Procedure with the SIMATIC memory card
Proceed as follows to perform a firmware update using the SIMATIC memory card:
1. Insert a SIMATIC memory card into the SD card reader of your PG/PC.
2. To store the update file on the SIMATIC memory card, select the SIMATIC memory card
under "Card reader/USB memory" in the project tree.
3. Select the "Card Reader/USB memory > Create firmware update memory card" command
in the "Project" menu.
4. Use a file selection dialog to navigate to the firmware update file. You can then also
decide whether to delete the content of the SIMATIC memory card or add the firmware
update files to the SIMATIC memory card.
5. Insert the SIMATIC memory card with the firmware update files into the CPU.
The firmware update begins shortly after the SIMATIC memory card has been inserted.
The display indicates that the CPU is in STOP and is running a firmware update.
The display shows a results screen after completion of the firmware update.
6. The RUN LED on the CPU lights up in yellow and the MAINT LED flashes yellow.
Remove the SIMATIC memory card after the firmware update is complete.
If you subsequently wish to use the SIMATIC memory card as a program card, leave the
SIMATIC memory card in the CPU. To do so, after completion of the firmware update,
select the "Convert memory card" menu item on the display.
Alternatively, you can also convert the SIMATIC memory card to a program card in STEP 7.
