As described above, the application can be copied to the flash card after downloading. In order to store process data gathered during operation, there is a facility to copy texts or DBs from extension memory (address ≥ 4000) to the flash card, or conversely, to copy the last state written to the flash card back in the text/DB in extension memory.The memory space required to back up the DBs (extension memory backup) must be configured in the "Memory" tab in hardware settings.3Memory tabOn the Memory tab, the Extension Memory Backup Size can be set. This memory size represents the memory space for the "Copy program to flash" function. On the left-hand side, the currently available memory space for the user program is displayed.If the "extension memory backup size" is increased, the "user program backup size" will be automatically reduced (by twice the configured "extension memory backup size")
