A method is described for displaying the controller identification characters of a control unit in the ready symbol field of the operator information line on a network station. To accomplish this, the controller id from the gateway had to be passed to the network station. In addition, if the control unit did not send a controller id to the gateway, the default "four in the box" symbol had to be displayed on the network station.
