A radio unit for a plant of process automation technology. The radio unit has a power circuit, which serves to derive first and second supply voltages from a voltage source, wherein the power circuit has a first output, via which the first supply voltage is tappable to serve for driving an operating electronics of the radio unit, wherein the power circuit has at least a second output, via which the at least a second supply voltage is tappable to serve for driving at least one field device connectable to the second output.

Radio unit with a power circuit for voltage supply and method for operating such a radio unit

A method for monitoring charge level or remaining capacity of a battery pack, a disposable battery or a rechargeable battery, which is used to supply energy for an automation technology, field device having a data storage unit associated with the battery pack, disposable battery or rechargeable battery. Specific information about the battery pack, disposable battery or rechargeable battery is stored in the data storage unit and process-specific and operation-specific information about energy consumption is written to the data storage unit. In the case of the battery pack, disposable battery or rechargeable battery being used in a second automation technology field device, remaining service life of the battery pack, the disposable battery or the rechargeable battery is calculated and output on the basis of the process- and operation-specific information.

Method for monitoring the state of charge, or remaining capacity, of a disposable or rechargeable battery

A method for integrating a field device of automation technology into a radio network composed of a plurality of field devices, wherein the field device to be integrated switches, or is switched, at start-up, respectively, first start-up, into a special start-up mode, wherein, in the special start-up mode, a peer to peer connection to a service device or to a selected field device is produced on a specific channel and wherein integration data are transmitted from the service device or the selected field device to the field device to be integrated and/or diagnostic data of the field device are transmitted to the service device or to the selected field device.

Method for servicing a field device of automation technology in a radio network

A method for monitoring the remaining service life of a battery used for operating a field device in automation technology. The present power consumption of the battery is ascertained. Then, during a first phase of life, power consumption of the battery ascertained during operation of the field device is compared with a predetermined threshold value. In the case of exceeding the predetermined threshold value, during a second phase of life, the battery is exposed to defined load spikes at predetermined time intervals. Voltage collapses corresponding to the defined load spikes are detected, and a warning report is generated when the voltage collapses reach a predetermined maximum limit value.
