As an energy meter, energy is the main output of the DCBM. Two types of energy registers are
available:
• Total energy registers
• Transaction energy registers
As regard to certication of concerned product, the o󰀩cial registers to be used for billing are the
following:

transactionDuration
Transaction duration in seconds
energyImport
Import DC energy during the transaction
energyExport
Export DC energy during the transaction

Both sets of registers consist in two registers: Import energy and export energy (see "5.3. Energy
registering"). They are always displayed and stored together.
A single transaction stores both import and export energy values.

Total energy registers are available:
• in the /livemeasure API (see §7.1)
• on Idle screen
• on dedicated maintenance screens (Livemeasure category)
• in the transaction data structures (both /ocmf and /legal) and on transaction screens, as frozen
values corresponding to the start and end of the transaction
