Creating a program card
When used as a program card, the memory card is the external load memory of the CPU. If
you remove the program card, the internal load memory of the CPU is empty.
Note
If you insert a blank memory card into the CPU and perform a memory card evaluation by
either power cycling the CPU, performing a STOP to RUN transition, or performing a
memory reset (MRES), the program and force values in internal load memory of the CPU are
copied to the memory card. (The memory card is now a program card.) After the copy has
been completed, the program in internal load memory of the CPU is then erased. The CPU
then goes to the configured startup mode (RUN or STOP).
Always remember to configure the startup parameter of the CPU (Page 102) before copying
a project to the program card. To create a program card, follow these steps:
1. Insert a blank SIMATIC memory card into an SD card reader/writer attached to your

If you are reusing a SIMATIC memory card that contains a user program or a firmware
update, you must delete the program files before reusing the card. Use Windows Explorer
to display the contents of the memory card and delete the "S7_JOB.S7S" file and also
delete any directory folder (such as "SIMATIC.S7S" or "FWUPDATE.S7S").

copy the CPU device and paste it to the memory card.) Copying the CPU device to the
memory card opens the "Load preview" dialog.
