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.
