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.

- DALI-2 (IEC 62386 Edition 2, 2014+) is the major evolution of DALI v1, adding native support for input devices (sensors, push-buttons) directly on the DALI bus itself, together with a product certification programme administered by the DALI Alliance (DiiA).1. Architecture · DALI vs DALI-2
- The DALI bus uses a polarity-free twisted pair (no + / - orientation), with Manchester coding at 1 200 baud over a nominal 22.5 V DC supply, and is allowed to share the same multi-core cable as the 230 V mains feeding the luminaires.1. Architecture · Physikalische Schicht
- Self-contained emergency luminaires (DT1) under DALI-2 support standardised commands for the monthly function tests and annual duration tests required by EN 50172, and these tests can be automated from a central DALI-2 controller.2. Devices · Typ 1 Notbeleuchtung
- DALI-2 supports several application controllers active on the same bus (multi-master), with an arbitration mechanism that prevents conflicts when two controllers try to command the same control gear at the same time.4. Application Controllers · Multi-Master
- DALI bus power supplies are typically available at 100, 120, 150 or 250 mA depending on the vendor (ABB BCO/S, Tridonic DALI-PS, Lunatone PS5), and should be sized for the cumulative current of control gear plus input devices, with a 30 percent margin.7. Best practices · Bus-Netzteil
