6.2.4 SIMATIC Memory Card

A SIMATIC Micro Memory Card is used as memory module. This card is a pre-formatted memory card
compatible with the Windows file system. It is available in different memory sizes and can be used for
the following purposes:
● Transportable data carrier
● Program card
● Firmware update card

To operate the CPU, the MMC must be inserted because the CPUs do not have an integrated load

memory. A commercially available SD card reader is necessary to write to/read the SIMATIC memory
card with the PG/PC. It is used, for example, to copy data with the Windows Explorer directly to the
SIMATIC memory card.

Note:

We recommend inserting the SIMATIC memory card into the CPU or removing it only in the POWER
OFF mode.

6.2.5 Operating Mode Switch

With the operat

ing mode switch, we can set the CPU’s current operating mode. The operating mode

switch is designed as toggle switch with three switching positions:

Under Online & Diagnostics, the operating mode (STOP and RUN) can also be switched with the button

on the CPU operator panel of the STEP 7 Professional V13 software.

In addition, the operator panel includes a button MRES for a general reset and displays the

CPU’s status

LEDs.
