Removing SIMATIC memory cards
Proceed as follows to remove a SIMATIC memory card:
1. Open the front cover.
2. Switch the CPU to STOP.
3. Gently push the SIMATIC memory card into the CPU. Once it has clicked into place,
remove the SIMATIC memory card.
Only remove the SIMATIC memory card in the POWER OFF or STOP state of the CPU.
Ensure that:
● No writing functions are active in STOP. Writing functions are online functions with the
PG/PC, for example loading/deleting a block and test functions.
● No writing functions were active before POWER OFF
If you remove the SIMATIC memory card during a write process, the following problems can
occur:
● The data contents of a file are incomplete.
● The file is no longer readable, or no longer exists.
● The entire content of the card is corrupted.
Please also note the following FAQs on the Internet

memory card.
Note
If you switch a CPU in redundant mode to the STOP operating state, the S7-1500R/H
redundant system switches to the RUN-Solo system state. The other CPU maintains control
of the process.
