Hi,

In my project, TIA v14 SP1 is flagging almost every used input/output/Memento as ambigous data access.

This project uses ambigous data access only on mementos, so I feel confused.

Using cross reference, I cant find any other access, and typing other possible references don't help (ex : for %E0.0, typing %EB0, %EW0, %ED0). see screenshot attached, especially %EB2 range.

I don't understand how to get rid of this warning. 

Thanks for Helping.

Go to Show All Tags and order according to the addresses.

The software allow only one unique alias per address.

I have only one tag table.

And it shows unique entries for all my tags.

Even deleting tag usage (All the code refering to a tag), I still get the warning ...

Sorting again by address don't show duplicates.

Export (attached) does not show any duplicate tag.

Solved with :

1) full export

2) Delete all tags

3) Import

Project was surely corrupted (even if created with TIA V14 .SP1)

Hi,

I had the same problem on my TIA portal V15.1 after i added Technology Objects for motion control. 

For me i just  opened the tag table on Show all tags. Then I export and import the same file again.

I didn't delete the tags. It overwritten and the issue was solved.

Thanks for this solution.
