Question
The D4i Memory Banks (MB201-MB206) extend DALI-2 with smart-city lifecycle data: MB201 luminaire diagnostic, MB202 asset info, MB203/204 energy data (cumulative kWh and instantaneous W), MB205 features and MB206 control-gear health.
Answer
True
The D4i 'smart luminaire' memory banks comprise: MB201 Luminaire Diagnostic and Maintenance; MB202 Luminaire Asset (GTIN, mounting, position); MB203 Energy Data; MB204 Energy Total Consumption; MB205 Luminaire Features (colour, lumen, etc.); MB206 Control Gear Health. Together they enable per-luminaire real-time telemetry to a smart-city platform, and have become the standard for new outdoor lighting deployments.
Preparation tip
Confirm at procurement which D4i memory banks the driver actually populates — a 'D4i' label is no guarantee that MB203 energy data is implemented.
