CODESYS Trend API Example - Article no.000078
The sample project included in the CODESYS “TrendAPIExample.package” demonstrates how trend data can be read by means of the VisuTrendStorageAccess library. In this example, trend data is saved by the trend recording manager and then read as ST code by the VisuTrendStorageAccess API. In addition to querying historical data, active messaging is also possible when saving new data. The trend data can then be exported (example: CSV file) for later processing by other applications, for example by using the “CSV Utility” from the CODESYS Store.
