Abstract

A method for data communication between fieldbus devices and a control desk of an automation system by way of a data communication unit includes a first transmission step of the control desk transmitting data communication objects on the basis of the OPC UA protocol to first and/or second fieldbus device, and a first reception step of receiving the data communication objects on the basis of the OPC UA protocol. The data communication unit maps the data communication objects on the basis of the OPC UA protocol on first data communication objects on the basis of the fieldbus protocol. In a second transmission step, the data communication unit transmits the data communication objects on the basis of the fieldbus protocol to the first and/or second fieldbus device. In a second reception step, the first and/or the second fieldbus device receives the data communication objects on the basis of the fieldbus protocol.
