Method and system for providing device-specific operator data for an automation device in an automation installation

A method for providing device-specific operator data for an automation device connected to a data network via a network access switch in an automation installation, comprising:

• utilizing, by the automation device, at least one authentication credential having a first period of validity to authenticate itself to an authentication server in the automation installation including the data network and the network access switch;
• and
• prompting, based on an existence of current device-specific operator data having a second period of validity from an installation operator of the automation installation for the automation device, the current device-specific operator data to be linked to the authentication credential of the automation device and being linked to at least one authentication credential by a policy enforcement server in the automation installation including the data network and the network access switch, said automation device enquiring at regular intervals of time whether current device-specific operator data from the installation operator are existent for the automation device;
• wherein the first period of validity of the at least one authentication credential is different than the second period of validity of the current device-specific operator data.
