Abstract
An Internet-based fill-level measurement value and diagnostic information polling system includes several field devices, a central server and a processing unit that is connected to the server by way of the internet. In response to a user inquiry the server generates a certificate and an associated data object that characterizes the data that may be polled by the user. In response to an inquiry by the user, with which inquiry the certificate is sent along to the server, the server automatically transmits the requested data to the user if a check of the certificate shows that the user is authorized to receive this.
