Hello,

In order to prevent unwanted downloads to the new CPUs (by hardware and not password), what is the alternative solution for the RUN-P selector.

Thanks,

There are two possible ways to handle this. If you want software control over the ability to download or change a program instead of using RUN-P, you can:

1) Use block SFC109 (Protect) and write a "1" (W#16#1) to the protection parameter. This only works if you have your protection level set to Level 1 (no protection) on the Protection tab in the Controller Properties window.
2) Use the Protection tab in the Controller Properties to set protection without a password (Level 2): fhttps://support.industry.siemens.com/cs/document/16650102/what-options-exist-for-assigning-passwords-?dti=0&lc=en-WW
