When ever I make this FB a multiple instance call from within another FB these pointers doesn't seem to work. When I monitor the instance DB of the calling FB the value at the Any pointer input shows: P#P 0.0 VOID 0. Is it not possible to use pointers with multiple instance FBs, and what is the cause of this?
