That's probably why. My PLC is a 5370.
Such messy string definition , for ex. STRING_8 can contains up to 24 chars.
I was able to import it into a L330ERMS2, rework the UDT to v2. then import to my PLC.
It took less than a second to read all tags.
see picture & attached v2.
Yes, I can read the UDT structure with the tag reader. I'm trying now to read the data with ReadUDT.
Here is what I have as the structure.

I get this fault
