Abstract: Various embodiments of the teachings herein include a control device comprising: a wireless service interface; and a controller. The control device receives a radio signal generated by a device via a suitable radio connection using a further wireless interface and activates the wireless service interface once receiving the radio signal.

Abstract: One embodiment includes a control device for field devices connected to the control device via a communications network, e.g. a field bus. The control device comprises a wireless service interface (e.g. Wi-Fi interface). The control device is designed to receive a service signal generated by a field device and to activate the wireless service interface in response. Another embodiment includes a method for transmitting data to a control device for controlling field devices connected to the control device via a communications network. A wireless service interface of the control device is activated via a service signal generated by a field device and sent to the control device. After the activation of the wireless service interface, data is transferred from a tool (e.g. engineering tool, commissioning tool) via the wireless service interface.
