Entwicklung und Erprobung einer Schnittstelle zwischen der Messdatenerfassungs- und Automatisierungssoftware DIAdem von National Instruments und der Wasser/Dampf Stoffwertedaten-Unterbibliothek Libl97

The Institute of Safety Research (IfS) of the Forschungszentrum Rossendorf (FZR) e.V. is constructing a new large-scale multipurpose test facility TOPFLOW (Transient Two Phase Flow Test Facility). This facility will be probably put into operation in the next two months. For an effective evaluation of the start up experiments and the acceptance trials against the vendors FZR starts with the preparation of automated software tools for the measurement data logging and automation software DIAdem, which is distributed by National Instruments (NI). In a first step an interface for the coupling of a water/steam material property library LiblF97 of the university of applied science Zittau/Görlitz was developed.
This report describes the programming of the General Control Interface (GPI) and its coupling with DIAdem. Additionally the capability of this coupling in connection with autosequences for data evaluation was investigated. Further on effective methods for the TOPFLOW data evaluation were demonstrated and tested against a concrete example. Currently no TOPFLOW data are available. Therefore one selected NOKO experiment was evaluated and first practical experiences were collected. Even this example is easy understandable and clearly seen, it contains every step, which is necessary for the TOPFLOW data evaluation. This contains the opening of files, determination of water/steam material properties with the Dynamic-Link-Library LibIF97.dll, the linkage of different data channels and the generation of layouts for graphics and reports.

The tools presented in this report are an important steps for the evaluation of the experimental data of TOPFLOW. These tools will be adapted now for the assessment of the acceptance trails. Further on now the generation of the automated software sequences for the first scientific tests are developed.
