Abstract: An automation technology field device includes operating electronics and a plurality of parameters. The operating electronics are designed to operate the field device based on the parameters and obtain and process data based on the parameters. A firmware is a software container allocated to the operating electronics. The software container is designed to execute the installed code to establish, using the code, a communication connection to a distributed ledger via at least one of the outputs is a higher-level communication network, to integrate the field device in the distributed ledger-and to process and/or combine at least one part of the obtained and processed data into result data and to transmit the result data to the distributed ledger.

Abstract: A method for secure servicing of a field device (FD) of process automation technology. The field device (FD) has a web server (WS), via which the field device (FD) can be serviced, wherein the field device (FD) has a function (CAPTCHA) for distinguishing computers from humans, wherein, upon an accessing of the field device (FD) via the web server (WS), the function (CAPTCHA) for distinguishing computers from humans is executed, in order to assure that the accessing of the field device (FD) is being done by a human user.
