SIMATIC WinCC Open Architecture Forum

Hello,

in WinCCOA 3.18 a DP will collect by DPName in archive.
If i rename the DP, the archive data get lost.
Is it posibble to change the archive settings, do collect the data per DP-ID in stead of DP-Name like in earlier WinCC OA Versions.

Right now it is not possible to rename a datapoint and to preserve historical data when using NGA.
This feature is planned for future releases.
