How to determine the number of datapoints and types?

To determine the number of datapoints and types the flag “-report 6” (“–report dpidentification”) must be sent to the event manager using the WinCC OA console. The result informs about the byte consumption of the datapoints, number of datapoints and the number of dp-types.

The result is written to the manager-specific logfile (below you can find an example). For this example the number of datapoints and types can be readout from the lines “PVSS00event0: Datapoint Names: 598, String bytes: 9299, Total bytes: 23679” and “PVSS00event0: Datapoint Type Names: 240, String bytes: 3143, Total bytes: 7971”
