In addition to the diagnostic data, non-volatile SIMOTION data (retain data) is also saved on
the CompactFlash card. You can use these in situations where the non-volatile SIMOTION
data has not been saved on the CompactFlash card using the _savePersistentMemoryData
system function, and you wish to restore the non-volatile SIMOTION data after a CPU has
been replaced.
Note
While the non-volatile SIMOTION data is stored as a "PMEMORY.XML" backup file in the
"...USER\SIMOTION" directory using the _savePersistentMemoryData system function,
backing up diagnostic data and non-volatile SIMOTION data stores the data in the
"...\USER\SIMOTION\HMI\SYSLOG\DIAG directory.
