The following data is saved in the internal memory:
● Operating system
● Project file
● License keys
● User administration
● Recipes*
● Other data, such as documents or media files
* To store recipes in the internal memory, select "\Flash\" as the path in WinCC.
Note
Cyclic write access to the internal memory is not permitted
Cyclic write access to internal memory is not permitted, because it reduces the service life of
the internal memory and of the HMI device, for
example, during configuration in which
system messages or user-defined messages are generated in the alarm buffer.
Configure an alarm window, check the number and frequency of the alarms that occur, and
adjust the configuration accordingly if you expect a permanent load on the internal memory
from alarms.
To prolong the service life of your device, you should preferably use external memory cards
to store and log data, such as the SIMATIC HMI Memory Card.
Note
Number of permitted files in the root directory of the internal memory
The number of files in the root directory is limited to 256. The number of files is not limited in
the subdirectories of the internal memory.
