• log# values: 0 = system log, 1 = alarms log, 2-4 = historical logs 1-3, 5 = I/O
change log
• sector# values: 0-63
• slot# values: 1-2
NOTES:
• Stimulus for a flash sector error indicates what the flash was doing when the error
occurred: 1 = acquire sector, 2 = startup, 3 = empty sector, 4 = release sector, 5 =
write data
• Flash error counters are reset to zero in the unlikely event that both copies in
EEPROM are corrupted.
• A "babbling log" is one that is saving records faster than the meter can handle long
term. Onset of babbling occurs when a log fills a flash sector in less than an hour.
For as long as babbling persists, a summary of records discarded is logged every 60
minutes. Normal logging resumes when there have been no new append attempts
for 30 seconds.
• Logging of diagnostic records may be suppressed via a bit in programmable
settings.
Alarm Record:
Size: 10 bytes (16 bytes image)
Data: The Alarm record data is 4 bytes, and specifies which limit the event occurred
on, and the direction of the event (going out of limit, or coming back into limit).
