Abstract: The invention claims a process and device for ensuring the operational readiness of a battery in which the battery is first electrically connected with a testing device, and is then tested with the testing device to determine whether the battery is passivated. If the battery is passivated, a procedure for de-passivation of the battery is performed. If the battery is not passivated, a point in time for the next testing of the battery is scheduled.

Abstract: The invention concerns a power supply system for a field device connected to a wire-line network with a radio module configured for data communication with an external unit, wherein the radio module is connected to the field device and has a power supply unit. The power supply adapter is provided with a power transmitter for the wireless power transfer to the power supply unit. The power supply unit is configured with a power receiver, while the power receiver and the power transmitter are inductively coupled for the power transfer.

Abstract: Stated is a charging-current regulating device for charging an energy storage device for a field device, and for regulating a charging current for the energy storage device, wherein regulating the charging current for the energy storage device takes place in such a manner that a limiting value relating to an input current of the field device is not exceeded. Regulating the charging current may take place in such a manner that energy storage takes place as quickly as possible and without overloading an input protection circuit of the field device.

Abstract: A control for a field device comprises a monitoring unit that is separate from a control unit for controlling the field device which monitoring unit, when the control unit is in a sleep mode, waits for an activation signal in order to switch the control unit to the operating mode.

Abstract: A field device acquires measured values and transferring data in an energy-controlled manner. A control device monitors the quantity of energy collected in the field device and triggers data transfer only when the quantity of energy collected has exceeded a predetermined threshold value. In particular, data transfer can take place at irregular intervals.

Abstract: A sensor housing for a field device includes a housing body and a solar module that may be put in place and removed. The solar module supplies the field device with electrical energy and may be placed on top of the housing body at various angles of rotation, as a result of which at the same time an electrical contact between the solar module and an energy storage device is provided.

Abstract: A control module of a field device includes an image processing module that is able to generate an image from process data of the field device, which process data are present in numerical form, which image can be displayed by a corresponding image display unit, for example the display of a PDA, in such a manner that a person can directly interpret the process data.
