Abstract: The application discloses a power-over-Ethernet-based field device comprising a field device housing, an Ethernet connection so that the field device is suppliable with energy and can exchange data with the network, a voltage converter electronics for converting a voltage applied to the Ethernet connection to an operating voltage, and a field device electronics, which is supplied the operating voltage, and which serves for registering a process variable and communicating the registered process variable in the form of process data via the Ethernet connection, wherein the voltage converter electronics has a first means to heat the interior of the field device housing to a first threshold temperature and which contributes to converting the voltage applied to the Ethernet connection into the operating voltage so that the field device electronics can register the process variable and communicate the registered process variable in the form of process data via the Ethernet connection.

Abstract: A method for operating a wireless field-device network, comprising: wirelessly transmitting a process variable and an expected remaining running time from each field device to the other field devices within a field-device network so that in each field device the process variable and the expected remaining running time of the other field devices of the field-device network are stored; activating a second radio module of that field device which has the highest expected remaining running time, and deactivating the second radio modules of the other field devices within the field-device network; wirelessly transmitting the process variables of all field devices of the field-device network stored in the active field device, or at least a subset of the stored process variables, to the superordinate unit, which is not part of the field-device network, by means of the second radio module of the active field device.

Abstract: Disclosed is a primary-clocked switching power supply for converting an input voltage into an output voltage, comprising: a primary side circuit branch, where the input voltage can be applied; isolated from the primary side circuit branch, a secondary side circuit branch, where the output voltage is tappable; between the primary side and the secondary side circuit branch, a galvanic isolation; a fuse or circuit breaker arranged in the primary side circuit branch; a first switchable switch element arranged in the primary side circuit branch such that switching trips the primary side fuse or circuit breaker; and a monitoring unit connected with the first switch element and arranged in the primary side circuit branch and adapted to monitor a characteristic electrical signal determined by the second primary winding and, when the characteristic electrical signal exceeds a threshold value, to switch the first switch element.

Abstract: Disclosed is a field device adapter for wireless data transfer for connection to a field-device-internal interface provided for a display, comprising: an interface for connection to the field-device-internal interface; a radio module configured to wirelessly transmit a data packet on a low-power wide-area network, wherein the radio module is further configured to only transmit the data packet and not to receive any data packets; adapter electronics configured to limit an energy provided via the field-device-internal interface to a predefined value and to charge a stored energy source with the limited energy. The adapter electronics are further configured to monitor a state of charge of the stored energy source and, based on the state of charge, to provide the radio module with an energy originating from the stored energy source for transmitting the data packet.

Abstract: A field device of automation technology includes a field device housing and a field device electronics arranged in the field device housing. The field device also includes a first rechargeable battery arranged in the field device housing for energy supply of the field device electronics and a receiving unit with a receiving coil for receiving wirelessly inductively transmitted energy. The receiving unit is connected with the rechargeable battery so that the received, wirelessly inductively transmitted energy is storable, and is stored, in the rechargeable battery. The field device electronics is adapted in such a manner that energy supply occurs exclusively or at least partially from the first rechargeable battery and wherein the receiving unit and the receiving coil are adapted to receive wirelessly inductively transmitted energy as defined in a Qi standard 1.2.4 or a standard derived therefrom and to store such in the first rechargeable battery.
