Logbook
The logbook is intended to record the history of the
UH50
. Its content is permanently stored on
EEPROM and can only be deleted by initializing the EEPROM (only possible in the factory, not
by the customers or external testing facilities)
The
event memory
stores the data of the last events (with time stamp) in chronological order.
The
monthly memory
(implemented as a circulating buffer) stores the events of the last 18
months.
Only internal: Updating is performed on each full minute and transfer into the EEPROM on each
detected change.
The previous month’s values are held in the RAM and are transferred into the EEPROM on the
next full hour.
The
events
recorded are predefined and are logged with the time when they occurred.
Types of events:
−
Errors
−
Events (states or actions)
Types of events:
−
Occurrence/back-to-normal
(“KG”);
a change of
state
is recorded (14 different events)
−
Occurrence/acknowledgment
(“KQ”);
the occurrence of an
action
is recorded (10 different events)
