The memory card is an external memory medium, comparable to a disk.
Compared to the internal flash memory, the memory card features the
following advantages:
S The memory card is a portable storage medium. This means that, for
example, recipe data can be transported from one TP to another. In this
way, changes to configurations or firmware updates can be performed on
systems on which no configuration computer is immediately available for
transferring such data.
S Configurations can be loaded directly from the memory card because a
Touch Panel detects a card when inserted. In this case, the units access the
memory card first and then the internal flash memory.
S Its storage capacity of up to 16 MB provides space for large configurations
or a large number of recipe data records.
!

Panels of the same type. If not, you might provoke a system crash.
