To save recipes in the internal memory, select "\Flash\" as the path in WinCC.
Note
Cyclic write access to the internal memory is not allowed
Cyclic write access to internal memory is not allowed, because this reduces the service life
of internal memory and of the HMI device.
To prolong the service life of your device, you should preferably use external memory cards
to store and log data, for example the SIMATIC HMI Memory Card.
Note
Number of allowed 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.
