Transferring your program with a memory card

S7-200 SMART CPUs 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 36) prior to inserting a memory card.
