Removing the SIMATIC memory card
To remove a SIMATIC memory card, follow these steps:
1.
Open the front cover.
2.
Switch the CPU into STOP mode.
3.
Press the SIMATIC memory card into the CPU with light pressure. After audible
unlatching of the SIMATIC memory card, remove it.
Only remove the SIMATIC memory card in POWER OFF or STOP mode of the CPU. Ensure
that no writing functions (online functions with the programming device, e.g. loading/deleting
a block, test functions) are active in STOP mode or were active before POWER OFF.
If you remove the SIMATIC memory card during a write process, the following problems can
occur:
●
The data content of a file is incomplete.
●
The file is no longer readable, or no longer exists.
●
The entire content of the card is corrupted.
Also note the following FAQ on the Internet

) in connection with the
removal of the SIMATIC memory card.
Reactions after removing/inserting the SIMATIC memory card
Inserting and removing the SIMATIC memory card in STOP mode triggers a re-evaluation of
the SIMATIC memory card. The CPU hereby compares the content of the configuration on
the SIMATIC memory card with the backed-up retentive data. If the backed-up retentive data
matches the data of the configuration on the SIMATIC memory card, the retentive data is
retained. If the data differs, the CPU automatically performs a memory reset (which means
the retentive data is deleted) and then goes to STOP.
The CPU evaluates the SIMATIC memory card and indicates this by flashing the RUN/STOP
LED.
Reference
You can find additional information on the SIMATIC memory card in the section SIMATIC
memory card (Page 259).
