Operator actions and their impact on user memory
The operator actions and their effects on the user memory are described below.
These operator actions are marked with arrows in the following displays:
●
Figure 2-2 SIMOTION D410 memory model (Page 33)
●
Figure 2-3 Configuration data and system variables on volatile memory (Page 36)
SIMOTION SCOUT download
The following data is transferred by means of the menu command "Load project to target
system" or "Load CPU / drive unit to target device" from the engineering system to the
"volatile SIMOTION data" area:
●
User data (units, configuration data, parameter assignments, task configuration)
●
Technology packages (TPs)
The IP and DP parameters are furthermore saved to the "non-volatile SIMOTION data" area.
The retain variables are set to their initial values, but this depends on the settings in
SIMOTION SCOUT. Volatile SIMOTION data is lost if you shut down the SIMOTION D410
module after the download.
Copy RAM to ROM
The "Copy RAM to ROM" command is used on the ES to save the following data to the
CompactFlash Card:
●
Technology packages and user data (units, configuration data, parameter assignments,
task configuration) from the "volatile SIMOTION data" area
●
Current values are copied to the "volatile SIMOTION data" area, depending on the
settings in SIMOTION SCOUT.
Note
The "Copy RAM to ROM" menu command does not save the current values of the retain
variables to the CompactFlash Card. For this purpose, use the
_savePersistentMemoryData system function.
Note
The "Copy RAM to ROM" function is also available for drive units and saves the volatile
SINAMICS data to the non-volatile memory (CompactFlash Card).
Current RAM
If you change the system variable values, these take immediate effect in the current RAM.
New configuration data values are initially stored in the Next memory. Configuration data that
take immediate effect are automatically transferred to the current RAM. Configuration data
that will only become active following a RESTART on the technology object (set the
restartactivation system variable to the ACTIVATE_RESTART value) are only written to the
current RAM once the RESTART has taken place.
