Transferring Your Program With A Memory Card - Siemens SIMATIC S7 System Manual

Transferring your program with a memory card

The standard S7-200 SMART CPU models support standard, commercial microSDHC cards
with a capacity ranging from 4 GB to 16 GB using the FAT32 file system format. You can use
a microSDHC card as a program transfer card for portable storage for your program and
project data.
Verify that the CPU is not running a process before inserting the memory card.
Inserting a memory card into a CPU in RUN mode causes the CPU to automatically
transition to STOP mode.
Inserting a memory card into a running CPU can cause disruption to process operation,
possibly resulting in death or severe personal injury.
Always ensure that the CPU is in STOP mode (Page 46) prior to inserting a memory card.
Creating a program transfer memory card
To program the memory card as a program transfer card, follow these steps:
1. Ensure that your network hardware and PLC connector cable are working, the CPU is
powered on and in STOP mode, and that PLC communication is operating properly
(Page 34).
2. If not already inserted, insert a microSDHC memory card in the CPU. You can insert or
remove the memory card while the CPU is powered on.
3. Download (Page 45) the program to the PLC, if not already downloaded.
4. Click the Program button from the Memory Card area of the PLC menu ribbon strip.
5. Select which of the following blocks (or all) to store on the memory card:
– Program block
– Data block
– System Block (PLC configuration)
