Abstract:
1. A method for updating device descriptions for different field devices, sensors or actuators, for determining and influencing process variables in process automation technology, whereby the field devices are connected via a field bus, whereby in each case a device description describes the functionality of the corresponding field device in a standardized language and whereby a control unit and an external server are employed, and whereby from the control unit a process activity is controlled or monitored and from which direct access to individual field devices is possible, wherein data transfer between the field devices and the control unit is carried out according to an international standard for field buses, comprising the steps: storing preconfigured device descriptions for specific applications of the field devices on a central server connected to the field bus via Internet, storing and running an application program in the control unit for servicing, configuring, parameterizing, or troubleshooting the field device, which application program requires device descriptions for field devices for its operation; downloading from the central server via the internet, by the application program in the control unit, the preconfigured device description of the corresponding field device to be serviced; wherein following a query of the device type of the field device corresponding device information for servicing the field device is downloaded from the central server.
