How can you set the password protection level in WinCC flexible configuration? Specifically, when an operator logs in, they should only be able to view and make limited modifications. Can engineers have more control? Is this possible?

A: Yes, it is achievable. To begin, go to "Runtime User Management" and create a new group under "Groups". Then, assign the appropriate permissions such as "Operation", "Management", and "Monitor" (you can also customize these as needed). These permissions can be assigned to one or more groups.

Next, create a new user under "Users" in the same "Runtime User Management" section. Assign them to the relevant user group based on their role. For example, operators may be placed in a group with limited access, while engineers could be in a group with higher privileges.

1. Define the user's permissions within the group they belong to in "Runtime User Management" in WinCC flexible. You can also set up usernames and passwords for each user here.

2. Regarding your question about whether the operator login can only see and modify content, and whether engineers can have more control — yes, this can be achieved effectively by properly configuring user groups and assigning different levels of access.

For managing multiple user permissions, it's important to understand that the terms "Operation", "Management", and "Monitor" in the group permissions are just labels. They are not hierarchical but rather represent different roles. This is similar to how permissions are managed in WinCC.

The more rights a user has, the higher their access level. For instance, if user A is part of the administrator group, they will have all three permissions — operation, management, and monitoring. User B, who belongs to a standard user group, might only have the operation permission by default. If a new group is created with "Operation" and "Monitor" permissions, then user C, who is part of that group, will only have those two permissions. Finally, when assigning security attributes to objects on the screen, you can ensure that user A has full access, user C has limited access, and user B has even more restricted access, depending on what is configured.
