Data Concentrator Unit (DCU) is an intelligent unit used to acquire data from multiple meters in a substation. DCU supports DLMS/COSEM protocol and can acquire data from a maximum of 20 meters. It is compatible with the meters manufactured by majority of Indian meter manufacturers. DCU polls the meters and acquires ABT parameters from all meters and stores it on DCU. Typical data stored includes load survey, midnight data, tamper data and event data from all meters. A maximum of 45 days of data of all 20 meters are stored.

The MDAS software at the control center accesses the stored data at schedule time or ON demand. The DCU reports the meter communication status to MDAS software for remote monitoring and diagnostics purpose.
