7.1.
Energy counter overflow
The max value reached by each Energy variable counters is 9 999 999, 999 after that a new increment of
0,001 will reset the counter to 0,000.
7.2.
Non volatile memory Energy backup
The following Energy variables are write on a non-volatile memory (using a Fe RAM technology):
Integer and fractionary part of phase A positive Energy
Integer and fractionary part of phase B positive Energy
Integer and fractionary part of phase C positive Energy
Integer and fractionary part of phase A negative Energy
Integer and fractionary part of phase B negative Energy
Integer and fractionary part of phase C negative Energy
Integer and fractionary part of phase A positive Reactive Energy
Integer and fractionary part of phase B positive Reactive Energy
Integer and fractionary part of phase C positive Reactive Energy
Integer and fractionary part of phase A negative Reactive Energy
Integer and fractionary part of phase B negative Reactive Energy
Integer and fractionary part of phase C negative Reactive Energy
The energy values are written with a round robin policy. Each energy value is written at most every 2
seconds.
