interpolation curve with 4 staging points

[a.bohne]

With a Wincc OA project Version 3.15 I need an interpolation curve with 4 staging points. This will be used for several datapoints, I created a master datapoint. At this master datapoint I cannot select more than two staging points, the combobox is deactivated. How can I solve this problem? If I delete the master datapoint I am able to choose up to 5 staging points at the msg_conv. But I need the master datapoint.

If you need a power config with more than 2 staging points you have to create an own power config.
The standard power configs in WinCC OA are defined for 2 staging points.
