Operations and their effect on the 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 5-2 SIMOTION D410-2 memory model (Page 86)
● Figure 5-3 Configuration data and system variables in the volatile memory (memory
concept, principle) (Page 89)
SIMOTION SCOUT download
The following data are transferred with "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 settings, task configuration)
● Technology packages (TPs)
In addition, the IP and DP parameters are 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. If the SIMOTION D410‑2 is switched off following the download, the volatile
SIMOTION data are lost.
Copy RAM to ROM
The Copy RAM to ROM menu command saves the following data via the engineering system
to the CF 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 CF card. Use the system function "_savePersistentMemoryData" for this.
Note
The "Copy RAM to ROM" function is also available for drive units and saves the volatile
SINAMICS data to the non-volatile memory (CF 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) is not written to the
current RAM until after the RESTART.
