Abstract: Performing operating actions on a field device includes reading out identification information from the field device using an operating unit, selecting a use case by a first operator using the operating unit, (defining an operating action), and accessing the field device and executing the operating action defined in the selected use case. Status information relating to the use case from the operating unit is transmitted to a cloud-based platform, and the status information is confirmed by the first operator or by a second operator. Confirmation information is transmitted by the cloud-based platform to the operating unit via a second communication link. A report is created by the operating unit when confirmation information has been transmitted to the operating unit for each of the operating actions defined in the user case, and the report is linked to a digital image of the field device on the cloud-based platform.

Abstract: A method for transmitting security settings between a first automation engineering field device and a second automation engineering field device includes: identifying and authenticating an operator by means of a service unit; assigning an authorization group based on the identifying and authenticating of the operator; in the case, in which the operator is assigned the administrator authorization group: encrypting at least one security setting, which is present in cleartext, by the first field device; exporting the encrypted security setting; importing the encrypted security setting into the second field device; decrypting the encrypted security setting; loading the decrypted security setting into the data memory of the second field device and operating the second field device with the loaded security setting of the first field device.
