<![CDATA[DLMS/COSEM Prepayment Balance Accounting: Class 72 (Account Interface) Explained]]>Real-Time Balance & Multi-Currency Prepayment with Class 72

Class 72 (Account Interface, OBIS 0.0.19.0.0.255) manages real-time monetary balances, debt recovery schedules, and tariff currency conversions directly inside the smart meter.

Essential Attributes

  • Attribute 2 (account_status): Enum (Active, Suspended, In-Debt, Emergency-Credit-Active).
  • Attribute 3 (current_credit_amount): Scaler-Unit formatted monetary value (e.g. 5000 with scaler -2 = $50.00).
  • Attribute 4 (credit_configuration): Defines emergency credit limits and daily standing charges.
  • Attribute 7 (charge_schedule): Periodic deduction rules (e.g. grid access fee per 24 hours).

When credit falls below zero, Class 72 invokes Method 1 on Class 70 (Disconnect Control) to safely disconnect the load after notifying the customer.
