3.11: Type F11 Energy Counter (Packed BCD / Secondary)

Length: 4 Registers (8 bytes)

Range: 9,999,999,999,999,999 / 0 VAh, VARh or Wh secondary

Unit: 1 VAh, VARh or Wh secondary

These registers contain 8 bytes of Packed BCD. Each register contains 2 bytes. Each byte contains 2 nibbles. Each nibble represents a decimal digit from 0-9. All together, there are 16 nibbles, and therefore a 16-digit decimal number can be represented.

Example:

Registers 00982 – 00985, VAhour, might contain the following data:
