Abstract: A system for flexible operation of an automated plant, comprising at least one computer and a plurality of field devices for determining and/or monitoring physical or chemical, process variables. The computer and the field devices are embodied to be network capable and are connected, with one another via a network. A unique address in the network is associated, with each computer and each field device and communication occurs via a defined network protocol.

Abstract: A method for providing information via a computer system for evaluating suitability of a field device of the process industry for a certain application, characterized by steps as follows: a) indicating the application by inputting the measured substance and, in given cases, further properties of the measured substance; b) indicating and/or ascertaining a field device type, which is to be considered for the application; c) providing a database, in which at least one or more evaluations are furnished with reference to one or more on-site reviews of a field device of the input field device type in the indicated application; d) retrieving the evaluation in the database and e) outputting the evaluation relative to the indicated field device in the indicated application.

Abstract: A method for selecting a field device for ascertaining at least one process parameter of a measured material in process and automation technology, especially a process parameter such as flow, fill level, limit level, pressure, temperature, conductivity and/or ion concentration of a measured material, which field device is provided at a measuring point of a plant for ascertaining at least one process parameter, characterized by steps as follows: A identifying a first field device, which is suitable to determine the at least one process parameter of the measured material at the measuring point of the plant; B querying a first data set stored in a data memory relative to product features of the first field device, which enable ascertaining the at least one process parameter; C comparing at least one product feature of the first data set of the first field device with at least one corresponding product feature of a second data set of a second field device; and D specifying the second field device, to the extent t

Abstract: In a method for selecting products via the Internet, an Internet connection is established between a customer-side client-computer, which contains a planning module, and a manufacturer-side server, which contains a product database. After selecting at least one product line from the product database by querying of basic data via the Internet, a first identifier characterizing the selected product line is transmitted to the client-computer by the server. The specifying of a product of the product line is done with the help of the planning module by local querying of application data at the client-computer using the planning module. The first identifier can then be expanded to a second identifier uniquely characterizing the specified product. No transmitting of application data to third parties via the Internet is required.
