Method and device for controlling a computer-aided arithmetic process in a technical system

A method for controlling a computer-aided computation process designed for interactive network-based use in a technical installation, comprising:

• in-putting measurement data of the technical installation via an interactive network-based operator control;
• utilizing a data store to receive and store the in-putted measurement data
• utilizing at least a portion of the measurement data from the data store in the computer-aided computation process and supplying result data from the computer-aided computation process to the data store;
• and
• communicating the result data from the data store to the client,
• wherein the interactive network-based operator control and the computer-aided computation process are decoupled to avoid active influence by the interactive operator control on the computer-aided computation process, and vice versa, wherein the decoupling is achieved by virtue of the interactive network-based operator control and the computer-aided computation process having the data store connected between them which is designed such that data are only stored into the data store or supplied from the data store on the basis of a command which has been sent to the data store, wherein data supplied to data store is provided a marker identifying the data as either input data or result data, wherein the method includes the step of checking the marker prior to supply of data from the data store, such that only data marked as input data is supplied from the data store to the computation process, and only data marked as result data is supplied from the data store to the interactive network-based operator control.
