test functions) were active before POWER OFF.
Removing and inserting a SIMATIC memory card
If you replace the SIMATIC memory card, the CPU detects:
● A physically identical SIMATIC memory card with modified content
● A new SIMATIC memory card with the same content as the original SIMATIC memory
card
After POWER ON, the CPU automatically performs a memory reset.
