Operations and their effect on the user memory
The next section describes the operations identified in the "SIMOTION C memory model"
figure by arrows and their effect on the user memory.
SIMOTION SCOUT download
The "Download" command transfers the following data from the engineering system to the
"volatile data" area:
● User data (programs, configuration data, parameterizations, task configuration)
● Technology packages
The IP and DP parameters are also saved to the "non-volatile data". Depending on the
setting in SIMOTION SCOUT, the retain variables are set to their initial values.
The "volatile data" is lost if the SIMOTION C is switched off after a download without having
performed a "Copy RAM to ROM".
Copy RAM to ROM
The "Copy RAM to ROM" command is used on the engineering system to save the following
data to the MMC:
● Technology packages and user data (programs, configuration data, parameterizations,
task configuration) of the "volatile data" area
● Depending on the setting in SIMOTION SCOUT, actual values can be copied to the
"volatile data" area before copying the data from RAM to ROM.
Note
The "Copy RAM to ROM" command does not save the actual values of the retain
variables to the MMC.
SIMOTION C ramp-up
During ramp-up, the SIMOTION Kernel is loaded to the "volatile data" area. A C230-2 loads
the kernel from the "non-volatile system" (integrated flash in the device), a C240/C240PN
loads the kernel from the MMC.
The following data is also loaded from the MMC during ramp-up:
● Technology packages and user data to the "volatile data"
● IP and DP parameters to the "non-volatile data"
SIMOTION Kernel update (only valid for SIMOTION C230-2)
An update writes the SIMOTION Kernel from the micro memory card to the "non-volatile
system". If a newer or an older version of the SIMOTION Kernel is to be installed, an update
can be performed with a micro memory card that contains the appropriate SIMOTION
Kernel.
