The memory cards and system memory cards are protected by a safety catch. The memory 
card and system memory card can be hot-swapped during ongoing operation of the HMI 
device.  
Note 
Potential loss of data 
The data on the memory card is lost if you attempt to remove it while the HMI device is 
accessing its data.
 
Do not remove the memory card while data is being accessed. Observe the corresponding 
alarms on the screen.

Only the SIMATIC
 HMI Memory Card ≥ 2 GB may be used as a system memory card. All
