05 Multi-HES Adapter Framework KEY DIFFERENTIATOR

Each DISCOM tender involves ~3 HES vendors supplying meters. Our Multi-HES Adapter Framework provides unified integration with configurable OBIS code mapping per vendor.

MDM is the Brain - HES is Data Source

The MDM platform orchestrates all meter data operations. Multiple HES systems feed data through our adapter framework, which normalizes data formats and OBIS codes to provide a unified view regardless of vendor.

Adapter Architecture Pluggable adapter per HES vendor - Add new vendors without core code changes
OBIS Code Mapping Configurable mapping per vendor - Same data field may have different OBIS codes across vendors; adapter normalizes to standard format
Protocol Support REST API / MQTT / DLMS-COSEM / Proprietary protocols (per vendor requirements)
Data Normalization Timestamp alignment, unit conversion, data quality flags - unified regardless of source
Data Push Each HES pushes readings to MDM on configurable intervals (default: 15 minutes)
Data Pull MDM can query any connected HES for on-demand reads and historical data
Command Routing MDM routes commands (disconnect, reconnect, on-demand read) to correct HES based on meter mapping
Event Aggregation Real-time event forwarding from all HES vendors to unified event processor
Security Per-vendor API keys + IP whitelisting + TLS 1.3 encryption
HPL HES (Native):

Primary adapter for HPL's own meters. Our team will work with HPL's HES team during Discovery phase to develop native connector with full API access.

Third-Party HES:

Generic adapters for other HES vendors in tender. Configurable OBIS mapping and protocol settings per vendor without code changes.
