Step 7 lad and stl viewing

[xio2go 0]

Currently using Step7 to program a CPU 314.  Since I have more experience with AB products I have been programming using the Ladder view.   After coding for a few days my view on all my code (except the first network) will only view in STL.  Has anyone come across this since the Siemens site is a maze of mixed German and Sales-speak.  Thanks in advance.

Fixed it but still confused.  Deleted all symbols in the symbol editor and my ladder returned.  Something is F'd up with that part of the program.  I didn't get any warning that a tag may be wrong or anything.  Maybe this will help the next fool that runs across this "Feature" of the Step 7 program....

There was a bug (feature) in an older version of Step 7 that would cause that problem. If you need the latest Service Pack, let me know.
