AES-128 and AES-256.
DCU events
- Events such as software start-up, meter registration and parameter changes are stored in the internal memory and pushed to the HES.
Maintenance
- LED status indicators (legend assignment being confirmed), a traceable log and a local web portal for meter archives, communication parameters, channel attribution and task plans.
