Properties of the user memories

Non-volatile data
Non-volatile data is used with the objective of retaining user- and system-relevant data when
SIMOTION D410 is in de-energized state. You will find information about the area that can
be used for non-volatile data in the
Non-volatile data available in SIMOTION devices:
Table 2- 1
Non-volatile data
Kernel data
Retain variables
Retain TO
DCC blocks
Note
DCC SIMOTION blocks with retain behavior act like retain variables in terms of copying RAM
to ROM, performing a memory reset, downloading, backing up non-volatile SIMOTION data
(_savePersistentMemoryData), and backing up data such as retain variables.
With DCC SINAMICS blocks, data are only backed up using FRAM, i.e. not
_savePersistentMemoryData.
For additional details, please refer to the
The SIMOTION D410 backed-up data have the following features:
