In the last step, the test run evaluation is carried out by means of the TestWork software. All data is logged in an SQL database whereby TestWork differentiates between process log database, alarm log database, configuration database and characteristic curve database. These databases are physically separated from each other and thus provide for even higher performance.
Data collection is primarily carried out by the real-time controller. This controller records the data, creates a timestamp and pushes the data through the Windows level for being logged to the SQL database. Each real-time controller also disposes of a sufficiently large buffer storage that temporarily logs data until the successful transfer to the SQL database.
In the evaluation, test runs can be filtered by diverse parameters, as for example by test item, test type or creator. The visualization of the selected test run is carried out in the high-performance TestWork Trend. Here, it is possible to zoom, modify time ranges, more exactly observe switching thresholds or define the section to be exported. As well, TestWork supports the creation of arbitrary characteristic curves by user-defined diagram types. The data export from the SQL database is realized by the Export Manager and is possible in diverse file formats. These include, amongst others, XML, XLS, XLSX, CSV or MDF.
