Removing/plugging in SIMATIC memory cards

Requirements
For the S7-1500R/H redundant system, you need a SIMATIC memory card for each of the
two CPUs.
The CPUs only support pre-formatted SIMATIC memory cards. If required, format the
SIMATIC memory cards before using them in the CPU.
You can find more information on formatting SIMATIC memory cards in the function manual
Structure and use of the CPU memory
(https://support.industry.siemens.com/cs/ww/en/view/59193101).
Make sure that the SIMATIC memory cards of the two CPUs are not write-protected.
Inserting SIMATIC memory cards
Proceed as follows to insert a SIMATIC memory card:
1. Open the front cover of the CPU.
2. Make sure that the CPU is either switched off or in STOP operating state.
3. Insert the SIMATIC memory card, as shown on the CPU, into the slot for the SIMATIC
memory card.

4. Carefully insert the SIMATIC memory card into the CPU, pushing gently, until the card
clicks into place.
