Abstract
A system includes a field device and a control device. The field device includes a field device controller and a field device transmitter. The control device includes a control device controller and a control device transmitter. The field device transmitter and the control device transmitter have a transmission path between them. The field device controller and the control device controller are adapted for bidirectional transmission of messages between one another according to a communication protocol via the field device transmitter, the transmission path, and the control device transmitter. The communication protocol implements the transmission of messages with a master role and a slave role. The field device controller implements the master role and the control device controller implements the slave role. A related method is also disclosed.
