18.6.1 "General" Tab: Registering the OPC Server
With the OPC server, the default setting assumes an open system and assumes
that the user will adapt the settings when higher security is required.
If you select the "Security" tab with this setting for the authentication level, you will
see the entry "Everyone" if user-defined access right (see below in Section18.6.4).
