Important note on application integrity:

STEP 7 V5.7 introduces the monitoring of application integrity. This option is activated as a default setting in STEP 7 V5.7. It checks whether installation data has been changed (e.g. attacks by malware).

If option packages or hardware for STEP 7 are installed that do not support this option, an error message is displayed when the project is opened:

If a new versions of the option packages or hardware that support this monitoring is not available, the application integrity monitoring should be temporarily disabled. This option can be found in the settings of the SIMATIC Manager of STEP 7 V5.7.
