Abstract

The disclosure relates to a method for data transmission between a field device and an operating device, wherein the field device is designed to communicate with a higher-level device using a fieldbus protocol in order to perform an automation engineering task, and wherein the operating device is designed as a master for bit-serial point-to-point communication using a packet-based transmission protocol. It is proposed to encode the data to be transmitted according to the specification of the fieldbus protocol, and to carry it over the transmission channel using the packet-based transmission protocol.
