I would be cautious using the internal flash memory.
The flash memory has a limited no of write cycles.
I dont know about the integrated flash memory in S7-1200, but for SMC cards it is typically 500000 write cycles: https://support.industry.siemens.com/cs/dk/en/view/109482591
For example, if you write every minute 24/7, you will hit that after 347 days.
