A method is provided for managing power for a wireless communication device. The method includes receiving a loop current at an insertion voltage at an initial input, the loop current being generated by a power supply. The method further includes comparing a reference voltage to the insertion voltage and generating a feedback signal based at least upon the comparison of the reference voltage to the insertion voltage. The method still further includes regulating the insertion voltage based at least upon the feedback signal, delivering charging power to an electrical storage element, wherein the charging power is a function of the insertion voltage and the loop current, and storing the charging power in the electrical storage element.

The invention relates to a method and a bus system for the interchange of device-specific data between fieldbus slaves of a first fieldbus and a fieldbus master of a second fieldbus, wherein the first fieldbus is connected for communication to a common Ethernet network via a first gateway and the second fieldbus is connected for communication to a common Ethernet network via a second gateway, wherein the communication via the Ethernet network occurs according to the client-server communication principle, wherein the first gateway reacts on the network side as a fieldbus master and on the Ethernet side as a web service server, and wherein the second gateway reacts on the fieldbus side as a fieldbus slave and on the Ethernet side as a web service client.

A gateway for a fieldbus system for connecting a controller to an industrial plant having a plurality of different components. The gateway includes at least one component interface via which the different components can be connected simultaneously or sequentially, a control interface to which a controller of the industrial plant can be connected, and a data processing module which, when at least one of the components is connected to the at least one component interface, is configured to identify the at least one component on the basis of a hardware address assigned thereto and to communicate with the at least one component via the component interface, and which, when the controller is connected to the control interface, is configured to communicate with the controller and to represent the at least one component with respect to the controller as a function-based representation. Furthermore, a fieldbus system is described.
