Normally, you should remove OB250 call from your S5 program before conversion, and then simply reprogram FB41 directly in the Step 7 project. But here you will find a suggestion from Late on how to re-use some of the parameters from your OB250 in the new FB41: /tf/WW/en/Posts/9017 Hope this helps, Daniel Chartier
