Patent ID: 8046499

Claim:
A method for transmitting data between a service tool and at least one field device comprising a sensor or an actuator via at least a fieldbus of process automation technology and an Internet databus, data on the fieldbus is transferred via a fieldbus protocol of the fieldbus and wherein data on the Internet databus are transferred via an Internet protocol, the method comprising the steps of: running a first application program in the at least one field device, the first application program operating in conjunction with the fieldbus protocol; exchanging data by the first application program in fieldbus telegrams via a fieldbus interface of the at least one field device according to the fieldbus protocol; running a second application program in the at least one field device, the second application program operating in conjunction with the Internet protocol, wherein the second application program maps the data of the Internet protocol onto the fieldbus protocol and transmits the data in the fieldbus telegrams via the fieldbus interface; and running a distributor module in the at least one field device that analyzes incoming fieldbus telegrams and forwards the incoming fieldbus telegrams to either the first or the second application program, depending on the content of the incoming fieldbus telegrams.
