Inserting the SIMATIC memory card
To insert a SIMATIC memory card, follow these steps:
1. Ensure that the CPU is either switched off or in STOP mode.
2. Insert the SIMATIC memory card, as depicted on the CPU, into the slot for the SIMATIC
memory card.
Figure 10-7
3. Insert the SIMATIC memory card with light pressure into the CPU, until the SIMATIC
memory card latches.
Removing the SIMATIC memory card
To remove a SIMATIC memory card, follow these steps:
1. Switch the CPU to STOP mode.
2. Press the SIMATIC memory card into the CPU with light pressure. After audible
unlatching of the SIMATIC memory card, remove it.
Reactions after removing/inserting the SIMATIC memory card
Inserting and removing the SIMATIC memory card in STOP, STARTUP or RUN mode
triggers a re-evaluation of the SIMATIC memory card. The CPU 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 the RUN/STOP LED
flashing.
