SFC20,21: can not open it into rung

Hi everyone,

One more issue about SFC20,21. I try to make a test with that block but i could not open it into rung

Step 7 could not accept for me to drop it into nw. Can someone know reason why?

Thanks

Split from BLKMOV (SFC 20 ) vs FILL (SFC 21) ? .

Try this:

Select the rung, darg a "empty box" from the toolbar or press Alt+F9 alternatively,

in the empty box write "SFC20".

Perfecly, it worked

Thanks
