A129 129 ParRestored Parameter restored:
The parameters found in the flash were invalid at power-
up (checksum fault). All parameters were restored from
the parameter backup.

A131 131 ParAdded Parameter added:
A new firmware with a different amount of parameters was
downloaded. The new parameters are set to their default
values. The parameters causing the alarm can be
identified in Diagnosis (9.11). Check:
−
new parameters and set them to the desired values

A132 132 ParConflict
Parameter setting conflict:
Is triggered by parameter settings conflicting with other
parameters. The parameters causing the alarm can be
identified in Diagnosis (9.11).

A133 133 RetainInv Retain data invalid:
Set when the retain data in the flash are invalid during
power-up. In this case, the backup data are used.
Note:
The backup of the lost retain data reflects the status at the
previous power-up.
Examples for retain data are:
−
fault logger data,
−
Data1 (19.01) to Data4 (19.04) and
−
I/O options (see group 98)
The situation of invalid retain data occurs, if the auxiliary
voltage of the DCS550 is switched off about 2 seconds
after power-up (while the retain data sector is being
rearranged). Check:
−
if the flash of the SDCS-CON-F is defective and
−
if the auxiliary power supply has a problem

A134 134 ParComp Parameter compatibility:
When downloading parameter sets or during power-up the
firmware attempts to write the parameters. If the setting is
not possible or not compatible, the parameter is set to
default. The parameters causing the alarm can be
identified in Diagnosis (9.11). Check:
−
