The present invention relates to a communications system () with at least one node (), a control instance () and a shared communications medium (). The at least one node is designed to receive messages that are or were transmitted in a first transmission mode. This first transmission mode has a lower data transmission rate and/or transmission complexity than a second transmission mode. The control instance () determines a first of the nodes in order to transmit data thereto in the second transmission mode or in order to release the shared communications medium () for the first node to transmit data in the second transmission mode. The control instance communicates this to the first node by means of a message (). This message is transmitted in the first transmission mode.

The invention relates to a method for operating a processing device () that comprises a control unit () and at least one field device () connected to said control unit () for the purpose of exchanging data via a data exchange connection (), in which a field device () to be exchanged is replaced by another field device () to be inserted, and which comprises the steps of: generating an exchange signal (AS) using an exchange signal generator (), and transmitting said exchange signal (AS) to the control unit (). The invention also relates to a corresponding processing device and a control unit, field device, and exchange signal generator, as well as a computer program.
