ZIV DCUs include an advanced low voltage supervisor and Powerline Communication (PLC) controller with network monitoring functions, in addition to remote smart meter management functions.
Smart meter management
The main function of a Data Concentrator Unit (DCU) is to continuously poll the metering devices connected to the same secondary substation where it is connected. The retrieved meter data is stored in the DCU and periodically sent to the Management System.ZIV DCU model implements identification and removal of meters (plug and play), supervision and control, synchronization of meters, programmable tasks, and many other functions.
PLC communications controller
They implement protocols widely accepted in smart metering such as DLMS to carry readings and web services to communicate with the utility MDM frontend.
The low voltage supervision function is performed by an internal three-phase energy meter, monitoring the secondary of the distribution transformer. 4CCT offers easy interaction with this meter, similar to the other meters in the network.
