Removing History Collection

Anyone know why I can not delete some points in the history collection of a certain module? We are running Ver 11.3 and when I go into the modules history collection and try to delete some points I was recording is says an error has occured and gives me no reason.

  • Is your module part of a class?

    I would have to say no. I am not sure what that really means kind of new at this doing the learn as you go stuff.

    Did you made this module by copying other modules? or making it classless & changing something in it?

    Can you modify other things in the module & only history collection is giving error?

    Such errors occur sometimes, if the database has some ambiguities or disconnections in background.

    Try to export the module. Delete the complete module & reimport. This generally resolves any such issues.

    Well not sure why but I was able to delete the history collection in DeltaV Explore but not in Control Studio for that module. Don't know if its a bug in ver 11.3 or not. I was able to modify other things in the module and I don't recall if I had copied it or not from other modules.
