The element-frame serves to control users from the user interface itself.
That is, typically this feature is provided to the SCADA programmer at the Security subsystem configuration,
but sometimes there is a need to provide this capability from the user interface and with a few restrictions on controlled users and their groups that this frame performs and generally provides:
- forming a list of controlled users;
- the ability to view and change user information for: name, full name, description, password and groups;
- adding new and deleting existing users.
