Warning from converting s7 to s5

I backup program from plc s5 100u and convert to step 7 v5.5 it have  warning.

Why show warning below.

I will solve the problem?

hi,

I never did this by my self. but I think that there is a problem with converting in the FB`s which are mentioned in this PDF-File. 

You should open these converted blocks an search for any error. Maybe there were some operations that are not supported by Step7. 

hope this helps,

regards,

Hello,

it seems like integrated FBs. First you can look if these blocks are used. If no - no problem.
