S7-1200 memory card

Using memory cards

Before you can use a memory card, you first need to specify the card type. Depending on the card type you select, you can use the card for various tasks. You can choose from the following card types:

Program

If it is used as a program card, you can load the user program on the memory card. In this case, the internal load memory of the device is replaced by the memory card and the internal load memory is erased. The user program is then fully executable from the memory card. If the memory card with the user program is removed, there is no longer a program available.

Transfer

If it is used as a transfer card, you can transfer the user program from the memory card to the internal load memory of the CPU. You can then remove the memory card again.
