Error Properties
The following error properties are recognized and memorized inside the devices:
▪ Error type (device label “error_type_rotate”):
e.g. “below_threshold” for a violation of the minimum voltage range defined
in the configuration, “shortcut_Batt” for a shortcut to battery voltage etc.
▪ Error locations (device label “error_location_rotate”):
e.g. “ANA01” for an error concerning the first ANA channel
▪ Error durations
For how long a period has the error been active? If an error encounters a
non‐active period before being cleared from the memory and is then detec‐
ted again, the error duration keeps on accumulating. The number of active
periods can be seen from the “number of occurrences”.
▪ Number of occurrences
How many times has the error been detected since the last time the error
memory was cleared.
▪ Error active state (device label “error_active_rotate”)
All failure modes are continuously diagnosed; any error detected will be writ‐
ten to the error memory. Once an error is detected, it is qualified as “active”.
– 1 (TRUE) Error was detected in most recent diagnose run (active)
– 0 (FALSE) Error is inactive: error was not detected in most recent diagnos‐
tic run, however the error has not been cleared from the memory by the
user and remains in the non‐volatile memory
The aforementioned labels (error_active_rotate, error_location_rotate, er‐
ror_type_rotate) are device properties (e.g. C 60) and are not error properties
(e.g. “error no. 3 from the error memory”). As a consequence, only one property
label is available in each device. The errors from the error memory (possibly more
