C.2

Securely removing data

Before disposing of components of your automation system, you must securely delete all
data from the storage media of these components.
NOTICE
Data misuse resulting from non-secure deletion of data
Incomplete or non-secure deletion of data from data memories can result in data misuse by
third parties.
For this reason, ensure secure deletion of data from all storage media before disposing of
the product.
To delete all data from the data memories of the S7-1500 modules to be disposed of (CPU,
interface module, analog modules), reset the corresponding modules to their factory
settings. The "Reset to factory settings" function returns the module to its delivery state. The
function deletes all information that was saved internally on the module.
