SIMATIC memory card - Overview

Introduction
The automation system uses a SIMATIC memory card as the program memory. The
SIMATIC memory card is a preformatted memory card compatible with the Windows file
system. The memory card is available in different memory sizes and can be used for the
following purposes:
● Transportable data carrier
● Program card
● Firmware update card
● Service data card
When you transfer the user program to the CPU via an online connection, it is written to the
SIMATIC memory card. The SIMATIC memory card must be in the card slot of the CPU for
this.
You can also write the SIMATIC memory card in the programming device or PC. A
commercially available SD card reader is needed to read or write the SIMATIC memory card
with the programming device or PC. You use this, for example, to copy files directly to the
SIMATIC memory card with Windows Explorer.
The SIMATIC memory card is mandatory for operation of the CPU.
Note
SIMATIC memory cards of the redundant system S7-1500R/H
For the redundant system S7-1500R/H you need a SIMATIC memory card for each of the
two CPUs. During redundant operation, both CPUs access the memory cards.
