Abstract:
A method for data exchange via a bus system, wherein an amount of data determined for data exchange is composed of a plurality of data packets, which data packets are to be transmitted in a predetermined sequence from a second participant of the bus system to a first participant of the bus system, wherein, for data exchange, a first data query is sent from the first participant to the second participant, and wherein, as a reply to the first data query, a first data packet is sent from the second participant to the first participant. Especially after the first participant has received the first data packet, a second data query is sent from the first participant to the second participant via the bus system, and as a reply to the second data query, a second data packet is sent from the second participant to the first participant. The second data packet is either the first data packet or a data packet following the first data packet in the predetermined sequence. The first and the second data query contains, in each case, a parameter with a first or a second parameter value, and in the case in which the parameter values of the first and second data query agree, the first data packet is sent, while, in the case in which the parameter values of the first and second data query differ, the data packet following the first data packet in the predetermined sequence is sent.
Abstract:
A method for updating device descriptions for field devices in process automation technology by loading the required descriptions from an external server (S), by means of an application program, into a controller (for example, PC1; PC2).

Abstract:
A method for wireless data transmission between first and second transmission participants, wherein for wireless data transmission between the first and second participants alternately a first protocol and a second protocol are used, wherein the first protocol serves for unidirectional data transmission and the second protocol for bidirectional data transmission.
Abstract:
A method for operating a field device, which is connected by way of a data bus with a control system, by means of a graphical user interface and a device description file for a field device, the device description file includes two components, a data component and a presentation component, which are loaded together dynamically at run time into a browser, wherein the data component and the presentation component are produced together as a device description file, and the presentation component can be matched exactly to the functionality of the field device. In this way, the operation of a field device is considerably simplified.
Abstract:
A method for servicing a field device of process automation technology. The data exchanged between the field device and a servicing program is by means of at least one protocol, which has basic commands, via which basic functions of the field device can be invoked. Each field device which is compatible with the protocol has these basic functions available to it, and wherein only basic commands of the protocol are used to transfer data between the servicing program and the field device.
