<![CDATA[COSEM Class 21 (Register Activation) for Dynamic Tariff Masking & CPP Rate Adjustments]]>Grouping and Activating Energy Registers with Class 21

Class 21 (Register Activation) dynamically maps raw measurement values into specific billing rate registers based on digital input signals or schedule triggers.

Configuration Structure

  • register_assignment (Attribute 2): Array linking base measurement OBIS codes (e.g. 1.0.1.8.0.255) to tariff registers (1.0.1.8.1.255, 1.0.1.8.2.255, 1.0.1.8.3.255).
  • mask_list (Attribute 3): Defines active tariff masks for Rate 1 (T1), Rate 2 (T2), and Rate 3 (T3).
  • active_mask (Attribute 4): Currently energized tariff mask.
