Dear Yellowbeard, 

you may read through this post Download Error. I think you come from here.

The reason you have this problem should be due to some error happened cause the download unable to finish properly. 

If you open the chart reference-> PO Instance count - > there is something wrong there. 

The easiest way to resolve this issue is a full plc download. 

Or you can try to delete the FB of the DB3407 in CFC chart (locate it in cfc program), and download again, but I'm not sure whether it will resolve your issue or not. You may try. Before that, please do an archive. 

Dear Jaz Tai,

l entire dowload plc and solved this problem . Thank u.

Best regards
