Hi,

The function rights specify which functions a user or a user group may use in a specific role. You can link different function rights to multiple roles. You can also add user-specific runtime rights.

In the following example, you set up a user management for different users.

SIMATIC HMI WinCC Unified V19 - Example: Setup of the local user management

So, in your case, if the user-defined right "Test" is assigned to a role, and the logged in user does not have this role assigned, then he will not be able to press the protected button.

Ok,

so we don't have the possibility to create some complex function like the system-defined Runtime rights "Control panel access" which is given by the TIA program code, but we just declare access protection for that button, and the button performs the action that we have already set on that button.

Exactly.

I just saw that there is also an example that specifically talks about the configuration you are looking for to protect the button with a user-defined right:

Example: Configuring a button with access protection

Hope that helps!
