Power‑up scenarios for non‑volatile SIMOTION data
Case
Initial condition
Result
1
The non-volatile SIMOTION data is valid.
SIMOTION D4x5‑2 powers up with the non-volatile SIMO‐
TION data, i.e. with the PROFIBUS address in the non-
volatile data.
2
The non-volatile SIMOTION data is invalid and there
is no backup file (PMEMORY.XML) and no backup
copy of the backup file (PMEMORY.BAK).
SIMOTION D4x5‑2 copies the default settings to the non-
volatile SIMOTION data and powers up with this data. In
this case, for example, the default PROFIBUS address is
used.
3
The non-volatile SIMOTION data is invalid, backup file
(PMEMORY.XML) exists and is valid.
SIMOTION D4x5‑2 copies the backup file contents to the
non-volatile SIMOTION data and powers up with this data.
4
The non-volatile SIMOTION data is invalid, the backup
file is invalid and there is no backup copy of the backup
file (PMEMORY.BAK).
SIMOTION D4x5‑2 copies the default settings to the non-
volatile SIMOTION data and powers up with this data, in
which case, for example, the default PROFIBUS address
is used.
5
The non-volatile SIMOTION data is invalid; a backup
file exists, but it is invalid; a backup copy of the backup
file exists and is valid.
SIMOTION D4x5‑2 copies the backup file contents to the
non-volatile SIMOTION data and powers up with this data.
Non-volatile SIMOTION data diagnostics
The user can determine the state of the non-volatile SIMOTION data and the battery using the
diagnostic buffer, system variables, and PeripheralFaultTask.
Evaluating via the diagnostic buffer
When they are issued, the following messages are entered once in the diagnostic buffer:
Table 5-4
Messages of the diagnostic buffer
Entry
Meaning
Remedy
Level 1 battery voltage warning
1)
Battery voltage below prewarning lev‐
el.
Replace battery in the fan/battery mod‐
ule
Level 2 battery voltage warning
1)
The battery voltage is below the warn‐
ing level, backup of real-time clock
(RTC) can no longer be guaranteed.
Replace battery in the fan/battery mod‐
ule
Battery voltage for data backup in permis‐
sible range
The battery voltage is in the permis‐
sible range for the backup of the real-
time clock (RTC).
Non-volatile data memory voltage error
The buffer voltage of the SuperCap
or the battery was too low after
switching on. Possible data loss in
the real-time clock.
Replace battery in the fan/battery mod‐
ule or charge the SuperCap over a lon‐
ger period.
Non-volatile data loaded from a file
(Persistent Data File Loading done)
Non-volatile SIMOTION data has
been successfully restored from the
backup file on the CF card.
