A method is for setting up temporary readiness of a field device for process automation to receive data in which a time interval is communicated to the field device during which it should be in transmit/receive mode. After expiry of this time interval, the field device switches back to a power-saving mode. As this time interval is freely selectable by a remote user, it is possible as a result to specify a suitable time for field device maintenance. As a result, it is possible to facilitate field device maintenance of battery-operated field devices which are in power-saving mode for the majority of the time.
