Commissioning (hardware)
2.5 User memory concept
To save the configuration data changed online to the offline project, you must first transfer
the content of the current RAM to the RAM using the menu command "Target system" >
"Copy current data to RAM".
Once you have done this, the configuration in SCOUT will no longer be consistent with the
configuration in the target device, as a consistency check is performed on the RAM data.
Read the data from the RAM using the menu command "Target system" > "Load" > "Load
CPU / drive unit to PG" (for the configuration data only) to re-establish a consistent system
state.
To save the configuration on the CompactFlash Card with protection against power failures,
execute the menu command "Target system" > "Copy RAM to ROM".
Via the menu "Options" > "Settings ..." > "Download", you can set whether current values are
to be copied to the RAM and configuration data loaded to the PG with "Copy RAM to ROM"
using the option "Transfer current values to RAM with copy RAM to ROM".
Note
The "Copy current data to RAM" command does not transfer the values of the system
variables to the RAM memory. This means that "Save to memory card (Copy RAM to ROM)"
or "Save in the engineering project (Load CPU / drive unit to PG)" is not possible.
In order to ensure that system variable values can also be saved to the engineering project
and memory card, the system variable values must be changed OFFLINE and then
downloaded to the target device and saved.
Startup of SIMOTION D410
The SIMOTION kernel is loaded from the CompactFlash Card to the "volatile SIMOTION
data" area during startup of SIMOTION D410.
Volatile SIMOTION data is lost if you shut down the SIMOTION D410 module after the
download. With a subsequent power-up, the following data is loaded from the CompactFlash
Card:
● Technology packages and user data to the "volatile SIMOTION data" area
● IP and DP parameters to the "non-volatile SIMOTION data" area
